30 March 2017 - Case No. I-15 U 66/15
The claimant is the owner of European patent EP B1, allegedly covering data transmission technology under the GPRS standard. The defendants produce and market devices using the GPRS standard. On 10 April 2013, the claimant made a commitment towards ETSI by declaring to grant a license on FRAND terms regarding, inter alia, patent EP B1. In various letters and meetings between 2012 and 2015, the claimant informed the parent companies of the defendants about its patent portfolio and made an offer, but no licensing agreement was entered into. These interactions took place before the CJEU handed down its Huawei v. ZTE ruling in July 2015. On 3 November 2015, the District Court granted an injunction order.  The District Court also held that the defendants were liable for compensation in principle and ordered them to render full and detailed account of its sales. Further, the District Court ordered a recall and removal of all infringing products from the relevant distribution channels.
The defendants lodged an appeal with the Higher Regional Court of Düsseldorf. They argued, inter alia, that the District Court had not taken into account the procedural requirements set out by the CJEU in the decision Huawei v. ZTE  and that the claimant had not made a license offer on FRAND conditions.  The Higher Regional Court of Düsseldorf partially granted the appeal. It held that the defendants were under an obligation to render accounts and that they owed compensation in principle.  However, it held that the defendants were under no obligation to recall and remove the products from the relevant distribution channels because the claimant was in breach of its obligations under EU competition law (‘kartellrechtlicher Zwangslizenzeinwand’).  The Higher Regional Court did not have to decide about the injunction order because the parties had agreed to settle the matter in this regard (the patent had expired in September 2016). 
B. Court’s reasoning
1. Market Power
The Higher Regional Court held that the claimant was a dominant undertaking within the meaning of Art 102 TFEU.  In the eyes of the court, proprietorship of an SEP does not automatically constitute a dominant market position because not all SEPs necessarily influence competition in the downstream product market.  Rather, it needs to be ascertained whether or not market dominance exists in respect of each SEP individually. A dominant market position exists, for example, if it would not be possible to successfully market a competitive product without using the respective SEP, or if compatibility and interoperability under the standard could not be guaranteed. In contrast, a dominant position does not exist if the technology covered by the SEP is only of little importance for consumers in the relevant market.  On this basis, the Higher Regional Court had no doubts that the claimant was in a dominant market position  because the patent in question was related to data transfer, an essential function of the GPRS standard. 
2. Notice of Infringement
The Higher Regional Court held that the claimant had given proper notice of infringement under the CJEU requirements. According to the court, the procedure set out by the CJEU in the Huawei v. ZTE ruling applied to transitional cases (i.e. proceedings that had commenced before the CJEU decision, but where the decisions were handed down after).  The District Court had wrongfully assumed that the Huawei v. ZTE principles did not apply to the case at hand. CJEU decisions pursuant to Art 267 TFEU apply ab initio (‘ex tunc’) and thus to transitional cases.  The Higher Regional Court argued that the Huawei v. ZTE case itself had been of a transitional nature and that the CJEU had been aware of the diverging principles created by the German Federal Court of Justice in the Orange Book Standard decision in 2009.  Nevertheless, the CJEU had not distinguished between transitional and ‘new’ cases. As a consequence, the claimant was under an obligation to notify the defendants of the infringement. The written correspondence between the parties from 2012 and 2013 met this requirement 
The Higher Regional Court also held that it was sufficient to notify the defendants’ parent companies.  The claimant can reasonably expect that the parent company will pass on the respective information to all subsidiaries that are active on the relevant product markets. Requiring the claimant to give additional notices to the subsidiaries would be an unjustified formality (‘bloße Förmelei’). 
3. The Defendant’s Willingness to Enter into a License Agreement
As a consequence, the defendants were under an obligation to declare their willingness to enter into a license agreement on FRAND terms.  Several months had passed between the notice of infringement and the defendants’ declaration of willingness. However, the defendants had made it clear in an email from December 2013 that they were willing to enter into a license agreement. In the eyes of the Higher Regional Court, this was sufficient because there was ample time between this declaration and the commencement of proceedings in 2014.
In the further course of the negotiations, the rejection of certain license terms by the defendant was not necessarily an indicator for general unwillingness.  The defendant’s willingness needs to be seen in the overall context of the case. Unwillingness would be demonstrated only if the defendant definitively and finally rejects the claimant’s offers (the ‘last word’).  The Higher Regional Court held that the statements made by the defendants in the course of the negotiations did not justify such a conclusion. 
4. The SEP Owner’s Licensing Offer and the Standard Implementer’s Reaction
The Higher Regional Court held that the District Court had been incorrect to leave open the question as to whether the claimant’s offer had been FRAND.  The Higher Regional Court took the view that the CJEU had established an intricate system of consecutive actions that the parties must take. A claimant needs to make an offer on FRAND terms only if the defendant declared its willingness to enter into a license agreement on FRAND terms. Similarly, a defendant is under an obligation to make a counter-offer on FRAND terms only if the claimant made an offer on FRAND terms.  According to the Higher Regional Court, this view flows from the wording of the Huawei v. ZTE ruling that relates the content of offer and counter-offer (‘such an offer’; ‘responded to that offer’).  An SEP owner who has given a commitment to an SSO to offer FRAND licenses can be expected to make a FRAND offer that can reasonably be accepted by the defendant. In addition, a defendant needs to be able to assess whether the conditions of the claimant’s offer are FRAND. Requiring a defendant to make a FRAND counter-offer no matter what the claimant had offered earlier would be a contradiction of this basic proposition of the Huawei v. ZTE ruling.  Thus, it was necessary to have a decision in respect of the conditions of the claimant’s licensing offer.
The Higher Regional Court held that the claimant’s licensing offer did not meet FRAND requirements  because it discriminated against the defendants.  The court reiterated that infringement courts cannot limit their assessment to a summary review of whether the conditions were not evidently non-FRAND. Rather, infringement courts need to make a full assessment of the license conditions. 
The court held that dominant undertakings are under no obligation to treat all business partners in exactly the same way.  SEP owners have discretion regarding the license fees that they charge.  Different treatment of licensees is accepted if it can be justified as a result of normal market behavior.  Further, license conditions can be abusive only if they are significantly different between licensees.  These principles also apply to SEP owners who have given a FRAND declaration because this commitment refers to Art 102 lit. c) TFEU.  The burden of proof for such substantially unequal treatment lies with the defendant,  whilst the onus is on the claimant to prove that this unequal treatment is justified.  However, as the defendant will typically not have the necessary information, the claimant is under an obligation to provide information as to which competitors have been granted licenses and on what terms.  On this basis the Higher Regional Court concluded that the claimant had treated the defendants significantly differently from their competitors  without having a proper justification.  In particular, the claimant could not prove that discounts given to a competitor were common in the industry,  or that these discounts were a result of the particularities of the case.

7 June 2017 - Case No. HP-2014-000005
A. Facts and Main Judgment
The claimant is a company that grants licenses for patented technologies in the telecommunications industry. The patents at issue relate to telecommunication network coding and procedures. In 2014, the claimant made a declaration under the ETSI IPR Policy that it was willing to grant licenses on FRAND terms. There were five technical trials relating to the validity, infringement and essentiality of these patents and one non-technical trial relating to competition law issues, FRAND issues, injunctive relief and damages for past infringements.Unwired Planet v. Huawei  EWHC 711(Pat), available at http://www.bailii.org/ew/cases/EWHC/Patents/2017/1304.html In its decision on 5 April 2017 (the ‘main judgment’), the Patents Court (Birrs J) held that two patents were valid and that they had been infringed, and that the claimant was in a dominant position, but had not abused this position. The court stated that a final decision about an injunction to restrain patent infringements should be made separately. A few weeks after the main judgment, a license representing the FRAND terms between the two parties was prepared (the ‘settled license’), but had not yet been entered into.  Further, the defendant offered to give an undertaking to the court to enter into the license settled by the Patents Court or any other court. 
In its subsequent decision on 7 June 2017 (the case at hand), the parties argued whether the court should grant an injunction order given the existence of the settled license. Other minor issues of the case related to damages, declaratory relief, costs and permission to appeal.  The court granted an injunction for infringements of patents EP (UK) 2 229 744 and EP (UK) 1 230 818 (the ‘final order’).  The injunction order would be discharged if the defendant entered into a FRAND license and it would be stayed pending appeal. The court also declared that the settled license represented the FRAND terms in the given circumstances between the parties and that the defendant had to pay GBP 2.9 million of the claimant’s costs. Permission to appeal was granted to the defendant in respect of three issues and to the claimant in respect of one issue. 
B. Court’s Reasoning
The main issue considered by the court was the interplay between the injunction, the settled license and the undertaking offered by the defendant. Patent EP (UK) 2 229 744 will expire in 2028. The settled license’s expiry date is 31 December 2020,  which would put the defendant in a difficult position if it attempts to renegotiate the license while the injunction is still in place. The defendant would even risk being in contempt of court if it continued to sell equipment if there was an argument that the license had come to an end for other reasons (e.g. repudiatory breach of contract).  However, the court took the view that it cannot be said that the defendant must be free to sell products if the license has ceased to exist.  Similarly, it cannot be said with certainty that the claimant must have an injunction at that date.
Thus, the court considered what the correct form of injunction in respect of a FRAND undertaking should be when a court has settled a license but the defendant has not entered into it (‘FRAND injunction’).  The court held that the FRAND injunction should contain a proviso that it will cease to have effect as soon as the defendant enters into the FRAND license. The injunction should also be subject to an express liberty to either party to return to court in the future if the FRAND license ceases to exist or expires while the patent is still valid. 
The court also held that despite the court’s discretion as to whether an injunction is granted, an injunction is normally effective, proportionate and dissuasive in IP cases.  Although the practical effect of a defendant’s undertaking and an injunction are similar, rights holders usually insist on an injunction.  One reason is that it involves a public vindication of the claimant’s rights.  As the claimant has been forced to come to court, an offer of undertaking after judgment is usually considered too late.  In this case, the defendant had maintained throughout the negotiations and the trial that it was under no obligation to accept a worldwide license.  Thus, according to the court, the right thing to do was to grant a FRAND injunction which will be stayed on terms pending appeal.
2. Other Issues
The court held that the issue of damages is closely related to the main issue.  If the defendant entered into the settled license, all payments would be covered by the license. If the defendant did not enter into the settled license, an order for damages is required. As a consequence, the court order should be in the same form as the FRAND injunction (stayed pending appeal and ceasing to have effect if the parties enter into the settled license). 
The parties also disagreed about the wording of the court declaration regarding the FRAND terms of the settled license.  The court dismissed the defendant’s suggestion as too complicated and the claimant’s suggestion as incomprehensive. Instead, the court declaration would be ‘the license annexed to the judgment represents the FRAND terms applicable between the parties in the relevant circumstances’.  Further, the court rejected the defendant’s petition to make a declaration that the claimant had not abused its dominant market position.  It took the view that the main judgment made a clear finding on this issue in summary paragraph 807(17).
Further, the parties disagreed about the extent of the defendant’s obligation to bear the claimant’s costs. The claimant argued that it should be regarded as the successful party so that the defendant had to pay its costs (GBP 6.4million).  The defendant argued the claimant had been clearly wrong regarding the applicable FRAND rate  and the appropriate thing would be to make no cost order. The court rejected the idea that there was no overall winner (as argued by the defendant) because the claimant was successful on the issues of the nature of the license and the existence and abuse of market dominance.  The ensuing question was whether any deductions were appropriate.  The court held that neither party had offered terms that were essentially FRAND.  However, the rates offered by the claimant were significantly further away from the end result than the rates offered by the defendant.  Thus, the defendant’s costs in relation to the FRAND rate issue were not recoverable by the claimant.
The fifth and final issue was in respect of permission to appeal. The court granted the defendant permission on three grounds: first, the necessity of granting a global license (including the court’s view that there is only one applicable license fee);  second, the hard-edged non-discrimination point;  and third, the issue of injunctive relief and abuse of market dominance under the CJEU ruling Huawei v. ZTE.  Conversely, the claimant was granted permission to appeal on the blended global benchmark issue (using a blended global rate as a benchmark, leading to the question whether another discount for the Chinese market should given).

English court decisions
4 May 2017 - Case No. HP-2014-000005
The claimant is a company that grants licenses for patented technologies in the telecommunications industry. The patents at issue (EP (UK) 2 229 744, EP (UK) 2 119 287, EP (UK) 2 485 514, EP (UK) 1 230 818, EP (UK) 1 105 991, EP (UK) 0 989 712) relate to telecommunication network coding and procedures  . Most were part of a large patent portfolio that the claimant had acquired from a major telecommunications company in 2013.  In 2014, the claimant made a declaration under the ETSI IPR Policy that it was willing to grant licenses on FRAND terms. There were five technical trials relating to the validity, infringement and essentiality of these patents. This summary focuses on the non-technical trial addressed competition law issues, FRAND issues, injunctive relief and damages for past infringements. 
In April 2014 the claimant made an open offer to the defendant, a major international smartphone manufacturer, to grant a license in respect of the claimant’s entire global patent portfolio (containing SEPs and non-SEPs). The defendant refused the offer, contending that there was no patent infringement, that the patents were not essential, and that they were invalid. The defendant also argued that the offer was not FRAND and thus did not constitute an abuse of a dominant market position under Art. 102 TFEU. In July 2014 the claimant made a further offer, limited to the claimant’s SEPs. Again, the defendant refused, arguing that the license conditions were not FRAND.  In June 2015 both parties made further offers. These offers were the result of directions from the court. The claimant offered a worldwide portfolio license while the defendant wanted to limit the territorial scope to the United Kingdom.  Between August and October 2016 the parties exchanged further offers without reaching an agreement. 
The Patents Court (Birrs J) held that the claimant was in a dominant position, but did not abuse this position.  The defendant was not prepared to take a license on FRAND conditions and the claimant was not in breach of competition law. Thus, the court held that a final injunction to restrain patent infringements should be granted. An injunction for infringements of patents EP (UK) 2 229 744 and EP (UK) 1 230 818 was granted on 7 June 2017. 
- Court’s reasoning
- Market power
The court defined the relevant market for assessing dominance as a distinct market for licensing each SEP individually.  European case law indicated that owning an SEP could be a rebuttable presumption for the existence of a dominant position.  The claimant’s pleaded position was a non-admission of dominance rather than a denial coupled with a positive case to the contrary. It was the view of the court that this was insufficient to rebut the presumption. In particular, the claimant’s argument of countervailing buyer power was unconvincing because it had not been supported by a proper economic analysis. 
- SEP Proprietor’s Licensing Offer
- FRAND Declaration as Conceptual Basis
The court pointed out that that the FRAND undertaking also applied in the case that the SEP proprietor was not in a dominant position. It held that the FRAND undertaking operated as a practical constraint on a SEP owner’s market power.  The ETSI declaration made by the SEP proprietor is also the starting point for determining the FRAND rate. The underlying issue, which is discussed at length by the court,  is if such a declaration forms a contract and whether that contract can benefit third parties. The court acknowledged that the legal effect of this declaration, in particular its enforceability, is a controversial issue under French law.  However, the court reasoned that the FRAND declaration is an important aspect of technology standardisation. Holders of SEPs are not compelled to give a FRAND declaration. If they do, the undertaking would be enforceable and irrevocable due to public interest. 
The court applied a procedural approach to FRAND. It emphasised that FRAND describes not only a set of license terms, but also the process by which a set of terms are agreed.  It applies to both the SEP-holder and the implementer/defendant. In particular, this approach allows for starting offers that leave room for negotiation. On the other hand, making extreme offers and taking an uncompromising approach which prejudices fair, reasonable, and non-discriminatory negotiation is not a FRAND approach.  This approach also means that the SEP proprietor is under an obligation to make a FRAND offer and to enter into FRAND license agreements. 
- ‘True FRAND Rate’
The court considered that there is only a single set of terms for a given set of circumstances that would meet FRAND conditions (‘true FRAND rate’).  This eliminates the so-called Vringo-problem,  i.e. if FRAND were a range there would be two different but equally FRAND offers. Thus, if the court would grant or not an injunction, it would be unfair for the alleged infringer or SEP holder respectively. 
The court was of the opinion that the true FRAND rate approach does not cause problems under competition law. Theoretically, if only one set of terms is truly FRAND, and if FRAND also represents the line between abusive and non-abusive conduct under Art. 102 TFEU, then every agreed SEP-licence could be at serious risk of being abusive.  However, the court took the view that FRAND-compliance and compliance with Art. 102 TFEU are not the same thing (the court pointed out that the CJEU in the Huawei ruling appears to equate an obligation to make a FRAND offer with compliance with Art 102 TFEU).  Since Art. 102 TFEU condemns excessive pricing,  a royalty rate can be somewhat higher than the true FRAND rate and still not be contrary to competition law. Conversely, for a breach of competition law, it will be necessary but not sufficient that the rate is not the true FRAND rate. 
The court held that the correct approach is to start from a global rate as a benchmark and to then adjust this rate as appropriate.  It distinguished between two concepts of discrimination. First, the ‘general’ concept of non-discrimination describes an overall assessment of FRAND which can be used to derive the benchmark mentioned above.  It is based on the intrinsic value of the patent portfolio, but it does not depend on the licensee. The court held that this benchmark should be applied to all licensees seeking the same kind of license. 
Second, the ‘hard-edged’ non-discrimination obligation, which takes into account the nature of the potential licensee,  is a distinct concept that could be used to adjust license terms. However, the court held that the FRAND declaration does not introduce such a hard-edged non-discrimination concept.  If, contrary to the view taken by the court, the FRAND undertaking did include hard-edged non-discrimination, a licensee could only have the right to a lower rate granted to another licensee (i.e. a specific non-discrimination obligation resulting from the FRAND declaration) if the difference would otherwise distort competition between the two licensees. 
- Territorial Scope of License
The court held that the defendant’s offer that was limited to UK licenses was not FRAND. In the court’s opinion country by country licensing is inefficient for goods such as mobile telecommunications devices that are distributed across borders.  It would also be inefficient to negotiate many different licenses and then to keep track of so many different royalty calculations and payments. No rational business would do this, if it could be avoided.  This was illustrated by the fact that the vast majority of licenses introduced in the trial were worldwide licenses.  Further, it is common ground that the industry assesses patent families rather than individual patents within the family. Assessing portfolios on a family basis inevitably involved tying a patent in one jurisdiction with a patent in another.  Thus, according to the court, a worldwide license would not be contrary to competition law. As willing and reasonable parties would agree on a worldwide licence, the insistence by the defendant on a license which was limited to the UK was not FRAND. 
- FRAND Declaration as Conceptual Basis
- Market power
- Court’s reasoning
- Comparable agreements and reasonable aggregate royalty rate
The court held that for determining the royalty rate, the evidence of the parties would be relevant, including evidence of how negotiations actually work in the industry.  Other freely-negotiated license agreements might be used as comparables.  This may be compared with a top down approach  can also be used in which the rate is set by determining the patentee’s share of relevant SEPs and applying that to the total aggregate royalty for a standard, but this may be more useful as a cross-check.  Royalty rates determined by other courts might be useful as persuasive precedents. However, in the eyes of the court, a license rate determined at a binding arbitration does not carry much weight as to what parties are usually paying.  License agreements must meet certain criteria to be comparable.  First, the licensor is the claimant. Second, the license agreement is recent. However, it is not necessary that the licensee is the defendant or a comparable company because different market participants have different bargaining powers, which is reflected in the negotiations and the resulting royalty rates.  Finally the court confirmed that a royalty based on the handset price was appropriate and implied a reasonable aggregate royalty rate of 8.8%of the handset price. The court found that the 8.8% was reasonable, in part, because the aggregate implied by either party’s case was higher (10.4% and 13.3%). 
- Principles derived from Huawei v. ZTE
The court also provided a compiled overview of its interpretation of the Huawei v. ZTE ruling.  In the eyes of the court, the ‘willingness to conclude a licence on FRAND terms’ refers to a willingness in general. The fact that concrete proposals are also required does not mean it is relevant to ask whether the proposals are actually FRAND or not. If the patentee complies with the procedure as set out by the CJEU, then bringing a claim for injunction is not abusive under Art 102. But even if sufficient notice is given, bringing a claim can constitute an abuse because complying with the procedure does not mean that a patentee can behave with impunity. In other words, there might be other aspects that make the claim abusive. Conversely, bringing such a claim without prior notice will necessarily be abusive. Significantly, the court held, the legal circumstances of this case differ from the circumstances assumed by the CJEU in a crucial respect. A FRAND undertaking can be effectively enforced irrespective of Art 102. The defendant does not need Art 102 TFEU to have a defence to the injunction claim.

English court decisions
16 April 2018 - Case No. HP-2017-000048
The claimant, Conversant, is a licensing firm incorporated in Luxembourg. The defendants are two major Chinese telecoms equipment and handset manufacturers, Huawei and ZTE, and their English affiliates. After years of negotiations that failed to result in licenses for claimant’s portfolio of Standard Essential Patents (SEPs) reading on ETSI wireless telecoms standards (and comprising inter alia Chinese and UK patents),Conversant v. Huawei and ZTE EWHC 808 (Pat) para 5. the claimant filed an action for infringement of four of its UK SEPs before the High Court of Justice (Court), and requested the Court to define Fair, Reasonable and Non-Discriminatory (FRAND) terms for its global SEP portfolio.  The defendants in separate proceedings initiated in China disputed the validity, essentiality and infringement of claimant’s Chinese patents. Since the defendants failed to unequivocally commit to conclude licenses on FRAND terms decided by the Court, the plaintiff amended its pleading to include injunctive relief, unless and until the defendants comply with the Court’s FRAND determination. 
The judgment at hand involves the defendants’ challenge to the Court’s jurisdiction to decide upon the terms of a global portfolio license. According to the defendants, a UK court has no jurisdiction to decide on the validity and infringement of foreign (in the present case: Chinese) patents.  Furthermore, the defendants claim that the jurisdiction most closely connected to the case is China which is the centre of the defendants’ manufacturing activities as well as the jurisdiction where the bulk of their sales takes place. 
B. Court’s Reasoning
The court dismissed the defendants’ challenge of jurisdiction. Following the reasoning of Birss J in Unwired Planet,Unwired Planet v. Huawei EWHC 711 (Pat) paras 565-67 Carr J held that, although issues of validity of patents granted in foreign jurisdictions are not justiciable in the UK, nevertheless the issue of validity should be distinguished from the issue of the determination of a global portfolio license on FRAND terms. According to Carr J, the defendants are free to challenge the validity, essentiality, and infringement of claimant’s Chinese patents in separate proceedings before Chinese courts; the pending issues of validity, essentiality and infringement do not preclude, however, the Court from determining FRAND terms for a global license and providing a mechanism of adjusting the royalty rate according to the validity and infringement decisions of courts in other jurisdictions.Conversant v. Huawei and ZTE(n. 1) paras 17 et seq. Furthermore, the defendants’ justiciability defense, were it to be accepted, would make it impossible for patent holders with a global portfolio of SEPs to obtain relief in the form of court-determined FRAND terms for a global license, since they would need to commence litigation on a country-by-country basis.  Forcing the patent holder to seek separate licenses for every individual country where it held SEPs could be characterized as a ‘hold-out chater’, in the eyes of the Court. 
Moreover, the Court seized jurisdiction over the case on the ground that the plaintiff’s claim concerns four patents granted in the UK; the issue of relief for patent infringement, and in particular whether such relief will take the form of setting FRAND terms for a global license, is to be decided in the context of a ‘FRAND trial’, after a decision on infringement is reached.  Were the defendants’ argument to be accepted, the Court would, in effect, be barred from deciding on the infringement and the proper relief for patents granted in the UK.  Besides that, the Court also held that the defendants’ failed to establish that the Chinese courts would be the appropriate forum for the dispute.  In this respect, given that royalty rates for telecommunication SEPs are usually lower in China than in other countries, the Court particularly pointed out that no holder of a global SEP portfolio would voluntarily prefer to submit to determination of a FRAND license for the entirety of portfolio in a country, where the rates applied would be lower than the rest of the world.

English court decisions
23 October 2018 - Case No. A3/2017/1784,  EWCA Civ 2344
The Claimant, Unwired Planet International Limited, holds a significant portfolio of patents which are essential for the implementation of the 2G/GSM, 3G/UMTS and 4G/LTE wireless telecommunications standards (Standard Essential Patents, or SEPs). The Defendants, Huawei Technologies Co. Ltd. and Huawei Technologies (UK) Co. Ltd., manufacture and sell mobile devices complying with the above standards worldwide.
Starting in September 2013, the Claimant contacted the Defendants several times, requesting the latter to engage in discussions for a licence regarding its SEP portfolio.  In March 2014, the Claimant sued the Defendants as well as Samsung and Google for infringement of five of its UK SEPs before the UK High Court of Justice (High Court).  The Claimant also initiated parallel infringement proceedings against the Defendants in Germany. 
The High Court conducted three technical trials first, focusing on the validity and essentiality of four of the SEPs in suit.  By April 2016, these trials were completed; the High Court held that two of the SEPs in suit were both valid and essential, whereas two other patents were found to be invalid.  The parties agreed to postpone further technical trials indefinitely. 
In late 2016, the trial concerned with questions regarding to the licensing of the SEPs in suit commenced between the Claimant and the Defendants. Over the course of these proceedings the parties made licensing offers to the each other. However, they failed to reach an agreement. The Defendants indicated they were willing to take a licence under Claimant’s UK patent portfolio, whereas the Claimant contended that it was entitled to insist upon a worldwide licence. 
In April 2017, the High Court granted an UK injunction against the Defendant, until such time as it entered into a worldwide licensing agreement with the Claimant on the specific rates, which the court determined to be Fair, Reasonable and Non-Discriminatory (FRAND)  in accordance with the undertaking given by the Claimant towards the European Telecommunications Standards Institute (ETSI).  Pending appeal, the High Court stayed the injunction. 
Shortly after the High Court delivered its decision, the Defendants began proceedings against the Claimant in China, which are still pending. 
With the present judgment, the UK Court of Appeal dismissed the Defendants’ appeal against the decision of the High Court. 
B. Court’s reasoning
The Defendants appealed the decision of the High Court on the following three grounds:
1. The High Court’s finding that only a worldwide licence was FRAND is erroneous; the imposition of such a licence on terms set by this court based on a national finding of infringement of UK patents is wrong in principle. 
2. The offer imposed to the Defendants by the High Court is discriminatory in violation of Claimant’s FRAND undertaking, since the rates offered are higher than the rates reflected in the licence granted by the Claimant to Samsung. 
3. The Claimant is not entitled to injunctive relief; by bringing the infringement proceedings against the Defendants, without meeting the requirements established by the Court of Justice of the European Union (“CJEU”) in the matter Huawei v ZTE  (Huawei judgment) before, the Claimant abused its dominant market position in violation of Article 102 of the Treaty on the Functioning of the European Union (“TFEU”). 
Notably, the High Court’s determination of the rates which apply to the worldwide licence that the court requested the Defendants to take was not challenged by any of the parties to the proceedings. 
1. Worldwide licences
The Court of Appeal disagreed with the Defendants’ notion that imposing a worldwide licence on an implementer is wrong, because it amounts to an (indirect) interference with foreign court proceedings relating to patents subsisting in foreign territories, which would have been subject to materially different approaches to the assessment of FRAND royalty rates and could, therefore, lead to different results (particularly the ongoing litigation between the parties in China and Germany). 
The Court of Appeal explained that in imposing a worldwide licence the High Court did neither adjudicate on issues of infringement or validity concerning any foreign SEPs, nor was it deciding what the appropriate relief for infringement of any foreign SEPs might be (particularly since it made clear that a FRAND licence should not prevent a licensee from challenging the validity or essentiality of any foreign SEPs and should make provision for sales in non-patent countries which do not require a licence)  . 
Moreover, the High Court simply determined the terms of the licence that the Claimant was required to offer to the Defendants pursuant to its FRAND undertaking towards ETSI.  Such an undertaking has international effect.  It applies to all SEPs of the patent holder irrespective of the territory in which they subsist.  This is necessary for two reasons: first, to protect implementers whose equipment may be sold and used in a number of different jurisdictions.  Second, to enable SEP holders to prevent implementers from “free-riding” on their innovations and secure an appropriate reward for carrying out their research and development activities and for engaging with the standardisation process. 
Accordingly, the High Court had not erred in finding that a worldwide licence was FRAND. On the contrary, there may be circumstances in which only a worldwide licence or at least a multi-territorial licence would be FRAND.  German Courts (in Pioneer Acer  and St. Lawrence v Vodafone  ) as well as the European Commission in its Communication dated 29 November 2017  had also adopted a similar approach. 
Having said that, the Court of Appeal recognized that it may be “wholly impractical” for a SEP holder to seek to negotiate a licence for its patents on a country-by-country basis, just as it may be “prohibitively expensive” to seek to enforce its SEPs by litigating in each country in which they subsist.  In addition, if in the FRAND context the implementer could only be required to take country-by-country licences, there would be no prospect of any effective injunctive relief being granted to the SEP holder against it: the implementer could avoid an injunction, if it agreed to pay the royalties in respect of its activities in any particular country, once those activities had been found to infringe.  In this way, the implementer would have an incentive to hold out country-by-country, until it was compelled to pay. 
In its discussion of this topic, the Court of Appeal disagreed with the view taken by the High Court that in every given set of circumstances only one true set of FRAND terms exists. Nevertheless, the court did not consider that the opposite assumption of the High Court had a material effect to the its decision. 
In the eyes of the Court of Appeal, it is “unreal” to suggest that two parties, acting fairly and reasonably, will necessarily arrive at precisely the same set of licence terms as two other parties, also acting fairly and reasonably and faced with the same set of circumstances.  The reality is that a number of sets of terms may all be fair and reasonable in a given set of circumstances.  Whether there is only one true set of FRAND terms or not, is, therefore, more of a “theoretical problem” than a real one.  If the parties cannot reach an agreement, then the court (or arbitral tribunal) which will have to determine the licensing terms will normally declare one set of terms as FRAND. The SEP holder would then have to offer that specific set of terms to the implementer. On the other hand, in case that the court finds that two different sets of terms are FRAND, then the SEP holder will satisfy its FRAND undertaking towards ETSI, if it offers either one of them to the implementer. 
Furthermore, the Court of Appeal dismissed Defendants’ claim that imposing a worldwide licence is contrary to public policy and disproportionate.  In particular, the Defendants argued that this approach encourages over-declaration of patents  and is not compatible with the spirit of the Directive 2004/48/EC on the enforcement of intellectual property rights,  which requires relief for patent infringement to be proportionate. 
Although the Court of Appeal recognised the existence of the practice of over-declaration and acknowledged that it is a problem, it held that this phenomenon cannot justify “condemning” SEP holders with large portfolios to “impossibly expensive” litigation in every territory in respect of which they seek to recover royalties.  The court also found that there was nothing disproportionate about the approach taken by the High Court, since the Defendants had the option to avoid an injunction by taking a licence on the terms which the court had determined. 
The Court of Appeal rejected the Defendants’ argument  that the non-discrimination component of Claimant’s FRAND undertaking towards ETSI obliges the Claimant to offer to the Defendants the same rates as those contained in the licence granted to Samsung. 
The Court of Appeal made clear that the obligation of the SEP holder not to discriminate is, in principle, engaged in the present case, since the Claimant’s transaction with the Defendants is equivalent to the licence it granted to Samsung.  In the court’s eyes, when deciding whether two transactions are equivalent one needs to focus first on the transactions themselves. Insofar, differences in the circumstances in which the transactions were entered into, particularly economic circumstances, such as the parties’ financial position  or market conditions (e.g. cost of raw materials), cannot make two otherwise identical transactions non-equivalent (releasing, therefore, the patent holder from the obligation not to discriminate). Changes in such circumstances could only amount to an objective justification for a difference in treatment. 
Considering the specific content of the SEP holder’s respective obligation, the Court of Appeal agreed with the High Court’s finding that the non-discrimination element of a SEP holder’s FRAND undertaking does not imply a so-called “hard-edged” component (imposing on the patent holder an obligation to offer the same rate to similarly situated implementers).  It argued that the “hard-edged” approach is “excessively strict” and fails to achieve a balance between a fair return to the SEP owner and universal access to the technology.  It could have the effect of compelling the SEP holder to accept a level of compensation for the use of its invention which does not reflect the value of the licensed technology and, therefore, harm the technological development of standards. 
Furthermore, the “hard-edged” discrimination approach should be rejected also because its effects would result in the insertion of the “most favoured licensee” clause in the FRAND undertaking. In the view of the Court of Appeal, the industry would most likely have regarded such a clause as inconsistent with the overall objective of the FRAND undertaking. 
Conversely, the Court of Appeal followed the notion described by the High Court as the “general” non-discrimination approach:  the FRAND undertaking prevents the SEP holder from securing rates higher than a “benchmark” rate which mirrors a fair valuation of its patent(s), but it does not prevent the patent holder from granting licences at lower rates.  For determining the benchmark rate, prior licences granted by the SEP holder to third parties will likely form the “best comparables”. 
The Court of Appeal argued that the “general” approach is in line with the objectives of the FRAND undertaking, since it ensures that the SEP holder is not able to “hold-up” implementation of the standard by demanding more than its patent(s) is worth.  However, the FRAND undertaking does not aim at leveling down the royalty owed to the SEP holder to a point where it no longer represents a fair return for its patent(s), or to removing its discretion to agree royalty rates lower than the benchmark rate, if it chooses to do so. 
In this context, the Court of Appeal made clear that it does not consider differential pricing as per se objectionable, since it can in some circumstances be beneficial to consumer welfare.  The court sees no value in mandating equal pricing for its own sake. On the contrary, once the hold-up effect is dealt with by ensuring that licences are available at the benchmark rate, there is no reason for preventing the SEP holder from charging less than the licence is worth.  Should discrimination appear below the benchmark rate, it should be addressed through the application of competition law; as long as granting licences at rates lower than the benchmark rate causes no competitive harm, there is no reason to assume that the FRAND undertaking constrains the ability of the SEP holder to do so. 
3. Abuse of dominant Position / Huawei v ZTE
The Court of Appeal further rejected Defendants’ argument that, by bringing the infringement proceedings prior to fulfilling the obligations arising from the Huawei judgment, the Claimant abused its dominant market position in violation of Article 102 TFEU. 
To begin with, the Court of Appeal confirmed the finding of the High Court that the Claimant held a dominant market position and dismissed the respective challenge by the latter.  It did not find any flaw in the High Court’s view that the SEP holder has a 100% market share with respect to each SEP (since it is “common ground” that the relevant market for the purpose of assessing dominance in the case of each SEP is the market for the licensing of that SEP  ) and that the constrains imposed upon the SEP holder’s market power by the limitations attached to the FRAND undertaking  and the risk of hold-out that is immanent to the structure of the respective market,  can either alone or together rebut the assumption that it most likely holds market power. 
Notwithstanding the above, the Court of Appeal held that the Claimant had not abused its market power in the present case. 
The court agreed with the finding of the High Court that the Huawei judgment did not lay down “mandatory conditions”, in a sense that that non-compliance will per se render the initiation of infringement proceedings a breach of Article 102 TFEU.  The language used in the Huawei judgment implies that the CJEU intended to create a “safe harbor”: if the SEP holder complies with the respective framework, the commencement of an action will not, in and of itself, amount to an abuse.  If the SEP holder steps outside this framework, the question whether its behaviour has been abusive must be assessed in light of all of the circumstances. 
In the court’s eyes, the only mandatory condition that must be satisfied by the SEP holder before proceedings are commenced, is giving notice to the implementer about the infringing use of its patents.  This follows from the clear language used by the CJEU with respect to this obligation.  The precise content of such notice will depend upon all the circumstances of the particular case.  In general, if an alleged infringer is familiar with the technical details of the products it is dealing and the SEP it may be infringing, but has no intention of taking a licence on FRAND terms, it will not be justified to deny the SEP holder an injunction, simply because it had not made a formal notification prior to the commencement of proceedings. 
On the merits, the court accepted the High Court’s assessment that the Claimant had not behaved abusively and particularly the finding, that the Defendants, who were in contact with the Claimant prior to the proceedings, had sufficient notice that the Claimant held SEPs which ought to be licensed, if found infringed and essential. 
Considering further that the respective conduct requirements were not established at the point in time, in which the infringement action was filed (since the present proceedings were initiated before the CJEU delivered the Huawei judgment), the Court of Appeal noted that it would very likely not be fair to accuse the Claimant of abusive behavior.  Insofar the court agreed with the respective approach developed by German courts in co-called “transitional” cases (Pioneer v Acer,  St. Lawrence v Vodafone  and Sisvel v Haier  )  .
