Sisvel v Wiko
9 December 2020 - Case No. 6 U 103/19
The claimant, Sisvel, holds patents declared as (potentially) essential to the practice of the UMTS and LTE wireless telecommunications standards, which are subject to a commitment to be made accessible to users on fair, reasonable and non-discriminatory (FRAND) terms and conditions (standard-essential patents or SEPs). Sisvel also administrates a patent pool, comprising patents of several SEP holders, including Sisvel's own SEPs (patent pool).
The defendants are two companies that are part of the Wiko group (Wiko).  Wiko sells mobile phones complying with the LTE standard - among other markets- in Germany.
In June 2015, the patent pool informed Wiko for the first time about the need to obtain a licence. On 1 June 2016, Sisvel (as the patent pool's administrator) offered Wiko a portfolio licence, which also covered the patent in suit. Agreement was, however, not reached.
On 22 June 2016, Sisvel brought an action against Wiko before the District Court (Landgericht) of Mannheim in Germany (District Court) based on one patent reading on the LTE standard (infringement proceedings). Sisvel requested a declaratory judgment confirming Wiko's liability for damages on the merits, as well as information and rendering of accounts.
On 23 June 2016, Sisvel made an offer for a bilateral licence limited to its own SEP portfolio to the German subsidiary of Wiko. This offer was not accepted. Moreover, Wiko filed a nullity action against the SEP in suit before the German Federal Patent Court (nullity proceedings).
In October 2016, Sisvel extended the lawsuit. Claims for injunctive relief as well as the recall and destruction of infringing products were added to the other claims initially asserted.
On 11 November 2016, Wiko made a counteroffer to Sisvel. Some days prior to the oral hearing in the infringement proceedings, Wiko informed the Court that it had provided information to Sisvel and had also deposited a security amount for past uses.
On 8 November 2017, Sisvel made a new offer to Wiko with reduced royalty rates. Wiko did not immediately react to this offer.
On 22 December 2017, Sisvel asked the District Court to order a stay of the infringement proceedings, until the decision of the Federal Patent Court in the parallel nullity proceedings. Wiko agreed with Sisvel's motion. On 30 January 2018, the infringement proceedings were stayed.
On 9 February 2018, Sisvel sent a reminder to Wiko regarding the offer made on 8 November 2017. Wiko responded on 16 February 2018, requesting further claim charts and more time to examine the patents covered by the offer.
On 26 June 2018, during the stay of the infringement proceedings, Sisvel made another licensing offer to Wiko based on a new restructured licensing program (2018 offer). Along with the 2018 offer, Sisvel provided Wiko with claim charts regarding 20 selected patents and a list of existing licensees of both its new licensing program and two pre-existing programs. The list contained the date of the conclusion of each agreement as well as the agreed licence fees. The names of the licensees were, however, redacted.
Wiko did not react to the 2018 offer for more than three months. On 15 October 2018, following a respective reminder sent by Sisvel on 14 September 2018, Wiko replied, without, however, commenting the 2018 offer; it just referred back to its counteroffer dated 11 November 2016. Wiko also criticized the fact that Sisvel did not disclose the names of the existing licensees so far.
In response to that claim, Sisvel shared a draft Non-Disclosure Agreement (NDA) with Wiko on 22 October 2018, based on which it would be willing to disclose the names of the existing licensees. Wiko refused to sign the NDA proposed by Sisvel.
In October 2018, the Federal Patent Court upheld the SEP in suit in part. Subsequently, the District Court moved on with the infringement proceedings. After the end of the oral hearings in July 2019, Wiko made a new counteroffer to Sisvel and provided the latter with additional information. However, Wiko did not increase the amount of security deposited after its first counteroffer dated 11 November 2016.
In the beginning of September 2019, Sisvel set up an electronic data room containing redacted versions of Sisvel's existing licensing agreements with third parties and granted Wiko respective access rights. Wiko did not make use of this data room at any point in time.
On 4 September 2019, the District Court granted an injunction against Wiko and ordered the removal and destruction of infringing products from the market. It also confirmed Wiko's liability for damages on the merits and ordered Wiko to provide Sisvel with information required for the calculation of damages. Wiko appealed the decision of the District Court.
Shortly after the District Court rendered its decision, the term of the patent-in-suit expired. Sisvel, however, enforced the injunction granted by the District Court.
With the present judgment  (cited by http://lrbw.juris.de/cgi-bin/laender_rechtsprechung/list.py?Gericht=bw&GerichtAuswahl=Oberlandesgerichte&Art=en&sid=2b226ea73cc9637362d8e1af04a34d05), the Higher District Court (Oberlandesgericht) of Karlsruhe (Court) predominantly upheld the judgment of the District Court  .
B. Court's reasoning
The Court found that Wiko could not successfully raise a so-called 'FRAND-defence' based on an alleged abuse of market dominance (Article 102 TFEU) against the claims for injunctive relief and the recall and destruction of infringing products asserted by Sisvel. 
This question was still decisive in the present case, despite the fact that the patent-in-suit expired before the start of the appeal proceedings. The Court explained that the expiration of a patent affects only future acts of use (which, then, no longer constitute infringement): On the contrary, claims that had arisen prior to expiration based on acts of use during the lifetime of the patent are not impaired.  Whether claims were given before the expiration of the patent-in-suit is of particular importance, especially when the patent holder has enforced a (first-instance) judgment delivered in proceedings conducted within the term of protection of the patent, as it was the case here. 
Dominant market position
Having said that, the Court agreed with the finding of the District Court that Sisvel had a market dominant position in terms of Article 102 TFEU with respect to the patent-in-suit in the relevant time period prior to its expiration. 
The Court followed the District Court also insofar, as it confirmed that, by filing an infringement action, Sisvel had not abused its market dominance.
Notification of infringement
In the eyes of the Court, Sisvel had sufficiently notified Wiko about the infringement of the patent-in-suit prior to filing a court action.  The purpose of the notification of infringement is to draw the implementer's attention to the infringement and the necessity of taking a license on FRAND terms and conditions.  In terms of content, the notification must identify the patent infringed, the form of infringement and also designate the infringing embodiments.  Detailed technical or legal analysis of the infringement allegation is not required.  The production of so-called 'claim charts', which is common in practice, will, as a rule, suffice, but is not mandatory.  If the patent holder offers a portfolio licence, respective extended information duties occur. 
In the present case, it was not disputed that Sisvel had notified Wiko about the patent-in-suit prior to litigation.  As far as Wiko complained that no claim charts were presented before trial, the Court reiterated that no respective obligation of Sisvel existed.  What is more, the Court held that the court action initially filed by Sisvel, which did not include claims for injunctive relief and the recall and destruction of infringing products, could also be seen as an adequate notification of infringement. 
Willingness to obtain a licence
The Court then found that Wiko behaved as an unwilling (potential) licensee both prior and during the infringement proceedings  . The Court agreed with the assessment of the District Court that Wiko delayed the licensing negotiations between the parties with the goal to avoid taking a licence for as long as possible, in order to gain economic benefits. 
According to the Court, the 'expression of a general willingness to license' is not sufficient for assuming that an implementer is a 'willing licensee'.  Moreover, the implementer must 'clearly and unambiguously' declare willingness to conclude a license agreement on FRAND terms, 'whatever FRAND terms may actually look like"  . The respective declaration must be 'serious and unconditional'. 
The Court highlighted that for the assessment of willingness the overall facts and the particular conduct of the implementer shall be taken into account.  Willingness is not 'static': the finding that an implementer was willing (or unwilling) at a certain moment in time does not remain unchanged henceforth. 
The implementer must always be willing to obtain a licence and participate in negotiations in a 'target-oriented manner'; since implementers might be inclined to delay negotiations until the expiration of the patent-in-suit, there is a need to make sure that their behaviour in negotiations will not lead to delays.  Moreover, it should be expected that a willing implementer would seek a license as soon as possible, in order to shorten the period, in which it makes use of the patent-in-suit or the SEP holder's portfolio without authorisation and without paying licensing fees.  Accordingly, a willing licensee would not consider the 'negotiation obligations' of the SEP holder primarily as a means to defend itself against a court action, but as a means to utilize in order to reach a FRAND agreement, if needed. 
In the view of the Court, the above requirements are in line with the Huawei v ZTE judgment (Huawei judgment or Huawei)  of the Court of Justice of the EU (CJEU).  In Huawei, CJEU focused on the will of the infringer to conclude a license agreement on FRAND terms and emphasized that the latter must not pursue 'delaying tactics'. The Court explained that, although in Huawei the requirement to refrain from 'delaying tactics' is expressly mentioned only with respect to the duty of the implementer to react to a licensing offer of the SEP holder, it applies 'at all times' as long as the implementer uses the patents without a licence; otherwise, the suspension of SEP holder's right to the injunctive relief cannot be justified. 
In this context, the Court pointed out that not every 'reluctant involvement' of the implementer in licensing discussions will necessarily allow for the assumption of unwillingness.  Such behaviour could be justified in individual cases, especially when the SEP holder does not act in a 'target-oriented' manner itself.  Nevertheless, implementers must, as a rule, react timely even to a belated action of the SEP holder.  Furthermore, implementers must, in principle, inform the SEP holder of any objections at an early stage and should not wait to raise those much later in court proceedings. 
Looking at Wiko's conduct, the Court criticized especially the fact that it became active mostly as a reaction to new developments in the pending infringement proceedings.  A willing implementer would have, however, sought a licence independently of the initiation of legal steps and independently of the course of litigation.  As an example, the Court highlighted the fact that Wiko's counteroffer dated 11 November 2016 was made only shortly after Sisvel extended the infringement suit by adding a claim for injunctive relief.  Wiko also provided information on past acts of infringement only a few days prior to the first oral hearing in February 2017 (and refrained from constantly updating this information afterwards, as it would be expected by a willing licensee). 
The Court identified also further facts that indicate that Wiko engaged in delaying tactics.  Wiko reacted to Sisvel's licensing offers made during the course of the proceedings always belatedly and only after a reminder by Sisvel (for instance, it took Wiko more than three months to react to the 2018 offer)  . It also demanded further claim charts in February 2018, years after the action was filed. 
Wiko's refusal to sign the NDA offered by Sisvel -despite multiple reminders of the latter- without providing any reasons was also considered as a sign of unwillingness.  According to the Court, it should be expected by a willing licensee, who is not interested in delaying negotiations, to swiftly raise any criticisms regarding an NDA proposed by the SEP holder in writing or by e-mail, and not wait to raise any concerns several months later in the infringement proceedings, as Wiko had done here.  The Court also considered the fact that Wiko did not access the electronic data room set up by Sisvel containing redacted versions of Sisvel's third party agreements as an additional indication of unwillingness. 
Furthermore, the Court clarified that -contrary to Wiko's view- school holidays and/or staff shortages cannot provide sufficient justification for delays in negotiations.  Even if such circumstances occur, a willing implementer would have communicated any obstacles immediately.  Wiko failed to do so.
SEP holder's offer
Since Wiko was found to have been an unwilling licensee, the Court explained that the question whether Sisvel fulfilled its duty to make and adequately elaborate a FRAND licensing offer, was no longer decisive.  In fact, no such duty had arisen in the present case, due to Wiko's unwillingness to obtain a licence.  Notwithstanding the above, the Court provided guidance on the content and extend of the respective obligation of the SEP holder.
The Court first explained that FRAND is a 'range', which leaves room for flexibility.  As a rule, FRAND is determined in bilateral good faith negotiations between SEP holders and implementers, taking into account the specific circumstances of each individual case  ; indeed, parties are best situated to determine the exact content of FRAND in a specific setting. 
In order to meet its obligation, an SEP holder must present an offer to a willing licensee, which 'in general' complies with FRAND requirements and is fair, reasonable and not discriminatory with respect to the 'average licensee'.  The SEP holder shall further explain its offer in a way that permits the licensee to understand the assumptions, on which the offered rate and further conditions are based.  The rationale behind this obligation is to create a sufficient basis of information for the implementer for assessing the offer and eventually formulating a counteroffer. 
In this context, the Court made clear that implementers should not expect that the SEP holder individually adapts its (first) offer to the specific circumstances of each particular case.  The SEP holder's FRAND commitment does not give rise to such obligation.  The (first) offer is intended to launch the negotiations and provide an adequate information basis to the implementer, who will then be in a position to suggest necessary amendments by means of a counteroffer.  Accordingly, it will regularly be acceptable that the SEP holder's offer is 'not clearly and evidently' non-FRAND and sufficient information was provided to the implementer. 
The Court dismissed the notion that the implementer is obliged to negotiate (and eventually) make a counteroffer, only when the SEP holder's offer was fully FRAND-compliant.  This would bring the negotiations to a stand-still and, therefore, conflict with the spirit of the Huawei judgment, which is to encourage the parties to reach agreement on the licensing terms.  Moreover, the Court explained that –irrespective of whether the offer triggers an obligation of the implementer to submit a counter-offer– the latter will be regularly required, at least, to analyse the SEP holder's offer in due course and express any objections and queries without delay. 
Against this background, the Court found that none of the offers made to Wiko during the infringement proceedings was 'clearly and evidently' non-FRAND.  The fact that the offers did not define the start of the contract or the amount of royalties payable for past uses was not considered problematic.  The Court also found that the royalty rates offered were not 'evidently non-FRAND', since they were sufficiently substantiated by reference to existing licensing agreements and calculated on basis of a 'top-down' method.  A need to calculate royalties on grounds of the costs that incurred for the creation of the patented invention (cost-based approach) was not given, since this factor was not relevant for establishing value. 
In addition, the Court did not raise any concerns against the fact that Sisvel's offer concerned a worldwide portfolio licence: On the one hand, agreements with such scope are common in the telecommunications industry.  On the other hand, Wiko had worldwide activities, so that a licence with a limited scope would not provide sufficient coverage. 
The fact that some of the patents included in Sisvel's portfolio were -allegedly- not standard-essential did not render the offers 'un-FRAND'.  The Court stressed that, for the purpose of licensing negotiations and the conclusion of a licence, it is not necessary to conclusively clarify whether each portfolio patent is standard-essential.  Implementers can reserve the right to challenge the validity and essentiality of affected patents even after the conclusion of a licensing agreement. 
Similarly, the Court had no objections against a clause placing the burden of proof with regard to the exhaustion of licenced patents on Wiko.  This rule corresponds with the common allocation of the burden of proof under German law and does not place unreasonable weight on the licensee, since it will be better situated to trace the licensing chain by engaging with its suppliers. 
The question whether an adjustment clause is necessary for an offer to be considered FRAND was left unanswered by the Court.  Such clause would allow the implementer to adapt the agreed royalties, in case that patents fall out of the scope of the licence (e.g. due to expiration or invalidation). The Court saw no need for a respective contractual provision, since the licences offered by Sisvel would expire and, therefore, be re-negotiated after five years.  The Court did not express any concerns against the term of the offered licence or the termination clauses contained therein, either. 
Furthermore, the Court made clear that Sisvel had adequately elaborated the licensing rates offered to Wiko.  In the infringement proceedings, Sisvel responded to the 'top-down' calculation of Wiko in detail and made relevant clarifications.  According to the Court, Sisvel was under no circumstances obliged to elaborate on a cost-based calculation of royalties, as requested by Wiko; such demand was considered just another means to delay negotiations. 
The Court also found that the counteroffers made by Wiko during the course of the first instance infringement proceedings were not FRAND. 
The Court highlighted that the obligation of the implementer to submit a FRAND counteroffer to the SEP holder is already triggered, when the previous licensing offer of the latter is not 'clearly and evidently' non-FRAND and sufficient information was provided, enabling the implementer to formulate its counteroffer. 
Having said that, the Court took the view that the royalty rates which Wiko offered were very low and, thus, not FRAND-compliant.  The Court criticized especially the fact that the rates were significantly lower than the rates which were considered to be adequate in previous court decisions.  Notwithstanding the above, the Court explained that, even if Wiko's counteroffer had been FRAND, this would not change the conclusion that Wiko had acted as an unwilling licensee.  According to the Court, a willing licensee would not have submitted a counteroffer around one year after receipt of the SEP holder's offer, as Wiko did. 
C. Other important issues
The Court stressed that for generating pressure-free licensing negotiations during pending infringement proceedings, it will, as a rule, be sufficient, if the proceedings are stayed with a view to parallel nullity proceedings concerning the patent-in-suit.  This is particularly true, when the SEP holder takes the respective initiative, as it was the case here.  Nevertheless, even if a pressure-free negotiation situation is not given, the infringers is not released from the obligation to act in good faith and engage in licensing negotiations, for instance by analysing a licensing offer of the SEP holder.  The refusal of the infringer to act accordingly could, in the eyes of the Court, allow the conclusion that it is an unwilling licensee. 
Apart from that, the Court confirmed that Wiko had no legal ground for requesting full disclosure of Sisvel's third party agreements  . Even if one would recognize a duty of the SEP holder to share information about the core content of existing licensing agreements (that are still in force), it is questionable whether this duty would also extend to agreements signed by previous patent holders.  The Court expressed particular doubts that this applies in cases in which a portfolio was assembled from patents acquired from different patent holders, since the relevance of bilateral or pool licensing agreements of the former patent holder can be limited in this case. 
Furthermore, the Court expressed the view that under German law a so-called 'covenant not to sue' does not have the effect of a (royalty-free) licence: such agreements will, as a rule, have only a procedural effect in terms of a pactum de non petendo, excluding only the initiation of court proceedings. 
Finally, the Court denied Wiko's motion to order a stay in the appeal proceedings due to the recent referral of several questions regarding the interpretation of the Huawei framework to the CJEU by the District Court of Düsseldorf in the matter Nokia v Daimler  .  According to the Court, it appears unlikely that the CJEU will establish criteria, by which SEP-based court actions against implementers engaging in delaying tactics would amount to an abuse of market dominance.
