Ericsson wins SEP infringement case against Lava, awarded Rs. 244.07 crores in damages for patent violations

Delhi HC ruled in favor of Ericsson in a SEP infringement case against Lava. The court found Ericsson owned valid patents, established essentiality and infringement of suit patents, and rejected Lava's invalidity challenges except for one patent (IN 203034). The court determined Lava failed to negotiate in good faith and acted as an unwilling licensee. Damages of Rs. 244.07 crores were awarded based on FRAND rates calculated on entire patent portfolio using net selling price of devices, not chipset value. The court rejected Lava's defenses including doctrine of exhaustion, royalty stacking, and SIPROLAB program relevance.

2. ISSUE-WISE DETAILED ANALYSIS

Ownership of Suit Patents

The plaintiff established ownership by filing certified copies of patent certificates and extracts from the Register of Patents, which were not disputed by the defendant. The Court held that the plaintiff sufficiently proved ownership of all eight suit patents.

Admissibility of Counterclaim

The defendant's counterclaim seeking revocation of the suit patents was held to be admissible under Sections 64 and 104 of the Patents Act. No time limits bar such a counterclaim, and the Court decided in favor of the defendant on this issue.

Permanent Injunction

The plaintiff did not press the issue of permanent injunction as the suit patents expired during the pendency of the suit, rendering the issue infructuous.

Invalidity of Suit Patents

The defendant challenged the validity of the suit patents on multiple grounds:

• Non-patentable Subject Matter (Section 3(k)): The defendant argued that the patents claim mere algorithms, which are excluded from patentability. The Court examined the legal provisions, including Section 3(k) of the Patents Act, and the 2017 Guidelines for Examination of Computer Related Inventions (CRI Guidelines). The Court noted that algorithms per se are not patentable, but inventions incorporating algorithms that produce a technical effect or improve hardware functionality may be patentable.
• Novelty and Inventive Step: The Court applied the 'Seven Stambhas Approach' for novelty assessment and the Windsurfing/Pozzoli tests for inventive step. It reviewed prior art references including ITU-T Recommendation G.729, ETS 300 726, and research papers by Schroeder, Ubale, McElroy, Zinser, and others. The Court held that one patent, IN 203034, lacked novelty and was directed to non-patentable subject matter, thus liable to be revoked. The other seven patents were held valid, novel, and inventive.
• Sufficiency of Disclosure: The Court held that the suit patents sufficiently and fairly describe the invention to enable a person skilled in the art to work the invention, rejecting the defendant's challenge under Sections 64(1)(h) and (i).
• Misrepresentation to Patent Office: The defendant alleged fraud and misrepresentation under Sections 64(1)(j) and (m) and Section 8(1) of the Patents Act. The Court held that such allegations require clear and convincing evidence of deliberate misrepresentation, which the defendant failed to provide, and thus the claim was rejected.

Validity of Individual Patents

The Court conducted detailed claim construction and patentability analysis for each suit patent:

• IN 203034: Found invalid for lack of novelty and being directed to algorithms without patentable hardware.
• IN 203036: Valid patent directed to an apparatus with physical components and technical effect, not merely an algorithm. Novel and inventive over prior art including ETS 300 726 and Schroeder.
• IN 234157: Valid patent involving multiple codebooks and deterministic selection procedure, novel and inventive over prior art including G.729, Ubale, McElroy, ETS 300 726, and Zinser.
• IN 203686: Valid patent concerning alternating transmission of codec mode information, novel and inventive over prior art including Milnor, IEEE 802.11, WO'549, AMR Study Group Report, and others.
• IN 213723: Valid patent on generating comfort noise in speech decoders, with physical apparatus components and technical effect. Novel and inventive over GSM 06.31, GSM 06.12, and ETS 300 971.
• IN 240471: Valid patent on event-based reporting for handover and power control in mobile radio systems. Novel and inventive over Daniel Wong, Blakeney, Srinivasan, and ETSI/3GPP standards.
• IN 229632: Valid patent on multi-service handling by a single mobile station, novel and inventive over Mobiware, Internet RFC 2212, and ETSI Technical Report.
• IN 241747: Valid patent on transceiving unit for block automatic retransmission request with adaptive modulation/FEC coding schemes. Novel and inventive over prior art including EP 0054118, Al-Zoman, Joel Morris, US 5559810, and Kousa.

Declarations Filed Before ETSI

The Court held that the plaintiff's declarations at the project/standard level complied with the ETSI IPR Policy. The timing and details of declarations are contractual matters between the plaintiff and ETSI, and the defendant has no locus to challenge them. The declarations bind the plaintiff to its FRAND commitments.

Essentiality of Suit Patents

The plaintiff proved essentiality through claim charts mapping the patents onto relevant standards, which were not rebutted. The defendant failed to demonstrate any alternate technology or implementation that avoids the plaintiff's patents. The Court held the suit patents essential to the standards.

Doctrine of Exhaustion

The defendant's defense based on the doctrine of exhaustion failed as the defendant did not prove that the chipsets used in its devices were licensed by the plaintiff. The defendant admitted it had no indemnity or license from chipset manufacturers. The Court held that the patents relate to the end-user devices, not just chipsets, and the plaintiff's rights are not exhausted by chipset licenses.

Infringement

Applying the two-step test for SEP infringement, the Court held that the defendant's devices comply with the standards incorporating the suit patents, and therefore infringe the patents. Test reports admitted by the defendant confirmed implementation of AMR and EDGE standards. The defendant failed to prove use of alternate technology or non-infringement.

FRAND Commitment and Licensing Negotiations

The Court explained the FRAND principles as fair, reasonable, and non-discriminatory licensing commitments made by SEP holders to SSOs. The plaintiff's FRAND commitment is contractual and aims to balance patent holder and licensee interests.

The defendant was held to be an unwilling licensee due to its failure to negotiate in good faith, delaying signing of NDAs, refusing to respond to offers, and filing suit just before scheduled negotiations.

Damages and Royalty Calculation

The Court held damages are to be calculated based on royalties payable under a FRAND license. The plaintiff's offers to the defendant were within the FRAND range, supported by comparable licenses with similarly situated Indian companies. The Court rejected the defendant's contentions that damages should be limited to tested devices or calculated on the basis of the smallest saleable patent practicing unit (chipset), holding that the end-product is the appropriate royalty base.

The Court also held that damages should be calculated for the entire portfolio of SEPs, not just the asserted patents, as this aligns with industry practice and ensures interoperability.

The defendant's proposed top-down approach and reliance on SIPROLAB licensing program were rejected as irrelevant and unsupported.

Allegations of Patent Hold-Up and Royalty Stacking

The defendant failed to provide evidence of patent hold-up or royalty stacking. The plaintiff's multiple offers and negotiations over four years without counteroffers negated such claims. The defendant's conduct was characterized as hold-out, delaying licensing and enjoying use of patented technology without payment.

Comparable Licenses

The plaintiff's comparable licenses were held admissible and relevant, involving entities similarly situated to the defendant, supporting the FRAND rates offered.

Offers Made to Defendant

The plaintiff made multiple offers, including in 2013, 2014, 2015, and 2015 (oral), which the defendant did not accept or counter. The offers were consistent with court-approved rates in similar cases.

Limitation Period for Damages

The Court held that damages can be claimed from the date of publication of the patent application, not limited by the three-year limitation under the Limitation Act, as the Patents Act provisions prevail. The defendant was aware of the patents and infringement from November 2011, so damages were awarded from that date.

Calculation of Damages

The Court applied the FRAND royalty rate of 1.05% of the net selling price of devices, adjusted to reflect the invalidation of one patent out of eight. Using sales data provided by the defendant, damages were calculated to be approximately Rs. 244 crores, with interest.

Costs

The Court awarded actual costs to the plaintiff, considering the extensive litigation, conduct of the parties, and the defendant's lack of good faith in negotiations.

Relief

The Court decreed damages in favor of the plaintiff, allowed revocation of the invalid patent, directed issuance of certificates of validity for the remaining patents, and ordered costs.

3. SIGNIFICANT HOLDINGS

"The inventions that are solely directed towards algorithms, mathematical methods, business methods or are computer programmes per se, would not satisfy the test of patentability and would consequently, not be inventions. However, an invention that merely incorporates algorithms, sets of instructions, mathematical or business methods within a method or system, and satisfies all the criteria for patentability, is not inherently non-patentable."

"The 'Seven Stambhas Approach' provides a clear framework for assessing novelty, reflecting the distinction between novelty and non-obviousness."

"The patentability of inventions involving computer programs should be assessed based on the technical advancements and practical application in solving real-world problems, not merely on the presence of algorithms or computer-executable instructions."

"The 'Doctrine of Exhaustion' requires clear and convincing evidence that the product was sold by or with the consent of the patent holder; mere importation from a licensed chipset manufacturer without proof of license extending to end products does not suffice."

"The two-step test for infringement of SEPs involves (i) mapping the patent claims to the standard, and (ii) showing that the implementer's device conforms to the standard."

"FRAND commitments require licensing on terms that are fair, reasonable, and non-discriminatory, balancing the interests of patent holders and implementers, and preventing both patent hold-up and hold-out."

"Damages for infringement of SEPs are to be calculated based on royalties payable under a FRAND license, typically using the net selling price of the end-product as the royalty base, not the smallest saleable patent practicing unit."

"Licensing of the entire portfolio of SEPs is necessary to ensure interoperability and avoid administrative burdens; seeking royalties only for asserted patents is impractical and contrary to industry practice."

"Comparable licensing agreements provide the best evidence of FRAND rates, with the top-down approach serving as a cross-check."

"Patent hold-up and royalty stacking claims require concrete evidence; absent such evidence, allegations are rejected."

"The defendant was an unwilling licensee, having failed to negotiate in good faith, delayed signing NDAs, and filed suit to avoid licensing."

"Damages are payable from the date the defendant was aware of the patent and infringement, not limited by the Limitation Act but governed by the Patents Act."

"The Court awarded damages of Rs. 244,07,63,990/- plus interest, directed issuance of certificates of validity for seven patents, and allowed revocation of one patent."
