Bansal v. Koninklijke Philips: the first Division Bench reversal of a post-trial SEP infringement decree and what it does to the FRAND-evidence architecture

Bansal v. Koninklijke Philips Electronics NV is, on the publicly available reporting, the first Division Bench reversal of a post-trial Standard-Essential Patent ("SEP") infringement decree in India. The single-judge decree under appeal was passed by Manmohan, J., on 12 July 2018 in suits brought by Koninklijke Philips Electronics NV against multiple Indian DVD-component importers and assemblers (including the Bansal group of defendants) for infringement of Indian Patent IN 184753 ("IN '753") — a Philips-owned patent that Philips alleged was essential to the DVD video-decoding standard built on MPEG-2 technology. The decree carried damages, an injunction and an accounts inquiry. The appellants — Bansal and the other co-defendants — filed RFA(OS) (Comm) 17/2018 and connected appeals.

On 18 May 2026, a Division Bench of the Delhi High Court (C. Hari Shankar, J. and Om Prakash Shukla, J.) allowed the appeals, set aside the 2018 decree, and produced the most consequential intervention on Indian SEP doctrine since Intex Technologies (India) Ltd v. Telefonaktiebolaget LM Ericsson, 2023:DHC:2243-DB, of Manmohan, J. (then sitting in a Division Bench with Saurabh Banerjee, J.) had established India's first authoritative DB FRAND framework. Intex v. Ericsson had set the structural architecture — willing-licensee test, comparable-licence pricing, pro-tem deposit. Bansal v. Philips now sets the evidentiary architecture — what the SEP holder must prove, how, and through which witnesses, before any of the Intex structural protections engage.

The factual matrix and the Single Judge decree

The dispute had its origins in the late-1990s build-out of the global DVD architecture. Philips, along with Sony and other founding members, had developed and licensed a substantial portfolio of patents covering the MPEG-2 video-decoding architecture on which DVD playback depends. IN '753 — granted in India in 2000 — was one of the patents in that family, claiming techniques related to MPEG-2 decoding. Philips operated a DVD-related licensing programme through which DVD-player manufacturers and component suppliers worldwide took licences on standardised rate-card terms.

The Indian dispute arose because the Bansal group and the other defendants imported DVD-related components into India and assembled them into finished DVD players for the domestic market. Philips' position was that the components — manufactured in China — embodied techniques claimed in IN '753 and that any DVD-compliant component necessarily practised the patent. The defendants' position was that they had purchased the components from Chinese suppliers in arm's-length transactions, that the components were lawful in their country of manufacture, and that the patent was in any event invalid and not infringed.

Manmohan, J., in the 12 July 2018 judgment, found in Philips' favour. The single-judge reasoning rested on three propositions. The first was the "infringement by standard-compliance" proposition — that because the DVD specification could not be implemented without practising the techniques claimed in IN '753, any DVD-compliant component necessarily infringed. The second was that Philips' essentiality certificates — issued by a panel of consultants Philips had retained for the purpose — were sufficient evidence of essentiality. The third was that Philips' published rate-card formula constituted a fair, reasonable and non-discriminatory ("FRAND") rate that the defendants were obliged to pay even where they had not negotiated for a licence. The decree carried damages computed on the rate-card formula applied to the defendants' import volumes, plus injunction and accounts inquiry.

The Division Bench's four doctrinal moves

The DB reversed on each of the central propositions of the single-judge decree.

Essentiality is a fact requiring proof. The DB's first move — and the doctrinal centre of the judgment — was to hold that essentiality of a patent to a technical standard is a fact. It is not, despite the SEP-licensing industry's working assumption, a self-proving feature of the patent text. The patent's claims must be mapped onto the standard, claim by claim, in a document — a "claim chart" — that demonstrates the correspondence at the level of textual and technical specificity. The mapping must be supported by witnesses who can be cross-examined on the basis of their expertise, the rigour of their analysis, and the soundness of their methodology.

Philips, on the DB's reading of the trial record, had not done this. The essentiality certificates that Philips had tendered were unsupported by an annexed claim chart that mapped the suit-patent claims to the relevant clauses of the MPEG-2 specification. The authors of the certificates — the consultants Philips had retained — were neither produced at trial nor offered for cross-examination. The certificates were, in evidentiary terms, the equivalent of an opinion offered without the basis of the opinion being placed before the court and without the author being available to be tested on that basis under Sections 45 and 47 of the Indian Evidence Act 1872.

Without proof of essentiality, the "infringement by standard-compliance" theory collapsed. The theory presupposes that the patent is in fact essential to the standard. If essentiality is not proven, the theory cannot supply the necessary link between standard-compliance (which the defendants did not contest) and infringement of the suit-patent (which the defendants had specifically contested). The single-judge decree had treated the essentiality certificates as a sufficient link; the DB held that they were not.

Patent exhaustion under Section 107A(b). The DB's second move was the first DB application of Section 107A(b) of the Patents Act 1970 to an SEP infringement claim. Section 107A(b) — sometimes referred to as the "Bolar"-style provision but, in its second limb, an international-exhaustion provision — states that the importation of patented products by any person from a person duly authorised under the law to produce, sell or distribute the product does not constitute infringement.

The DB held that the DVD components in suit had been manufactured in China by parties holding Philips-issued licences under the relevant national IP regimes. They had been put on the market in China by Philips' authorised licensees, and the Indian defendants had purchased them at arm's length from those licensees or their downstream distributors. The components had, in Section 107A(b) terms, been placed on the market by persons duly authorised. The patentee's rights were exhausted as against the Indian importers and downstream sellers — a separate and independent ground on which the suit-against-importers theory could not stand.

The exhaustion finding has industry-wide implications. The Indian SEP-licensing model has, to date, treated SEP-bearing components manufactured abroad under Philips/Nokia/Ericsson/Dolby licences as nonetheless infringing when imported into India unless a separate Indian licence is taken. The DB's reading of Section 107A(b) — at least on the Bansal v. Philips facts and to the extent the facts can be generalised — closes that double-licensing window where the foreign manufacturer is itself a Philips/Nokia/Ericsson licensee.

The FRAND-rate burden and comparable-licence evidence. The DB's third move addressed the rate-side of the FRAND inquiry. The single-judge decree had treated Philips' published rate-card formula as itself constituting FRAND-compliant. The DB held that this was insufficient: the burden of proving that a rate is FRAND-compliant is on the SEP holder, and the discharge of that burden requires comparable-licence evidence. The SEP holder must produce, or substantively account for the absence of, licences it has executed with similarly situated licensees on terms that the SEP holder asserts are FRAND-compliant. The trial court can then assess whether the rate demanded against the present defendant is consistent with the rate at which the SEP holder has actually licensed.

On the Philips record before the DB, the comparable-licence evidence had not been put forward. Philips had asserted that its rate-card formula was FRAND but had not tendered the executed licences that would have allowed the trial court to verify the assertion. The DB held that the per-device rate-card formula could not, without comparable-licence evidence, substitute for proof that the defendants had actually used the patented techniques in quantities matching the formula's application. The rate-card formula was treated as Philips' opening position in a negotiation, not as a judicially-cognisable measure of FRAND value.

The 2023 Intex framework, applied for the first time at the post-trial stage. The DB's fourth move was to apply the structural framework of Intex v. Ericsson — the DB ruling of March 2023 in which Manmohan, J. and Saurabh Banerjee, J. had set out India's first authoritative SEP/FRAND architecture — at the post-trial stage for the first time. Intex had operated on the interim-injunction-and-pro-tem-deposit plane: the SEP holder, having shown a prima facie case of essentiality and infringement, was entitled to interim relief subject to a security deposit, and the implementer had to engage as a willing licensee with the negotiation rather than holding out. The DB in Bansal v. Philips took the Intex architecture as the framework against which the trial record must be assessed. The prima facie standard that Intex had articulated at the interim stage maps onto a balance-of-probabilities standard at trial, and Intex's structural commitments — to claim-charts, to comparable licences, to willing-licensee conduct on both sides — translate into proof requirements at trial. Bansal v. Philips is the first occasion on which a DB has held an SEP holder's trial record against that translated standard and found it wanting.

The reasoning that runs through

Three doctrinal threads weave through the judgment.

The first is the fact-versus-assumption discipline. Indian SEP enforcement has, to date, operated to a substantial extent on assumptions — that the rate-card is FRAND, that the essentiality certificate is sufficient, that standard-compliance equals infringement. The DB's framework converts each of these assumptions into a fact to be proved. The conversion is itself the judgment's most consequential doctrinal move. It puts the SEP holder on notice that the working assumptions of the licensing industry are not, at trial, a substitute for evidence.

The second is the evidentiary discipline of cross-examination. Essentiality certificates, rate-card formulae and comparable-licence summaries are all the SEP holder's own statements about facts the SEP holder is asserting. The Indian Evidence Act — and ordinary trial discipline — require that statements of that kind be supported by witnesses available for cross-examination. The DB's repeated emphasis on the absence of the certificate authors from the witness stand reflects this discipline. The SEP holder cannot, in a contested infringement trial, rely on its own internal valuation work to establish FRAND-rate compliance any more than a damages claimant can rely on its own internal valuation work to establish quantum.

The third is the integration of patent exhaustion into the SEP-licensing model. The DB's reading of Section 107A(b) is not new as a textual matter — the provision has been on the statute book since 2002 — but its application to SEP enforcement against importers and downstream sellers is. The reading aligns Indian patent law with the international-exhaustion architecture that several jurisdictions have adopted, and it does so through a provision that the legislature has put on the books for that purpose.

The doctrinal contribution

Bansal v. Philips is, in operational terms, a reset of the Indian SEP-evidence architecture. The structural FRAND framework — willing licensee, comparable licences, pro-tem deposit — was articulated by Intex v. Ericsson in 2023. The evidentiary architecture — what the SEP holder must prove and how — is articulated by Bansal v. Philips in 2026. The two judgments together supply the doctrinal scaffolding within which the ongoing Ericsson, Nokia, Dolby and Malikie matters will now be litigated.

The judgment has immediate implications for the Malikie Innovations v. Xiaomi Corporation line at the Delhi High Court, where Malikie has obtained substantial pro-tem deposit orders against Xiaomi. The pro-tem deposit at the interim stage was secured on the Intex framework's prima facie showing; the question whether the same record will hold up at trial against the Bansal v. Philips essentiality, exhaustion and comparable-licence standards is now a live one. The Bansal v. Philips essentiality standard maps directly onto the question of whether Malikie can produce, at trial, the claim-charts and witness testimony that would support its essentiality assertions; the exhaustion question maps onto the position of the Xiaomi components imported from authorised manufacturers; and the FRAND-rate question maps onto the comparable-licence evidence that Malikie has been asked to produce in the interlocutory exchanges.

It has parallel implications for the Nokia v. Oppo line, where similar pro-tem deposit orders have been made on the Intex framework, and for the Ericsson v. Lava International line, in which Justice Amit Bansal delivered a post-trial SEP merits decision in March 2024 on a record that — under the Bansal v. Philips standard — will now be open to appellate reassessment.

The judgment is also doctrinally significant for the broader patent-litigation architecture. The fact-discipline that the DB has imposed on the essentiality inquiry is, structurally, the discipline that F. Hoffmann-La Roche Ltd v. Cipla Ltd, 2015 SCC OnLine Del 13619, had imposed on the claim-construction inquiry in the pharma context: the patent and its claims must be examined in their own terms, on the trial record, by witnesses subject to cross-examination, without resort to working assumptions that the patentee carries into the litigation from its commercial practice. The doctrinal lineage runs from Roche v. Cipla through Intex v. Ericsson to Bansal v. Philips; each judgment ratchets up the evidentiary discipline at a structurally different point in the patent-enforcement chain.

What the Court did not decide

The DB's judgment, on the publicly available reporting, leaves several questions open or addresses them only obliquely.

The scope of the international-exhaustion holding beyond the Philips facts. Section 107A(b) operates on the predicate of "a person duly authorised under the law" — the foreign manufacturer of the patented component. Whether the predicate is satisfied is a fact-specific question that will turn, in each subsequent matter, on the licensing chain in the relevant jurisdiction. The DB has applied the provision to the Philips/China facts; the wider reach across other licensing patterns and other source jurisdictions will be worked out case by case.

The interaction with the 2021 SEP-policy discussions at the Department for Promotion of Industry and Internal Trade — the question whether the judicial baseline obviates the need for a statutory FRAND-determination framework, or instead supports the case for one, is a policy debate that the judgment leaves open.

The damages-quantification framework in a future SEP case where essentiality, infringement, exhaustion and FRAND-rate are all proved. The DB's reasoning is, in substance, a reversal of a decree on absence of proof; it does not articulate, in a case where proof is established, how damages should be computed. The Communication Components Antenna Inc. v. Rosenberger Hochfrequenztechnik matter (2026 SCC OnLine Del 1357) — in which Pratibha M. Singh, J., awarded approximately ₹152 crores in damages — supplies a non-SEP comparator in the same court for the same period; the doctrinal mapping from the non-SEP damages model onto an SEP damages model post-Bansal v. Philips remains to be worked out.

The availability of injunctive relief in SEP cases post-Bansal v. Philips. The DB has set aside both the damages and the injunction; the judgment does not foreclose injunctive relief in a future SEP case where the essentiality, infringement and FRAND-rate elements are proven, but its emphasis on the SEP holder's evidentiary discipline implies that injunctive relief, like damages, will require the same evidentiary foundation.

The practitioner's take

For the SEP holder. The post-Bansal v. Philips trial preparation is materially more demanding. Essentiality must be supported by a claim-chart that maps each asserted claim to the relevant clause of the standard, prepared by an expert who can be produced and cross-examined. The FRAND-rate must be supported by executed comparable licences or by a substantive account of why such licences are not available; rate-card formulae will not, by themselves, suffice. The exhaustion architecture must be addressed head-on: where the implementer's components originate from a licensed manufacturer, the SEP holder must be prepared to address the Section 107A(b) defence on the facts.

For the implementer. The judgment supplies four affirmative defences that should be developed at the pleadings stage. Non-essentiality — supported by a counter-claim chart that contests the SEP holder's mapping. Patent invalidity — supported by the conventional Section 64 grounds. Exhaustion under Section 107A(b) — supported by evidence of the licensing chain in the source country. Failure of FRAND proof — supported by demands for production of the SEP holder's comparable licences. The four defences operate independently; success on any one of them is sufficient to defeat the infringement decree.

For the FRAND negotiator. The Intex willing-licensee framework continues to discipline negotiation conduct on both sides. Bansal v. Philips tilts the negotiation balance — at the margin — towards the implementer, by raising the evidentiary cost of litigation for the SEP holder. Licensing programmes that have, to date, operated on rate-card and essentiality-certificate working assumptions may find themselves under pressure to renegotiate on the Bansal v. Philips evidentiary baseline.

For the trial judge and the drafter of prayer clauses. The judgment supplies a structured analytical framework for SEP infringement trials: essentiality first, infringement second, exhaustion third, FRAND-rate fourth, damages last. Each element must be supported by evidence on the record. Prayer clauses that seek damages computed on a rate-card formula or injunctions on essentiality-certificate proof alone should be supplemented with prayers that anticipate the Bansal v. Philips evidentiary requirements — comparable licences on the record, claim-chart witnesses available for cross-examination, and the exhaustion architecture addressed on the implementer's actual supply chain.
