Introduction
A significant ruling in Indian patent law specifically regarding Standard Essential Patents (SEPs) and intellectual property enforcement was rendered in the Koninklijke Philips Electronics N.V. v. Maj. (Retd.) Sukesh Behl & Anr. case. These ruling settles three related lawsuits brought by Philips-the plaintiff regarding the infringement of Indian Patent No. 218255 which deals with a “Method of Converting Information Words to a Modulated Signal.” The Delhi High Courts’ ruling on 20 February 2025 thoroughly reviewed the allegations of patent infringement, counterclaims of invalidity and licensees’ wider responsibilities under the Patents Act 1970. The Court’s conclusions the application of Indian patent law and the ramifications for upcoming intellectual property conflicts are the main topics of this article’s thorough legal examination of the case.
Legal Issues the Court Took into consideration.
The Court was forced to address several significant legal issues:
- Whether the Plaintiff had the right authorisation to bring the case.
- Should the patent have conformity to Patents Act 1970 and have been valid.
- In case the Defendants had infringed the Patent in Suit.
- In case the Defendants were unwilling licensees.
- Whether the Plaintiff could have claimed the compensation and other reliefs or not.
They have discussed each of these questions specifically with references to legal precedents, legislations and provided evidence provided by both parties.
Maintainability of the Suit: The Question of Authorisation.
The defendants first threw preliminary objections at the plaintiff, disputing the plaintiffs right to file the suit and the validity of the claim. They claimed the person who sued did not have the proper permission. They asked if Mr. Farukh N. Bhiwandiwala, who signed the pleadings for Philips was really allowed, they say that he was not a director of One Red LLC, a related entity. When cross-examined, Mr. Bhiwandiwala admitted he had not looked at a board resolution authorizing Mr. E. P. Coutinho to start the action, but was just trusting on the general powers under Dutch law. The plaintiff replied by showing a power of attorney and Dutch Trade Register records which confirmed Coutinho’s authority.
Validity 114 of the Suit Patent: Revocation Claims.
The defendants challenged the validity of the suit patent under several provisions of the Patents Act 1970 which comprises thirteen claims. Claims 1–11 and 13 concern a process of converting m‑bit information words into a modulated signal each information word being mapped to an n‑bit code word with n>m such that the resulting code words when processed under specified conversion rules satisfy a predetermined condition and yield the desired modulated signal. This method underpins Eight‑to‑Fourteen Modulation Plus (EFM+) coding used in next‑generation DVDs where 8‑bit information words are encoded as 16‑bit code words to enable an efficient system of information transfer, and the patent also extends to recording, storage, transmission, and decoding of such information. Claim 12 being at the heart of the dispute is about the record carrier having in a track a modulated signal generated by the method of claims 1-11.
On the procedural issue the Court was of the opinion that objections to authorization are only procedural issues and that they cannot be allowed to be a bar to substantive patent rights unless the defect is so fundamental that it completely deprives the Court of jurisdiction. The Court further pointed out that the defendants had failed to come up with any evidence to the effect that Mr. Bhiwandiwala did not have the authority to act on behalf of the company. It further pointed out that, according to Order XXIX Rule-1 CPC, a company may be plaintiff or defendant in its own name through the secretary, director or officer who is the most competent as to the facts and who has been so authorized either by the board of directors or a fortiori by the general meeting.
Philips’ continuous participation in the litigation, payment of court fees, attendance at hearings and acknowledgment of the acts of Mr. Bhiwandiwala, taken together, were not only a token of the implied corporate ratification but also confirmation of his authority and the furtherance of the proceedings.
Their main assertions were founded on the following points:
Noncompliance with Section 8
Section 64(1)(m) of the Patents Act 1970 states that a patent may be revoked for not furnishing or furnishing incorrect information required under Section 8. The defendants alleged that the plaintiff had intentionally not disclosed foreign patent applications to the Indian Patent Office. The Court held that such errors in disclosure while they could have been avoided did not amount to deliberate concealment in the absence of any evidence that the prosecution counsel was aware of the error or had the intention to deceive. Most importantly the defendants were unable to demonstrate that the omission of the information had any significant impact on the granting of the patent especially since the foreign filing was still valid and enforceable at the time of grant. The plaintiff produced evidence that the disclosures were made on the basis of the best available internal records at the time of filing and pointed to the ever-changing nature of global patent portfolios. Simple clerical errors or unintentional omissions without any evil intent cannot be the cause of revocation.
Lack of Novelty and Lack of Inventive Step (Section 64(1)(e))
The defendants relied on Section 64(1)(e) of the Patents Act 1970 to say that the patent in suit is not new and that the invention is obvious because there was already a Sony patent for the same invention. The plaintiff replied that its EFM+ modulation technology was a step forward from Sony’s simple 8 to 16-bit conversion as it used a set of rules in the encoding process to allow the decoder to identify the information word uniquely something that was not present in the prior art. The plaintiff’s expert indicated the different conversion method in the suit patent.
The Court refused the motion and ruled that in order for a prior art to anticipate it must contain all the elements of the invention as claimed arranged and functioning in the same way, mere similarities are not enough. The Court went on to say that the patent in suit had the novelty of enabling the DVD standard and defeating the prior art limitations, the defendants were not able to show that the prior art had the same structure, function or effect as the invention.
Alleged Privy clause Fraud and Misrepresentation (Section 64(1)(j))
The defendants claimed that Philips obtained the patent by fraudulent misrepresentation and concealment of material facts. The defendants asserted among other things that the suit patent was first submitted as a divisional application of the original application number 136/CAL/1995. Four years later the divisional application was submitted to the Patent Office’s Chennai branch rather than its Kolkata branch. The original and divisional applications were intended to be submitted to the same Patent Office branch. Additionally, it was noted that the divisional application does not contain any additional claims which is a prerequisite for filing a divisional patent under Section 16 of the Patent Act and that the divisional application and the original application are equivalent. These disparities suggest that the filing process may have been compromised and that facts may have been misrepresented or concealed. These details will be considered as proof that the plaintiff disregarded the rules regulating divisional applications.
The Court rejected this argument as well for the reasons set out below:
The Court decided that fraud allegations in Section 64(1)(j) require the defendant to prove that the plaintiff knowingly misled or concealed the truth. The defendants have not been able to prove their case even after producing a lot of evidence. The decision as to which office a patent application should be filed in according to Rule 4 of the 1972 Patent Rules is based on the applicant’s address for service. Hence, the first application which had a Kolkata lawyer was filed there and the divisional application which had a representative from Chennai was filed in Chennai because no rule at that time forced the same office. The original application’s automatic termination upon the filing of the divisional did not entail any additional disclosure requirement. The plaintiff fulfilled his obligation by revealing the original application in Form 1 with no duty to explain abandonment.
The Court confirmed that the Court meeting the divisional under Section 16 was reasonable due to distinct inventive concepts and therefore, the claim of double patenting was denied. As such, the disclosures were consistent with the statutory framework, and the invalidity grounds were rejected.
Insufficiency of Disclosure (Section 64(1)(h))
The Court dismissed the insufficiency of disclosure claims under Section 10(4) as the specification disclosed the invention quite thoroughly first describing the EFM+ encoding in detail then the modulation steps, the record carrier structure and the method of producing the best product. This was all supported by the unchallenged expert cross-examination. The present Sections 3(k) and 3(m) allegations unanimously put down by the Court, rest on a misconception of the facts. The word to code conversion algorithm that defines the modulation is in fact a hardware implemented operation in the storage device that brings about a substantial technological advancement thus going beyond the mere software or schemes level of inventions. Speaking of essentiality, the Court considered the patent as one of the foundations of the DVD standards. The unchallenged claim mapping along with the expert testimony has demonstrated that the compliant implementations must infringe the defendants have failed to put forward any alternative non-infringing ones. Thus, direct infringement was unequivocally established including through the use of pre-encoded stampers.
Patent Infringement: Were Philips’ Rights Violated by Defendants?
Understanding the Infringement Claims
The main point of prosecution was that the Defendants, a DVD replication business were unlawfully utilizing Philips’ patented EFM+ technology. Philips claimed that EFM+ was the core technology of DVD replication and a manufacturer who made DVDs according to the set standards would be the one using the patented method.
Defendants’ Counter-Argument: Outsourcing and Licensing Issues
Defendants refuted the charges of infringement by stating that they were merely performing DVD replication using the already encoded stampers obtained from the third-party vendors. They argued that as they were not the ones directly carrying out the encoding process, they should not be held responsible.
Court’s Findings on Infringement
The Court dismissed the defendants defence and stated that Claim 12 of the suit patent covers any record carrier bearing an EFM+ modulated signal, irrespective of the production method (e.g., laser burning), as the specification distinguishes between process and product. The broad scope here covered the defendants’ replica DVDs made by the pre-encoded stamper method which inherently contained the patented signal and thus constituted direct infringement.
Section 48 of the Patents Act 1970 grants a patentee the right to prevent the use of a patented process or the sale of products made therefrom by third parties without his consent. The defendants’ DVD standard, compliant products thus violated the SEP and they failed to show a feasible non-infringing alternative.
The Concept of FRAND Obligations and Unwilling Licensees:
The Court held that Philips, being the owner of SEPs had through its utmost diligence made FRAND licensing offers as shown by the correspondence seeking a “Philips-only” license or a joint licensing of Sony, Pioneer, and LG patents along with details of royalties and DVD license agreements. This was clear evidence of the willingness to grant non, discriminatory licenses. Defendants who had no dispute about receiving these letters refused to sign, thus proving that Philips was a party that complied with its FRAND obligations while they were acting as unwilling licensees.
The Court believed:
The Defendants knew that the license was required but decided to go on without it. The Defendants’ rejection of the offer to take a license is a clear indication of their lack of good faith and non-observance of FRAND principles. Moreover, their characterization as “unwilling licensees” helped to consolidate the case of infringement of which they should pay damages.
Relief Granted: Injunctions, Damages and Legal Costs
The Court based on its evidence granted several reliefs to Philips.
Permanent Injunction: The defendants were prohibited from the manufacture, sale or distribution of DVDs utilizing the patented technology without a license properly obtained.
Monetary Damages: The defendants were ordered to make good on the losses suffered by Philips due to the infringement. The calculation of the sum of money was done based on production and sales data that were presented as evidence.
Litigation Costs: The defendants were instructed to pay the entire legal expenses that the plaintiff had met.
Patent Validity Maintained: The registry was directed to uphold the patent and reject all claims for revocation.
Conclusion: A Strong Precedent for Patent Enforcement in India
This decision significantly impacts patent enforcement in India, particularly with respect to standard essential patents. The decision negates the right of businesses to operate without a license presupposing that businesses have complied with such licenses and sets a clear precedent for accountability of unwilling licensees in cases where they are held liable. By upholding the patent and awarding a substantial sum as damages, the Court sent a powerful signal about the role of intellectual property as a tool for innovation and a shield for patent owners against unauthorized exploitation.
