INTRODUCTION

In the world of intellectual property and standards-essential patents (SEPs), few things illustrate the evolving Indian landscape better than the recent decision in the case of Philips v Bathla. This is more than just another patent-infringement fight (in this case, the now-largely defunct VCD format) meets modern legal standards for SEP enforcement, how delays and evidentiary hurdles complicate matters, and what lessons litigants (and the IP ecosystem) should draw. The judgment signals both the promise and the pitfalls of SEP enforcement in India. 

BACKGROUND

STANDARDS-ESSENTIAL PATENTS (SEPS) AND INDIA’S JOURNEY

Standards Essential Patents (SEPs) are patents covering technology that is part of an industry standard (e.g., video formats, telecom protocols). Patent holders usually commit to license SEPs on FRAND (Fair, Reasonable, and Non-Discriminatory) terms. In India, SEP law is relatively new. Early cases like Dolby Laboratories and Ericsson show that Indian courts are increasingly taking SEPs seriously. In Philips v Rajesh Bansal (2018), the Delhi High Court recognized an Indian patent as an SEP and awarded damages. By the time of the Bathla case, some precedent existed, but critical questions remained: how to prove essentiality, how to do claim mapping, and how delays affect remedies.

THE TECHNOLOGY AND PARTIES

The dispute in Bathla involves an older technology: Video Compact Disc (VCD)s, which were popular in Asia in the 1990s for storing and viewing movies on CDs. According to reports, Philips alleged that the defendant (Bathla’s company) used its patented “Digital Transmission System” which was said to cover aspects of audio compression/transmission (linked to the MPEG-1 standard) in the manufacture or replication of VCDs.  The suit patent No. 175971 dated 28 May 1990, is entitled “Digital Transmission System”.  Philips claimed that the defendants’ replication of VCDs (via stampers, molds, etc) used the patented system and furthermore argued the patent was standard essential (i.e., part of a standard) because it overlapped with ISO/IEC 11172-3, an MPEG-1 audio standard. The defendant (M. Bathla & Co) argued:

• They did not manufacture the master discs or encode the audio themselves, but only replicating discs;
• The process used by them did not involve the transmitter/receiver combination claimed in Philips’ patent;
• Philips had not produced independent evidence proving their patent was part of a standard, or that their product used the patented system;
• The master discs (original content) were controlled by film producers, not the defendant. 

PROCEDURAL TIMELINE

• The suit was filed in 2004 (originally CS(OS) 635/2004). 
• The patent expired on 28 May 2010.
• The issues in the suit were narrowed in July 2023 to infringement and damages. 
• Judgment was delivered by the High Court of Delhi on 13 October 2025 (Justice Mini Pushkarna) dismissing Philips’ claim. 

THE CASE: PHILIPS V BATHLA – KEY ISSUES & DECISION

ISSUES FRAMED

Some of the key issues framed or considered by the Court:

1. Whether necessary parties (“film producers”, the technology supplier) should have been impleaded. The Court held in favour of Philips on joinder: the defendants did not justify non-joinder of the parties whose manufacturing/replication chain was in issue. 
2. Whether the suit patent is a system (product) patent or process patent. The Court identified it as a “system patent” (a product patent) under the new CRI Guidelines (Computer Related Inventions Guidelines) 2025 therefore requiring product-vs-claim mapping, not mere end-result. 
3. Whether Philips proved claim-mapping: i.e., did the defendants’ product/process incorporate each element of the claim? The Court found Philips’ claim mapping to be faulty: Philips compared only the end result (e.g., frame length) rather than the claimant’s actual system of transmitter + receiver + wideband digital signal. 
4. Whether Philips’ patent was in fact essential to the standard (i.e., an SEP) and whether sufficient evidence was produced. The Court held that Philips failed to show that the suit patent corresponded to the mandatory part of the ISO/IEC 11172-3 standard; it did not produce an independent expert essentiality certificate, no comparable licenses; the claim mapping to the standard was inadequate. 
5. Whether the defendants’ activity (replication of VCDs) used the patented system (transmission+receiver) or simply a replication of discs via stampers/molds. The Court found that the replication process did not involve the transmitter/receiver transmission system claimed by Philips; therefore, no infringement. 
6. Remedies: although the patent had expired in 2010, Philips sought damages for past infringement. The Court noted the expiration but still considered the period of infringement if proven. 

JUDGMENT AND OUTCOME

The Court dismissed Philips’ suit in full: Philips failed to establish either that the defendants’ replication process used the patented system, or that the suit patent was proved as an SEP. The fundamental mapping requirement (product to the system claim) was unmet; therefore, infringement couldn’t be assumed. In short: no infringement found, no damages awarded. The Court emphasised that the burden of proof rested with Philips (as the patentee) to establish infringement, essentiality, claim mapping and product correspondence and the mere fact of negotiations and correspondence did not change that. 

LESSONS FOR INDIAN SEP LITIGATION

From this case one can draw a number of practical take-aways for litigants, practitioners and policy watchers.

1. Active and timely enforcement matters This litigation dragged for more than 20 years (2004-2025). By the time judgment arrived, the technology (VCD) had effectively become obsolete. That raises the question of value of a win (when the standard itself is defunct). Delay undermines leverage. The judgment itself remarks on the latency.
   Therefore: If you hold an SEP, enforcement needs to be timely; waiting decades reduces commercial relevance.
2. Clear and robust proof of essentiality is critical If a patent is asserted as an SEP, the patentee must show:
   • that the patent is in fact “essential” to a standard (i.e., all or nearly all compliant products must use the patent).
   • supporting documents: declarations to a standards-setting organisation (SSO), essentiality certificates, comparable licences, claim mapping to mandatory standard portions.
     The Bathla case underscores that mere self-serving claim charts won’t suffice: the Court rejected Philips’ claim that its patent corresponded to ISO/IEC 11172-3 because the mapping was flawed and insufficient to show “mandatory” parts.  
3. Claim mapping matters – “system patents” require full mapping The Court held that when the patent is a system or product claim (e.g., a transmitter + receiver + medium), the patentee must show the accused product incorporates each essential element. It is insufficient to show only that the result is similar (e.g., same frame length) or that one component is used. 
4. Replication, outsourcing and manufacturing chains complicate infringement
   Here, the defendant had not built the master disc (where encoding happened) but replicated discs. The Court looked at the actual process: the replication did not include a transmitter/receiver chain, but moulding, metallisation, etc. Hence, no infringement.
   Practically: When suing or defending, map not just the product but the manufacturing/replication chain; know whether the accused uses the patented system or another layer.
5. Prepare for FRAND/SEP nuance even if not explicitly pleaded Although Philips did not frame “essentiality” as a standalone issue initially, the Court nevertheless considered the SEP question and rejected it. For SEP litigation in India: expect SEP-specific issues (essentiality, FRAND, non‐discriminatory licensing) even if not central at the start. Good practice: address them proactively.
6. Obsolescence risk: the “tech life-cycle” question the dispute concerned VCD technology which peaked in the 1990s and effectively died out in the 2000s. By the time of judgment, the commercial relevance was minimal. The judgment notes that “video CDs might be making a comeback” tongue-in-cheek, but the reality is the case’s commercial value was eclipsed. 
7. Evidentiary discipline is essential the court criticized Philips for:
   • Relying on internal documents rather than independent expert essentiality certificates.
   • Not producing comparative licenses.
   • Using correspondence/negotiations (without prejudice) as admissions of infringement. So: build your case with expert reports, independent analysis, before you jump into litigation.
8. Indian SEP jurisprudence is still evolving While some precedents exist (e.g., the 2018 Philips v Rajesh Bansal decision), Indian courts are still refining standards around SEP proof, claim mapping, indirect infringement, etc. The Bathla case adds further colour to that evolution. 

CONCLUSION

The Philips v Bathla case is a fascinating prism through which to view Indian SEP litigation: a decades-old technology, a long-drawn suit, the challenges of proving essentiality and mapping, and finally a dismissal despite the plaintiff being a major SEP holder. The lesson is clear: even if the technology is (market) dead, the legal ecosystem lives on and the quality of preparation, timing and evidence counts enormously. For SEP-holders: don’t assume rights are automatic build your case. For implementers: don’t assume SEPs automatically mean liability challenge mapping and essentiality. As India’s SEP jurisprudence matures, this case provides a cautionary tale and a roadmap “Long live the tech” indeed (even if the tech itself is gone).
