Supreme Court of India | Civil Appeal No. 6718 of 2013 | Decided: 2 June 2014 Bench: Justice Jagdish Singh Khehar & Justice A.K. Patnaik Citation: AIR 2014 SC 2210 | (2014) 15 SCC 360
Background
Dr. Aloys Wobben, a German scientist-engineer and one of the world’s largest manufacturers of wind turbines, held approximately 2,700 patents across 60+ countries, including around 100 patents in India. His manufacturing operations were conducted through Enercon GmbH. In 1994, he entered into a joint venture with Yogesh Mehra and Ajay Mehra to form Enercon India Limited, through which his patented technology was licensed for use in India under a series of intellectual property licence agreements. The last such agreement, executed on 29 September 2006, was terminated by Enercon GmbH on 8 December 2008 citing non-fulfillment of obligations.
Despite termination, Enercon India Limited continued using Dr. Wobben’s patents without authorisation. In January 2009, Enercon India Limited filed 19 revocation petitions before the Intellectual Property Appellate Board (IPAB) seeking revocation of Dr. Wobben’s patents. In response, Dr. Wobben filed 10 patent infringement suits before the Delhi High Court. The respondents then filed counter-claims in those infringement suits also seeking revocation of the same patents, while simultaneously continuing to pursue revocation petitions before the IPAB. Subsequently, 4 more revocation petitions were filed before the IPAB in 2010–2011, bringing the total to 23. This created a situation where the same patents were being challenged simultaneously before two different forums – the IPAB (through revocation petitions) and the Delhi High Court (through counter-claims).
Issues for Determination
The Supreme Court was called upon to determine the following core questions:
- Whether a party can simultaneously pursue both a revocation petition before the IPAB and a counter-claim for revocation before the High Court in respect of the same patent under Section 64(1) of the Patents Act, 1970.
- Whether the filing of a counter-claim for revocation in an infringement suit before the High Court ousts or suspends the jurisdiction of the IPAB over a pending revocation petition and vice versa.
- Which of the two remedies must prevail when both have been invoked – and on what principle should that determination be made?
- Whether the consent order passed by the Delhi High Court on 1 September 2010 consolidating all suits and counter-claims for trial before it was legally valid and binding.
Key Holdings of the Court
The Supreme Court laid down the following holdings:
First, Section 64(1) of the Patents Act provides three routes to challenge a patent – by any person interested before the IPAB, by the Central Government before the IPAB and by a defendant through a counter-claim in an infringement suit before the High Court. These are distinct remedies vested in distinct parties before distinct forums.
Second, the word “or” in Section 64(1) is disjunctive and not conjunctive. A party is entitled to invoke only one of the available remedies and cannot pursue both a revocation petition and a counter-claim simultaneously for the same purpose against the same patent.
Third, the remedy that survives depends on the chronological order of institution. Where a revocation petition was filed before the institution of the infringement suit, the revocation petition must be allowed to continue and the counter-claim must be stopped. Where the infringement suit was filed first and the counter-claim followed, the counter-claim prevails and any subsequently filed revocation petition before the IPAB must be held unsustainable.
Fourth, proceedings under Section 25(2) of the Patents Act (post-grant opposition before the Controller) eclipse all rights of the same person under Section 64(1), including both the right to file a revocation petition and the right to file a counter-claim.
Fifth, the consent order dated 1 September 2010, passed by the Delhi High Court consolidating all suits and counter-claims for a joint trial, was fully valid and legally justified. Having consented to resolution before a single forum, neither party could seek redressal from an additional forum.
Statutory Provisions Involved
Section 64(1), Patents Act, 1970 – The central provision governing revocation of patents, providing three modes of challenge (revocation petition by a person interested, petition by the Central Government and counter-claim in an infringement suit), prefaced by the words “Subject to the provisions contained in this Act.”
Section 25(1) and Section 25(2), Patents Act, 1970 – Governing pre-grant and post-grant opposition to patents respectively; Section 25(2) allows a person interested to oppose the grant within one year of its publication before the Controller.
Section 2(1)(t), Patents Act, 1970 – Defines “person interested” as one engaged in or promoting research in the same field as the invention.
Section 104, Patents Act, 1970 – Deals with jurisdiction of courts in patent matters and provides that counter-claims for revocation in infringement suits are to be adjudicated by the High Court.
Section 10, Code of Civil Procedure, 1908 – Stay of suit, applied by the Court by analogy to prevent parallel proceedings on the same cause of action between the same parties.
Section 151, Code of Civil Procedure, 1908 – Inherent powers of the Court to prevent abuse of process, relied upon to support the principle against simultaneous parallel proceedings.
Section 124, Trade Marks Act, 1999 – Referred to by the appellants by way of analogy, to highlight that the Trade Marks Act expressly provides for staying infringement suits pending rectification proceedings, arguing that a similar legislative gap existed in the Patents Act.
Reasoning of the Court
The Court approached the matter through a combination of textual, purposive and principled reasoning.
On the question of construction of Section 64(1), the Court placed significant emphasis on its opening words – “Subject to the provisions contained in this Act.” The Court held that this prefatory language renders Section 64 subordinate and deferential to every other provision of the Patents Act. This meant that Section 64 could not be interpreted in a manner that conflicts with any other provision of the Act, including Section 25. Where Section 25(2) proceedings had already been initiated by a party, those proceedings would eclipse any rights available to the same party under Section 64(1).
On the disjunctive nature of the remedies, the Court interpreted the word “or” in Section 64(1) as clearly separating two alternative and mutually exclusive remedies. Permitting simultaneous pursuit of both remedies would risk contradictory findings on the validity of the same patent – one by the IPAB and another by the High Court – which would be legally untenable and an abuse of the judicial process.
To determine which remedy prevails when both have been wrongly invoked, the Court applied the principle underlying Section 10 CPC – that a subsequently instituted proceeding on the same cause of action between the same parties cannot be permitted to continue when an earlier proceeding is already pending before a competent forum. Treating a counter-claim as equivalent in nature to an independent suit (since it is tried as a plaint and has the effect of a cross-suit), the Court held that the first-in-time proceeding must prevail and the later one must yield.
On the consent order, the Court held that procedural rules are the “handmaids of justice.” Since the dispute, though involving different patents, was of the same nature and between the same parties, it was entirely appropriate – indeed convenient – for all proceedings to be resolved before a single forum by mutual consent. Once parties consensually agreed to vest jurisdiction in a single adjudicatory authority, neither could be permitted to simultaneously seek relief from another.
On the Trade Marks Act analogy, the Court held that the argument did not survive in light of its conclusion that simultaneous proceedings were impermissible to begin with. The absence of a provision similar to Section 124 of the Trade Marks Act in the Patents Act was therefore not a material gap in the present context.
Doctrinal Significance
This judgment is a landmark ruling in Indian patent law for several reasons.
It resolves the jurisdictional conflict between the IPAB and the High Court in patent revocation matters – a question that had created considerable uncertainty in IP litigation. By holding that the two remedies under Section 64(1) are mutually exclusive, the Court eliminated the possibility of parallel, conflicting adjudications on patent validity.
It establishes the “first-in-time” rule for patent revocation proceedings, creating a clear and predictable principle: whichever proceeding is instituted first – whether a revocation petition before the IPAB or a counter-claim before the High Court – will prevail and the later proceeding must be discontinued.
It settles the interpretive value of “Subject to” as a statutory preface, holding it to have substantive subordinating effect, as opposed to “notwithstanding” or “without prejudice to,” which carry opposite legal consequences. This distinction is important for the interpretation of subordinate clauses across Indian legislation.
It affirms the nature of a counter-claim as an independent suit, applying civil procedure principles (Section 10 CPC) to IP disputes, thereby bridging procedural law and substantive patent law.
It validates consent-based forum consolidation, confirming that parties in complex multi-suit IP litigation may agree by consent to vest jurisdiction in a single superior forum and such consent will be binding and enforceable.
It also has significance for the post-IPAB era, as the IPAB has since been abolished by the Tribunals Reforms Act, 2021 and its patent-related jurisdiction transferred to the High Courts. The principles articulated here regarding forum election and the bar against parallel proceedings remain relevant to understanding how revocation proceedings and counter-claims interact before the High Courts going forward.
