Patel Field Marshal Agencies and Anr. v. P.M. Diesels Ltd. and Ors.
Background
The respondent, P.M. Diesels, held registered trademarks for "Field Marshal." In 1982 the appellants applied to register the similar mark "Marshal," prompting a long-running infringement suit by the respondent (filed 1989) that bounced between the Delhi High Court and a Gujarat court over jurisdiction for nearly two decades. Separately, the appellants had tried to get the respondent's trademark registrations cancelled through a rectification proceeding before the Gujarat High Court, which was dismissed and upheld on appeal: that dismissal is what reached the Supreme Court in this bunch of appeals.
Decision Breakdown
The core legal question was whether a party can still seek cancellation of a trademark via a separate rectification application under Sections 46/56 of the Trade and Merchandise Marks Act, 1958, after having raised (and not pursued, or having had rejected) the same invalidity plea inside a pending infringement suit under Sections 107/111. The Court held that once a civil court trying an infringement suit frames the issue of invalidity and the aggrieved party fails to pursue rectification before the statutory authority within the time allowed, the right to raise that invalidity question is deemed permanently abandoned: it cannot be revived later through a separate rectification application. Applying this, the Court dismissed all the appeals and upheld the High Courts' rulings against the appellants.
Lesson Learnt
If you want to challenge the validity of someone else's registered trademark while an infringement suit is already pending, you must pursue that challenge through the proper rectification process within the time the court allows, missing that window forfeits the right to raise the same challenge again later in a separate proceeding.
