Delhi High Court Imposes Costs for “Unnecessary Litigation” in Patent Suit
Key Issue:
Whether a plaintiff can withdraw a suit with liberty to refile when its own evidence undermines the foundation of the claim.
Facts:
In Pawan Kumar Goel v. Dr. Dhan Singh & Anr., the plaintiff instituted a patent infringement suit alleging unauthorised use of a patented process relating to the extraction of Alpha Yohimbine. During the proceedings, an expert report submitted by the plaintiff itself concluded that the defendant’s extraction process was materially different from the patented process in question.
In light of this development, the plaintiff sought withdrawal of the suit with liberty to institute fresh proceedings. It was further argued that the dispute could be reframed on a different basis by focusing on issues relating to raw material rather than the extraction process itself.
The defendant opposed the request, contending that the plaintiff was attempting to avoid the consequences of its own evidence and prolong litigation without a valid legal basis.
Judgement:
The Delhi High Court declined to permit withdrawal with liberty to refile and imposed costs of ₹50,000 on the plaintiff. The Court observed that the plaintiff’s own expert evidence had substantially weakened the infringement claim and that permitting withdrawal in such circumstances would effectively allow a party to circumvent legal limitations.
The Court further clarified that the patent in question covered only the extraction process and not the raw material itself. Therefore, the plaintiff could not subsequently reshape the dispute to sustain an otherwise untenable claim.
The ruling reinforces that litigation must be pursued responsibly and parties may face consequences where proceedings are found to be unnecessary or unsupported by their own evidence.
