Mitsubishi Chemical Corporation v. Assistant Controller of Patents and Designs, Government of India

Pawan Kumar GoelvsDr. Dhan Singh & Anr.

The plaintiff filed a suit claiming infringement of Patent 369150, which covers a novel process for extracting Alpha Yohimbine. The plaintiff sought an interim injunction to stop the defendants from using or manufacturing the subject compound. However, the court noted evidence presented by the defendants showing they were already manufacturing the compound through a similar process prior to the patent application date.

The Hershey CompanyvsAshok Kumar & Ors.

The Hershey Company successfully sought the expansion of its existing interim injunction against new parties found to be engaging in trademark infringement. The Delhi High Court allowed the plaintiff to implead several new defendants and extended the protective order, specifically restraining them from using or reproducing the company's name and marks on domains like THEHERSHEYCOMPANY.IN. This ruling reinforces the court's willingness to expand injunctive relief when evidence reveals additional infringing parties.
