This Supreme Court judgment addressed the protracted nature of patent infringement litigation, specifically concerning Bajaj Auto Ltd versus TVS Motor Company Ltd.

Vittal Mallya Scientific Research Foundation v.Indfrag Limited
The applicants filed three applications seeking supplementary instructions to IIT, Madras, to examine whether the respondent's production process for Double Metal Salt of HCA infringed upon the applicants' patents.

Arun Colour Chem & Ors. v.Mithumal Essance Mart & Anr
The Delhi High Court stayed a complex infringement suit involving trademark and copyright claims related to the 'SUN BRAND' food colour label.

The Delhi High Court addressed applications filed by the defendants seeking to set aside an ex parte decree passed against them in a suit involving trademark, copyright, and passing off claims.

Bayer Corporation v.Union of India
Bayer Corporation, holding a patent for the drug Sorafenib tosylate, challenged the licensing process of its competitor, Cipla, arguing that Cipla's application for 'Soranib' constituted an infringement. Bayer contended that granting the license would violate Section 48 of the Patents Act and contravene the definition of a 'spurious drug' under the Drugs and Cosmetics Act. The Delhi High Court ultimately dismissed the writ petition, holding that unpatented drugs cannot be deemed 'spurious drugs,' thereby upholding the procedural integrity of the licensing process.
