‘In Vitro Detection’ Still Diagnostic: Nematode Cancer Test Barred under Section 3(i)

Close-up of a dictionary page with the word “Diagnosis” highlighted in bright green by a chisel-tip highlighter, emphasizing the term against surrounding text.

In Hirotsu Bio Science v. Assistant Controller of Patents and Designs, the Delhi High Court held that branding a process as “in vitro detection” does not rescue it from Section 3(i) when, in substance, it diagnoses cancer. The nematode-based urine test was thus refused as an excluded diagnostic method.

You Can’t Park Patent Rights in the E-Ricksha Registration Lane

In the case of M/s Sunhok Wheels Pvt. Ltd. & Ors. vs The State of West Bengal & Ors., the Calcutta High Court addressed whether claims of patent rights can prevent registration of e-rickshaws.

Is a Smarter Scooter Frame Patentable? Court Orders Rethink on Inventive Step

The Delhi High Court refused Novo Nordisk interim relief against Dr Reddy’s, finding that the Semaglutide species patent faces serious validity challenges in light of the earlier genus patent. The Court allowed Dr Reddy’s to continue manufacturing Semaglutide in India solely for export to non-patent jurisdictions, with no domestic sales.

Once the Hearing Is Fixed, the Door Closes on New Evidence in Patent Oppositions

In the case of M/s Hi Tech Chemicals Limited vs Deputy Controller of Patents and Designs & Anr., the Madras High Court examined whether documents labeled as additional evidence could be admitted after the hearing was fixed in a post-grant patent opposition. The Court looked at the patent rules, and held that private documents do not qualify as “publications” under Rule 62(4), and are therefore not admissible after the hearing date was fixed.

Patent Refusal Cannot Be a Single Line: Calcutta High Court Calls for Reasoned Orders

Yellow road marking with bold black text reading “SINGLE LINE. DO NOT CROSS,” symbolizing the lack of reasoning in the Stromag GmbH patent refusal—a single-line decision that violated principles of natural justice.
