Bayer Pharm Aktiengesellschaft v. The Controller General of Patents And Designs

This case concerns an appeal against the refusal of a patent application for a pharmaceutical composition. The Controller initially rejected the application on grounds that it involved a mere admixture and a method of treatment. The High Court found procedural irregularities because one of the rejection grounds (Section 3(e)) was not communicated to the applicant before the hearing, violating natural justice. Furthermore, the Court determined that the claimed invention described a product, not a method of treatment, thereby misapplying Section 3(i). The High Court therefore set aside the refusal and sent the matter back for a new review, emphasizing proper communication of all objections. Result: The patent refusal order was set aside and the application was sent back to the Controller for a fresh decision, with directions for proper procedure and a hearing.
