Patent rights for processes do not confer exclusive rights over products derived from those processes, impacting enforcement and claims for injunction.

Headnote:(A) PATENTS ACT, 1970 - Sections 2(1), 3, 48, 64 - Patent infringement - Petitioner sought injunction due to alleged infringement of patents IN370845 and IN434424 regarding ferric carboxymaltose - Court held that no prima facie case was made for interim injunction as the patent rights claimed did not extend to the product itself, only to the process of making it. (Paras 38-42)

(B) Legal Principles - Court emphasized the distinction between product and process patents, affirming that claims must demonstrate novelty and inventive steps beyond known processes. (Para 29)

(C) Who can enforce patent rights - It was ruled that only patentees or lawful licensees have the right to exploit the patented process or product. (Para 8)

Facts of the case:
The petitioner, a pharmaceutical manufacturer, claimed infringement of its patents on ferric carboxymaltose due to respondents’ similar product promotion. The respondents argued the patents were not valid or novel. (Paras 1-10)

Findings of Court:
No prima facie case for an injunction was established; the patentee lacked rights to prevent competition in a product not uniquely theirs. (Paras 38-42)

Issues: The primary issue was whether the patents claimed granted exclusive rights on the product itself or merely on the process of making it, affecting the validity of infringement claims. (Paras 40-41)

Ratio Decidendi: The court reasoned that patent rights for processes alone do not confer exclusive rights over the products derived from those processes; thus, an injunction cannot be justified on such claims. (Paras 40-41)

Result: The request for interim injunction was dismissed.
