OpenTV Inc. v. The Controller of Patents and Designs & Anr.

Relevant Acts and provisions

Patents Act, 1970

Section 15Section 3(k)Section 59

Provisions considered: Sections 3(k) and 59 of the Patents Act, 1970, on the business method exclusion and permissible claim amendments.

Brief facts

OpenTV's national phase application for a system and method to provide gift media was refused under Section 15 on the grounds that the claims fell within the business method exclusion under Section 3(k) and that amendments made during prosecution exceeded the permissible scope under Section 59. On appeal, OpenTV sought to recast its method claims as system claims to overcome the business method objection.

Issues before the Court

1. Can a patent applicant amend claims at the appellate stage, and within what limits does Section 59 permit this?
2. Does a claim to a system for gifting media items fall within the exclusion of business methods under Section 3(k)?

Court's findings

The Court held that amendments at the appellate stage are permissible, since an appeal is a continuation of the original proceedings and the High Court has the same power to require amendment of claims as the Controller possesses under Section 15; however, any such amendment must remain within the scope of the claims as originally filed.

The Court found that converting the originally filed method claims into system claims, so as to add new system claims never part of the original application, impermissibly broadened the scope of the claims contrary to Section 59, and accordingly refused to allow that amendment.

On Section 3(k), the Court held that the business method exclusion is absolute and, unlike the exclusion for computer programmes per se, is not qualified by any technical-effect test. It held that the substance rather than the form or nomenclature of the claims governs the enquiry, so that merely relabelling a business method as a system claim cannot avoid the statutory bar.

Decision

Appeal dismissed; the Controller's refusal on both the Section 3(k) and the Section 59 grounds was upheld.
