Dispute Summary
Microsoft Technology Licensing appealed the refusal by the Assistant Controller of Patents and Designs to grant a patent for its computer-related invention, 'Delegating Instant Messaging Sessions'. The core dispute centered on whether the software met the criteria for patentability under Section 3(k) of the Patents Act. The Madras High Court ruled in favor of Microsoft, emphasizing that an invention based on a computer program is not automatically excluded if it demonstrates a clear technical effect or contribution, aligning with international jurisprudence and revised Patent Office guidelines.
