Microsoft Technology Licensing, LLC v. The Assistant Controller of Patents and Designs

Microsoft appealed the Patent Controller's decision to reject its patent application for a method of authenticating users in network sub-locations. The Controller had ruled the invention was a "computer program per se" and thus not patentable under Section 3(k) of the Patents Act, 1970. The High Court found the Controller had misinterpreted Section 3(k) by not recognizing the technical effect and contribution of the invention beyond being a mere computer program. The court clarified that inventions involving computer programs can be patentable if they provide a technical solution or advancement. The Controller's rejection was set aside, and the case was sent back for reassessment of novelty and inventive step. Result: Appeal against refusal of patent application allowed; Controller's order set aside; matter remanded for re-examination on grounds of novelty and inventive step.
