Peer-To-Peer Network Patent Application Rejected: Court Affirms CG's Decision

Peer-To-Peer Network Patent Application Rejected: Court Affirms CG's Decision

Introduction

Kroll Information Assurance, LLC (Appellant) filed an appeal against the order of the Controller General of Patents, Designs, and Trademarks (CG) refusing Indian Patent Application No. 8100/DELNP/2007. The application was for a system designed to locate individuals via a peer-to-peer network.

Factual Background

The patent application claimed priority from a US application dated April 12, 2005. The invention aimed to identify and mitigate the inadvertent or unauthorized sharing of sensitive data on peer-to-peer networks. The system used specific search terms to query the network, with the objective of profiling users or locating particular types of data based on the search results.

Procedural Background

The Appellant's application faced multiple objections during the examination, including non-inventiveness and being categorized as an algorithm or computer program per se, which are not patentable under Indian law. The CG refused the application on several grounds, including that the proposed amendments were beyond the scope of the original claims, the claims were non-inventive in light of prior art, and the subject matter was categorized as an algorithm or computer program per se.

Issues

1. Permissibility of Amendments: Whether the proposed amendments to the claims were permissible under Section 59 of the Patents Act.

2. Inventiveness: Whether the claims were inventive in light of prior art and contrary to Section 2(1)(ja) of the Patents Act.

3. Patentability: Whether the subject matter was patentable under Indian law, specifically Section 3(k) of the Patents Act.

Contentions of Parties

Appellant's Contentions: The Appellant argued that the CG erred in rejecting the proposed amendments, that the invention addressed a significant technical challenge, and that the hardware implementation was in amalgamation with the software modules. They also contended that the prior art D1 was not relevant and that the CG failed to establish the common general knowledge available on the priority date.

CG's Contentions: The CG rejected the application, stating that the proposed amendments were beyond the scope of the original claims, the claims were non-inventive in light of prior art, and the subject matter was categorized as an algorithm or computer program per se.

Reasoning & Analysis

The Court examined the invention and found that it primarily involved conventional computer operations and did not demonstrate a significant technical advancement over existing technologies. The Court noted that the search was performed based on keywords provided by the user, which reflected conventional computer program behavior. Therefore, it could not be stated that the computer program was enhancing the functionality of the hardware.

Final Outcome

The Delhi High Court concluded that the features claimed in Claims 1 to 7 fell under the category of computer program per se, and Claims 8 to 10 fell under the category of algorithms. Therefore, they collectively fell within the scope of excluded subject matter under Section 3(k) of the Act. The Court ruled that the invention did not demonstrate a significant technical advancement and fell within the excluded categories of algorithms and computer programs per se under Section 3(k) of the Act.

Implications

This case showcases the importance of demonstrating technical advancement and enhancing the functionality of hardware in patent applications related to computer programs and algorithms. Moreover, it emphasizes the need for careful consideration of prior art and common general knowledge in determining inventiveness.
