Case Note & Summary

The appeal arose from the rejection of Indian Patent Application No.951/CHENP/2013 by the Controller of Patents and Designs. The appellant, Navya Network Inc., sought a patent for an invention titled “Treatment Related Quantitative Decision Engine.” The Controller had issued a First Examination Report raising objections under Sections 3(k), 10(5), and on grounds of lack of novelty and inventive step. After hearing, the application was rejected by order dated 13.03.2023. The appellant challenged the rejection under Section 117A of the Patents Act, 1970. The appellant argued that the invention was not a computer programme per se because it resulted in a technical effect, relying on Microsoft Technology Licensing v. Assistant Controller of Patents and Designs. It also argued that the invention was not a business method and that the person skilled in the art should have included a medical expert. The appellant contended that the prior arts D2 and D3 did not render the invention obvious. The respondent maintained that the invention lacked inventive step and that both steps of the invention were anticipated by or obvious from D3, with the grading/scoring feature obvious from D2. The court analyzed the complete specification and found that the invention involved collating patient information, querying databases, and generating treatment scores using a generic computer. It compared the claimed features with prior art D3, which disclosed most features except quantitative scoring. Prior art D2 was found to disclose such scoring. The court held that the combination of D3 and D2 would have been obvious to a person skilled in the art. Consequently, the claimed invention lacked inventive step. The court further upheld the rejection under Section 3(k) as a computer programme per se and business method, noting the absence of any technical effect or improvement in computer functionality. The appeal was dismissed, and the Controller’s order was upheld.

Headnote

A) Patentability - Computer Programme Per Se - Exclusion - Patents Act, 1970, Section 3(k) - The invention claimed a system and method using a computer to generate treatment-related quantitative decision reports. The court held that the invention merely implemented a business method on a generic computer without demonstrating any technical effect or improvement in computer functionality, thus falling within the meaning of “computer programme per se” excluded under Section 3(k). Held that the objection under Section 3(k) was sustainable. (Paras 4, 7-12, 13)

B) Patentability - Business Method - Exclusion - Patents Act, 1970, Section 3(k) - Following Open TV Inc. v. The Controller of Patents and Designs, an invention is excluded as a business method if intended primarily to enable conduct or administration of a particular business. The court found that the invention involved collating patient information, querying databases, and generating treatment scores, which is essentially a method for conducting the business of medical treatment decision-making. Held that it was excluded as a business method. (Paras 4, 7-12, 13)

C) Patentability - Inventive Step - Obviousness - Patents Act, 1970, Sections 2(1)(ja) - The court examined prior art D3 and D2, holding that D3 disclosed all features of the claimed invention except quantitative grading/scoring. The court found that D2 disclosed such grading/scoring, and therefore the combination of D3 and D2 rendered the claimed invention obvious to a person skilled in the art. The invention also did not involve any technical improvement over a generic computer system. Held that the claimed invention lacks inventive step. (Paras 8-13)

Nature of Litigation

Appeal against order of Controller of Patents rejecting patent application under Section 117A of the Patents Act, 1970.

Remedy Sought

Appellant requested setting aside of the order dated 13.03.2023 and grant of patent for application No.951/CHENP/2013.

Filing Reason

The respondent Controller rejected the patent application on grounds including lack of novelty, lack of inventive step, exclusion under Section 3(k), and lack of clarity and conciseness under Section 10(5).

Previous Decisions

Controller of Patents rejected application on 13.03.2023.

Issues

Whether the claimed invention is excluded under Section 3(k) of the Patents Act, 1970 as a computer programme per se or business method. Whether the claimed invention lacks inventive step in light of prior art D2 and D3.

Submissions/Arguments

Appellant argued that the invention is not a computer programme per se because it results in a technical effect; it is not a business method; and it would not be obvious to a person skilled in the art, especially if considered by a team including a medical expert. Respondent argued that the invention primarily lacks inventive step and that both steps of the invention are anticipated by or obvious from prior art D3, with the grading/scoring feature obvious from D2.

Ratio Decidendi

A patent claim that merely implements a business method on a generic computer without demonstrating any technical effect or improvement in computer functionality is excluded under Section 3(k) as a computer programme per se. An invention is obvious if all its features are disclosed in prior art documents, and the combination of teachings from such prior art would render it non-inventive to a person skilled in the art.

Judgment Excerpts

The complete specification further discloses that this method and system involves formulating the medical question, quantitative representation of information sources, providing for queries to experts for expert feedback, literature analysis, reckoning patient preferences and risk tolerance and evaluating outcomes on the basis of an outcome database and machine learning so as to rank the treatment options and set out the same in the report. From the above discussion, it appears that prior art D3 contains most of the features of the claimed invention... The only feature not present in D3 is quantitative grading/scoring. That feature is, however, present in D2. In the face of such prior art, I am of the view that the claimed invention would be obvious to a PSITA. Consequently, the claimed invention lacks an inventive step. The conclusion that it is excluded under Section 3(k) of the Patents Act also cannot be found fault with in light of the above discussion. For reasons set out above, the impugned order is not assailable. Consequently, CMA (PT) No.13 of 2024 is dismissed.

Procedural History

The patent application was filed, First Examination Report issued on 21.11.2019 raising objections under Sections 3(k) and 10(5) and on grounds of lack of novelty and inventive step. The appellant responded on 21.08.2020 with amended claims. A hearing notice was issued on 13.12.2021, and the appellant submitted written submissions on 22.02.2022. The application was rejected by order dated 13.03.2023. The present appeal was filed under Section 117A of the Patents Act.
