In a recent judgement, the Delhi High Court, while hearing an appeal against an order of the Controller of Patents and Designs, which refused a patent grant, distinguished between a technical method and a business method while examining the technical contributions/ effects of an invention. In the impugned order, the Controller refused a patent application titled “Methods and Devices for Authentication of an Electronic Payment Card using Electronic Token” on the grounds that the claimed invention falls under Section 3(k) of the Patents Act (“Act”), categorising it as a business method and a computer programme, per se.
