What makes you suggest Karmarkar's algorithm as relevant to Indian patent law? As the Wikipedia article you linked points out, Narendra Karmarkar left India in 1978, getting an M.S. from Caltech in 1979, PhD from Berkeley in 1983, and briefly joining IBM in California as a post-doc (1983) and then AT&T Bell Labs (later in 1983): he came up with Karmarkar's algorithm while at IBM and applied for the patent while at Bell Labs, so everything related to it happened in the US. (The fact that Karmarkar was from India, or that he returned to India in the late 1990s, has no bearing here.)

(Unless your comment was about software patents in general, and not India's patent law specifically.)
