Government has revoked a patent granted to Avesthagen by the Indian Patents Office for a medicine made from the extract of jamun, lavangpatti and chundun meant to treat diabetes. The patent given to the mix of jamun, lavangpatti and chundun proved to be a major embarrassment, given that India has for long fought for protecting traditional knowledge and genetic resources and sought to check piracy of ayurvedic and other traditional forms of medicine. What is even more curious is how the Indian Patents Office gave the protection after the government had successfully got European authorities to turn down the application two years ago.

The company, however, argued that the extracts, which work individually in managing diabetes, had an aggressive effect when combined. In addition, it used an approach that is "innovative, novel and scientific" in developing a formulation and screened it for efficacy and safety using modern technology.
