Between 2007 and 2011, 283 cases were identified in US Federal District Courts where patent validity was determined. Of these, only in 39 cases was the patent held valid and enforceable. In 253 cases, therefore, the patent was held to be invalid.
As against this, the Intellectual Property Appellate Board (IPAB) and the High Courts in India have revoked only 29 patents (10 of Indian Companies and 19 of Foreign Companies) during the 10-year period.”
In other words, US district courts have effectively invalidated almost 90% of all patents that have been challenged! That is one hell of a number! And yet the US government and some of the industrial masters that it serves make a huge song and dance when so much as one patent is invalided in India! Unfortunately, our mainstream press also contributes a bit to this negative perception as they gleefully recount the patent liquidations, while keeping mum about the patent wins.
