Oracle has met with a set-back in its on-going patent infringement lawsuit against Google's Android platform.
The US Patents and Trademark Office, which was reviewing claims Oracle had made against Google, declared that 17 of the 21 claims cited by Oracle were invalid.
Oracle had filed a multi-billion dollar lawsuit against Google's Android, claiming the search engine giant had stolen code from the Oracle-owned Java platform, which it got when it acquired Sun Microsystems.
Upon inspection of US Patent No. 6,192,476, titled ‘Controlling access to a resource', the USPTO rejected 17 out of the 12 claims Oracle had made related to the patent. The patent covers the method by which a ‘principal' requests access to a software platform, CNET explains.
Oracle has six months to appeal the decision dealt by the USPTO; failing to do so would make the patent invalid and would reduce Oracle's chances of winning the lawsuit.
The rejection might still not be able to turn the tide in favour of Google, but it could add credibility to its claims that there are companies trying to stem the growth of Android by making bogus patent claims.
