Database giant Oracle faced a major setback in the patent litigation against Google, with USPTO rejecting some claims of patent (US6192476) which is one among the several patents that Oracle asserts against Google.
Oracle sued Google last year, claiming that the Google Android operating system uses Java Virtual machine technology and it violates a number of Java patents it acquired along with Sun Microsystems.
Google on the other hand requested the USPTO to re-examine the Oracle patent (US6192476) titled as "Controlling access to a resource”. Last week, U.S. Patent and Trademark Office rejects 17 claims out of 21 claims in patent (US6192476) and it basically means that the patent is invalid since many of the claims have been rejected. Oracle now has six months to appeal for the USPTO's decision. If it fails, then Oracle will probably be stripped of the patent.
"Patents were meant to encourage innovation, but lately they are being used as a weapon to stop it” opined Google's chief legal officer David Drummond.
