Oracle’s legal tussle with Google over the alleged infringement of one key Java patent within the Android OS has suffered a massive blow.
According to new reports, United States Patent and Trademark Office (USPTO) authorities have dismissed 17 of the 21 claims by Oracle over the alleged violation of the patent..
Oracle earlier stated that the patent in question, patent#6192476 is one of the 6 disputed patents that Google “violated” with its Android operating system.
As revealed by a Groklaw report on the story, the USPTO turned down the 17 claims by referring to prior art. Relieved by the decision, the California based search giant appealed to the USPTO to reexamine the remaining 4 claims as well.
Earlier in May, the honorable judge hearing the case had asked Oracle to narrow its volume of claims from the original 132.
There are hundreds of prior art references in play for invalidity defenses. This is too much," William Alsup, the district judge said, The Register reports.
The judge also asked Google to lower the number of its invalidity defenses saying, "Many of Google's invalidity contentions are inconsistent and presented in the alternative: Google contends that many patent claims are not enabled but also contends that the same claims are enabled by the prior art."
