Last week Google petitioned the Supreme Court of the United States for permission to appeal the Federal Circuit decision to overturn their victory against Oracle. You may remember that Oracle sued for patent and copyright infringement over Google’s use of a small subset of the huge Java class API in Android. Oracle lost in front of a jury in the district court in San Francisco, but then won on appeal.

The case will be a significant landmark for the technology industry regardless of the outcome, but the real impact of any decisions reached will be felt first by Android. The petition itself then suggests that the wider impact of the case is narrower than others might have feared, as its effects only come into play with substantial systems of APIs. Still, in the event of an Oracle win, open-source-licensed APIs would suddenly become much more important and the work of creating developer ecosystems around proprietary APIs would become much more challenging.

The Google petition includes three detailed and thorough arguments for the overturning of the Federal Circuit decision. For a look into what those arguments are and more on the significance of the case, try Simon’s InfoWorld article.
