In case you forgot, Google was involved in a little spat with Oracle earlier this year, in which a jury decided that Oracle's patents were not infringed by Google, and a judge came to the conclusion that Oracle's assertion regarding API copyright infringement was untenable.

Judge Alsup's reasoning in denying Oracle's infringement claim was, to anyone with a technical background, quite reasonable. Oracle had claimed that while the amount of line-for-line literal infringement Google committed against the 37 infringed Java APIs through its Dalvik virtual machine was minimal (read: 97% of Google's code was original), the fact that Google had copied created its functional equivalent constituted copyright infringement.
