Here are all the patent cases in which Google was a plaintiff. They appear to all be declaratory judgments against NPE defendants.

There is a difference between being a plaintiff in a patent case and using patents offensively. In the Skyline case, it looks like Skyline sued Google over Google Earth: http://googlecopyright.blogspot.com/2007/03/google-prevails-...

Sidebar question: how did you find these? I'm researching a related topic and need to perform bulk searches for patent related litigation data. Any suggestions or advice would be greatly appreciated.

That makes no sense. How can you sue a non-practicing entity for infringing your patents? If they're non-practicing, they're not doing anything.

Being a plaintiff doesn't always mean you're the one suing. It could be an appeals court case where the positions are reversed. Also, you could sue an NPE in order to invalidate their patent(s), or to seek an injunction.
