As far as I know Google are very open that they never use their patents offensively, they just have them as a defence against other companies attacking them with patents. I think that is still true today, can't find any articles about Google suing companies over patents without being sued first.

Now that Googles founders are no longer leading the company that might change, but so far their "do not be evil" still lives on in this regard, at least it did a few years ago.
