Their patent license is basically just saying that *if* google has any
patents, you are free to use them, and google will not sue you, so
that other big companies and organizations implement this without
taking forever to worry about google suing them.

http://www.waveprotocol.org/patent-license

"Google and its affiliates hereby grant to you a perpetual, worldwide,
non-exclusive, no-charge, royalty-free, irrevocable (except as stated
in this License) patent license for patents necessarily infringed by
implementation of this specification."

The revocation happens if you sue someone else for patent
infringement, it's really pretty positive, actually.
