Another patent battle for Android

back prior to 1996 I was working at Radio Shack and I remember that you could have two phone numbers on one phone line, with the different numbers having different ring patterns. You could buy devices that would detect the different rings to direct the incoming call to a fax machine or phone. This would seem like direct prior art for the '131 patent.

the '937 patent seems to be obvious since Windows had been popping up windows for controls over the content for quite a few years.

the others seem similarly weak, but I don't have as obvious prior art at the tip of my fingers.

I hope Google guts these patents with prior art (land war in asia, or engaging Google in anything involving searching for information...)
