FORTUNE — In July, FOSS Patents‘ Florian Mueller looked at the number of major publicly traded companies that have filed patent infringement suits against devices running on Google’s (GOOG) Android platform (seven with a total market cap of $1.06 trillion) and the number of Apple (AAPL) and Microsoft (MSFT) patents Android devices have been found by a court to infringe (11 as of July 1).

On Wednesday, Mueller updated his list of Apple and Microsoft patent infringements. The total, adjusted for rulings that have gone both for and against Android devices, is now 17. (See list below.)

“Android continues to be an IP infringement lawsuit magnet,” Mueller wrote in July. “As an Android user, I would like to see Google address those problems more effectively. When I look at public statements made by Google officials, it sometimes seems that the company is, at different levels, in a state of denial concerning Android’s intellectual property issues.”

As if on cue, Google chairman Eric Schmidt weighed in from Seoul, where according to the Korea Times he was “rap[ping] Apple for patent trolling” at a Nexus 7 launch event:

“Patent wars prevent choice, prevent innovation and I think that is very bad. We are obviously working through that and trying to make sure we stay on the right side of these issues. So ultimately Google stands for innovation as opposed to patent wars.”
