Earlier today, Engadget editor Nilay Patel tweeted a link to a website titled FOSS Patents, maintained by Florian Mueller, who is devoted to covering lawsuits based on software patents — a complex issue, without a doubt.

FOSS Patents has posted a 13-slide document outlining the complex lawsuits between several smartphone manufacturers, including Apple, Motorola and HTC, play-by-play.

You can view all of  the documentation as a PDF here.

Needless to say, this is a complex situation, with lawsuits layered upon lawsuits. It’s pretty mind-boggling, honestly. Software patent law is more complicated than most of us can really understand, but thankfully, sites like Mueller’s really help sort things out.
