The lawsuit probably showed up because of MS using the technology in a way that's hindering the sales of their own product. However, 'Project Natal' was announced June 1 2009, and the Trazer brand was created June 28 2009. It almost seems like the spent a million dollars creating a product for their patents, just to be able to justify the patents in court and become profitable by winning in court.
