Well, on the bottom of the page it says "Innovation Alliance" which is "[...] a coalition of research and development-based technology companies representing innovators, patent owners, and stakeholders from a diverse range of industries that believe in the critical importance of maintaining a strong patent system that supports innovative enterprises of all sizes."
Here is a list of some(?) of their members: http://innovationalliance.net/about-us/
