On one hand:
http://www.mpegla.com/Lists/MPEG%20LA%20News%20List/Attachme..."Parties with patents or patent applications determined by MPEG LA’s patent experts to be essential to the H.264/AVC standard (“standard”) so far include Columbia University, Electronics and Telecommunications Research Institute of Korea (ETRI), France Télécom, Fujitsu, Matsushita, Mitsubishi, Microsoft, Motorola, Nokia, Philips, Polycom, Robert Bosch GmbH, Samsung, Sharp, Sony, Thomson, Toshiba, and Victor Company of Japan (JVC)."
On the other - I don't see Motorola here: http://www.mpegla.com/main/programs/AVC/Pages/Licensors.aspx
So I'm a bit confused about whether Google just managed to buy into AVC/h264 or not.
