No problem, Sony stuffed the channels for two years now: there are years of ps3 supply in teh OVERSTUFED CHANNELZ!!!!!!
What, 2/3 weeks? In the biggest market for Sony? Come on...
One must enforce a patent as soon as there is a possible infringement, if you don't enforce your patent then the patent is void. PS3 was on the market for almost 5 years, so, if they filed their complaint this year, they risk to lose their patents.
BTW this is a counter-suit to a suit filed by Sony, to block the import of LG Smartphones (including the WP7 ones).
