More legal woes for Sony: the computing and consumer electronics giant is being sued by Pennsylvania-based Agere Systems over a number of devices spanning several product categories that, you guessed it, may be infringing upon some eight different Agere patents. Specifically, Agere is claiming that the PSP, PlayStation 2, and PlayStation 3 -- along with several Vaio, Handycam, Walkman, and Location Free TV models -- are in violation of patents covering such varied technologies as a "wireless local area network apparatus" and "barrier layer treatments for tungsten plugs," whatever those are. Furthermore, the integrated circuit component manufacturer believes that Sony "willfully" violated the patents, and is thus seeking damages that could end up being three times what non-willful infringements would warrant.
