MPEG-LA preparing patent attack on Google’s WebM

MPEG-LA, the patent collective that licenses the popular h.264 video codec, has issued a call for patents that may underlie Google’s competing WebM codec. Google released the codec license-free shortly after acquiring it last year. However, it is widely expected that Google may not have acquired all relevant patent licenses. MPEG-LA says that it hopes to establish a patent pool and license the codec itself.
