Microsoft WMV In Patent Trouble?

thpr writes "According to rethink, Microsoft may be violating patents in their Windows Media software. Apparently, the VC1 standard (from The Society of Motion Picture and Television Engineers), which has been pushed by Microsoft, depends on patents owned by other companies - more than likely, those that have patents used in the previous MPEG standards. According to the sources in the story, both Sony and Philips may take the case to court, rather than continuing negotiation. As they point out in a later update, Sony might be pleased to have a say in the competing HD-DVD format. Is this a 'major speed bump to Microsoft's dominance of digital media markets'?" Well, the answer, IMHO, is probably not - this is a negotiation issue. But this is a wonderful example of how intertwined legal & software issues can become.

For instance, its wording on motion estimation in patent number 5,692,063 could be used to describe the techniques in H.264 just as easily. This refers to the technique whereby a processor can predict which pixels will be covered in the next few frames by an object that is moving.

Hmm...this technique is usually used by anyone in motion video or you will get screen flicker if you redraw the entire screen every frame.

Also, if these other companies are using WMV, wouldn't it be in their best interest to have their codec distributed with the huge marketshare of Windows users? I'm not sure if they were planning on selling a codec and what the market is to actually buy one. If I download something and it doesn't work with my standard codecs, I delete it.
