That is a potential problem, but for MPEG-1 it is less of a problem than with newer codecs.  Since the near complete MPEG-1 committee draft was publicly available in December 1991, remaining patents for decoding of the full MPEG-1 spec should be expiring in the 2012 timeframe or before. 

The next question is why not just wait until the complete MPEG-1 can be decoded? If there is still no decision on a suitable codec for HTML5 when MPEG-1 becomes royalty free and MPEG-1 decoding starts showing up in things like gstreamer's good set of plugins then the full MPEG-1 might be worth considering then.
