The patent in the video is US 6857067. Claims 1, 20, 22, 30, 31, 67, 107, and 108 were invalidated by the Patent Office in an administrative proceeding, but claims 21 and 22 survived that particular challenge. See IPR2013-00391, Final Decision. Cost for these challenges is around $300k (and often much less for troll suits), rather than the $2-5 million that is typically quoted for district court cases.
