Microsoft has not fared well in the re-examination business. ChannelWeb reports:

n February, Microsoft Corp. challenged 24 of Avistar Communications Corp.'s 29 patents, but later added the remaining five to the list. As of the close of the market last week, 14 of Microsoft's re-examination requests were rejected by the Patent Office. The Patent Office did, however, authorize the re-examination of nine of Avistar's patents. The remaining six patents remain in limbo, as the office has not issued a decision on them.
