HTC Claims Intervening Rights Against Apple In ITC Case

Scott Daniels, Partner at Westerman, Hattori, Daniels & Adrian and Practice Center Contributor, sent in this article discussing the pending ITC investigation of HTC’s mobile communication devices.  Daniels raises interesting questions regarding HTC’s latest motion asking the ITC  for a determination that it does not infringe one of Apple’s patents because it’s entitled to “absolute intervening rights” against Apple.

HTC might be making a comeback in the ITC’s investigation of mobile communication devices  (337-TA-710).  In July Administrative Law Judge Charneski issued an Initial Determination (ID) against HTC, finding that its accused communication devices infringe two data manipulation patents owned by Apple.  That determination, if affirmed by the full Commission, would likely result in exclusion from entry into the United States of HTC’s infringing devices.

But in September the full Commission announced that it was reviewing Judge Charneski’s ID against HTC.  And, in a step that will interest reexamination practitioners, HTC asked the ITC for a determination that it does not infringe one of the Apple patents – U.S. Patent No. 5,946,647 – because HTC is entitled to “absolute intervening rights” created in a co-pending reexamination of Apple’s ‘647 patent.
