Fractus Patents Hit with Nine More Reexamination Requests

Here is the latest  installment of Reexamination Requests from Scott Daniels, of Reexamination Alert and Practice Center Contributor….

In our post of November 22, 2010, we described Samsung’s strategy for defending against allegations that it and several other cell phone makers infringe nine antenna patents owned by Fractus – specifically by vigorously defending in the Eastern District of Texas and requesting reexamination at the PTO against all nine Fractus patents.  Now it appears that co-defendant Kyocera has filed its own set of reexamination requests against the “Fractus Nine” (Inter partes Nos. (5) to (11), (13) below).  Not all the details of the new requests are publically available because these new requests were paper-filed and because of certain procedural problems.  It is quite likely, however, that these requests will be granted and merged with Samsung’s earlier reexaminations.

Also of interest is a request filed by Abbott Diabetes Care Inc. against a DexCom patent for transcutaneous analyte sensors.  Abbott and DexCom spared in reexamination over that technology in the past, for instance regarding U.S. Patent Nos. 6,931, 327 and 7,276,029. (more…)
