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…)

Samsung Attack on Antenna Patents among Reexamination Requests Filed Week of September 27th

Here is this week’s  installment of Reexamination Requests from Scott M. Daniels, of Reexamination Alert and Practice Center Contributor….

Samsung filed reexamination requests (Inter partes Nos. 4, 10 and 11) last week against three Fractus patents for antennas.  Fractus had sued Samsung and quite a number of other wireless companies, including LG, Research in Motion, Kyocera, HTC, Sharp and Sanyo, for infringement of those patents.

Also of interest is a request (Inter partes No. 1) filed by CEJN AB against Westendorf Mfg.’s U.S. Patent No. 7,717,471 for a hydraulic line device.  The two companies are already in a reexamination of Westendorf’s U.S. Patent No. 7,021,668 – the examiner’s rejection of the claims of the ‘668 is now before the PTO Board of Appeals.

Finally, Encore filed a request (Inter partes No. 12) against a Southwire patent for electrical cables.  Southwire is noted among ITC practitioners for having filed in the late 1970’s the first major Section 337 complaint. (more…)
