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…)
