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

When sued for patent infringement, Apple’s strategy this year has been to request reexamination of the patents-in-suit as soon as possible.  It repeated that strategy this week by filing inter partesr equests against two MONKEY Media patents (see Inter partes Request Nos. (3) & (5))..

DNA2.0, Inc. has requested reexamination of U.S. Patent No. 5,786,464 owned by NIH for “Over-expression of Mammalian and Viral Proteins” (see Ex parte Request No. (12)).   An ironic aspect of this conflict is that DNA2.0 is a past recipient of grant money from NIH.  (more…)

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…)
