Cisco Challenge to Two VirnetX Network Patents, among the Reexamination Requests Filed Week of December 12, 2011

Scott Daniels | December 20, 2011

VirnetX, having long ago vanquished Microsoft, is now in a difficult infringement action in the Eastern District of Texas against Cisco and a number of other network-makers.  Last week Cisco requested reexamination of two VirnetX patents (see inter partes Request Nos. (3) & (8) – U.S. Patent Nos. 7,418,504 and 7,921,211. 

Knowles Electronics is involved in a rather complicated litigation position.  First, it sued Analog Devices in Illinois for infringement of U.S. Patent Nos. 7,439,616 and 7,537,964, and then, at the beginning of this month, it filed an ITC Complaint against Analog Devices, Amkor and Avnet for infringement of the ‘964 patent, plus infringement of U.S. Patent No. 8,018,049.  Reexamination requests were filed last week against the ‘964 and ‘049 patent (see inter partes Request Nos. (1) & (2)), and reexamination was requested against the ‘616 patent last May.  This multi-front dispute creates another opportunity for interaction between the respective forums.

Reexamination is rarely requested for design patents, but two requests were filed last week (see ex parte Request Nos. (7) & (17)).  Challenges by reexamination to design patents seem to do much better than those in District Court.

Volkswagen requested reexamination of a GPS patent owned by Beacon Navigation who has sued a number of automakers for infringement of the patent (see inter partes Request No. (4)).
