Requests For Reexamination Of Four Round Rock Patents Among Those Filed Week of 9/12/11

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

Requests for reexamination were filed against four RFID patents owned by patent-holding/enforcement company Round Rock Research (see ex parte Request Nos.

Earlier this year, Universal Electronics sued Logitech in the Central District of California for infringement of three touch-pad patents. Logitech has now replied by seeking reexamination of those patents (see inter partes Request Nos. (7), (8) & (9)).

As an update to our posts of June 30 & November 9, 2010 and January 19, 2011 – regarding inter partes reexamination requests filed by Whirlpool against four LG refrigerator patents – Judge Garrett Brown, in a parallel infringement action between the parties in the District Court of New Jersey, has denied Whirlpool’s motion to stay the case pending completion of the reexamination proceedings.  Judge Brown explained that inter partes reexaminations “could take more than five years if the parties fully exhaust their appeal rights” and that delay could cause LG irreparable loss because the parties are direct competitors: “[t]he goodwill lost during the reexamination proceedings could be difficult to measure and difficult to compensate fully with money damages after trial.” (more…)
