In a patent case filed in the Eastern District of Texas by Eon Corporation IP Holdings, LLC (“Eon”) against Cellco Partnership d/b/a Verizon Wireless (“Verizon”), along with other defendants, Eon moved to dismiss Verizon’s inequitable conduct counterclaims and strike its inequitable conduct affirmative defenses. Magistrate Judge Love recommended that Eon’s motion to dismiss be denied because Verizon’s inequitable conduct claim was sufficiently pled.
Verizon’s inequitable conduct was based on two separate instances. First, Verizon alleged that the sole inventor of the asserted ‘491 patent deliberately withheld his earlier patent from the U.S. Patent Office (“PTO”) with the intent to deceive the PTO. Second, Verizon alleged that the ‘491 patent should be found unenforceable under the “infectious unenforceability” doctrine because it was obtained due to Eon’s inequitable conduct of its parent patent application. In denying Eon’s motion, the Magistrate held that Therasense did not substantially alter the pleading requirements and that Verizon sufficiently plead inequitable conduct under the standard set forth in Exergen Corp. v.
