    HAMILTON IP LAW successfully defended U.S. Patent No. 7,140,569 (’569 Patent) against a challenge to the validity of its claims via an inter partes review (IPR) proceeding before the Patent Trial and Appeal Board (PTAB) at the U.S. Patent and Trademark Office.

    The patent, owned by Genesis III, Inc., covers forged hammers used in grain and feed material milling and grinding systems. The ’569 Patent has been successfully asserted previously in various litigation cases against other manufacturers including Jacobs Corporation and Black Diamond.

    HAMILTON IP LAW opposed the institution of the IPR against Genesis III's '569 Patent. On January 22, 2015, in Jacobs Corporation v. Genesis III, Inc. the PTAB denied the IPR petition in all respects, finding that it failed to demonstrate a reasonable likelihood that any of the challenged claims would be held invalid under any of several proposed theories.

    HAMILTON IP LAW managing partner and co-counsel for this matter, Jay R. Hamilton, noted the following:

    Contrary to what patent infringers may believe, the USPTO’s post-grant proceedings do not allow infringers to act with impunity against the exclusive rights enjoyed by a patent owner. This decision denying the trial demonstrates that patent challenges at the USPTO can be defeated before expenses become crippling. The PTAB's decision has strengthened the ’569 Patent, recognizing the validity of all the patent claims in view of the three different proposed grounds of invalidity.

    Mr. Hamilton, Hamilton IP Law partner Charles A. Damschen, and attorney Alexander JSW Johnson collaborated on this effort. Mr. Max Petersen and Kevin Erickson, partners at Pauley, Petersen and Erickson in Hoffman Estates, Illinois served as special counsel to Hamilton IP Law. The victory comes amid the firm’s active momentum in cases before the PTAB; Hamilton IP Law filed an ex parte challenge of validity against U.S. Pat. No. 7,942,616 on behalf of its client, Karma, Inc., in proceeding No. 90/012,666 against Allied Machine & Engineering Corporation. Allied’s ’616 patent is the subject of ongoing litigation which is presently stayed due to Allied’s appeal from the PTAB’s decision invalidating all claims of the ’616 patent.
