IPR petitioners Proppant Express Investments, LLC and Proppant Express Solutions, LLC (collectively, “PropX”) have a pending instituted inter partes review (IPR) on certain claims of U.S. Patent No. 9,511,929 (“the ’929 patent”).  Unfortunately for PropX, it mistakenly grouped its arguments against one of the dependent claims—claim 4—into the wrong ground, which led the Patent Trial and Appeal Board (the “Board”) to deny institution of IPR of that claim, due to inadequate support.  IPR2017-02103, Paper 19 at 32, 34.  After institution, PropX sought to amend the petition to move claim 4 into the proper ground.  The Board denied PropX’s request because PropX was not diligent: despite Patent Owner’s (“Oren”) Preliminary Response pointing out PropX’s mistake, PropX failed to notice the mistake until after institution.  IPR2017-02103, Paper 22.
