In inter partes review (IPR) proceedings, the scope of a petitioner’s response is often a contentious point. A recent decision in Rembrandt Diagnostics v. Aler by the Federal Circuit provided an in-depth analysis of the permissible breadth of a petitioner’s responding arguments. It emphasized the crucial role of maintaining responsiveness to both the patent owner’s feedback and the arguments outlined in the initial petition.
Authored by John Alemanni and Michael Morlock, both of Kilpatrick, the detailed discussion illuminates how parties in IPR often grapple to distinguish whether a reply to a patent owner’s response is truly a response, or merely an effort to present new arguments not reasonably linked to the originally presented claims. This issue holds crucial implications for the outcome of such proceedings and the strategy employed by parties engaged in IPR.
