The U.S. Patent and Trademark Office has implemented a procedural change allowing patent owners to submit a limited response to ex parte reexamination requests before the agency decides whether to institute review. Previously, the institution decision was made based solely on the requester’s submission, with the patent owner only participating after a reexamination had already been ordered. Under the new framework, patent owners can now present arguments at the threshold stage, including why the request fails to raise a substantial new question of patentability, giving examiners a more balanced record at the outset.

This shift is expected to meaningfully alter reexamination strategy. Patent owners now have an incentive to act quickly and marshal strong, targeted arguments early, while requesters may face greater pressure to submit more robust and well-supported petitions in anticipation of an immediate response. The change effectively front-loads advocacy on both sides, which could improve the quality of institution decisions and streamline the overall process. By equipping examiners with competing perspectives earlier, the procedure may also reduce the likelihood that marginal or unsupported requests proceed to full reexamination.

In addition, the rule has broader implications for efficiency and resource allocation within the USPTO. Earlier screening informed by both parties’ positions may conserve agency time and costs by limiting unnecessary proceedings, while also providing greater predictability for stakeholders. Over time, this could lead to a decrease in the volume of instituted reexaminations and a more selective, refined use of the process.
