USPTO Introduces a Pre-Order Paper Procedure at the SNQ Stage of Ex Parte Reexamination: Patent Owners Gain a 30-Day Pre-Institution Window

In an Official Gazette notice dated April 1, 2026, the USPTO introduced a new procedure for ex parte reexamination requests: before the Office determines under 35 U.S.C. 303(a) whether the request raises a substantial new question of patentability (SNQ), the patent owner may file a pre-order paper without a separate petition and without paying a fee. The submission is intended to help the Office assess why the argued teaching(s) in the request should not be considered sufficient to raise an SNQ at the threshold stage. The paper is generally limited to 30 pages, must be filed within 30 days after service of the request, and the deadline is not extendable. The third-party requester ordinarily may not respond, unless it obtains an exception through a petition under 37 CFR 1.182 with the required fee, in which case any responsive paper is limited to 10 pages.

What looks like a modest procedural adjustment is, in practice, a meaningful shift in the front end of U.S. patent disputes. Patent owners no longer have to wait until after reexamination is ordered before trying to shape the record in a sustained way. Instead, they now have an earlier opportunity to argue that the proceeding should not begin at all. For requesters, that change raises the importance of first-shot drafting quality, especially when framing a “new teaching” and explaining why the issue was not already decided or adequately examined before.

1. What the new procedure adds, and what it does not

The significance of the notice is not merely that it lets patent owners “speak earlier.” It creates a defined pre-order channel aimed specifically at the SNQ determination stage. The patent owner’s paper is supposed to explain why, even after considering the allegedly new teaching(s) cited in the request, the Office should maintain the patentability determination reached during examination for some or all challenged claims. In other words, this is not a free-form merits brief and not a vehicle for importing every downstream argument into the threshold phase.

The limits matter. The notice states that the paper should not address issues not raised in the request, and should not argue for discretionary denial under 35 U.S.C. 325(d), because that issue is taken up after the substantial-new-question determination. The paper must comply with the formal requirements of 37 CFR 1.52. A declaration may be submitted and will not count against the 30-page limit, but incorporation by reference is not permitted. The Office also made clear that the relevant rule waivers are automatic: if a compliant and timely patent owner pre-order paper is filed, the USPTO will waive 37 CFR 1.530(a) and the second sentence of 1.540 under 37 CFR 1.183 without requiring a separate petition or fee. That waiver applies only to proceedings in which the reexamination request was filed on or after April 5, 2026.

2. Why this reshapes the pre-SNQ defense window

For years, patent owners could certainly contest issues in ex parte reexamination, but the practical center of gravity often sat after institution. This notice moves part of that fight forward. The most consequential question is no longer only how to defend once reexamination has begun, but whether the patent owner can persuade the Office not to order reexamination in the first place.

That shift changes both timing and cost. A well-executed pre-order paper may help the patent owner prevent the proceeding from advancing beyond the threshold stage, reducing later briefing burdens, internal case-management strain, and business uncertainty. In procedural terms, the new mechanism gives the patent owner a structured opportunity to influence the record before the Office decides whether the requester has cleared the SNQ bar. That is a meaningful reallocation of leverage at the front end of the process.

3. The requester side now faces more pressure to get the opening paper right

From the requester’s perspective, the notice raises the value of getting the initial filing substantially right the first time. The USPTO expressly states that the requester ordinarily may not file a response to the patent owner’s pre-order paper. Only in limited circumstances — for example, to address alleged material misrepresentations of fact or law, or other improper arguments that materially impede the SNQ determination — may the requester seek leave through a petition under 37 CFR 1.182 and the required fee. Even then, the response is capped at 10 pages and must be filed within 15 calendar days after service of the patent owner’s paper, with no extension.

That means requesters have less room to assume that later procedural rounds will cure a weak opening submission. The notice also confirms that existing MPEP guidance remains in effect: an SNQ must still be based on a “new teaching,” meaning a new, non-cumulative technical teaching or a new light that escaped earlier review. If the alleged teaching is not actually new, the Office will continue to refuse reexamination on that basis. As a result, the requester’s opening paper now carries even more responsibility for explaining not only why the cited art matters, but why the issue was not previously resolved, sufficiently examined, or merely repackaged from the prior record.

4. Practical next steps for patent owners, requesters, and cross-border teams

This development is important enough to warrant operational changes now, rather than ad hoc reactions later. At a minimum, teams should consider the following:

• For U.S. patent owners: build a “30-day after service” response protocol for ex parte reexamination requests, with pre-developed argument frameworks addressing non-new teaching, lack of materiality to a reasonable examiner, and issues already covered in earlier examination or review.
• For requesters: improve one-shot drafting quality in the request itself, especially on the new-teaching theory and on why the asserted issue was not previously decided or fully examined; also budget for the possibility of a 37 CFR 1.182 petition if a limited response becomes strategically necessary.
• For cross-border clients and internal U.S.-facing teams: add the April 5, 2026 effective-date threshold to dispute-risk alerts, intake forms, and U.S. reexamination assessment templates so that timing assumptions do not distort case strategy.
• For managers and practice leaders: treat the pre-order paper not as just one more filing, but as evidence that the front end of U.S. reexamination practice is becoming more layered. The teams that can institutionalize rapid record review, prior-prosecution reconstruction, and compressed argument development will likely be in the strongest position to convert this 30-day window into a real procedural advantage.

Overall, the USPTO has not changed the statutory SNQ standard, but it has changed the information structure around the threshold determination. Patent owners now have a formal, no-petition, no-fee route to speak before the Office decides whether to order ex parte reexamination, while requesters face stronger pressure to front-load quality into the initial request. The notice also signals that, if the mechanism proves helpful, the Office may consider rule revisions. For parties that regularly deal with U.S. patent disputes, this is not simply another procedural update; it is a development that should be reflected in workflows, budgets, and early-stage case strategy.
