Revised Federal Petition Standard Shortens Window to Restore Lapsed Patent Rights

DETROIT, MI, September 16, 2026 /24-7PressRelease/ -- Patent owners who allow an application to become abandoned, or a granted patent to expire for nonpayment of maintenance fees, now have a narrower opportunity to restore those rights through the U.S. Patent and Trademark Office's standard petition process. Under a revised practice that's been in effect since August 13, 2026, petitions filed more than one year after the relevant deadline must be supported by a detailed account of the delay and carry a higher government fee.

The change is significant for Detroit-area manufacturers, automotive suppliers, and technology companies, whose portfolios are frequently transferred through acquisitions and corporate restructuring. Those transitions are often where maintenance deadlines and correspondence records are overlooked. The Patent Baron, PLLC, whose Detroit patent attorney brings more than 20 years of intellectual property experience, is advising patent owners in the region to review the status of their portfolios without delay.

Scope of the Revised Petition Practice

Published as a final rule on June 24, 2026, the change governs petitions to revive abandoned applications, accept late maintenance fee payments, accept late priority or benefit claims, and excuse missed deadlines in international design applications. Previously, the USPTO generally required additional information only when a petition was filed more than two years after the relevant date. That threshold is now one year. Later petitions must explain the circumstances establishing that the entire delay was unintentional, and the agency's current fee schedule raises the large-entity petition fee from $2,260 to $3,000, with reduced amounts for small and micro entities.

"Lapsed patent rights are most often the product of an administrative oversight, such as a reminder sent to an outdated address or a docket that was not transferred along with the portfolio," noted J. Baron Lesperance, who founded the firm and has been registered to practice before the USPTO since 2005. "The revised rule makes early detection considerably more important, because the burden on the patent owner increases substantially once the first year has passed."

Recommended Steps for Patent Owners in the Detroit Area

• Confirm that addresses of record are current and that maintenance fee dates are tracked. The USPTO sends maintenance reminders only to the address on file, and a missed notice does not excuse a missed deadline.
• Review nonprovisional applications meant to claim the benefit of earlier provisional applications, since an improperly presented benefit claim falls under the same one-year threshold.
• Distinguish intentional lapses from inadvertent ones. A patent dropped through deliberate budgeting decisions does not qualify for relief based on unintentional delay.
• Act promptly once a lapse is identified. A late maintenance fee petition filed within one year costs less and generally requires no additional explanation.

A statement of unintentional delay also carries consequences beyond the USPTO. The Federal Circuit's decision in In re Rembrandt Technologies illustrates the risk. Patents that a prior owner had intentionally allowed to lapse, then revived by describing the delay as unintentional, were held unenforceable for inequitable conduct. The USPTO cites that decision in the revised rule.

"A statement of unintentional delay is a formal representation to a federal agency, and it may be scrutinized closely if the patent is ever asserted," Lesperance added.
