Patent Notice of Allowance: 7 Essential Next Steps

Few pieces of mail feel as good as a patent notice of allowance. After months, sometimes years, of prosecution, the USPTO is telling you your claims are allowed. But allowance is not a grant, and the celebration comes with a countdown. From the day that notice is mailed, you have a hard, non-extendable deadline to pay, decisions to make about related filings, and a term calculation worth checking. Miss a step and you can lose the patent you just earned — or leave months of patent term on the table.

What a Patent Notice of Allowance Really Means

A patent notice of allowance (form PTOL-85), issued under MPEP 1303, is the USPTO’s formal statement that your application contains allowable subject matter and will issue as a patent once you pay the required fees. It lists the allowed claims and includes a Fee Transmittal (form PTOL-85B) for paying the issue fee.

Read it carefully. Allowance is a milestone, not the finish line. Your application is still pending, which means you retain a few valuable options that close forever the moment the patent issues. Understanding what is still on the table now is what separates a routine grant from a costly missed opportunity.

The 3-Month Issue Fee Deadline You Cannot Extend

This is the deadline that matters most. Under 37 CFR 1.311, the issue fee and any required publication fee must be paid within three months of the mailing date of the notice. That three-month period is not extendable. Miss it and your application goes abandoned.

• Pay via the Fee Transmittal (PTOL-85B); the form pre-lists the amounts due.
• Confirm the current issue fee on the USPTO fee schedule before you pay — fees change.
• Calendar the deadline from the mailing date, not the date you opened the envelope.
• If you have missed it, your only route back is a petition to revive, not an extension.

There is no safety net of extension fees here the way there is for an office action response. If the deadline slips, see our guide to the petition to revive a patent application — but treat that as an emergency exit, not a plan.

What to Verify Before You Pay

Before you send the issue fee, proofread the bibliographic data the USPTO will print on your patent. Errors caught now are simple to fix; errors caught after issuance require a certificate of correction.

• Inventor names and order, spelled exactly as they should appear on the patent.
• The assignee name and whether you want assignment data printed on the face of the patent.
• The allowed claim set — confirm no claim was inadvertently canceled or renumbered.
• Any required formal drawings, if the examiner conditioned allowance on corrected figures.
• The specification and title for obvious typographical errors.

Filing an IDS or Continuation After Allowance

Allowance is your last clear chance to act while the application is still pending, and two moves deserve attention. First, your duty of disclosure does not switch off at allowance. If you become aware of material prior art, you can still file an Information Disclosure Statement — under 37 CFR 1.97(d) an IDS after allowance requires a statement and a fee, and the QPIDS pilot lets you submit one even after paying the issue fee without forcing a full reopening. See our IDS timing rules for the mechanics.

Second, if you want broader claims, a different claim scope, or protection for embodiments you did not pursue, you must file a continuation or divisional before the patent issues to preserve co-pendency. Once it grants, that door closes. Our continuation application guide walks through when it’s worth the filing.

• IDS after allowance: allowed, but it carries a statement requirement and a fee.
• Continuation or divisional: must be filed before issuance to keep the chain alive.
• Deferral of issuance: you can request a short deferral if you need time to file a related case.

Patent Term Adjustment: Check the USPTO’s Math

Most guides skip this, and it can be worth months of exclusivity. Under 35 U.S.C. 154(b), the USPTO adds Patent Term Adjustment (PTA) to compensate for its own examination delays. The Office calculates PTA and shows it on the notice of allowance and again on the issue notification — but the calculation is not always right.

Check it. If the USPTO undercounted its delay or overcounted applicant delay, you can request reconsideration of the PTA determination, generally within two months of the patent’s grant date. Every extra day of term is extra market exclusivity, so a quick review here often pays for itself. Our patent term adjustment guide explains how the counting works.

After You Pay: Issue Notification, Grant, and Maintenance Fees

Once the issue fee posts, the USPTO processes the application for issuance. You will receive an Issue Notification listing your patent number and the anticipated grant date, typically a few weeks out. On that date the application becomes an enforceable United States patent.

Then the maintenance clock starts. Utility patents require maintenance fees at 3.5, 7.5, and 11.5 years from the grant date to stay in force. Docket them the day the patent issues; a lapse can put your rights at risk. Our guide to patent maintenance fees covers the schedule and grace periods.

Deferring Issuance to Buy Yourself Time

Sometimes the three months move faster than your business does. Maybe you are finalizing a licensing deal, deciding whether to file a continuation, or coordinating a coordinated release of related patents. In those cases you can ask the USPTO to defer issuance of the patent for a short period after the issue fee is paid.

Deferral is granted for good and sufficient reason and only for a limited time, so it is a tactical tool, not an open-ended pause. The most common reason is to keep the application pending just long enough to get a continuation or divisional on file, preserving the family while you decide on claim scope. Used deliberately, a short deferral can be the difference between a rushed decision and a well-planned portfolio.

Weigh it against the cost of delay: every day the patent is not granted is a day you cannot enforce it. If nothing genuinely requires more time, pay the fee and take the grant. The moment your patent notice of allowance converts into an issued patent, your rights become enforceable and your competitors are on notice.

What Happens If You Miss the Deadline

If the three-month issue fee window passes unpaid, the application is abandoned. Recovery is possible but not guaranteed: you file a petition to revive under 37 CFR 1.137, state that the delay was unintentional, and pay the revival fee plus the issue fee. It is slower, more expensive, and more paperwork than simply paying on time.

• Abandonment is automatic — the USPTO does not send a warning before the deadline.
• Revival requires a petition, a statement of unintentional delay, and a fee.
• Prevention is a two-line docket entry; cure is a petition. Choose prevention.
