You can announce a patent grant once the U.S. Patent and Trademark Office issues the official grant notice, which happens after all claims have been allowed
The moment your patent is officially granted — not when claims are allowed, but when the USPTO issues the actual grant — you own the patent and can announce it publicly. The allowed claims stage and the granted patent stage are different points in the process, and the timing matters for what you can legally say.
When the USPTO sends you a "Notice of Allowance," it means the examiner has approved your claims. But you do not yet own the patent. You still need to pay the issue fee, and the USPTO still needs to publish the grant. Once you pay that fee and the USPTO issues the official patent certificate with a patent number, that is when you have a granted patent and can make a public announcement.
Key Takeaways
- A Notice of Allowance means claims are approved, but you do not own a patent until the USPTO issues the grant certificate after you pay the issue fee.
- You can announce a patent grant publicly once the USPTO publishes the official grant, which typically happens two to four weeks after you pay the issue fee.
- Announcing before the grant is issued can create legal confusion about what you actually own and may complicate enforcement later.
- The patent number and grant date appear on the official patent certificate, which is the document that proves you have a granted patent.
The difference between allowed claims and a granted patent
An allowed claim is a promise from the examiner that your claim will be part of your patent — but it is not yet a patent. The Notice of Allowance is an internal USPTO document saying the examiner has finished reviewing and found no reason to reject your claims. At this point, you have paid the examination fees, but you have not paid the issue fee, and the patent does not exist yet.
A granted patent is the finished product: a document issued by the USPTO with an official patent number, a grant date, and legal protection that begins on the date of grant. The grant certificate is what you can point to as proof of ownership. This is the document you would cite in a lawsuit, include in a licensing agreement, or list on a product as "Patent No. [number]."
The confusion arises because both stages feel like victories — and they are — but they are not the same thing. Many inventors and companies treat the Notice of Allowance as the finish line and announce it as if the patent is already granted. This can create problems later if someone challenges your patent or if you need to enforce it.
What happens between allowance and grant
After you receive the Notice of Allowance, you have three months to pay the issue fee. The fee amount depends on your entity type: as of 2024, it ranges from roughly $900 to $1,800 for most applicants, though the exact amount changes annually and varies by whether you are a large entity, small entity, or micro entity.
Once you pay the issue fee, the USPTO places your patent in the publication queue. The grant typically issues two to four weeks later, though this timeline can vary. During this waiting period, your patent does not yet exist in the public record, even though you have paid for it. You cannot legally enforce it, and you cannot claim damages for infringement that occurred before the grant date.
The USPTO publishes the grant in the Official Gazette and assigns an official patent number. This is the moment your patent becomes a real, enforceable legal document. This is also the moment you can announce it with full accuracy.
Why announcing before grant can backfire
If you announce a patent as granted before the USPTO actually issues it, you risk creating confusion about what you own. A potential licensee or investor may search the USPTO database, find no patent number, and conclude you were mistaken or exaggerating. This damages credibility at a critical moment.
More seriously, if you announce a patent before it is granted and then the patent is later invalidated or narrowed in a post-grant proceeding like an inter partes review, your public announcement becomes evidence that you made a false claim. Courts and competitors can use this against you in litigation.
There is also a practical enforcement problem: you cannot sue for infringement based on a patent that does not yet exist. If someone infringes your invention between your Notice of Allowance and your grant date, you have no legal recourse for that period, even if you announced the patent publicly.
How to know when your patent is actually granted
The clearest way to confirm a grant is to search the USPTO patent database at uspto.gov. Go to the Patent Search section, search by your application number or inventor name, and look for a record with an official patent number and a "Status: Granted" or "Status: Issued" designation. The patent number is always a seven or eight-digit number assigned only after grant.
You will also receive an official patent certificate in the mail from the USPTO, usually within a few weeks of the grant date. This certificate is the legal proof of ownership. It includes the patent number, the grant date, the title of the invention, the names of all inventors, and a summary of the claims.
Your patent attorney or agent will also notify you when the grant is issued, and they can help you confirm the details. If you are managing the application yourself, set a reminder to check the USPTO database about three weeks after you pay the issue fee.
What you can say at each stage
At the Notice of Allowance stage, you can accurately say: "Our patent application has been allowed" or "The examiner has approved our claims." This is truthful and does not overstate what you own. You can also say the application is pending grant, which is accurate.
Once the patent is granted, you can say: "We have been granted a patent" or "Patent No. [number] has issued." You can cite the patent number, the grant date, and the title. You can use the ® symbol next to the patent number if you choose, though this is optional.
The difference is small in words but large in legal meaning. One statement describes a stage in the process; the other describes a finished legal right.
Announcing your patent grant effectively
Once your patent is granted, a public announcement can be valuable for marketing, investor relations, and competitive positioning. Include the official patent number, the grant date, and a brief description of what the patent covers. This gives readers a way to verify the grant themselves by searching the USPTO database.
If you hold multiple patents or have a portfolio, you can announce them together once they are all granted. This creates a stronger narrative than announcing each one separately. You can also include the patent in your company website, product packaging, and marketing materials once it is granted.
Avoid language that suggests the patent is broader than it actually is. The claims define what the patent covers, and the patent does not cover everything in your invention — only what the claims describe. If you are unsure what your patent actually covers, ask your patent attorney to explain the scope before you announce it publicly.
Frequently Asked Questions
Can I use "Patent Pending" after I get a Notice of Allowance?
Yes. "Patent Pending" is accurate from the moment you file an application through the moment the patent is granted. It signals that you have filed and are waiting for the grant. Once the patent is granted, you should switch to the actual patent number instead of "Patent Pending."
What if my patent is granted but I have not received the certificate yet?
You can announce the grant as soon as you see it in the USPTO database with an official patent number and grant date. The physical certificate is a formality; the grant is official the moment the USPTO publishes it. You do not have to wait for the certificate to arrive in the mail.
Can I announce a patent grant if I am still in a post-grant proceeding?
You can announce the grant, but you should disclose that a post-grant review is pending if one is active. This is honest and protects you if the patent is later narrowed or invalidated. Your attorney can help you craft language that is accurate about both the grant and the ongoing challenge.
Does announcing a patent grant affect my ability to enforce it?
No. Announcing a granted patent does not weaken your enforcement rights. You can enforce a patent from the grant date forward regardless of whether you announced it. However, you cannot collect damages for infringement that occurred before the grant date, even if you announced it publicly during the allowed stage.
What if I announced my patent as granted before it actually was?
Correct the record as soon as you realize the mistake. Issue a clarification stating that the patent has now been granted with the official number and date. This is better than leaving a false announcement in place, which could be used against you later in a dispute.
