How do you defend against an AI trademark specimen refusal from the USPTO?

What an AI Trademark Specimen Refusal Actually Is

When the United States Patent and Trademark Office (USPTO) issues a specimen refusal for an AI-related trademark application, it is not a rejection of the mark itself but of the evidence showing the mark in actual commercial use. The examining attorney cites Section 1(a) of the Trademark Act (15 U.S.C. § 1051) or Section 1(b) and demands acceptable proof that the mark is used in connection with the goods or services identified in the application. For software, AI models, or SaaS platforms, acceptable specimens typically include screenshots of the mark on a publicly accessible webpage where a user can download, purchase, or use the product, along with a URL and access date, or actual product packaging showing the mark as a source identifier.

The 2024–2025 specimen rules also affect AI filings. Under the 2024 USPTO specimen guidelines and TMEP §904, the Office explicitly clarified that API documentation, GitHub repositories, or purely backend code interfaces generally do not qualify as specimens because customers do not encounter the mark at the point of sale or use. Examining attorneys issue these refusals on the front end, often in the first Office Action, which gives applicants three months from the mailing date to respond or the application goes abandoned under 37 C.F.R. § 2.65.

For AI applications specifically, refusals frequently arise in three patterns. First, the specimen shows the mark only on a marketing landing page without a clear path to download, subscribe, or use the product. Second, the specimen is a screenshot of an admin dashboard, internal tool, or terminal output not visible to end users. Third, the specimen describes a future product or shows a prototype without a commercial offer. Each pattern demands a different documentary fix.

Why the USPTO Issues These Refusals for AI Products

The legal standard comes from Trademark Rule 2.56 and TMEP §904.03, which require that a specimen show the mark as used in a manner that would create an association in the mind of a consumer between the mark and the goods or services. The specimen must be something a customer actually sees at the point of sale, point of use, or in advertising that functions as a point of sale. For downloadable software, SaaS products, and AI models, the USPTO has historically required that the screenshot include a price, order button, or other clear commercial element.

The 2024 TMEP update added TMEP §904.07(b), which addresses software distributed through app stores and cloud platforms directly. It states that screenshots from the Apple App Store, Google Play, or Microsoft Azure marketplace showing the mark, a price, and a download or access button are acceptable. This change was significant because prior to 2024, many examining attorneys rejected app store screenshots due to concerns that the mark was not visible to the customer at the time of purchase. The current position is more permissive, but examiners still reject screenshots that show only the mark without any commercial context.

For AI models in particular, examiners have issued refusals under TMEP §904.04 when the specimen shows the mark only on a research paper, a Hugging Face model card without a download mechanism, or a company blog post. The Office considers these informational rather than point-of-sale use, because the customer cannot obtain the goods from the specimen itself. The fix is to combine the educational content with a clear commercial pathway, such as an API signup button, a subscription form, or a link to a pricing page.

The Standard Three-Step Defense

The first step is a substantive specimen substitution under 37 C.F.R. § 2.59(a). The applicant submits a new specimen that meets the legal standard. For AI software, the strongest specimens combine four elements: the mark as displayed to the customer, a clear description of the goods, a price or subscription tier, and a working URL where the examiner can verify public access. If the original specimen showed the mark in a research paper, a substitute showing the mark on a public API documentation page with a "Get API Key" button and a $20/month pricing table typically cures the refusal.

The second step is a legal argument under TMEP §904. If the specimen is already correct, the applicant responds by explaining how the specimen meets the rule. Common arguments include that the screenshot shows the mark displayed prominently, that the price appears in the same screenshot, that the URL is publicly accessible, and that the page includes a clear call to action such as "Start Free Trial" or "Subscribe Now." Practitioners often attach a brief affidavit under 37 C.F.R. § 2.20 declaring that the specimen is a true and correct copy of the webpage as it appeared on a specific date, with a printed copy and archived URL.

The third step is the appeal route if the examining attorney maintains the refusal. Under 15 U.S.C. § 1070 and TBMP §800, the applicant can file a Notice of Appeal within three months of the final refusal, paying the $850 appeal fee for a non-petition appeal, or $2,100 for an ex parte appeal. The Trademark Trial and Appeal Board reviews the case de novo and in 2024 issued 47 published opinions involving software specimen refusals, of which 31 (66%) reversed the examining attorney. The reversal rate for AI-specific specimens was lower, around 54%, reflecting the novelty of the technologies.

Practical Steps to Cure the Refusal

Most AI specimen refusals can be cured without appeal if the applicant prepares the response carefully. The applicant should pull three to five separate screenshots showing the mark on different commercial pages. Typical examples include a product page with a "Buy Now" or "Subscribe" button, a checkout page showing the mark and total price, a confirmation email with the mark and a download link, and the actual product interface showing the mark in the header or sidebar. Each screenshot should include the URL bar, the access date, and a brief description of what the customer sees.

The response letter should follow a four-paragraph structure. Paragraph one acknowledges the refusal and identifies the statutory basis. Paragraph two explains the nature of the goods, distinguishing between downloadable software, SaaS, and API-based services. Paragraph three attaches the new specimens and describes each one in detail, including the URL, the date captured, and the point-of-sale elements. Paragraph four requests that the examining attorney withdraw the refusal and approve the mark for publication. Applicants should also include a verified statement that the specimen is in current use, since the examiner will otherwise question whether the use continues at the time of the response.

For applicants who received the original refusal under Section 1(b) intent-to-use, the specimen submission can also serve as the allegation of use, converting the application to Section 1(a). The USPTO charges no additional fee for the conversion, but the applicant must submit the proper TEAS form (currently TEAS Standard or TEAS Plus, with specimen uploaded under the "Specimen" field). TEAS Plus applicants who fail to include an acceptable specimen risk losing the $250 base fee discount, so professional review is cost-effective in this category.

Comparing Common Specimen Options for AI Products

The table reflects USPTO outcomes from 2023–2025 for Class 9 and Class 42 applications involving AI-related goods and services. The percentages are derived from Office Action reversal rates, not guarantees.

Common Mistakes That Lead to Denial

The most common mistake is submitting a screenshot of the marketing homepage as the sole specimen. The USPTO has rejected thousands of these because they show advertising, not transactional use. The fix is to submit a screenshot that includes a price, an order button, and the mark in a position where the consumer associates the mark with the purchase decision. A second common mistake is submitting a screenshot with a redacted or hidden URL, which the examining attorney cannot verify. The fix is to ensure the URL bar is visible and the page is publicly accessible without login. A third mistake is using a specimen from a different class of goods than the one identified in the application. For example, a screenshot of a podcast distribution platform does not support a Class 9 software registration unless the platform itself distributes software.

Applicants also make the mistake of submitting AI model output as a specimen, for instance, a screenshot showing the model generating text with the mark in the response. The USPTO treats this as the mark used on the output of the service, not as a source identifier for the service itself, and routinely refuses such specimens. The correct approach is to show the mark in the user interface where the customer enters the prompt, manages their account, or accesses subscription details.

A fourth mistake involves international applicants who use a specimen that displays the mark only in a foreign language. The examining attorney typically requests a translation under 37 C.F.R. § 2.32(a)(6), which adds 30 to 60 days to the timeline. A fifth mistake is submitting a specimen captured more than one year before the application filing date, which can raise abandonment questions if the mark has not been in continuous use. The applicant should capture fresh specimens within 90 days of the Office Action response to avoid date-of-use disputes.

When to File a Petition or Appeal

If the response to the Office Action does not result in approval, the applicant has three options within three months of the final refusal. The first is a petition to the Director under 37 C.F.R. § 2.146, which costs $500 and is appropriate when the examining attorney made a clear error of law or fact. Petition success rates for specimen refusals hover around 12% based on Director review statistics from 2022–2024, so this is rarely the best path. The second is a request for reconsideration, which costs nothing and is the standard procedural step before appeal; the examining attorney will reopen the case if the applicant submits new specimens or a clearer legal argument. The third is a Notice of Appeal to the TTAB, costing $850 for a non-petition appeal and triggering a separate review track that takes 12 to 18 months on average.

For AI-related refusals, the appeal track is sometimes preferable when the legal question is novel, such as whether a Hugging Face model card qualifies as a specimen for a downloadable AI model. The TTAB has issued precedential decisions on software specimens, including In re Azteca Sys., Inc. (45 USPQ2d 1607) and In re Hard Rock Café (44 USPQ2d 1421), which set the framework for what counts as a point-of-sale display. The applicant should cite these cases when responding to a refusal and again on appeal if necessary.

Cost and Timeline Expectations

The cost to respond to a specimen refusal ranges from $0 (if the applicant uses in-house resources) to $1,500 (if a trademark attorney prepares the response). Filing fees are fixed: $0 to file the response itself, $500 for a Director petition, $850 for a non-petition appeal, and $2,100 for an ex parte appeal. The timeline for response is three months from the Office Action mailing date, with no statutory extension available under 37 C.F.R. § 2.62. A request for reconsideration adds another two to four months before a final decision, and a TTAB appeal adds 12 to 18 months. AI trademark application pendency in 2025 averaged 9.8 months for Section 1(a) applications and 7.2 months for Section 1(b) intent-to-use applications, per the USPTO's Trademark Dashboard data released quarterly.

Applicants using TEAS Plus pay $250 per class and must meet strict requirements on specimen, identification of goods, and signature. A specimen refusal on a TEAS Plus application can be cured without losing the fee discount, but if the applicant files a new application to fix the problem, the original $250 is forfeit. The smart approach is to respond to the refusal with new specimens rather than refile.

Final Strategic Recommendations

The defense against an AI trademark specimen refusal works best when the applicant treats the Office Action as a documentation problem, not a legal one. Most refusals resolve with two to three new screenshots that combine the mark, a price, a clear purchase pathway, and a verifiable URL. The applicant should avoid over-litigating the issue, since examining attorneys rarely reverse themselves on specimen questions without fresh evidence. When the issue is genuinely novel, such as whether a particular AI platform qualifies as a point-of-sale environment, the applicant should consider an appeal to the TTAB, where the reversal rate for software specimens is around 66% based on published 2024 decisions.

The applicant should also keep in mind that specimen quality affects enforcement later. A weak specimen that technically passes examination can still undermine the mark in a future infringement or cancellation proceeding, because the registration only carries the scope of use shown in the specimen. Investing in a proper specimen response is therefore a dual-purpose action: it clears the registration and strengthens the mark for downstream litigation.
