Trademark Registration for AI Startups: Surviving USPTO Descriptiveness Refusals

You named your product "AI Writer." It's clear, it's catchy, and it tells customers exactly what the tool does. Then the USPTO office action arrives: refusal under Section 2(e)(1) — the mark is merely descriptive. If you're an AI startup founder, this scenario is playing out with increasing frequency. As the volume of AI-related trademark applications surges, USPTO examining attorneys are issuing descriptiveness refusals for marks that incorporate terms like "AI," "Chat," "Bot," "Gen," or "Smart" alongside functional descriptors. The good news: a descriptiveness refusal is not the end of the road. In this guide, we walk through why AI-named products get flagged, what your options are for overcoming the refusal, and how to choose a registrable brand name from the start.

Why the USPTO Keeps Rejecting AI Product Names

The Lanham Act, codified at 15 U.S.C. §1052(e)(1), prohibits registration on the Principal Register of any mark that, "when used on or in connection with the goods of the applicant, is merely descriptive or deceptively misdescriptive of them." The USPTO lists descriptiveness as one of the most common grounds for refusal of a mark in its official overview of possible grounds for refusal.

For AI startups, the problem is structural. Terms like "AI," "artificial intelligence," "machine learning," "chat," "bot," and "generative" have become part of the everyday vocabulary of the technology industry. When your mark combines one of these terms with a word that describes what your product does — "AI Writer" for an AI-powered writing tool, "ChatBot Pro" for a chatbot platform, "SmartDocs AI" for document processing — the examining attorney concludes that consumers will immediately understand the mark as describing a feature, function, or purpose of the goods rather than identifying a specific source.

The USPTO's Trademark Manual of Examining Procedure (TMEP §1209.02) directs examining attorneys to consider "the evidence of record" — including dictionary definitions, industry usage, press articles, and the applicant's own specimen and website text — to determine whether a mark is merely descriptive or instead suggestive or arbitrary. The examining attorney will look at how the terms in your mark are used in the marketplace, and if "AI" combined with your functional word is widely used to describe that category of product, the refusal follows.

Merely Descriptive vs. Deceptively Misdescriptive

There's an important distinction. Under §2(e)(1), a mark is "merely descriptive" if it describes an ingredient, quality, characteristic, function, feature, or purpose of the goods. A mark is "deceptively misdescriptive" if it misdescribes the goods and consumers would reasonably believe the misdescription. For AI startups, the most common scenario is the merely descriptive refusal: your name accurately describes what your product does because it literally names the technology and the function. But deceptively misdescriptive refusals can also arise — for example, if your product name includes "AI" but your product doesn't actually use AI, or uses it in such a limited way that the term misleads consumers about a material aspect of the product.

Anatomy of a Descriptiveness Office Action

When the USPTO examining attorney issues a descriptiveness refusal, it arrives as part of an Office action — an official letter from the examining attorney. A first Office action is never final, which means you have an opportunity to respond. The action will cite §2(e)(1), explain why the mark is merely descriptive of the identified goods or services, and often include dictionary definitions, website screenshots, or industry articles showing that the terms in your mark are used descriptively in the relevant market.

The examining attorney's reasoning typically follows a formula: they identify each component of your mark, show that each component has a recognized meaning in the industry, and conclude that the combination merely conveys information about the product. For "AI Writer," the action might cite the dictionary definition of "artificial intelligence" and the common meaning of "writer" as a tool or person that produces written content, then conclude that the mark as a whole tells consumers the product is an AI-based writing tool.

The Office action will also typically advise you of your options. As the TMEP explains, if the mark "appears to be capable" of functioning as a mark — meaning it's not generic — the examining attorney should advise you about the possibility of amending to the Supplemental Register or claiming acquired distinctiveness. You typically have three months to respond (with possible extensions), so timing matters.

Strategies to Overcome a Descriptiveness Refusal

You have several paths forward when you receive a §2(e)(1) refusal. The right strategy depends on your mark, your budget, your timeline, and how much market traction you've already built.

1. Argue the Mark Is Suggestive, Not Descriptive

The first option is to argue that the examining attorney got it wrong — that your mark is not merely descriptive but suggestive, and therefore registrable on the Principal Register. A suggestive mark requires consumers to use "imagination, thought, or perception" to reach a conclusion about the nature of the goods, while a merely descriptive mark conveys information about them immediately.

This argument works best when your mark includes an element that creates a conceptual distance from the product's function. If your mark is "AI Writer," this argument is a steep climb — the terms are transparent. But if your mark uses a coined term or an unexpected juxtaposition — say, "Lumina AI" for a writing tool — you may have a genuine argument that the mark requires mental steps to connect it to the product. The examining attorney will consider the mark as a whole, not just the individual words, so a distinctive overall commercial impression can sometimes carry the day.

2. Amend to the Supplemental Register

If the mark is capable of acquiring distinctiveness but hasn't yet, you can request to amend your application from the Principal Register to the Supplemental Register. The USPTO's guidance on amending to the Supplemental Register explains that this register is "a second trademark register where trademarks can be registered that are not yet eligible for registration on the Principal Register, but may, over time, become an indicator of source."

A Supplemental Register registration provides real benefits: you can use the ® symbol, the registration is protected against conflicting marks in later-filed USPTO applications, and it can serve as a basis for foreign filings. However, it does not carry the same presumptions of validity and exclusive right to use as a Principal Register registration. Critically, after five years of continuous use on the Supplemental Register, you can seek to move the mark to the Principal Register by claiming that it has acquired distinctiveness.

There's one important limitation: marks filed under §66(a) (Madrid Protocol) cannot be registered on the Supplemental Register. If you filed via the Madrid system, this option isn't available to you.

3. Claim Acquired Distinctiveness Under §2(f)

If your mark has been in use long enough that consumers now recognize it as a source identifier — meaning they associate "AI Writer" with your company specifically, not just any AI writing tool — you can claim acquired distinctiveness under Section 2(f) of the Lanham Act. The USPTO's guidance on claiming acquired distinctiveness outlines the types of evidence you can submit:

• Advertising and promotional materials showing the mark used as a trademark and source identifier
• Dollar figures for advertising devoted to promoting the mark
• Dealer and consumer statements indicating recognition of the mark as a trademark
• Other evidence showing consumer recognition of the mark as identifying your goods

The statute provides that "substantially exclusive and continuous use" of the mark for five years before the claim of distinctiveness can serve as prima facie evidence. In practice, the USPTO often accepts a claim of five years' continuous use for marks that are merely descriptive (as opposed to generic), but the examining attorney may still request additional evidence. For a young AI startup that launched six months ago, this option may not be realistic yet — which is why many founders pivot to the Supplemental Register as an interim strategy.

One critical caveat from the TMEP: if the examining attorney believes the mark is generic — not merely descriptive — a §2(f) claim will not save it. Generic terms can never be registered, regardless of how much consumer recognition they've acquired. If your mark is the common name for the category of product itself, no amount of evidence will overcome the refusal.

4. Pivot or Rebrand

Sometimes the most cost-effective strategy is to rebrand. If your mark is highly descriptive and you're early enough in your company's lifecycle that a name change won't cause significant disruption, pivoting to a more distinctive name can save months of back-and-forth with the USPTO and thousands of dollars in legal fees. A suggestive or arbitrary mark — one that doesn't immediately describe what your product does — will face far fewer hurdles at the examining attorney's desk.

We've seen founders resist this option because they've already invested in a domain name, logo, or marketing materials. But the cost of rebranding at the seed stage is almost always lower than the cost of fighting a losing descriptiveness battle, especially if the mark is borderline generic. And as we discuss in our guide to deliberate trademark and brand protection strategy, building your brand on a registrable foundation from the start is one of the highest-ROI legal decisions a founder can make.

Best Practices: Choosing a Registrable AI Brand Name From Day One

The best way to survive a descriptiveness refusal is to avoid triggering one. Here are practical principles for choosing an AI product name that is more likely to clear the USPTO:

Avoid the "AI + Function" Formula

Marks that combine "AI" (or "ML," "Gen," "Chat," "Bot") with a word describing what the product does are the most likely to be refused. "AI Writer," "ChatBot Pro," "SmartDocs AI" — these are textbook merely descriptive marks. The examining attorney will find dictionary definitions, industry articles, and competitor usage showing that each component describes the product.

Use Coined or Arbitrary Elements

The strongest marks are coined (invented words like "Kodak" or "Exxon") or arbitrary (common words used in an unrelated context, like "Apple" for computers). For AI products, consider a coined name that evokes but doesn't describe your technology, or an arbitrary word paired with a suggestive tagline. A name like "Anthropic" for an AI company doesn't describe what the product does — it requires the consumer to make a mental connection, which is the hallmark of a suggestive or arbitrary mark.

If You Must Use "AI," Create Conceptual Distance

If including "AI" in your name is important for marketing reasons, pair it with an element that creates conceptual distance from the product's function. "AI" combined with a coined word, a geographic reference unrelated to the product, or an arbitrary term is more defensible than "AI" combined with the literal function. The examining attorney evaluates the mark as a whole, so a distinctive overall impression can shift the mark from merely descriptive to suggestive.

Conduct a Knockout Search Before Filing

Before you file a trademark application — and ideally before you commit to a name — conduct a knockout search in the USPTO's trademark database (Trademark Center) and on the web. Look not just for identical marks but for similar marks in related classes. This won't definitively predict a descriptiveness refusal, but it will help you avoid a likelihood-of-confusion refusal, which is the other most common ground for rejection. As we discuss in our AI startup legal strategy guide, trademark clearance is one of the non-negotiable legal basics for any technology startup.

Think About the Long Game

Trademark registration is not a one-time event — it's a multi-year process with maintenance requirements. A mark that registers on the Supplemental Register today can move to the Principal Register in five years if you build consumer recognition. Conversely, a mark that barely clears the descriptiveness threshold now may face challenges later if the industry adopts the terms in your mark more broadly. Our guide to trademark lifespan and renewals covers the maintenance timeline you should plan for.

Actionable Next Steps

If you've already filed and received a descriptiveness refusal, here's what to do:

1. Read the Office action carefully. Identify the specific basis for the refusal (§2(e)(1) merely descriptive vs. deceptively misdescriptive) and the evidence the examining attorney cited. You typically have three months to respond, with the option to request extensions.
2. Evaluate your mark honestly. Is it merely descriptive, or is there a genuine argument that it's suggestive? If the mark is "AI" + your product's function, be realistic about the odds.
3. Consider the Supplemental Register. If your mark is capable of acquiring distinctiveness but hasn't yet, amending to the Supplemental Register gets you a registration, the ® symbol, and a path to the Principal Register after five years of continuous use.
4. Gather §2(f) evidence if you have it. If you've been using the mark for five or more years with substantial exclusive use, or you have significant advertising spend and consumer recognition data, a §2(f) claim may overcome the refusal.
5. Talk to a trademark attorney. Responding to an Office action is a legal proceeding. An experienced trademark attorney can assess the strength of your arguments, draft a response that addresses the examining attorney's specific reasoning, and help you weigh the cost of continuing versus rebranding.

If you haven't filed yet, the best move is to choose a distinctive, registrable name from the start. Avoid the "AI + function" formula, use coined or arbitrary elements, conduct a knockout search, and consult with a trademark attorney before you invest in branding, domains, and marketing. The upfront cost of getting the name right is a fraction of the cost of fighting a descriptiveness refusal — or rebranding after you've already built market awareness around a name you can't protect.
