Why MUSIC.AI’s Trademark Failed: Descriptive Marks, TTAB Risk, and Branding Strategies for AI and Technology Companies

By: Moish E. Peltz, Esq. 

In the fast-moving worlds of artificial intelligence, speed to market often trumps careful branding strategy. Founders frequently choose names that describe exactly what their product does. While these names are great for explaining a product to investors, they are often disastrous for trademark protection.

A recent decision by the Trademark Trial and Appeal Board (TTAB), In re Moises Systems, Inc., offers a stark warning to tech companies. The Board affirmed the refusal to register the mark MUSIC.AI, finding it merely descriptive of the underlying software.

For founders and in-house counsel in the AI and blockchain sectors, this case is a critical reminder: if your name merely describes your function, you likely cannot own it.

What the TTAB Decided in the MUSIC.AI Case

Moises Systems sought to register the mark MUSIC.AI for downloadable and non-downloadable software modules used for audio source separation, mixing, and mastering. The U.S. Patent and Trademark Office (USPTO) refused registration under Section 2(e)(1) of the Trademark Act, arguing the mark was “merely descriptive”.

The Board’s analysis was straightforward and instructive:

• “MUSIC” is Descriptive: The software was explicitly designed to create and modify "music, songs, sounds, and audio recordings". Therefore, the term immediately conveys a key feature of the goods.
• “AI” is Descriptive: The Board noted that “AI” is a recognized abbreviation for “artificial intelligence,” defined as software designed to imitate intelligent human behavior. Because the applicant’s software uses AI to function, the term simply describes the technology powering the product.
• The Combination Failed: Putting two descriptive terms together (MUSIC + AI) did not create a new, distinctive meaning. The Board found that the composite term “MUSIC.AI” conveyed nothing more than “software using artificial intelligence for music applications”.

Why Descriptive Trademarks Fail in AI

Trademark law operates on a spectrum of distinctiveness. “Arbitrary” marks (like Apple for computers) and “Suggestive” marks (like Netflix for internet flicks) are strong and protectable. “Descriptive” marks, however, are relatively weaker because they merely describe a quality, feature, or function of the goods.

In the MUSIC.AI case, the Board emphasized that a term is merely descriptive if it “immediately conveys knowledge of a quality... of the goods”. The Board also relied on evidence that showed that competitors like “Soundraw” and “Loudly” already use phrases like “AI Music Generator” and “AI Music Creation” to describe their products.

For AI startups, terms like “Token,” “Bot,” “Neural,” and “Data” function similarly. If your competitors need these words to describe their own products, the USPTO is unlikely to grant you a monopoly over them.

Why ".AI" and Domain-Style Marks Usually Don’t Save You

A common misconception among tech founders is that adding a “.AI” domain extension makes a generic name unique. The MUSIC.AI decision explicitly rejected this strategy.

The applicant argued that the “dot” (period) between MUSIC and AI created a unique commercial impression. The Board disagreed, citing precedent that punctuation generally does not alter the commercial impression of a word mark.

Furthermore, the Board rejected the argument that using the Top-Level Domain (TLD) syntax made the mark distinctive. The decision noted that “having a top-level domain as part of the mark does not preclude the mark being merely descriptive”. The Board pointed to numerous Supplemental Register registrations for marks like TOOL.AI, DATA.AI, and COMMERCE.AI, which were all treated as descriptive.

Common Trademark Pitfalls for AI & Blockchain Startups

The MUSIC.AI ruling highlights several pitfalls specific to emerging tech companies:

• Naming the Product What It Is: The applicant’s own website described the product as “The Industry’s most extensive collection of state-of-the-art music APIs and AI audio solutions”. When your marketing copy uses the trademark to describe the product category, you are giving the USPTO ammunition to refuse your application.
• Relying on “First Mover” Status: The applicant argued that no third party was using the exact styling “MUSIC.AI” (with the dot). The Board clarified that being the first to use a descriptive term doesn't give you the right to register it.
• Ignoring Industry Context: The Board relied heavily on third-party websites (e.g., Remusic, Soundraw) to show that “Music AI” is a common industry term. If your industry uses a phrase to describe a category, it’s extremely difficult to claim it as a brand.

How AI Companies Can Build Distinctive, Protectable Brands

To avoid the fate of MUSIC.AI, a company’s naming strategy should rely on “suggestive” or “arbitrary” trademarks.

• The "Suggestive" Sweet Spot: Choose a name that requires a mental leap.
• Layered Brand Architecture: If you must use a descriptive name for SEO purposes (e.g., “CryptoTaxHelper”), pair it with a strong, distinctive house mark (e.g., “TurboTax” is the house mark; “Tax Helper” is descriptive).
• The Supplemental Register: If you are stuck with a descriptive name, you may be able to register it on the Supplemental Register (as seen with BASE64.AI and ZEROTRUSTED.AI). This offers some protection but is weaker than the Principal Register.

Practical Takeaways for Founders and In-House Counsel

• Check the Dictionary and the Market: If your proposed name appears in the dictionary definitions of your product’s features (like “Music” and “AI”), it is likely descriptive.
• Punctuation is Not Magic: Using a domain name, or adding a dot, a slash, or a hash tag rarely transforms a descriptive word into a protectable trademark.
• Audit Your Marketing: Ensure your marketing team isn't using your potential trademark on your own website or marketing materials as a noun to describe the product category.

Conclusion

The MUSIC.AI decision is not an outlier; it is a textbook application of trademark law to new technology. As the Board noted, while the technology may be novel, the “quickness with which changing nomenclature is introduced... is brisk,” and the USPTO must ensure these terms remain available for all competitors to use.

For AI and other technology companies, the lesson is clear: distinctiveness is a business asset. By selecting a unique brand name early, you avoid costly legal battles and build a stronger, more defensible position in the marketplace.
