In Short
Trademark rights in the United States come from using a mark, not from registering it, but registration adds important advantages. Whether a mark can be enforced depends on how distinctive it is, who used it first and where, and whether the owner has kept the rights alive. Trade dress, the look of a product or its packaging, can also be protected, but product designs require proof that buyers associate the design with one source.
Common situations.
- A business has used its name for years but never registered it.
- A competitor argues the mark is merely descriptive and cannot be owned.
- Two companies used similar names in different cities before either registered.
- A company claims trade dress rights in the shape of its product.
Sources of rights.
| Source | Scope | Key advantages |
|---|---|---|
| Federal registration (Lanham Act) | Nationwide, subject to prior users | Evidence of validity and ownership (15 U.S.C. §§ 1057(b), 1115(a)); nationwide notice (§ 1072); nationwide priority from the filing date (§ 1057(c)); possible incontestability (§ 1065); statutory damages for counterfeits; recordation with Customs |
| Texas registration | Texas | Claims under Tex. Bus. & Com. Code §§ 16.102-16.104 |
| Common-law use | The area where the mark is used and known | Protected against confusing uses under § 1125(a) and Texas common law |
Distinctiveness.
Marks fall along a spectrum (Zatarains, Inc. v. Oak Grove Smokehouse, Inc., 698 F.2d 786 (5th Cir. 1983)):
| Category | Example idea | Protectable? |
|---|---|---|
| Generic | The common name for the product | Never |
| Descriptive | Describes a quality or feature | Only with secondary meaning |
| Suggestive | Requires imagination to connect to the product | Yes, inherently distinctive |
| Arbitrary | A common word used for an unrelated product | Yes, inherently distinctive |
| Fanciful | An invented word | Yes, the strongest |
Secondary meaning. A descriptive mark is protected only once buyers associate it primarily with a single source. The Fifth Circuit considers the length and manner of use, sales volume, the amount and manner of advertising, media coverage, consumer surveys, direct consumer testimony, and the defendant's intent in copying (Amazing Spaces, Inc. v. Metro Mini Storage, 608 F.3d 225 (5th Cir. 2010)).
Generic.com terms. A term formed from a generic word plus ".com" is not automatically generic; the question is how consumers understand it (U.S. Patent & Trademark Office v. Booking.com B.V., 591 U.S. 549 (2020)).
Presumptions and incontestability.
A registration on the Principal Register is evidence of the mark's validity and the registrant's ownership and exclusive right to use it (§§ 1057(b), 1115(a)). After five years of continuous use following registration, the owner may file a declaration making the right to use the mark incontestable (§ 1065). An incontestable registration is conclusive evidence of the right to use, subject to listed defenses (§ 1115(b)), and cannot be challenged as merely descriptive (Park 'N Fly, Inc. v. Dollar Park & Fly, Inc., 469 U.S. 189 (1985)). It can still be canceled on grounds such as genericness, functionality, abandonment, or fraud (§ 1064(3)).
Priority and territory.
As between users, the first to use a mark in an area generally has superior rights there. A federal registration gives the owner nationwide constructive priority as of the application filing date (§ 1057(c)), but a business that used the mark in a limited area before that date may continue there (§ 1115(b)(5)). Disputes between local businesses with similar names often turn on dated evidence of first use in each market.
Losing rights.
- Abandonment. A mark is abandoned when use is discontinued with intent not to resume. Three consecutive years of nonuse is prima facie evidence of abandonment (§ 1127).
- Genericness. A mark that becomes the common name of the product loses protection and may be canceled at any time (§ 1064(3)).
- Naked licensing. Licensing a mark without controlling the quality of the licensee's goods can result in loss of rights.
Trade dress.
The overall appearance of a product's packaging or a business's décor can be protected if it is distinctive and not functional. Restaurant décor can be inherently distinctive; a Texas case, Two Pesos, Inc. v. Taco Cabana, Inc., 505 U.S. 763 (1992), established that point. But product design is never inherently distinctive and requires proof of secondary meaning (Wal-Mart Stores, Inc. v. Samara Bros., 529 U.S. 205 (2000)). A feature that is essential to the product's use or purpose, or affects its cost or quality, is functional and cannot be protected; an expired utility patent claiming the feature is strong evidence of functionality (TrafFix Devices, Inc. v. Mktg. Displays, Inc., 532 U.S. 23 (2001)). In a suit over unregistered trade dress, the plaintiff must prove it is not functional (§ 1125(a)(3)).
