Even within trademark scholarship, a critique holds that the law hands out rights generously, perhaps too generously. “[I]t is argued that trade marks are granted too readily [and] that the rights granted to trade mark owners are too strong[.]” Trademark Law and Theory 3 (Graeme B. Dinwoodie & Mark D. Janis eds., 2008). That critique sets the stage for a more fundamental question that trips up founders, general practitioners, and even seasoned business lawyers: what exactly is the difference between a trade name and a trademark, and does the distinction actually matter? In everyday speech the two are used interchangeably, and the law itself often treats them that way; however, the overlap is not total, and the gaps between the two concepts are precisely where businesses lose rights, invite litigation, or forfeit the protections that federal registration could have secured. This article works through the authorities, old and new, judicial and scholarly, to map the relationship between the name a business goes by and the mark it uses to sell.
What Trademark Law Actually Protects
Begin with the threshold question of what trademark law actually involves when applied to the name of a business. “When it comes to your business name, trademark law is concerned with the name you use in the marketplace.” Glen Secor, Trademark: Legal Care for Your Brand 30 (14th ed. 2025). Secor’s formulation captures the organizing principle: trademark law does not concern itself with the name on your incorporation papers (or organization papers, if an LLC) for its own sake, but with how that name functions when customers encounter it. The decisive question is use in commerce. A name sitting dormant in a corporate registry is a legal formality; the same name displayed on a storefront, printed on an invoice, or affixed to a product label begins to do the work of a mark, identifying source and distinguishing one company’s goods or services from another’s.
Trade Names and Trademarks Generally Share the Same Rules
A natural follow-up is whether trade names enjoy some separate legal regime, and the authorities are generally in agreement that they do not. “The general principles of trademark law apply to trade names.” Imported Auto Parts Corp. v. R.B. Shaller & Sons, Inc., 258 N.W.2d 797, 799 n.2 (Minn. 1977) (citing 1 McCarthy, Trademarks and Unfair Competition, § 9:1). Courts do not apply a completely separate body of law to trade names. As the Minnesota Supreme Court put it, the same analytical framework governs both. The practical consequence is that a business cannot assume its trade name occupies some protected category immune from the rigors applied to trademarks.
Litigation is where this shared framework is put to the test. “In a suit based on infringement, there is no distinction between the various forms of marks, e.g., a trademark, a service mark, or a business name (trade name).” Moore Bus. Forms, Inc. v. Seidenburg, 619 F. Supp. 1173, 1180 (W.D. La. 1985) (citing R. Callmann, The Law of Unfair Competition Trademarks and Monopolies § 21.08 at 27 (4th ed. 1983)). “While a trade name is not strictly a trade mark, it is generally governed as to its use by the same rules as a trade mark.” Stover v. Farmers’ Educ. & Co-op. Union of Am., 250 F.2d 809, 811 (8th Cir. 1958). Nowhere is this unity clearer than in infringement litigation. When a plaintiff alleges that a defendant has traded on its goodwill, the court need not pause to classify the designation as a trademark, service mark, or trade name before assessing the claim on the merits. The label is largely irrelevant; what matters is whether consumers are likely to be confused.
Why a State Filing Isn’t Enough
Many founders assume that clearing a name with the state secretary’s office secures their rights to it, but the law is unforgiving on this point. “The fact that the New York Secretary of State permitted the use of the words Miss Dior in a corporate name has no bearing on the question of trademark infringement or unfair competition.” Christian Dior, S.A.R.L. v. Miss Dior of Flatbush, Inc., No. 70-C-1471, 1972 U.S. Dist. LEXIS 14652, at *6-7 (E.D.N.Y. Mar. 15, 1972) (citing Colonial Radio Corp. v. Colonial Television Corp., 78 F. Supp. 546, 550, 77 USPQ 650, 653 (S.D.N.Y. 1948)). A corollary follows, and it is one that surprises many business owners: securing a corporate name from a secretary of state confers no trademark rights and provides no defense to infringement. The Miss Dior court made the point bluntly. State incorporation and trademark protection are different systems serving different ends (one authorizes the existence of an entity, the other regulates use in the marketplace) and “clearance” of a name by a state filing office says nothing about whether that name may lawfully be used as a mark. Perhaps a warning in this regard should be prominently displayed by all secretary of state offices. Such a warning is all the more needed in an era in which accountants, online formation services, and other non-lawyers routinely file articles of organization and incorporation, and few of those filers have expertise in trade name and trademark rights.
When a Trade Name Becomes a Trademark
If the governing principles are identical, the practical line to watch is the moment of conversion. “A trade name is a trademark for the name of an entity or business. A trade name can be registered as a federal trademark if the trade name is used as a trademark[.]” Ash Tankha & Lynn Bout, Trademarks – A Guide For Registering, Opposing and Appealing A Mark 2 (2d ed. 2010). If trade names and trademarks are governed by the same principles, when does a trade name actually become a trademark? The answer, as Tankha and Bout explain, turns again on function. A trade name is the public operating name of an entity or business; it crosses into trademark territory the moment it is used to identify and distinguish goods or services, at which point it may be eligible for federal registration.
An Overlap With Deep Historical Roots
This blurring of the two categories is hardly a recent development. “Some of our ablest judges treat the words ‘tradename’ and ‘trademark’ as synonymous.” James Love Hopkins, The Law of Trademarks Tradenames and Unfair Competition 10 (3d ed. 1917) (citing Thomas G. Plant Co. v. May Co., 44 C. C. A. 534; 105 Fed. Rep. 375). “[A] trade name may also be used as a trademark, or may substantially overlap with a trademark, such that the two may be nearly indistinguishable.” Lavanty v. Nicolinni’s Ristorante I & II, LLC, 2015-Ohio-5435, ¶ 13, 55 N.E.3d 565, 570 (Ohio Ct. App. 2015). Albeit confusing, this functional overlap has been consistent. More than a century ago, commentators observed that judges treated the two terms as synonymous, and courts have long recognized that a single designation can serve double duty, operating as both the name of the business and the mark on its goods until the two are, as the Lavanty court said, nearly indistinguishable. The vocabulary has been fluid for generations precisely because the underlying commercial reality is fluid.
Trade Name Protection Under Kansas Law
None of this means the labels are interchangeable in every respect. A trademark relates chiefly to the thing sold, and a trade name “involves also the individuality of the maker, for protection in trade, to avoid confusion in business, and to secure the advantages of a good reputation.” Harryman v. Harryman, 93 Kan. 223, 228 (Kan. 1914). “It is said that a trade name, therefore, has a broader scope than a trade-mark.” Id. For Kansas businesses, this principle is more than a historical footnote. Harryman remains a Kansas Supreme Court decision on the protection of business names, and its recognition that a trade name safeguards the “individuality of the maker” and the “advantages of a good reputation” continues to inform how Kansas courts think about unfair competition and trade-name disputes. Businesses organized or operating in Kansas typically register their entity with the Kansas Secretary of State, but (as the Miss Dior line of cases warned above) that filing secures only the right to use the name as the entity’s registered name within the corporate registry; it does not, by itself, confer enforceable trademark rights or immunize the user from an infringement claim. A Kansas company that wants to protect the name customers associate with its goods or services should treat the name as an asset: clear it against federal and state records, consider registration with the United States Patent and Trademark Office where the name functions as a mark, and preserve evidence of its use in commerce throughout Kansas and beyond.
How the Distinction Dissolves in Practice
In the ordinary life of a business, the theoretical boundary between the two tends to dissolve. “Companies frequently use their trade names as trademarks or service marks for their products and services–that is, as designators of origin in their advertising and on the products.” Richard Stim, Patent, Copyright & Trademark 532 (18th ed. 2024). “In some cases a company name, its trade name, and its trademark are the same.” Benedikt Sas, Philippe Jacobs & Stanislas de Vocht, Intellectual Property and Assessing its Financial Value 63 (2014). “It is true that some trade names if affixed or attached to goods and used as trademarks may become trademarks.” Modern American Law 481 (Eugene Allen Gilmore & William Charles Wermuth eds., 1915). In practice, the two concepts collapse into one far more often than the textbook distinction suggests. Companies routinely deploy their trade names as source identifiers in advertising and on their products; in many businesses the company name, the trade name, and the trademark are literally the same words, plus or minus an entity designator. The legal question is rarely which box the name belongs in and almost always whether the name, as used, is doing a trademark’s job.
What This Means for Your Business
These distinctions are far from academic; they shape how competent counsel should guide a new venture. “Most attorneys assisting in business start-ups fail, however, to appreciate that the business’ name may be a trademark that must be searched at the federal level, and fail to advise regarding the benefits of registering the name with the United States Patent and Trademark Office (PTO).” Maria Crimi Speth, It’s All in the Name Intellectual Property Issues to Consider in a Business Start-Up, 33 AZ Attorney 24, 24 (1996). “A small business may or may not have trade secrets, copyrights, or patents, but invariably it will have trademarks or tradenames.” William Lynch Schaller, Growing Pains: Intellectual Property Considerations for Illinois Small Businesses Seeking To Expand, 35 Loy. U. Chi. L.J. 845, 920 (2004). Why does any of this matter beyond the CLE seminar room? The gap between formal distinction and functional reality is where businesses get hurt. Too many advisors treat the choice of a business name as a corporate-formation task rather than an intellectual-property decision, overlooking the need to clear the name at the federal level and the advantages of registering it with the USPTO. The oversight is costly precisely because, whatever else a small business may lack, it will almost always own trademarks or trade names. The lesson for counsel is straightforward. Stop asking whether a name is a “trade name” or a “trademark” as though the categories were mutually exclusive, and start asking how the name is used in the marketplace. If it identifies the source of goods or services, it is functioning as a mark, and it deserves to be searched, cleared, and, where warranted, registered with the same care as any other asset of the business. Treat the name as the valuable property it is, and the doctrinal labels largely take care of themselves.
