Trademark Registration: USPTO Application Process, Search Strategy, and Protection
Your brand is worth more than your building. When customers see your logo, they associate it with a certain quality, reliability, and experience. That association is an asset worth protecting. Yet thousands of businesses operate for years without registering their trademarks, leaving their brand identity vulnerable to copycats and infringers who can erode the goodwill built over decades.
The United States Patent and Trademark Office (USPTO) registered over 400,000 trademarks in 2024, and the number of pending applications continues to grow. Trademark registration provides nationwide priority, the right to use the registered symbol, the ability to sue in federal court, and incontestable status after five years. Trademark law is governed by the Lanham Act of 1946 (15 U.S.C. Sections 1051-1141n), which balances the protection of brand owners against the need for competition and free expression.
Trademark Search Strategy
Preliminary Knockout Search
Before filing an application, conduct a preliminary search to identify obvious conflicts. The USPTO maintains the Trademark Electronic Search System (TESS), a free database of pending and registered marks. Search for identical marks and phonetic equivalents in the same class of goods or services. A preliminary search is not comprehensive but can identify obvious bars to registration early.
Comprehensive Availability Search
A comprehensive search covers federal registrations, state registrations, common law uses, business name databases, domain name registrations, and social media handles. Professional trademark search firms use proprietary databases that uncover conflicting marks that a TESS search would miss. The USPTO examining attorney will conduct a full search during examination, but discovering an conflict after filing wastes the application fee.
International Class System
The Nice Classification system divides goods and services into 45 classes. Classes 1-34 cover goods, and classes 35-45 cover services. Each class requires a separate filing fee. Selecting the correct class is critical—describing goods in the wrong class can result in rejection. The USPTO accepts applications for multiple classes in a single application, with each additional class adding to the filing fee.
USPTO Application Process
Application Filing
The USPTO accepts applications through the Trademark Electronic Application System (TEAS). Applicants can file under Section 1(a) (use in commerce), Section 1(b) (intent to use), or Section 44 (foreign registration). Use-based applications must include a specimen showing the mark on goods or in connection with services. Intent-to-use applications require a statement of use and additional fee before registration.
Examination
A USPTO examining attorney reviews the application for compliance with the Lanham Act. Common refusals include likelihood of confusion with a prior mark (Section 2(d)), mere descriptiveness (Section 2(e)(1)), and failure to function as a trademark. The examining attorney issues an Office Action detailing any refusals or requirements. Applicants have six months to respond or the application is abandoned.
Publication and Opposition
If the examining attorney approves the application, it publishes in the Trademark Official Gazette for a 30-day opposition period. Third parties may oppose registration by filing a Notice of Opposition with the Trademark Trial and Appeal Board (TTAB). Opposition proceedings resemble federal litigation with discovery, motions, and trial. Approximately 3% of published marks face opposition.
Registration and Maintenance
After publication and any opposition proceedings, the USPTO issues a registration certificate. The registrant must file a Section 8 declaration of continued use between the fifth and sixth year after registration, with a grace period through the sixth year. Section 15 declarations of incontestability can be filed after five years of continuous use. Renewal filings under Section 9 are due every ten years. See our intellectual property basics guide for the full IP lifecycle.
Enforcement and Litigation
Trademark Infringement
Trademark infringement under Section 32 of the Lanham Act requires proof that the defendant used a mark in commerce without consent and that the use is likely to cause confusion. Courts evaluate the Polaroid factors (named after Polaroid Corp. v. Polarad Electronics Corp., 1961): strength of the mark, proximity of the goods, similarity of the marks, evidence of actual confusion, marketing channels used, degree of purchaser care, defendant’s intent, and likelihood of expansion.
Dilution
The Trademark Dilution Revision Act of 2006 protects famous marks against dilution by blurring or tarnishment. Dilution by blurring weakens the unique association between a famous mark and its goods. Dilution by tarnishment harms the reputation of a famous mark through negative associations. Dilution claims do not require likelihood of confusion—a mark qualifies if it is widely recognized by the general consuming public.
Counterfeiting
Counterfeit marks are spurious marks identical or substantially indistinguishable from registered marks. The Trademark Counterfeiting Act of 1984 established criminal penalties for trafficking in counterfeit goods. Civil remedies include treble damages, attorneys’ fees, and ex parte seizure orders. Customs and Border Protection seizes millions of dollars worth of counterfeit goods annually under the authority of the Tariff Act of 1930.
International Trademark Protection
Madrid Protocol
The Madrid Protocol, implemented in the United States through the Madrid Protocol Implementation Act, allows trademark owners to file a single international application designating multiple member countries. The International Bureau of the World Intellectual Property Organization (WIPO) examines the application formally, while each designated country examines substantively. The Madrid Protocol covers over 130 countries.
National Filings
Some countries, including Canada, China, and Brazil, require national filings despite Madrid Protocol membership. Each country applies its own examination standards and opposition procedures. China follows a first-to-file system, making early registration critical. The European Union Intellectual Property Office handles EU-wide trademark registration through the European Union Trademark (EUTM) system.
Common Law Trademark Rights
Trademark rights arise from use in commerce, not from registration. Common law trademark rights, indicated by the TM symbol, belong to the first user of a mark in a particular geographic area. These rights are established through actual use—displaying the mark on goods, in advertising, and in connection with services. Common law rights are limited to the geographic area where the mark is actually used and the market area where expansion is reasonably anticipated.
Establishing common law rights requires evidence of the mark’s use, including sales records, advertising materials, packaging, and customer testimony. The geographic scope of common law rights depends on the extent of the mark’s reputation and market penetration. While federal registration provides nationwide priority, the prior user of an unregistered mark may retain rights in its established geographic area even against a subsequent federal registrant.
Trademark Maintenance and Renewal
Trademark registration requires ongoing maintenance to remain enforceable. Between the fifth and sixth year after registration, the registrant must file a Section 8 declaration of continued use with a specimen showing the mark in commerce. Between the ninth and tenth year after registration, and every ten years thereafter, the registrant must file combined Section 8 and Section 9 renewal applications. The USPTO provides a six-month grace period for late filings with an additional fee. Failure to file results in cancellation of the registration.
Trademark monitoring services track new applications and registrations that may conflict with existing marks. Watching services alert trademark owners to potentially infringing applications, allowing them to file oppositions or take other action. Trademark owners should monitor marketplace use, domain name registrations, and social media platforms for unauthorized use of their marks. Diligent enforcement prevents marks from becoming generic—a risk that claimed the trademarks for aspirin, escalator, and thermos.
Trademark Litigation
Trademark infringement litigation typically begins with a cease-and-desist letter and demand for the infringer to stop using the mark. If the dispute is not resolved, the trademark owner may seek a preliminary injunction to halt the infringing use pending trial. Courts evaluate the likelihood of success on the merits, irreparable harm, balance of equities, and public interest. The Trademark Counterfeiting Act provides for seizure orders that allow trademark owners to confiscate counterfeit goods without advance notice to the infringer.
The Trademark Trial and Appeal Board (TTAB) handles oppositions to registration and cancellation proceedings. TTAB proceedings are less expensive than federal court litigation and allow trademark owners to challenge confusingly similar marks before they proceed to registration. Governmental immunity from trademark infringement claims under the Lanham Act was affirmed by the Supreme Court in Allen v. Cooper (2020), though the case addressed copyright rather than trademark. Federal venues for trademark litigation include any district where the defendant is subject to personal jurisdiction.
Frequently Asked Questions
How long does trademark registration take? The USPTO examination process typically takes 12 to 18 months from filing to registration. Simple applications without office actions may register in 8 to 10 months. Applications facing refusals, oppositions, or extensions can take 24 to 36 months.
What is the difference between TM and registered symbols? The TM symbol may be used with any mark to claim common law rights. The registered symbol may only be used after USPTO registration. Improper use of the registered symbol with an unregistered mark can constitute fraud on the USPTO and grounds for cancellation.
Can I trademark a business name that is already in use? If another business in a related industry uses the same name, registration will be refused due to likelihood of confusion. If the existing use is in an unrelated industry, registration may be possible. A comprehensive search is essential to identify conflicts before filing.
What happens if someone opposes my trademark? You may negotiate a settlement, file a response to the opposition, or abandon the application and refile with modified goods or services. The TTAB encourages settlement through mediation. If settlement is impossible, the opposition proceeds to trial before the TTAB.
