You have the name, the logo, the domain, and maybe a launch date. The last thing you want is a cease and desist letter a month after going live, forcing a rebrand of your website, packaging, and app listing. Yet that is exactly what happens when a trademark search is rushed or skipped. Most founders do check something before launch. The problem is what they check, and what they leave out. This guide explains what a proper trademark clearance search covers, the blind spots that catch startups out, and what to do if you find a conflict. If you want a professional search or opinion, our intellectual property lawyers and Find an Expert service connect you with vetted trademark attorneys.
Key facts: The USPTO federal database does not include unregistered common law marks or state trademark registrations. The USPTO assesses likelihood of confusion across related goods and services, not just your chosen class. There are 45 Nice classes, 34 for goods and 11 for services. A U.S. application filed today waits an average of 4.3 months for a first examination, according to USPTO data from October 2026.
Why a Trademark Search Matters Before Launch
A trademark identifies the source of your goods or services. If your brand name is confusingly similar to an existing mark used for related products, the earlier owner can oppose your trademark application, block your registration, or sue for infringement. Even if you win, the legal fees and lost momentum can be serious for an early-stage business.
A pre-launch search also tests whether your brand is registrable at all. Names that simply describe your product are often refused registration, regardless of whether anyone else is using them. Finding that out after you have printed packaging or raised money on the brand is expensive.
Knockout Search vs Comprehensive Clearance Search
Not all trademark searches are the same. Most founders run a quick knockout search and stop there.
| Feature | Knockout Search | Comprehensive Clearance Search |
| Purpose | Rule out obvious conflicts fast | Assess real risk before investing in the brand |
| Sources | USPTO database, quick web search | Federal and state registers, common law use, domains, international databases |
| Mark variations | Mostly exact or near matches | Phonetic, visual, translated, and conceptual similarities |
| Who runs it | Founder or attorney | Search firm report reviewed by a trademark attorney |
| Output | Go or no-go on obvious conflicts | Written risk opinion and filing strategy |
A knockout search is a sensible first filter for shortlisting names. A comprehensive search is what you rely on before committing real money to a launch.
What Most Founders Miss in a Trademark Search
1. Searching Only for Exact Matches
The legal test is likelihood of confusion, not identical spelling. Examiners compare marks in sound, appearance, meaning, and overall commercial impression. KWIK and QUICK can conflict. So can a word and its translation under the doctrine of foreign equivalents. Search for spelling variations, plurals, phonetic equivalents, and synonyms.
2. Searching Only One Class
Founders often search their own Nice class and assume they are clear. The USPTO considers whether goods and services are related, even across different classes. A clothing brand can conflict with a mark for bags or footwear, and a software mark can conflict with one for online services.
3. Ignoring Unregistered Common Law Rights
In the United States, a business gains common law trademark rights simply by using a mark in commerce, usually limited to its geographic area of use. The UK protects unregistered marks through the law of passing off. Neither will appear in the federal database. Search Google, Amazon, app stores, social media platforms, industry directories, and state business filings.
4. Overlooking Pending Applications and State Registrations
A pending application with an earlier filing date can block your mark even though it has not registered yet. Once registered, a federal filing date generally gives nationwide priority from the day it was filed. State trademark registrations, which the USPTO does not track, add another layer to check.
5. Treating a Company Name or Domain as Brand Protection
Registering a company name with your Secretary of State or Companies House, or buying a domain, does not give you trademark rights. It also does not stop you from infringing someone else’s mark. These checks are useful, but they are not a clearance search.
6. Forgetting Famous Marks
Famous brands receive broader protection that can reach unrelated goods. Any name that echoes a household brand carries extra risk, as explained in our guide to trademark dilution and famous marks.
7. Searching Only Your Home Market
Many countries, including China and those using the EU trade mark system, award rights mainly on registration rather than use. If you plan to sell or manufacture abroad, check those registers early. Under the Paris Convention, you generally have six months from your first filing to claim the same priority date in other member countries.
8. Skipping the Logo and Design Elements
Logos need their own search. The USPTO uses design search codes to classify images such as stars, animals, or shields, and a similar device mark can cause a conflict even when the words differ.
How to Run a Trademark Search Before Launch
Step 1: Define Your Goods and Services
List exactly what you sell now and plan to sell soon, using wording from the USPTO Trademark ID Manual. Your description drives which marks are relevant.
Step 2: Run a Knockout Search
Start with the USPTO’s free Trademark Search system, which replaced the old TESS database on November 30, 2023. The USPTO search guidance explains how to search by word, design code, and coordinated classes.
Step 3: Check Common Law and International Sources
Search the web, marketplaces, social media handles, domain names, and state databases, then check international tools for key markets.
| Search Tool | What It Covers | Key Limitation |
| USPTO Trademark Search | U.S. federal registrations and pending applications | No common law or state marks |
| State trademark databases | State-level registrations | Each state searched separately |
| WIPO Global Brand Database | Marks from many national and international registers | Coverage varies by country |
| EUIPO TMview | EU and participating national offices | Does not show unregistered use |
| UK IPO trade mark search | UK registered marks | Passing off rights not shown |
| Web, marketplaces, social media | Unregistered common law use | Hard to search thoroughly by hand |
Step 4: Get a Professional Search and Opinion
For a brand you will invest in, commission a comprehensive search report and have a trademark attorney interpret it. Raw search results are easy to misread without experience of how examiners and courts assess confusion.
Step 5: File Quickly
Once cleared, file without delay. In the U.S., an intent-to-use application lets you secure a filing date before launch. The base federal fee is $350 per class, with surcharges of $100 for insufficient information and $200 for free-form descriptions. For timelines, see how long it takes to register a trademark in the United States.
What to Do If Your Search Finds a Conflict
A conflict does not always mean starting over. Depending on the facts, you can adjust the name or logo, narrow your goods and services, or approach the owner about a coexistence or consent agreement or even buying the mark. If the conflicting registration is not actually in use, the Trademark Modernization Act of 2020 created expungement and reexamination proceedings to remove unused marks, with a USPTO fee of $400 per class. A trademark attorney can tell you which option is realistic before you spend money on any of them.
Why Founders Work With a Trademark Attorney
Your brand is often one of the first assets investors and buyers examine during due diligence, and a weak or contested mark can reduce its value, as covered in our article on what happens to IP rights when you sell a business. A trademark attorney helps you choose a stronger mark, interpret search results, draft a precise application, and plan international protection.

Frequently Asked Questions
Is a USPTO database search enough before launch?
No. It misses common law users and state registrations, which can still stop you from using your brand.
Does registering my company name or domain protect my brand?
No. Company and domain registrations do not create trademark rights or prevent infringement claims.
When should I run a trademark search?
At the naming stage, before you invest in logos, packaging, domains, or marketing.
Can I use a name if nobody has registered it?
Not always. An unregistered business using the name may hold common law rights in its area.
Should I file a trademark application before launching?
Usually, yes. A U.S. intent-to-use application secures your filing date before you start selling.
How much does a trademark search cost?
A USPTO database search is free. Professional comprehensive searches and attorney opinions cost more and vary by provider and scope.
