You found the USPTO search box. You typed in your name. Nothing came up. So you’re good, right?

Not necessarily. And this is important enough that we’re going to take a few minutes to explain exactly why.

Wait, What Happened to TESS

Many of you found this page looking for the USPTO TESS system. However, the USPTO retired TESS in late 2023 and replaced it with a new search tool that is just called “trademark search”.

The key differences between the old TESS and the new Trademark Search system according to the USPTO include:
  • Search Syntax and Structure: TESS used an older “tagged” search system. The new system uses a, “code” structure, where codes must be capitalized and precede the search term and, well, there is a learning curve.
  • Interface and Usability: The new system is designed to be more user-friendly, offering “Basic” and “Advanced” search options on one platform rather than the separate, complex forms in TESS.
  • Performance: Being cloud-based, the new system is generally faster and more stable.
  • Functionality: The new system allows users to better filter results, such as by active or dead marks though it may initially show more, less relevant results, similar to a, “search engine” approach.

    So all in all, the name changed and it’s a little easier to use, but the core issues are exactly the same. 

USPTO Trademark Search

The USPTO has a free online database of federally registered trademarks and pending federal applications and I encourage you to use it. You can find it at: USPTO Trademark Search Page

But, that’s it. ONE database. Federal records only.

So when you search TESS and get a clean result, here’s what that actually means: the federal government checked its own records and didn’t find a conflict. That’s all it means. Nothing more.

Does the government check state trademark registrations when they run that search?

NOPE.

Does the government check common law usage, meaning businesses that have been using a name for years but never registered it anywhere?

NOPE.

The government’s official position is pretty direct. Believe it or not, they basically say:

“It’s not our problem to look around. That’s your job.”

And they mean it.

What TESS Does NOT Search

Here is exactly what a simple TESS search misses, and why each one matters.

Variations and Similar-Sounding Marks

Let’s start with the federal database I just suggested you use. TESS is a search engine but unlike google it doesn’t try to help you with variations and sound alikes etc. If you search for “BlueSky,” it will find “BlueSky.” It will not automatically flag “Blue Skye,” “Blueskie,” or “BLU SKY” as potential conflicts without you understanding a pretty complicated series of codes and search parameters (even though a trademark examiner absolutely would). Catching those requires knowing how to structure a proper search, not just typing your name into a box.

The standard the courts use is “likelihood of confusion to the general public.” The law is not stupid, and adding “the”, making something a plural,or just changing the spelling is NOT going to help you. If it might confuse people that your business is the same as another business, it is a problem.

State Trademark Registrations

Every U.S. state has its own trademark registration system. A business that registered its name in California, Texas, New York, or any of the other 47 states has real, enforceable legal rights — even if they never filed a single thing with the USPTO. TESS shows you none of them. There are 50 states. That is 50 separate registration databases TESS ignores completely even though state trademarks are important reminders that a company might also have common law rights.

Common Law Trademark Rights

This is the one that surprises people most, and it is the biggest source of problems we see.

In the United States, you do NOT have to register a trademark to own one.

The true owner of a trademark is whoever used that name FIRST in inter-state commerce. Not whoever registered it first. Just doing business with a name technically gives you rights to that name.

This means there are businesses all over the country using names they have never registered anywhere, and they have real legal rights to those names. They don’t show up in TESS. They don’t show up anywhere in a federal search. But they are out there, and if you step on one of them, they can come after you. Even after you’ve received a federal trademark registration.

Why This Actually Matters

Here’s the nightmare scenario nobody thinks about until it’s too late.

You search TESS. Clean result. You file for a federal trademark. The government approves it. You spend the next two years building your brand — signage, website, marketing, maybe product packaging with your name on it.

Then you get a cease-and-desist letter from a company in another state. They have been using that name for eight years. They never registered it anywhere. They do not show up in TESS. But they were there FIRST, they can prove it, and now they want you to stop. It certainly gets much more complicated than that and you can read all about it on our “how to read your trademark search report” page, BUT REMEMBER:

Anyone can sue anyone in this Country. It costs a lot of money to defend a lawsuit.

It becomes a situation of “whose lawyer can beat up whose lawyer”. Even if you are right and you would win, you have to be able to afford to fight it. Why would you want to take that chance when you don’t have to?

What a Comprehensive Search Actually Covers

Many years ago, attorneys got together and agreed on what “due diligence” looks like for trademark searching. They called it a Full and Comprehensive Trademark Search, and it covers all the ground TESS leaves open. Creative Trademark Services has been doing this “full search” for attorneys since 1997 and it contains:

Federal — Not just registered marks, but applied-for, abandoned, expired, and cancelled marks. The full picture.

State — All 50 states and US territories. Every registration database TESS ignores.

Common Law — Business directories, domain names, internet presence, trade publications. A real attempt to find people who are using a name and own it under the law but have never registered it anywhere.

That third category is the one that gets people. It is also the reason attorneys have done comprehensive searches as standard practice for decades so they could point to that document and say “We did our industry standard due diligence, and you didn’t show up anywhere”.

So What Should You Do With TESS/USPTO Trademark Search?

Use it. It’s free and it takes 30 seconds. If someone already has your exact name registered federally, you will know right away and you can rethink things before you’ve spent any money. Even fool around with the various search parameters if you are brave, the more you know the better.

But a clean TESS result is not a green light. It is a first pass. The businesses that get into trouble are not the ones who ignored TESS. They’re the ones who stopped there.
