Your Business Has Used Its Name for Years. But Can You Prove It?

Imagine building a business around a particular name for ten years. Customers know it, suppliers recognize it, and you’ve invested considerable time developing its reputation. Then another company files a trademark application for a similar name, and you find yourself questioning whether your earlier use gives you the right to challenge it.

You know when your business started. You remember your first customers. You might even remember the first product you sold under the name.

But when you start looking for the paperwork, things become complicated.

The invoices are gone. Your original website was replaced years ago. The employee who managed your early sales records no longer works for you.

This is where many trademark owners discover something important about litigation before the Trademark Trial and Appeal Board (TTAB). Having used a trademark for years and being able to establish that use through admissible evidence are two different things.

The good news is that missing records do not necessarily prevent a business from proving earlier trademark rights.

Why Does the TTAB Care About Who Used a Trademark First?

Trademark disputes frequently involve two businesses claiming rights in similar names. When those claims overlap, the Board may need to determine which party has priority.

Priority generally concerns which party acquired legally recognized trademark rights first.

For example, suppose a Massachusetts company began selling skincare products under a particular brand in 2017. Another business subsequently files a federal trademark application for a confusingly similar name covering related products.

Depending on the circumstances, the earlier business may have grounds to oppose the application based on its prior common law trademark rights.

However, the earlier company cannot simply tell the Board that it has been operating since 2017 and expect that statement to resolve the dispute.

It must establish the facts necessary to support its claim.

Importantly, the relevant priority date may involve more than the parties’ claimed first sales. Federal application filing dates, constructive use rights, existing registrations, and the nature of the pleaded claims can affect the analysis.

This is why a trademark priority dispute should begin with identifying exactly which rights each party is asserting.

What If Your Business Never Kept Detailed Records?

Not every company begins with an accounting department, a formal document retention policy, or an organized archive of its earliest transactions.

Many businesses start with a founder, a small customer base, and a product or service they believe in.

During those early years, preserving evidence for a future trademark dispute is rarely a priority.

Fortunately, the TTAB does not automatically reject an earlier-use claim simply because the trademark owner cannot produce every original invoice.

The Board evaluates the evidence properly introduced into the proceeding and determines whether the party has satisfied the applicable burden of proof.

That evidence may include firsthand testimony and other materials capable of establishing when the trademark was actually used.

The important distinction is that the evidence must demonstrate trademark use, not merely the existence of the business.

A company might have incorporated in 2016 but only started selling products under its disputed trademark in 2019. Those dates represent different legal events.

Can a Business Owner’s Testimony Establish Trademark Priority?

This is one of the more interesting aspects of TTAB litigation.

A business owner’s testimony can potentially establish earlier trademark use, even when supporting documentation is limited.

But there is a meaningful difference between explaining a company’s history and providing testimony that establishes legally relevant facts.

Consider two statements.

The first is straightforward: “I’ve been using this trademark since 2016.”

The second explains that the owner began selling a particular product under the mark in 2016, describes how the mark appeared on the packaging, identifies the customers or distribution channels involved, and explains the basis for remembering those events.

The second account provides considerably more information for the Board to evaluate.

The Federal Circuit has recognized that sufficiently clear, convincing, consistent, and uncontradicted oral testimony can establish trademark priority. The credibility and detail of that testimony remain important.

For a business owner, this means firsthand knowledge may be valuable, but confidence alone is not a substitute for a reliable account of actual trademark use.

Could Old Photographs, Emails, or Advertising Materials Help?

Sometimes the most useful evidence is found somewhere other than the company’s accounting system.

An old photograph might show branded products displayed at a trade show. An email exchange could reference a customer order. A former distributor may have retained a catalog showing the mark on goods sold years earlier.

Even an outdated website can help explain how the business presented its products or services to customers.

However, these materials must be evaluated carefully.

A photograph showing a branded product does not necessarily establish that the product was sold in commerce on the date the photograph was taken.

Similarly, an advertisement announcing an upcoming launch may demonstrate preparation for business activity without establishing completed trademark use.

This distinction matters because trademark rights generally depend on qualifying use of the mark, subject to applicable statutory rules and constructive priority provisions.

The strongest evidence connects the trademark to identifiable commercial activity during the relevant period.

What Happens When the Available Evidence Tells Different Stories?

Business records are not always consistent, particularly when they were created years apart.

Suppose a founder recalls launching a product in 2017. Yet an archived company webpage from 2019 describes that product as a new addition to the business.

Does that mean the founder’s testimony is necessarily false?

No. There may be an explanation. Perhaps the company introduced an updated product in 2019 or expanded into a new market.

But the inconsistency deserves attention.

The Board must evaluate the reliability of the evidence before it. When testimony and documents appear to conflict, a party may need to explain why both accounts can be reconciled.

This is one reason trademark litigation should not involve selecting the earliest imaginable date and building a story around it.

A more credible approach is to determine what the available evidence actually establishes, even when that date is later than the business owner initially remembered.

Can Common Law Trademark Rights Survive Without a Federal Registration?

Yes. Federal registration is not the only possible source of trademark rights in the United States.

A business may acquire common law trademark rights through qualifying use of a distinctive mark in connection with its goods or services.

Those rights can become relevant in TTAB opposition and cancellation proceedings.

However, the scope of common law rights depends on the particular circumstances. Earlier use does not automatically establish unrestricted nationwide rights, nor does it necessarily defeat every later trademark application.

The party asserting those rights must establish the relevant elements of its claim, including priority where required.

For businesses operating for years without registration, understanding these limitations is especially important.

A longstanding brand may have meaningful legal protection, but the strength of that protection depends on the facts.

Why Reconstructing Your Trademark History Matters

When records are missing, the objective should not be to recreate paperwork that no longer exists.

Instead, the business should work toward developing an accurate history of its trademark use.

That process may reveal important distinctions between when the company was formed, when the brand name was selected, when advertising began, and when goods were first sold or services were actually rendered under the mark.

Those events can occur months or even years apart.

A company might have purchased a domain name in January, launched a website in March, and completed its first qualifying sale in June.

Each event may have evidentiary value, but they do not necessarily establish the same legal rights.

Identifying these differences early can help avoid unsupported allegations and provide a clearer picture of the company’s position.

It can also help trademark counsel determine whether additional witnesses or historical materials may be useful.

What Should Businesses Do Before a TTAB Priority Dispute Develops?

One lesson from these disputes is that trademark documentation should not begin when litigation becomes unavoidable.

Businesses benefit from maintaining dated examples of how their trademarks appear in actual commerce.

This is particularly important when a company changes its packaging, updates its website, introduces new product lines, or expands into additional services.

For established companies with incomplete archives, it may still be worthwhile to identify surviving records and preserve materials that accurately document earlier commercial activity.

The objective is not to collect documents simply because they contain the brand name.

It is to preserve evidence showing how the mark was used, what goods or services were involved, and when that activity occurred.

These details may become important long after the original transaction has been forgotten.

How Cohn Legal Approaches Trademark Priority Disputes

At Cohn Legal, PLLC, we understand that businesses do not always have perfectly organized records of their earliest years.

A founder may have spent more time developing products and serving customers than documenting every use of a brand name. That reality does not make the business’s trademark history irrelevant.

What matters is understanding which facts can be established and how those facts fit within the applicable trademark law.

In a TTAB opposition or cancellation proceeding, evaluating priority may involve examining historical business activity, reviewing available documents, considering witness testimony, and identifying potential weaknesses in the evidence.

It also means recognizing when a claimed first-use date cannot be adequately supported.

Trademark litigation requires more than confidence in a company’s history. It requires a legally sound explanation supported by the available record.

Final Thoughts: Your Trademark History Is Worth Protecting

A trademark can represent years of effort, customer relationships, and investment. Unfortunately, the evidence needed to establish those years of use is not always easy to find.

Missing invoices or incomplete business records do not automatically eliminate a company’s ability to prove trademark priority before the TTAB.

But they can make the process more demanding.

The central question is whether the available evidence, considered as a whole, establishes the trademark rights being asserted.

For business owners, the lesson is straightforward: preserve what you can, be accurate about your history, and understand that the earliest claimed date is not always the earliest legally supportable date.
