When an Important TTAB Witness Is Suddenly Unavailable

Trademark Trial and Appeal Board litigation is built around evidence. A party may spend months developing its case around testimony from a founder, employee, customer, industry professional, or other individual with firsthand knowledge of important facts. But what happens when that person becomes unavailable before testimony can be completed?

A TTAB witness unavailable situation can create a serious evidentiary problem, particularly when the witness was expected to establish priority, trademark use, consumer recognition, business history, or another fact that cannot easily be proven through documents alone.

Witness availability therefore deserves attention well before the trial period begins. Unlike ordinary discovery, the testimony phase of a TTAB proceeding is designed to create evidence that the Board may consider when deciding the case. Discovery materials do not automatically become trial evidence merely because they were exchanged earlier in the proceeding.

Understanding that distinction can prevent an unexpected witness problem from turning into a much larger problem with the evidentiary record.

Discovery Testimony and Trial Testimony Are Not the Same Thing

One of the most important concepts in TTAB trial testimony is the distinction between discovering information and placing admissible evidence into the record.

During discovery, parties may take depositions, exchange documents, serve interrogatories, and request admissions. Those procedures help each side understand the opposing case and identify relevant evidence.

The existence of a discovery deposition, however, should not lead a party to assume that everything said during that deposition automatically becomes evidence at trial. TTAB practice contains specific procedures governing how testimony and other materials are made part of the record.

This becomes especially important when a witness later becomes unavailable. A party that assumed it could simply call the witness during its testimony period may discover that the opportunity is no longer available. Whether earlier testimony can be used may depend on the circumstances, the applicable evidentiary rules, and how that testimony was obtained and preserved.

The practical lesson is straightforward. Important testimony should not be treated as something that can always be recreated later.

Why Witness Unavailability Can Affect the Burden of Proof

Every TTAB claim has elements that must be established through competent evidence. Attorney argument cannot substitute for missing proof.

Consider a trademark priority dispute. A party may contend that it began using its mark years before the opposing party. If the person who personally supervised those early sales becomes unavailable, the party still needs evidence establishing the relevant dates and circumstances of use.

Invoices, advertisements, photographs, archived webpages, sales records, business correspondence, and other documents may help. Yet documents do not always explain themselves. Testimony can provide the context needed to establish what a document represents, when it was created, how it was maintained, and how it relates to actual trademark use.

The same problem can arise with claims involving abandonment, commercial strength, consumer perception, or the historical development of a brand.

If a party bears the burden of proving a fact, the unexpected loss of a witness does not ordinarily eliminate that burden. The question becomes whether the remaining record is sufficient to prove the point.

Can Prior Testimony Be Used When a TTAB Witness Becomes Unavailable?

Potentially, but the answer depends heavily on how the prior testimony was created and the procedural circumstances surrounding its proposed use.

Federal evidentiary principles recognize certain circumstances in which former testimony may be admissible when a witness is unavailable. However, unavailability is a legal concept with specific requirements. A witness is not necessarily considered unavailable simply because appearing is inconvenient or because the party would prefer to rely on an earlier statement.

There may also be questions concerning whether the opposing party previously had an adequate opportunity and similar motive to examine the witness. Those issues can become especially significant when a party seeks to rely on testimony originally taken for a different purpose.

For that reason, prior testimony should not be viewed as an automatic substitute for live or properly submitted trial testimony. Parties confronting this situation should analyze the applicable TTAB rules, TBMP guidance, Federal Rules of Evidence, and circumstances surrounding the earlier testimony.

What About a Witness Declaration?

TTAB practice permits testimony to be introduced through declarations or affidavits, subject to the opposing party’s right to cross-examine the witness.

That procedure can make TTAB testimony more efficient because a witness does not necessarily need to provide all direct testimony through a traditional oral testimony deposition. But a declaration does not make witness availability irrelevant.

Cross-examination remains an important safeguard. If a witness provides a testimony declaration but subsequently cannot participate in properly requested cross-examination, questions can arise concerning whether and to what extent that testimony may remain in the record.

This is one reason timing matters. Waiting until the end of a testimony period to secure crucial witness evidence can create unnecessary risk.

Documentary Evidence Can Become Critical

A strong TTAB record rarely depends on a single person.

Contemporaneous business records can be particularly valuable because they may corroborate testimony about historical events. An invoice dated years earlier may support a claim concerning sales. Product packaging can demonstrate how a mark appeared. Advertising records may help establish consumer exposure. Archived materials may document how a business presented its mark during a particular period.

None of this means documents automatically solve a witness problem. Evidentiary foundation, admissibility, relevance, and the proper method of introducing materials remain important.

Instead, the broader point is that corroborating evidence can make a case less dependent on one individual’s recollection. That is useful even when every expected witness remains available.

Can the TTAB Testimony Schedule Be Changed?

A witness becoming unexpectedly unavailable may also create a scheduling issue.

The TTAB operates under a scheduling order that establishes discovery, disclosure, and testimony deadlines. Parties should not assume that a deadline will automatically move because a witness cannot appear.

Depending on the circumstances and timing, a party may seek appropriate relief from the Board. The standard that applies can vary depending on what deadline has passed and what relief is requested. The reason for the witness’s unavailability, the diligence of the requesting party, potential prejudice to the opponent, and the procedural posture of the proceeding may all become relevant.

A foreseeable scheduling problem is also different from a genuine last-minute emergency. Waiting until a deadline expires can make procedural relief considerably more difficult.

Preserving Testimony Before It Becomes a Problem

The best response to witness unavailability often begins months before anyone becomes unavailable.

During discovery and pretrial preparation, counsel can identify which individuals possess knowledge that cannot readily be replaced. A company founder may be the only person capable of explaining the earliest use of a mark. A former marketing director may have unique knowledge concerning an advertising campaign. An employee preparing to leave the company may possess information that becomes much harder to obtain later.

Once those vulnerabilities are recognized, counsel can consider how the evidence should be preserved and what corroborating records exist.

This approach also improves the quality of the case generally. Even when the witness ultimately testifies without difficulty, contemporaneous documentation can make testimony more credible and provide the Board with a clearer factual record.

Former Employees Can Present Particular Challenges

Former employees deserve special consideration in TTAB proceedings because a company may lose practical control over them after employment ends.

An employee who once cooperated with counsel may later relocate, change jobs, become difficult to contact, or simply decline to participate voluntarily. The procedural tools available to obtain testimony can depend on where the witness is located and the circumstances involved.

This is particularly relevant when a departing employee has unique knowledge of early trademark use, product development, marketing, sales, or licensing practices.

Identifying those witnesses early can help counsel determine whether their knowledge is duplicated elsewhere and whether important business records should be gathered while the relevant facts remain accessible.

The Problem With Waiting Until Final Briefing

A missing witness cannot usually be repaired through persuasive writing after the record has closed.

Final briefs explain the evidence that was properly introduced. They are not an opportunity to create missing evidence. If a party reaches final briefing and realizes that a critical factual proposition depends on testimony that never entered the record, simply stating the fact in the brief does not make it evidence.

This is why TTAB evidence strategy should begin long before the testimony periods.

A useful trial record is deliberately built. Each important factual proposition should be connected to evidence capable of establishing it, rather than relying on the assumption that a particular witness will eventually fill every gap.

Building a TTAB Case That Does Not Depend on One Witness

Witness unavailability illustrates a broader truth about trademark litigation before the Board. A compelling factual story is not enough. The facts supporting that story must actually become part of the evidentiary record through appropriate procedures.

Businesses involved in a trademark opposition or trademark cancellation should therefore think carefully about who holds important institutional knowledge and how that knowledge can be corroborated. The earlier those issues are identified, the more options counsel generally has for developing the record.

When an essential witness unexpectedly becomes unavailable, the consequences will depend on the specific facts, the testimony already preserved, the reason for the unavailability, the remaining evidence, and the procedural stage of the case. Experienced TTAB counsel can evaluate those circumstances and determine what procedural or evidentiary options may remain.

At Cohn Legal, we understand that protecting a trademark sometimes means protecting the evidence behind it. Careful preparation can help ensure that a TTAB case does not rise or fall because one important witness is no longer available when trial arrives.
