A trademark application can fail without ever reaching the question of whether the mark is distinctive or likely to cause confusion. If the identification of goods is indefinite, the USPTO will refuse registration, and the applicant may not get another chance to fix it. In re Plazer IP, LLC, decided by the Trademark Trial and Appeal Board in March 2026, is a useful illustration of how that plays out.
What the Applicant Was Trying to Register
Plazer IP, LLC applied to register the mark PLAZER for goods described, at various stages of prosecution, as "sustainable plasma products produced by non-thermal plasma reaction." The application was filed under Section 1(b), meaning the applicant had not yet used the mark in commerce but had a bona fide intention to do so.
The examining attorney rejected the identification as indefinite. The applicant tried twice to amend it. The final version listed goods as "sustainable plasma products produced by non-thermal plasma reaction and having superior properties following the plasma reaction," followed by a long list of potential product attributes: improved germicidal reactivity, improved chemical reactivity, improved thermal stability, improved mechanical strength, and so on.
The TTAB affirmed the refusal.
The Legal Standard
The Trademark Act requires that an application identify, with specificity, the goods in connection with which the applicant intends to use the mark. The identification must be "specific, definite, clear, accurate, and concise." The purpose is twofold: to give the public meaningful notice of what the applicant is claiming, and to give the USPTO enough information to assess likelihood of confusion against existing registrations.
An identification can fail in two ways. It may be so vague that the nature of the goods is unclear. Or it may be so broad that it encompasses goods that fall into different international classes. Either problem will result in a refusal.
What Went Wrong
The Board's analysis focused on the phrase "sustainable plasma products." The word "products" alone is essentially useless in an identification of goods, a point the TMEP makes explicitly. Standing alone, it does not identify anything recognizable, and the USPTO will deny a filing date to any application that identifies goods only as "products."
Adding "sustainable plasma" to the front did not fix the problem. The Board found that this phrasing indicated, at most, the general field of the goods, but said nothing about what those goods actually were or what they were used for.
The applicant's various amendments approached the problem from different angles, none successfully. The first version said the goods were "in the form of gases, liquids, solids, or combinations thereof." This described physical state, not nature. The final version substituted a list of beneficial properties: improved germicidal reactivity, improved corrosion resistance, improved hardness, and the rest. This described potential benefits, not what the goods were. The Board put it plainly: the properties listing leaves one to wonder what those products are and what they are used for.
The Board also illustrated the scope problem. The identification, as written, could describe goods in multiple international classes depending on their intended use. Plasma-derived gases used as chemical catalysts would fall in Class 1. Plasma-derived products used for bone and tissue augmentation would fall in Class 5. The identification did not contain the specificity needed to resolve that ambiguity.
Arguments the Applicant Made, and Why They Did Not Work
Plazer IP made several arguments worth noting, because they come up in other identification disputes.
Common commercial name. The applicant argued that "sustainable plasma products" was the common commercial name for its goods, and that common commercial names form a sufficient basis for identification. The Board agreed with the legal principle but rejected its application here. The applicant offered no evidence that the phrase was widely understood by the general population to identify particular goods. Without that, it was not a common commercial name in any meaningful sense.
The ID Manual has no entry for these goods. The applicant pointed out that the USPTO's Acceptable Identification of Goods and Services Manual contained no entry specifically covering its products. The Board was not persuaded. The manual's purpose is to provide examples and guidance by analogy, not to enumerate every possible product. The applicant, being in the best position to know the nature of its own goods, bore the responsibility to work from that guidance and draft a specific, acceptable identification.
Deference to applicant's language. The TMEP states that deference should be given to the language set forth by the applicant in the original application. The Board clarified that this principle applies only when the applicant's language already meets the standards for a clear and specific identification. It does not require the USPTO to accept language that falls short of those standards.
The Consequence
Because the appeal had been fully briefed and decided, the applicant had no further opportunity to amend the identification. Under Trademark Rule 2.142(g), an application that has been considered and decided on appeal will not be reopened except in narrow circumstances that did not apply here. The refusal was final.
What This Means for Applicants
For applicants whose goods are technically sophisticated, novel, or difficult to categorize, the identification of goods deserves careful attention from the start. The examining attorney's office actions will include specific guidance on deficiencies, but the window to address those deficiencies is not indefinite.
The key question to answer in any identification is not how the goods are made, what physical form they take, or what benefits they provide. It is what the goods actually are and what they are used for. Those are the details the USPTO and the public need to understand the scope of the application.
If you have an application pending with an outstanding identification requirement, or you are preparing to file for goods that are difficult to describe, working with a trademark attorney before responding to the office action can help you avoid the outcome Plazer IP encountered.
