Why a Pending Intent-to-Use Application Can Beat Your Client's Earlier Actual Use
Constructive use under Section 7(c) of the Lanham Act relates an intent-to-use applicant's priority back to its filing date once the mark registers, defeating anyone who began using the mark after that date. A clearance search that dismisses a pending ITU application because no one is using the mark misjudges the risk: the filing date, not use in commerce, sets priority.
A clearance search turns up a pending intent-to-use application for a mark close to the one your client wants to adopt. There is no registration, no specimen, no sign anyone is selling anything under it. The easy read is that the applicant has no rights yet, so your client can adopt and start using now and build priority through first use in commerce. That read is wrong, and it is one of the most expensive mistakes in trademark clearance. Under Section 7(c) of the Lanham Act, if that application matures into a registration, the applicant's priority relates back to the filing date, nationwide. Your client's intervening use, however genuine and however first-in-the-market, loses to a filing date that predates it. The pending application you dismissed was holding priority the entire time.
What constructive use under Section 7(c) actually does
Section 7(c), 15 U.S.C. § 1057(c), was added by the Trademark Law Revision Act of 1988 and took effect in November 1989, when intent-to-use applications first became available. It solved a problem the intent-to-use system created. An applicant who files based on a bona fide intent to use has, by definition, not used the mark yet. Without some priority mechanism, that applicant could be beaten to the market by anyone who started using the same mark the day after the application filed. Section 7(c) supplies the mechanism.
The statute provides that, contingent on registration on the Principal Register, the filing of the application constitutes constructive use of the mark, conferring a right of priority nationwide in effect as of the filing date. The two operative pieces:
- Contingent on registration. Constructive use is not a right the applicant holds outright while the application sits pending. It vests when and if the mark registers. But once it vests, it dates back to the filing date, not the registration date. That relation-back is the whole point.
- Nationwide in effect. Ordinary common-law priority is territorial and grows with actual use. Constructive use is national from the filing date, before a single sale. It puts the applicant in a position no common-law user reaches without a registration.
The result is a priority date that can sit years ahead of any use, invisible to anyone who measures rights by what is happening in the market.
The exceptions that survive: who is not cut off
Section 7(c) is not absolute. The nationwide priority runs against everyone except a person whose mark has not been abandoned and who, before the applicant's filing date, falls into one of three categories under § 1057(c):
- Prior use. A person who used the mark in commerce before the applicant's filing date. That earlier user keeps priority, though generally confined to the territory of its actual use.
- Prior application. A person who filed an application to register the mark that is pending or has resulted in registration, with an earlier filing date.
- Prior foreign priority. A person entitled to an earlier priority filing date under § 1126(d) or § 1141g, the Paris Convention and Madrid Protocol priority provisions.
Read the first exception carefully, because it is the one clearance most often misapplies. It protects the party who used the mark before the application was filed. It does nothing for the party who used the mark after the filing date. A junior user who starts using the day after an intent-to-use application filed is not a prior user. That user is precisely who Section 7(c) was written to subordinate.
The scenario clearance gets wrong
Put dates on it, because the mistake lives in the sequence.
- March 1: A competitor files an intent-to-use application for a mark. No use, no products, nothing public beyond the application itself.
- June 1: Your client, having cleared the mark against registrations and active use and seen nothing selling, adopts the same or a confusingly similar mark and begins using it in commerce.
- The following year: The competitor's application matures to registration.
Your client used first in the real world. It does not matter. The competitor's constructive use dates to March 1, three months before your client's first use, and it is nationwide. Your client is a junior user everywhere, with no prior-use territory to fall back on, because it did not use before March 1. The investment in the mark from June forward was built on top of someone else's priority.
The Trademark Trial and Appeal Board confirmed that an intent-to-use applicant can rely on the constructive use filing date as its priority date, and can do so defensively even before the registration issues. In Zirco Corp. v. American Telephone and Telegraph Co., 21 USPQ2d 1542 (TTAB 1991), the Board held that the right to rely on the constructive use date comes into existence when the intent-to-use application is filed, so an applicant can assert that date against a third party claiming common-law rights. The Second Circuit carried the same logic into the injunction context in WarnerVision Entertainment Inc. v. Empire of Carolina, Inc., 101 F.3d 259 (2d Cir. 1996), reversing a preliminary injunction that would have stopped an intent-to-use applicant from making the very use it needed to complete registration and perfect its filing-date priority. The pending application is not dormant. It is a priority claim waiting to vest.
Why "they aren't using it" is the wrong question
The instinct in clearance is to weight a conflict by activity in the market: is the mark in use, on what goods, in what territory, how strong is the presence. For registered marks and common-law users, that instinct is correct. For a pending intent-to-use application, it inverts the analysis. The question is not whether the applicant is using the mark. The question is the filing date and whether the application is on a path to registration.
| Registered or common-law conflict | Pending intent-to-use application | |
|---|---|---|
| Source of priority | Use in commerce, or registration | Filing date, once the mark registers |
| What to measure | Extent and territory of actual use | Filing date, and whether the application will register |
| Effect of client's later use | May coexist or carve out territory | Junior nationwide if the application registers |
| Visible in the market | Usually yes | Often not at all |
Because the applicant may have no market footprint, an intent-to-use conflict is the one most likely to be underweighted or waved through, and it is the one that can most cleanly defeat a client who adopts in reliance on an empty market. The correct move on finding a live intent-to-use application with an earlier filing date is to treat the filing date as the priority date it will become, and to track the application forward: does it publish, does a statement of use get filed, does it register, or does it abandon. An application that dies never vests constructive use. An application that registers relates its priority back to a date that may already be behind your client's adoption.
Timing matters here too, because an intent-to-use applicant does not have to move fast. After a notice of allowance, the applicant has an initial six months to file a statement of use and can request extensions in six-month increments up to a total of 36 months under 15 U.S.C. § 1051(d). A conflicting application can therefore sit unresolved for up to three years after allowance, holding its filing-date priority in reserve while your client builds a brand on top of it. Clearing the mark once and closing the file leaves that period unwatched.
This is the gap that a register-deep clearance is built to close. Redrift's Clearance and Watch surface pending applications with their filing dates and status, including intent-to-use filings that carry no market presence, and keep them in view as they move toward registration or abandonment, so counsel weighs latent constructive-use priority rather than only what is visibly in use. The fabric surfaces the filing and its posture. Whether it is a real conflict, and whether the constructive-use date defeats your client, stays with the lawyer.
The discipline is a single reordering. When a pending intent-to-use application surfaces near a mark your client wants, do not ask whether anyone is using it. Ask when it was filed, and assume that date becomes the priority date the day it registers. If the filing predates your client's intended adoption, first use in commerce will not save the position, and the cheapest response is to know that before the client spends anything on the mark.
