Bad faith trademark filings are applications submitted without a genuine plan to use the mark in commerce — usually to block a competitor, extract a payout from the rightful brand owner, or trade on a famous name. Federal law requires every applicant to declare a bona fide intent to use the mark, and filings that lack that intent can be opposed before they register or canceled after. The tools sit with the Trademark Trial and Appeal Board, and the earlier you act, the cheaper the fight.
What Makes a Filing “Bad Faith”
The Lanham Act, at 15 U.S.C. § 1051(b), requires anyone filing an intent-to-use application to submit a verified statement of “bona fide intention, under circumstances showing the good faith of such person, to use a trademark in commerce.”1Office of the Law Revision Counsel. 15 USC 1051 – Application for Registration; Verification Bad faith exists when the applicant makes that sworn statement despite having no real plan to sell goods or services under the mark.
Sloppy paperwork or an overly optimistic business plan is not the same thing. The line gets crossed when the filer knows another company has superior rights to the name, or when the application is designed to warehouse a mark for leverage rather than for any commercial purpose. The TTAB looks at objective evidence of what the applicant actually did — or didn’t do — after filing to judge whether the stated intent was real.
During examination, the USPTO generally accepts the applicant’s sworn intent at face value. An examiner won’t investigate whether a business plan exists unless the record obviously suggests otherwise. That means most bad faith challenges come from third parties with something at stake, after the application publishes.
The Patterns to Recognize
Trademark Squatting
Squatting is the most familiar version. Someone registers marks they have no intention of using, then contacts the business that actually needs the name and demands payment. The usual targets are emerging brands, foreign companies that haven’t yet filed in the United States, and businesses expanding into new product categories. TTAB decisions treat a pattern of registering marks tied to other people’s businesses as strong evidence of improper intent.
Ghost Applications
Ghost applications list goods or services the applicant has no capacity to provide. A single filing might claim rights across clothing, electronics, industrial machinery, and restaurant services with no prototype, supplier, or marketing plan for any of them. Legitimate businesses do sometimes file in multiple classes, but they can point to concrete steps toward using the mark in each one. A filing that reads like a wish list signals an attempt to block competitors rather than to compete.
Free-Riding on Famous Marks
Free-riding targets well-known brands. The filer picks a name confusingly similar to a famous mark and registers it in a different product category, hoping consumers will assume a connection. The Lanham Act bars registration of a mark that “so resembles a mark registered in the Patent and Trademark Office” or previously used in the United States “as to be likely, when used on or in connection with the goods of the applicant, to cause confusion, or to cause mistake, or to deceive.”2Office of the Law Revision Counsel. 15 USC 1052 – Trademarks Registrable on Principal Register The similarity to a famous mark tends to make the bad intent hard to explain away.
Stopping a Filing Before It Registers
Every application that clears examination is published in the weekly Trademark Official Gazette, which opens a 30-day window for anyone who would be harmed by the registration to object.3United States Patent and Trademark Office. Approval for Publication This is the cheapest and simplest moment to act. Blocking a mark here avoids the longer, costlier fight of cancellation later.
If you need more time, you can request an extension of time to oppose at no cost. The first extension is either 30 additional days (granted automatically) or 90 days (with a showing of good cause). A further 60 days is available for good cause after that. A final 60-day extension requires either the applicant’s written consent or extraordinary circumstances. The total cannot exceed 180 days from publication.4United States Patent and Trademark Office. TBMP Chapter 0200 – Extensions of Time to Oppose
Letters of Protest as a Lighter Alternative
A letter of protest lets you submit evidence directly to the examining attorney handling a pending application. You can flag grounds for refusal such as likelihood of confusion with your existing mark and attach supporting documents. The examining attorney reviews the evidence independently; your legal arguments are not forwarded, only the evidence itself.5United States Patent and Trademark Office. Letter of Protest Practice Tip The filing fee is modest, and this route is worth considering when your evidence is strong but you want to avoid a full TTAB proceeding.
One caveat matters: filing a letter of protest does not extend your time to oppose. If the mark publishes while your protest is pending, you still need to file a notice of opposition or request an extension to preserve your rights.
Canceling a Registration After the Fact
If a bad faith mark has already registered, your remedy shifts from opposition to cancellation, and the available grounds depend on how old the registration is. Within the first five years, you can petition on any ground that would have prevented registration in the first place, including likelihood of confusion with your existing mark. After the five-year mark, the grounds narrow considerably.6Office of the Law Revision Counsel. 15 USC 1064 – Cancellation of Registration
Some grounds have no time limit at all. You can petition at any time based on:
- Fraud on the USPTO in obtaining the registration.
- Abandonment, meaning the registrant stopped using the mark and doesn’t intend to resume.
- Genericness, where the mark has become a common name for the product rather than a brand identifier.
- Functionality, where the mark is a functional feature rather than a source identifier.
- Misrepresentation of source, where use of the mark misleads consumers about who makes the product.
A separate ground opens three years after registration: if the registrant has never used the mark in commerce on some or all of the listed goods, cancellation is available on that basis alone.6Office of the Law Revision Counsel. 15 USC 1064 – Cancellation of Registration Ghost applications are especially vulnerable here.
A note on fraud specifically: it overlaps with bad faith but is not the same thing. Fraud requires proof that the applicant knowingly made a false, material statement with intent to deceive the USPTO, and the challenger must show this by clear and convincing evidence — a higher bar than the ordinary civil standard.7United States Patent and Trademark Office. Table of Fraud Cases Bad faith conduct that falls short of an outright lie can still support cancellation on other grounds, such as abandonment, lack of bona fide intent, or non-use.
Building the Evidence
The strength of your evidence drives the outcome of any opposition or cancellation. Start by pulling the application’s serial number or the registration number from the USPTO’s Trademark Status and Document Retrieval system.8United States Patent and Trademark Office. Checking the Status of a Trademark Application or Registration You’ll need it for every filing.
Evidence of your own prior use establishes standing. Dated invoices, marketing materials, website archives, and social media posts predating the challenged filing all help prove you were using the mark first. Time-stamped records are harder to dispute.
On the other side, you need to show what the applicant was — or wasn’t — doing with the mark. Public records showing dozens of registrations without a single product ever sold under any of them are powerful. Correspondence matters too. If the applicant contacted you offering to sell the registration for an inflated price shortly after filing, save every email and letter. That kind of demand is close to a confession of improper intent.
Filing at the TTAB
The USPTO modernized its filing system in 2025. Notices of opposition and petitions for cancellation are now filed through TTAB Center, the board’s updated electronic platform, rather than the older ESTTA system.9United States Patent and Trademark Office. USPTO Announces New Filing Option Available Online for Trademark Trial and Appeal Board Proceedings The filing fee is $600 per class of goods or services when submitted electronically, or $700 per class on paper.10United States Patent and Trademark Office. USPTO Fee Schedule A challenge to a three-class registration runs $1,800 in filing fees alone.
Once you file and pay, the system opens a proceeding and notifies the other side. For proceedings instituted on or after September 4, 2025, the respondent has 60 days from the institution order to answer, up from the previous 40 days.11Federal Register. Change in Time Initially Set to File an Answer in a Trial Proceeding Before the Trademark Trial and Appeal Board If the respondent fails to answer, you can seek a default judgment, which typically leads to the mark being abandoned or canceled. After the answer, the board issues a schedule for discovery, testimony, and briefing. Contested cases generally run 12 to 18 months, longer with extensive discovery.
Sanctions and Attorney Fees
Losing the registration is not the only consequence a bad faith filer faces. The USPTO’s administrative sanctions process lets the Commissioner for Trademarks refuse to consider a filing, terminate an application, or bar a person from submitting documents in trademark matters before the office.12United States Patent and Trademark Office. Administrative Sanctions Process
The Lanham Act also lets courts award reasonable attorney fees to the prevailing party in “exceptional cases.”13Office of the Law Revision Counsel. 15 USC 1117 – Recovery for Violation of Rights; Profits, Damages and Costs A registration obtained through deliberate bad faith is the kind of conduct that can qualify. Fee awards in trademark litigation can reach six figures. One catch: the fee-shifting provision applies in federal court, not in TTAB proceedings. Recovering attorney fees usually means filing a separate lawsuit, which is worth weighing when you decide where to bring your challenge.
