TTAB Precedent: Likelihood of Confusion (2024–2025) Key Takeaways
Eight precedential decisions from 2024 clarify when marks are "confusingly similar"—and when they're not. Here's what brand owners need to know.
This is Part 1 of our 6-part series on the TTAB's 30 precedential decisions from 2024. These rulings are being incorporated into the November 2025 TMEP and will shape trademark examination for years to come.
Likelihood of confusion is the heart of trademark law. It's why we have trademarks at all—to prevent consumers from being confused about the source of goods and services. In 2024, the TTAB issued eight precedential decisions refining how this critical test is applied.
Let's break down what these decisions mean for brand owners and practitioners.
The Framework: DuPont Factors Refresher
Before diving into the cases, a quick reminder: likelihood of confusion is evaluated using the 13 DuPont factors, with the most important typically being:
- Similarity of the marks (appearance, sound, meaning, commercial impression)
- Similarity of the goods/services
- Similarity of trade channels
- Conditions of purchase (sophistication of buyers)
- Fame of the prior mark
- Actual confusion evidence
Not every factor applies in every case, and no single factor is determinative. With that context, here are the 2024 decisions.
Decision 1: TRIPLEYE vs. 3RD EYE - When Conceptual Similarity Isn't Enough
Case: Precedential No. 28 Outcome: TRIPLEYE found NOT confusingly similar to 3RD EYE for software
What Happened
An applicant sought to register TRIPLEYE for software products. The examining attorney refused registration based on a prior registration for 3RD EYE covering similar software goods.
The TTAB's Analysis
Despite both marks evoking the concept of a "third eye," the Board found insufficient similarity:
- Visual appearance: TRIPLEYE (one word) vs. 3RD EYE (two words with numeral)
- Sound: Different pronunciation patterns
- Commercial impression: While conceptually similar, the overall impression differed enough
Why It Matters
This decision is a win for applicants. It confirms that conceptual similarity alone doesn't doom an application. If your mark evokes a similar concept but differs in appearance, sound, and overall impression, you may have room to coexist.
Practical tip: When conducting clearance searches, don't automatically reject marks that share a concept with existing registrations. Analyze the full commercial impression.
Decision 2: CAPTAIN CANNABIS - Priority Through Analogous Use
Case: Precedential No. 1 Outcome: Registration cancelled; opposer established priority through analogous use
What Happened
This case involved competing claims to CAPTAIN CANNABIS for comic books and related goods. The key question: who had priority?
The TTAB's Analysis
The Board found that the opposer established priority through analogous use—promotional activities that created public awareness of the mark before formal trademark use began.
Analogous use can include:
- Publicity and advertising
- Trade show appearances
- Pre-launch marketing
- Media coverage
Why It Matters
You don't need actual sales to establish priority. If you're building a brand and generating public awareness, document everything:
- Press releases and media coverage
- Social media engagement
- Trade show materials
- Pre-order announcements
- Any dated evidence of public association
Practical tip: If you're launching a new brand, start building your paper trail of public awareness from day one. Screenshots, press clips, and dated materials could be crucial in a future dispute.
Decision 3: UPC - Rejecting the "Something More" Requirement
Case: Precedential No. 15 Outcome: Section 2(d) refusal affirmed; "something more" requirement rejected
What Happened
An applicant argued that even if the standard likelihood of confusion factors were met, the USPTO should require "something more" before refusing registration.
The TTAB's Analysis
The Board firmly rejected this argument. The standard DuPont factor analysis is sufficient. There's no additional burden on the USPTO to show "something more" beyond the established framework.
Why It Matters
This decision closes a potential loophole. Applicants cannot argue that meeting the DuPont factors is somehow insufficient to establish likelihood of confusion.
Practical tip: Don't count on creative legal arguments to overcome a straightforward likelihood of confusion analysis. If the factors weigh against you, focus on distinguishing your mark or goods.
Decision 4: SAGEFORTH vs. SAGE CENTRAL - The Weight of Shared Elements
Case: Precedential No. 5 Outcome: SAGEFORTH found confusingly similar to SAGE CENTRAL
What Happened
The applicant sought to register SAGEFORTH for services that overlapped with those covered by the prior registration for SAGE CENTRAL.
The TTAB's Analysis
The Board found the shared element "SAGE" created sufficient similarity, particularly given:
- Similar services
- Overlapping trade channels
- The dominant nature of the shared element
Why It Matters
When your mark shares a dominant element with a prior registration, the remaining differences may not save you—especially if the goods/services are related.
Practical tip: If your proposed mark shares a key term with existing registrations in your space, consider whether the additional elements create sufficient distinction. "SAGE + [something]" may face challenges in any category where SAGE-formative marks exist.
Decision 5: DISTRICT OF FASHION - Priority Goes to the Opposer
Case: Precedential No. 25 Outcome: Priority awarded to opposer over employee
What Happened
This case involved a priority dispute where an employee claimed rights to a mark. The opposer (presumably the employer or a related party) contested the application.
The TTAB's Analysis
The Board found that the opposer had superior rights, reinforcing that employment relationships and the circumstances of a mark's creation matter to priority analysis.
Why It Matters
If you're building a brand in an employment or contractor context, clarity about trademark ownership is essential from the start.
Practical tip: Employment agreements and contractor agreements should clearly address trademark ownership. Don't assume—document it.
Decision 6: PERMITS.COM vs. PERMIT.COM - Supplemental Registration Doesn't Protect
Case: Precedential No. 20 Outcome: PERMITS.COM supplemental registration cancelled despite prior user of PERMIT.COM
What Happened
This case involved competing claims to domain-name-style marks (PERMITS.COM vs. PERMIT.COM). One party had a supplemental registration.
The TTAB's Analysis
The Board cancelled the supplemental registration, reinforcing that supplemental registrations provide limited protection. They don't establish the same presumptions as principal registrations.
Why It Matters
Supplemental registration is better than nothing, but it's not a shield. A prior user with stronger rights can still seek cancellation.
Practical tip: If your mark is on the Supplemental Register, work toward acquiring distinctiveness so you can move to the Principal Register. Supplemental registration is a placeholder, not a fortress.
Decision 7: Red-White-Blue vs. Red-Top Fence Posts
Case: Precedential No. 19 Outcome: Marks found NOT confusingly similar for fence posts
What Happened
This case involved color marks for fence posts—a red-white-blue pattern versus a red-top pattern.
The TTAB's Analysis
Despite both marks using red and being applied to fence posts, the Board found insufficient similarity. The overall commercial impression of a tricolor pattern differs from a single-color top.
Why It Matters
Color marks are highly specific. The exact configuration matters more than shared colors.
Practical tip: If you're considering a color trademark, document the specific configuration precisely. And know that even in the same product category, differently configured color marks may coexist.
Decision 8: BLOOKE - Cancelled for Bicycles (Part II)
Case: Precedential No. 18 (Part II) Outcome: BLOOKE registration cancelled on likelihood of confusion grounds
What Happened
The BLOOKE case has two parts (we'll cover the fraud aspect in Part 2 of this series). On likelihood of confusion, the Board found BLOOKE confusingly similar to the prior mark for bicycles.
The TTAB's Analysis
The Board applied standard DuPont analysis, finding the marks sufficiently similar for overlapping goods.
Why It Matters
This case shows that even where fraud is alleged, the Board will still analyze likelihood of confusion as an independent ground. A registration can be cancelled on multiple bases.
Key Takeaways for Brand Owners
Do Your Clearance Research
These eight decisions reinforce that likelihood of confusion analysis is fact-specific and nuanced. A proper clearance search should:
- Identify marks with shared elements (not just identical marks)
- Analyze goods/services overlap broadly
- Consider conceptual similarity AND overall commercial impression
- Document the analysis for future reference
Protect Your Priority
Priority matters. Whether through actual use, analogous use, or clear documentation:
- Keep dated records of all brand-building activities
- Document the first use in commerce precisely
- Preserve evidence of pre-launch publicity
- Maintain clear ownership records
Don't Rely on Technicalities
The Board won't require "something more" beyond the DuPont factors. If your mark fails the standard analysis, creative legal arguments probably won't save you.
Monitor the Register
Even after registration, your mark can be challenged. Use monitoring tools to track potentially conflicting applications and address threats early.
