Quarterly USPTO Prosecution Report | Q4 2025 (October – December)

Executive Summary

The fourth quarter of 2025 produced more than 105,600 office actions across the USPTO's trademark prosecution pipeline — a volume that, on its surface, signals a busy close to the year. But beneath the raw numbers lies a more nuanced story: final refusals dropped sharply as the quarter progressed, descriptiveness refusals proved far more survivable than likelihood-of-confusion cases, and a handful of prosecution strategies — led by consent agreements and disclaimer arguments — outperformed the field by meaningful margins. For practitioners planning their 2026 prosecution calendars, the data offers clear direction on where to invest strategic effort and where to temper client expectations.

1. Office Action Volume: A Quarter That Ended Quieter Than It Started

Total office action volume for Q4 2025 reached 105,624 actions, spread across three months with notably different profiles.

Month	Total Actions	Non-Final	Final Refusals	Final Refusal Rate
October 2025	38,155	32,907	5,248	13.8%
November 2025	32,991	28,647	4,344	13.2%
December 2025	34,478	31,397	3,081	8.9%
Q4 Total	105,624	92,951	12,673	12.0%

October was the quarter's busiest month, accounting for 36% of all office actions issued. That's a familiar pattern — examiners returning from summer workflows and processing backlogged applications tend to produce an autumn surge. November pulled back to the quarter's lowest total at just under 33,000 actions, before December rebounded to roughly 34,500.

The more significant trend, however, is what happened to final refusals. The final refusal rate fell from 13.8% in October to just 8.9% in December — a 36% relative decline in a single quarter. This is not a trivial fluctuation. It may reflect a seasonal pattern in which examiners issue more non-final actions late in the year to give applicants additional response time before year-end, or it may signal that more cases are being resolved through amendment or examiner's amendment before reaching the final stage. Either way, practitioners should not interpret the December dip as a permanent shift; it warrants monitoring in Q1 2026.

Across the full quarter, non-final actions outnumbered final refusals by more than 7 to 1 (92,951 vs. 12,673), which is broadly consistent with prior quarters and reflects the USPTO's general preference for giving applicants at least one opportunity to respond before closing the record.

2. Document Activity: What the Pipeline Actually Looked Like

The document-type breakdown reveals the full scope of prosecution activity — not just what examiners sent out, but what applicants sent back and what the administrative machinery processed in response.

3. The Refusal Landscape: Section 2(d) Dominates, But Outcomes Diverge Sharply

The refusal landscape in Q4 2025 is best understood not just by which refusals are most common, but by how those refusals actually resolve — and the story there is striking.

Refusal Type Distribution and Registration Outcomes

Refusal Type	Cases	Registered	Registration Rate	Avg. Days to Registration
Section 2(d) – Likelihood of Confusion	3,097	487	15.7%	128 days
Section 2(e) – Descriptiveness	1,136	1,049	92.3%	92 days
Disclaimer	921	865	93.9%	92 days
Identification of Goods/Services	698	652	93.4%	125 days
Specimen	584	567	97.1%	81 days
Other	384	382	99.5%	98 days

Section 2(d): The High-Volume, Low-Survival Refusal

Likelihood-of-confusion refusals under Section 2(d) remain the dominant refusal type by a wide margin, accounting for 3,097 cases — more than twice the volume of the next most common refusal type. But the registration rate tells a sobering story: only 15.7% of Section 2(d) cases in this dataset resulted in registration, with an average of 128 days to get there. That is both the lowest registration rate and the longest average prosecution timeline of any refusal type tracked.

The strategic implication is clear: when an examiner cites a likelihood of confusion, the odds of overcoming it through argument alone are materially lower than for virtually any other refusal. This should calibrate both client counseling and resource allocation decisions upfront.

Section 2(e): The Overlooked High-Success Category

If Section 2(d) is the daunting refusal, Section 2(e) descriptiveness refusals are, by the numbers, the most recoverable. A 92.3% registration rate across 1,136 cases is remarkable — and faster than 2(d) cases by over a month. The explanation lies primarily in the availability of alternative pathways: applicants facing descriptiveness refusals can amend to the Supplemental Register, pursue acquired distinctiveness arguments, or restructure their goods/services descriptions to bring the mark outside the descriptive range. These are tractable options that the 2(d) framework largely does not offer.

Specimen and Disclaimer Refusals: Routine But Resolvable

Specimen refusals (97.1% registration rate, 81 days) and disclaimer requirements (93.9%, 92 days) are, functionally, administrative hurdles rather than substantive bars. Applicants who encounter these refusals and respond appropriately almost always prevail — and they do so faster than applicants in any other category. The challenge is ensuring that responses are properly substantiated, particularly for specimen refusals where a replacement specimen must meet use-in-commerce requirements.

4. Winning Strategies: What the Effectiveness Data Reveals

The argument effectiveness data is where the Q4 2025 dataset becomes most actionable. Across more than 4,000 tracked arguments spanning six refusal types, a consistent hierarchy of strategy effectiveness has emerged.

Overall Winning Argument Effectiveness by Refusal Type

Refusal Type	Arguments Tracked	Avg. Effectiveness	Successful Outcomes	Success Rate
Disclaimer	47	89.3%	47	100%
Section 2(e)	1,581	84.4%	1,436	90.8%
Specimen	296	81.2%	294	99.3%
Identification	156	78.4%	156	100%
Section 2(d)	1,783	78.1%	304	17.1%
Other	175	74.7%	174	99.4%

Note: "Successful outcomes" reflects cases reaching registration; effectiveness scores incorporate additional quality metrics beyond binary success/failure.

The dataset reveals a meaningful divergence between average effectiveness scores and raw success counts in 2(d) cases. Despite a 78.1% average effectiveness score — respectable in absolute terms — only 304 of 1,783 tracked Section 2(d) arguments resulted in registration. This gap suggests that even well-constructed 2(d) arguments frequently fail to overcome a determined examiner's position, and that the effectiveness score may partially reflect partial successes (e.g., narrowed goods, examiner's amendments) rather than full withdrawals of the refusal.

Top Argument Categories Ranked by Effectiveness

Rank	Argument Category	Avg. Effectiveness	Uses	Outcome Multiplier
1	Consent Agreement	91.3%	67	1.004
2	Disclaimer	87.3%	609	1.145
3	Supplemental Register	87.0%	563	1.125
4	Class Deletion	86.9%	184	1.060
5	Cited Mark Abandoned	83.5%	80	1.028
6	Suggestive, Not Descriptive	80.6%	156	1.088
7	Secondary Meaning	80.3%	120	1.086
8	Design Distinctiveness	79.2%	145	1.124
9	Third-Party Registrations	78.7%	120	1.005
10	Weakness of Cited Mark	78.5%	134	1.007
11	Specimen Support	78.4%	296	1.130
12	Incongruity	78.0%	50	1.058
13	Commercial Impression	77.8%	144	1.017
14	Double Entendre	76.8%	15	1.060
15	Goods Amendment	76.8%	505	1.056

Consent Agreements: Rare but Highly Effective

At 91.3% effectiveness, consent agreements are the single most effective argument category in the dataset — but with only 67 uses in the quarter, they remain a specialized tool. This makes sense: securing a consent agreement requires a cooperative relationship with the owner of the cited mark, negotiation, and often legal fees on both sides. But for applicants who can secure one, the data is unambiguous — it is the strongest available argument for overcoming a 2(d) refusal. Practitioners facing a 2(d) refusal involving a commercially accessible cited mark owner should evaluate this pathway early, not as a last resort.

Disclaimer Arguments: High Volume, High Effectiveness

With 609 uses and an 87.3% effectiveness score, disclaimer arguments are both the most frequently deployed high-performing strategy and the one with the largest outcome multiplier (1.145) among the top five. When an examiner requires a disclaimer of a descriptive or generic term, agreeing and offering the disclaimer — potentially paired with arguments about the distinctiveness of the remaining elements — resolves the case swiftly and cheaply. The 1.145 outcome multiplier suggests these cases tend to move to registration faster and with fewer complications than average.

Supplemental Register Amendments: The Underutilized Workaround

The Supplemental Register strategy (87.0% effectiveness, 563 uses, 1.125 outcome multiplier) is arguably the most underappreciated tool in the practitioner's kit for descriptiveness cases. An amendment to the Supplemental Register resolves the 2(e)(1) descriptiveness refusal entirely, preserves the application, and starts the clock on the five-year period for a potential Section 2(f) claim. For clients who need something registered — whether for enforcement purposes, licensing negotiations, or international filing bases — the Supplemental Register offers a fast, high-certainty path that pure substantive argument does not.

Cited Mark Abandoned: A Monitoring Opportunity

The cited mark abandoned argument (83.5% effectiveness, 80 uses) is worth flagging separately, not because it is frequently applicable, but because it requires proactive monitoring. If the cited mark falls into abandonment after an office action issues — either through failure to respond, failure to file a Section 8 declaration, or cancellation — the examiner's basis for the refusal evaporates. Practitioners who maintain monitoring on cited marks and move quickly when abandonment occurs are rewarded with one of the higher effectiveness rates in the dataset.

Third-Party Registrations and Weakness Arguments: Solid but Not Superior

Third-party registrations (78.7%) and weakness of the cited mark (78.5%) arguments remain standard components of a well-constructed 2(d) response — but their outcome multipliers (1.005 and 1.007, respectively) are among the lowest in the top 15. This suggests that while these arguments contribute to overall effectiveness, they rarely move the needle independently. They are best deployed as supporting arguments alongside stronger strategies rather than as standalone positions.

5. Practical Takeaways for Q1 2026

The Q4 2025 data generates several concrete implications for practitioners entering the new year.

1. Front-Load Your Section 2(d) Strategy Assessment

The data makes clear that 2(d) refusals are the hardest to overcome and the slowest to resolve when they are overcome. A 15.7% registration rate in the refusal dataset should recalibrate the internal calculus practitioners apply at the moment of filing — not just after a refusal issues. Applicants with marks that carry real 2(d) risk should receive counseling that includes the realistic odds, the likely prosecution timeline (128+ days from refusal, minimum), and the availability of design-arounds before investing in prosecution of a mark with limited survivability.

2. Evaluate Consent Agreement Viability Early

Consent agreements produce the highest effectiveness scores in the dataset (91.3%) and yet are deployed in only 67 cases per quarter. Given their efficacy, the barrier appears to be relational and logistical rather than legal. Practitioners should identify the owners of cited marks early in prosecution and assess whether outreach is feasible — before spending months on substantive arguments that are statistically less likely to succeed.

3. Don't Fight Descriptiveness If the Supplemental Register Serves the Client's Needs

Section 2(e) refusals are some of the most winnable in the dataset (84.4% effectiveness, 92.3% registration rate), and the Supplemental Register pathway (87.0% effectiveness, 1.125 outcome multiplier) deserves to be presented to clients as a genuine strategic option — not a consolation prize. For clients who need international filing bases under the Madrid Protocol, need registration for enforcement standing, or are building toward a Section 2(f) claim, the Supplemental Register is often faster, cheaper, and more certain than a prolonged distinctiveness fight.

4. Monitor Final Refusal Rates in Q1

December's 8.9% final refusal rate is a notable departure from October's 13.8%. Whether this represents a genuine examiner behavior shift, a seasonal artifact, or a pipeline anomaly will become clearer once January and February 2026 data is available. Practitioners who have pending cases approaching the final action stage should track this rate closely — if final refusals rebound in Q1, the Reconsideration Request pathway (3,863 filings in Q4 alone) will remain an important tactical option to brief clients on in advance.

5. Use Specimen Preparation as a Prevention Strategy

With a 97.1% registration rate once a specimen refusal is challenged, these refusals are essentially a process problem rather than a substantive one. The cost, however, is time and effort: an average of 81 days to registration from refusal, plus the resources of preparing a compliant response. Investing more attention in specimen preparation at the time of filing — particularly for service marks, where specimen compliance requirements are frequently misunderstood — is likely to produce a better return than responding to refusals that were preventable.

6. Consider Class Deletion as a Tactical Release Valve

Class deletion (86.9% effectiveness, 184 uses, 1.060 outcome multiplier) is a strategy that tends to get overlooked in the heat of a substantive 2(d) dispute. If a cited mark covers certain classes and the applicant's filing covers those classes plus others where there is no conflict, deleting the conflicting class — while perhaps sacrificing some protection — can unlock registration in the remaining classes quickly. Not every client will accept this trade-off, but it deserves to be on the table.

Conclusion

Q4 2025 closed with over 105,000 office actions, a notable month-over-month decline in final refusals, and a prosecution ecosystem that rewards tactical flexibility over brute-force substantive argumentation. The overarching theme is one of strategic differentiation: the gap between the best-performing argument categories (91.3% for consent agreements) and the weakest (76.8% for goods amendments and double entendre) is not trivial, and neither is the gap between a Section 2(d) case (15.7% registration rate) and a specimen case (97.1%).

Practitioners who internalize these distinctions — and counsel clients accordingly from the earliest stages of prosecution — will be better positioned to manage timelines, costs, and expectations in the quarter ahead.
