USPTO Prosecution in Q3 2025: September Surge Reshapes the Quarter — and Consent Agreements Lead All Winning Strategies

---

Overview

The third quarter of 2025 delivered one of the more striking prosecution landscapes in recent memory. What appeared, through July and August, to be a relatively quiet period for USPTO trademark examination activity transformed dramatically in September, when office action volume exploded to levels more than five times the prior two months combined. At the same time, data from thousands of contested cases reveals a clear hierarchy of winning arguments — with consent agreements, disclaimer acceptances, and supplemental register filings leading the pack. For practitioners navigating an increasingly active examination environment, Q3 2025 offers a data-rich roadmap for what works, what struggles, and what to watch heading into Q4.

1. Office Action Volume: A Tale of Two Phases

The headline story of Q3 2025 is the September surge. Total office action volume across the quarter reached 28,743 actions, but that figure masks a pronounced imbalance across the three months.

Month	Total Actions	Non-Final	Final Refusals	Final Rate
July 2025	4,075	3,905	170	4.2%
August 2025	3,858	3,734	124	3.2%
September 2025	20,810	19,436	1,374	6.6%
Q3 Total	28,743	27,075	1,668	5.8%

July and August were remarkably subdued — together accounting for fewer than 8,000 total actions, or less than 28% of the quarter's output. Then September arrived with over 20,800 actions, representing a 439% month-over-month increase in total volume. Final refusals tell a particularly sharp story: August saw only 124 final actions, while September produced 1,374 — an 11x jump in a single month.

The final refusal rate itself climbed from a low of 3.2% in August to 6.6% in September, suggesting that the September wave was not simply more of the same examination work, but included a higher concentration of adversarial, later-stage actions. Whether this reflects a backlog clearing event, examiner productivity initiatives, or accelerated processing of applications filed in late 2024 and early 2025 will bear watching as Q4 data becomes available. Practitioners should brace for a continued elevated tempo if September's output reflects a new baseline rather than a one-time spike.

2. Document Activity: Applications Drive Volume, But Responses Tell the Real Story

Across all prosecution document types logged during Q3 2025, applications (APP) topped the count at 70,695 — a figure that reflects not just new filings but the administrative breadth of active prosecution dockets. Below the application tier, the document mix reveals the rhythm of active examination.

Top 10 Document Types, Q3 2025:

Rank	Document	Code	Count
1	Application	APP	70,695
2	XSearch Search Summary	XSS	29,727
3	Non-Final Action	NFIN	26,955
4	Amendment and Mail Process Complete	AMC	16,540
5	Response to Office Action	ROA	14,308
6	Notice of Design Search Code Emailed	EDS	8,512
7	Public Note	PNR	6,999
8	Specimen	SPE	4,611
9	Change Address or Representation Form	CAR	3,701
10	Filing Receipt	FRC	3,464

The XSearch Search Summary (XSS) at nearly 30,000 entries confirms the high volume of initial examination searching — a number that closely tracks and slightly exceeds the 26,955 Non-Final Actions (NFIN), as expected given that not every search produces an office action. The ratio of Responses to Office Actions (14,308 ROA) to Non-Final Actions (26,955 NFIN) at roughly 53% suggests that a significant portion of non-finals issued in prior periods are still generating responses, or that many applicants are not yet engaging — whether due to timing, abandonment, or pending deadlines carrying over from prior quarters.

Notable in the mid-tier: 2,755 Application Extensions to Response (ELR) signal a meaningful constituency of applicants buying time on office action responses, while 1,072 Notice of Revival (NREVE) entries indicate a persistent abandonment-and-revival cycle in the docket. The 970 abandonment notices (ABN) are a lagging indicator worth monitoring — if September's final refusal spike is sustained, abandonment figures are likely to rise accordingly in Q4.

3. The Refusal Landscape: Section 2(d) Dominates, but Registration Rates Tell a Nuanced Story

Across the analyzed case universe for Q3 2025, six primary refusal categories emerge, and their respective registration rates vary enormously — a finding that should directly shape practitioner strategy.

Refusal Type Profile

Refusal Type	Cases	Registered	Reg. Rate	Avg. Days to Reg.
Section 2(d) — Likelihood of Confusion	3,097	487	15.7%	128 days
Section 2(e) — Descriptiveness/Functionality	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) remains the dominant refusal by case count — more than 3,000 cases, nearly three times the next largest category. But its 15.7% registration rate is the starkest number in the dataset. For every ten applications receiving a likelihood-of-confusion refusal, fewer than two ultimately achieve registration. This is not necessarily a reflection of argument quality alone; many 2(d) situations are structurally difficult, and some applicants rationally abandon rather than escalate. Still, the contrast with other refusal categories is dramatic.

Section 2(e) refusals — covering descriptiveness and related bars — show a 92.3% registration rate on a universe of 1,136 cases, suggesting that most descriptiveness refusals are resolved successfully, often through supplemental register filings, acquired distinctiveness arguments, or successful reframing of the mark as suggestive. At 92 average days to registration, these cases also resolve relatively quickly.

Disclaimer and identification refusals are similarly high-success categories (93.9% and 93.4%, respectively), reflecting the largely procedural nature of those objections when properly addressed. Specimen refusals post the highest registration rate at 97.1% — nearly universal success when contested — and the fastest average resolution at 81 days. The takeaway: specimen issues are highly curable.

The low registration rate for 2(d) cases compared to all other refusal types underscores that likelihood-of-confusion refusals carry the highest substantive risk and deserve the most strategic front-loading at the application drafting stage.

4. Winning Strategies: What the Effectiveness Data Reveals

The argument effectiveness data from Q3 2025 covers over 3,000 individual arguments across refusal categories, scored by outcome. The results reveal a clear hierarchy — with some counterintuitive leaders at the top.

Argument Effectiveness Rankings

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

Consent Agreements: The Highest-Effectiveness Tool Few Use

With a 91.3% effectiveness rate, consent agreements top the leaderboard — but with only 67 uses during the quarter, they remain dramatically underutilized relative to their success rate. Consent agreements require cooperation from the owner of the cited mark, which is a genuine barrier, but the data suggests that when practitioners pursue them, they succeed at a very high rate. For applicants with strong commercial stakes in a mark facing a 2(d) refusal from a willing or approachable registrant, the consent agreement path deserves serious consideration before defaulting to a more adversarial response.

Disclaimer and Supplemental Register: High Volume, High Success

Disclaimer arguments (87.3% effectiveness, 609 uses) and supplemental register filings (87.0%, 563 uses) are the workhorses of Q3 prosecution — deployed frequently and successfully. These strategies align with the refusal type data: since disclaimer and 2(e) refusals both show high registration rates, the argument toolkit for resolving them is well-developed and reliably effective. The 1.145 outcome multiplier for disclaimer arguments — the highest among high-volume categories — suggests these arguments don't just succeed; they tend to accelerate or enhance the overall prosecution outcome.

Class Deletion: An Underappreciated Tactical Tool

Class deletion at 86.9% effectiveness across 184 uses is worth highlighting. Strategically narrowing the goods and services identification to eliminate the class overlap driving a 2(d) refusal is a frequently successful path that does not require overcoming the substantive confusion analysis — it sidesteps it. When applicants are attached to the mark itself more than the breadth of coverage, class deletion offers a rapid, high-probability resolution.

Cited Mark Abandoned: Monitor Registrations Before Responding

Cited mark abandoned arguments at 83.5% effectiveness remind practitioners of a simple but often overlooked step: check the status of the cited mark before drafting a response. If the blocking registration has gone abandoned or is in late-stage maintenance jeopardy, a petition to suspend or a simple status-check argument may resolve the refusal without substantive argument. With 80 uses and strong success rates, this is a quick win that should be part of every 2(d) response workflow.

The Limits of Conventional 2(d) Arguments

Arguments that get to the heart of the confusion analysis — third-party registrations (78.7%), weakness of cited mark (78.5%), and commercial impression (77.8%) — perform reasonably well but trail the top strategies. Notably, both third-party registrations and weakness arguments carry relatively low outcome multipliers (1.005 and 1.007, respectively), suggesting that while they contribute to successful outcomes, they rarely function as standalone drivers. These arguments are most effective when combined with other approaches — particularly goods amendments, class deletions, or evidence of the mark's own strength.

Goods amendment at 76.8% effectiveness across 505 uses is the highest-volume strategy of the quarter, reflecting how commonly identification narrowing factors into 2(d) responses. Its effectiveness is solid but not exceptional — and its 1.056 multiplier suggests moderate incremental benefit, pointing to cases where the goods overlap is close enough to resolve through drafting precision.

5. Refusal-Type-Specific Effectiveness Deep Dive

Matching argument effectiveness data against refusal type success rates produces an integrated picture of Q3 prosecution dynamics.

Section 2(d) cases show a 78.1% average argument effectiveness but only a 15.7% ultimate registration rate — a gap that reveals how often even good arguments fail to overcome the structural barriers of likelihood-of-confusion refusals. The 1,783 arguments tracked in this category produced only 304 successful outcomes. The implication: winning arguments in 2(d) cases are necessary but rarely sufficient. Prosecution strategy must account for the real possibility of TTAB appeal, and applicants should evaluate the strength of the underlying application before initiating a response strategy.

Section 2(e) cases, by contrast, show 84.4% average effectiveness and 1,436 successful outcomes from 1,581 arguments tracked — an outcome rate that approaches one-to-one. The tools for overcoming descriptiveness refusals are well-understood and reliably applied: suggestiveness arguments, acquired distinctiveness evidence, and supplemental register filings provide a layered toolkit that converts most 2(e) refusals into registrations.

Specimen refusals at 81.2% effectiveness and 294 successful outcomes from 296 arguments are essentially universal successes when contested — consistent with the 97.1% registration rate in the refusal type data. Specimen refusals are the most curable class in trademark prosecution.

Disclaimer refusals lead all categories in per-argument effectiveness at 89.3%, and with 47 tracked arguments producing 47 successful outcomes, the data suggests disclaimer issues are nearly always resolved when properly addressed. These refusals should rarely, if ever, result in abandonment.

6. Practical Takeaways for Q4 2025

The Q3 2025 data converges on several clear strategic imperatives for practitioners heading into the final quarter of the year:

1. Prepare for sustained high volume. September's surge to 20,810 office actions — more than five times the July-August average — likely reflects a structural shift rather than an anomaly. If USPTO examination output has reset to a higher baseline, practitioners should audit their dockets now for upcoming response deadlines and capacity constraints. The spike in final refusals (1,374 in September alone) suggests that many applications that received non-finals in prior quarters are now reaching the final action stage.

2. Front-load 2(d) strategy. With a 15.7% registration rate for likelihood-of-confusion refusals, the time to address 2(d) risk is before the application is filed — through comprehensive clearance searches, identification drafting designed to minimize overlap, and proactive assessment of whether a consent agreement path is viable. Arguments made after a 2(d) issues face long odds.

3. Elevate consent agreements. At 91.3% effectiveness, consent agreements are the highest-performing argument category in the dataset — yet they represent fewer than 2.5% of tracked arguments. For 2(d) cases where the cited mark owner is identifiable and potentially approachable, a proactive consent agreement inquiry should be a standard early step, not a last resort.

4. Use class deletion and goods amendment strategically, not reflexively. These high-volume tools (184 and 505 uses, respectively) work well when the goods/services overlap is the actual driver of the confusion analysis, but their effectiveness tapers when the marks themselves are close. Combine these approaches with weakness arguments and third-party registration evidence for stronger outcomes.

5. Don't overlook cited mark status. With an 83.5% effectiveness rate and minimal procedural burden, checking cited mark abandonment status before drafting any 2(d) response is a low-cost, high-value step. Automated docket monitoring for cited mark status changes should be standard practice.

6. Treat specimen and disclaimer refusals as administrative, not substantive. Registration rates above 93% for disclaimer and 97% for specimen refusals confirm that these issues are procedural obstacles, not material threats. Allocate prosecution resources accordingly — robust responses to these refusals can be efficient and targeted rather than exhaustive.

7. Watch abandonment rates in Q4. The 970 abandonment notices logged in Q3, combined with September's elevated final refusal volume, set up a potential Q4 abandonment spike. Practitioners representing applicants who received final refusals in September face 6-month response windows that will expire in early 2026 — proactive docket review now can prevent inadvertent abandonment.

Conclusion

Q3 2025 will be remembered primarily for September's dramatic office action surge, which transformed what was shaping up as a quiet summer quarter into one of the most active prosecution periods in recent data. Beneath that headline, the strategic picture is nuanced: likelihood-of-confusion refusals remain the hardest barrier in trademark prosecution, with registration rates well below 20%, while nearly every other refusal category resolves successfully when properly contested. The argument effectiveness data confirms that consent agreements, disclaimer-based resolutions, supplemental register elections, and strategic identification amendments are the most reliable tools in the practitioner's kit. As Q4 begins with an elevated examination tempo and a growing pool of final refusals requiring response, the data from Q3 offers a clear guide for where to focus effort — and where to cut losses.
