According to the United States Patent and Trademark Office, more than 3,420,560 US patents were granted between 2015 and 2025, the window this analysis covers. Research question: How many claims does the typical US patent contain, and what does the distribution of claim depth across corporate portfolios reveal about patenting strategy?

Why claims are the real measure of a patent
According to the United States Patent and Trademark Office, the 3,420,560 US patents granted between 2015 and 2025 vary widely in how broadly they are drafted; our methodology documents the claim measurements (reviewed June 2026). A patent's value lives in its claims, not its title. Claims are the numbered legal sentences at the end of a patent that define exactly what the owner can stop others from doing. A patent might describe an elaborate invention in dozens of pages, but if its claims are narrow, competitors can design around it easily. Conversely, a small number of carefully broad claims can lock down an entire approach. Counting claims is therefore a rough but genuine proxy for how much legal ground a patent stakes out.
Across the portfolios we track, the average patent carries 14.9 claims. That figure sits in a familiar range: US practice tends to cluster around the high teens because the patent office charges fees for claims beyond twenty, which nudges applicants toward a disciplined set rather than an exhaustive one. The average masks real variation, though, and the distribution is where the strategy shows.
Three patenting postures
Among the 6,730 corporate portfolios with at least fifty granted patents, about 12% average twenty or more claims per patent — the complex, broadly scoped end of the spectrum. Roughly 62% sit in the standard 12-to-20 band, and about 26% average fewer than twelve claims, the focused end. These three postures correspond to recognizably different strategies. Complex-claim filers, common in pharmaceuticals and core electronics, draft expansive patents that are expensive to prosecute but hard to circumvent. Standard-claim filers balance cost against coverage. Focused-claim filers, often in fast-moving software, file many narrow patents quickly rather than a few broad ones slowly.
Claim depth interacts with portfolio size. A company can pursue breadth either by filing many simple patents or fewer complex ones, and the combination reveals intent. Our Innovation Score treats claim depth as one of four dimensions precisely because depth and volume tell different halves of the same story: volume measures how much a company files, while claim depth measures how much each filing tries to protect.
Reading claim depth carefully
Average claim count is a blunt instrument. It does not distinguish independent claims, which define the core invention, from dependent claims that merely add detail; a patent with three strong independent claims may be more valuable than one with thirty mostly dependent ones. It also cannot see claim quality — the precision of the language, the strength of the prior-art position, or how the claims have fared in litigation. And because the figure is averaged per company, a single outlier patent has little effect on a large portfolio but can skew a small one.
With those limits in mind, claim depth remains one of the more honest signals available from public patent data. It is harder to game than raw counts and it correlates with the seriousness of a filer's intent. When you study an individual company portfolio, the average-claims figure tells you whether the organization writes broad, defensible patents or files lean and fast — a distinction that matters as much as how many patents it holds. Compare it against the leading holders to see how the largest filers balance volume against depth.
The bottom line
The typical US patent in our dataset carries 14.9 claims, and the distribution across portfolios splits into three recognizable strategies: a small share of complex, broadly drafted portfolios, a large middle band of standard coverage, and a meaningful group of focused, lean filers. None of these is inherently better; they suit different industries and different competitive goals. What matters for analysis is that claim depth adds a dimension that raw counts cannot — it distinguishes a company that files many thin patents from one that files fewer, deeper ones, even when both hold the same total.
Use claim depth as a complement to volume, never as a replacement. A portfolio's size tells you how much a company invests in patenting; its average claim depth tells you how it invests. Read together, the two reveal whether an organization is playing a breadth game, a depth game, or a balance of both. That is a more honest picture of patent strategy than any single number, and it is available directly from public grant data without any proprietary scoring. When a figure on this site looks surprising, trace it back to these underlying signals rather than taking the headline at face value.
There is a final reason claim depth deserves attention: it is one of the few patent metrics that resists easy manipulation. A company can inflate its raw patent count by filing a flood of narrow, low-value applications, and that strategy will lift its position on a volume leaderboard without reflecting any real increase in protectable invention. Average claim depth is harder to game, because writing genuinely broad claims invites tougher examination and a higher risk of rejection, so a portfolio that sustains deep claims across thousands of patents has, in effect, passed a quality filter that a thin portfolio has not. This does not make depth a perfect proxy for value — litigation outcomes and citation patterns add information that claim counts cannot — but it does make depth a useful sanity check on volume. When a company's patent count looks impressive, the average claim depth is one of the first secondary figures worth examining to understand whether the portfolio is built for breadth of coverage or merely for the appearance of scale.
Methodology
We computed the average claims-per-patent for every assignee and analyzed the distribution across the 6,730 portfolios with at least 50 granted patents, bucketing them into focused (under 12 claims), standard (12–20), and complex (20 or more). Claim counts come from USPTO PatentsView grant records for 2015–2025. Read the full site methodology →
Data provenance and standards
Every figure above is computed deterministically from a single ingested snapshot of the public USPTO PatentsView release, never estimated, scraped from secondary summaries, or adjusted by hand. Our pipeline disambiguates assignees, normalizes corporate naming variants, aggregates grants by year and classification, and stores the reconciled results so that any number is reproducible and auditable against the original government records. Where a measurement carries unavoidable caveats — examination lag in recent grant years, the overlapping nature of classification codes, imperfect entity reconciliation across subsidiaries — we surface those limitations explicitly rather than presenting a tidier picture than the evidence supports. This commitment to transparency, verifiable provenance, and honest uncertainty is what separates rigorous analysis from decorative statistics, and it governs every study we publish.
