How many US patents are there?

Figuring out precisely how many U.S. patents exist is less like checking a single ledger and more like tracking a massive, ever-changing river of intellectual property. While the U.S. Patent and Trademark Office (USPTO) has been granting rights since the country’s earliest days, providing a single cumulative total that encompasses every patent ever issued—including those that have long since expired or lapsed—is surprisingly difficult to pin down in one simple figure. ^[4] What is clearer, however, is the sheer volume of innovation currently protected and the furious pace at which new protections are being added each year.

# Total Issued

The most relevant measure for understanding the current state of protection is the number of patents granted annually, and perhaps more importantly, the number of patents in force. Looking at recent yearly activity, the flow of new rights through the system is substantial. For example, in 2023, the USPTO granted approximately 315,245 patents. ^[6] This contrasts with the prior year (2022, based on WIPO data context) or an earlier estimate where the US granted 388,900 total patents in 2020. ^[2] This variation highlights that patent grant numbers can fluctuate based on office efficiency and the backlog clearance cycle. ^[6]

Furthermore, the volume of applications attempting to enter the system demonstrates ongoing commitment to domestic innovation. In fiscal year 2023, the USPTO received about 594,143 new utility applications alone. While Source 4 provides a detailed breakdown going back to 1790, the most recent yearly statistics available show that applications have remained high, with one estimate suggesting the USPTO received over 700,000 applications in 2024. For context on the examination load, one source suggests that patent examiners at the USPTO review an average of 22 applications per month.

# Patents In Force

If we focus only on rights actively maintained through payment of renewal fees, the number becomes a powerful indicator of current economic IP assets. As of 2023, the United States had an estimated 3.5 million patents in force. ^[6] This figure is second globally only to China, which recorded 5 million patents in force that same year. ^[6] This difference between annual grants and patents in force speaks volumes about the lifespan of intellectual property. A patent is granted for up to 20 years, but a significant portion of granted rights do not last that long, either because they are intentionally abandoned or the required maintenance fees are not paid. ^[6] The fact that the US added 112,000 patents in force in 2023 alone shows that while old patents lapse, the rate of new, maintained protection is keeping the total figure climbing steadily. ^[6]

# Global Standing

The U.S. patent system remains a critical target for inventors worldwide, cementing its authority in the global innovation landscape. When comparing the sheer volume of grants issued by national offices in 2024 data, China led with over 1 million grants, but the United States followed closely, registering 603,194 total patent grants (though another source indicates 315,245 grants in 2023). ^[3][6][7] This difference in annual grant reporting—whether it's based on the filing office's own tally or WIPO's compiled data—shows how different methodologies can change the headline number, but the US remains firmly in the top tier. ^[3][6]

Crucially, the US remains highly attractive to international entities. Around 45% of all patent applications submitted to the USPTO come from foreign applicants, underscoring the market's importance to global players. In fact, the IP office of the US attracted the most non-resident applications in 2023, receiving more than twice as many as its closest competitor. ^[6]

# Process Strain

The question of how many patents exist is inherently tied to the question of how fast the system can process them. The USPTO deals with an immense volume, which inevitably leads to backlogs. At the close of Fiscal Year 2023, the total inventory of patent applications pending—those waiting for any final decision—was reported at 1,148,601. This inventory level has remained high, crossing the one million mark around 2006.

This large pending queue directly influences the timeline for inventors. The average time for a patent application to reach a final decision sits around 24 months, with the first official feedback (the first office action) arriving in about 16.5 months. While the allowance rate—the percentage of applications that ultimately succeed—is about 54%, the journey to that decision is lengthy.

Thinking about this administrative load offers an important perspective: if an organization secures 1,000 utility patents but its competitor secures only 100, the immediate advantage is clear, but the competitor might have received their 100 patents three years sooner because they chose a different filing strategy or a less crowded technology class. The 24-month pendency means that time-to-market for IP protection is a strategic asset in itself, often more valuable than sheer volume. For entities counting on rapid protection, the large, consistent backlog acts as a natural barrier to entry, slowing down everyone.

# Ownership Concentration

The total number of patents is not distributed evenly across millions of inventors; rather, it is heavily concentrated among a relatively small number of major organizations. Examining the Top 300 Organizations Granted U.S. Patents in 2024 reveals this intense focus. ^[7]

The top holders command portfolios vastly larger than the next tier. For instance, the top two organizations listed in the 2024 data—Samsung Electronics Co., Ltd. and LG Corporation—received 9,304 and 5,156 utility patents in 2024, respectively. ^[7] To put the US federal contribution in context, the US Federal Government ranked 45th, receiving 919 patents in 2024. ^[7] For any small or medium-sized business, the competitive reality is that the vast majority of the active patent landscape is controlled by these entrenched players. ^[7]

This concentration suggests that while the USPTO grants hundreds of thousands of patents yearly, the most valuable and enforceable rights—those the owners are willing to pay maintenance fees for—cluster around entities with the deepest pockets and the broadest technological interests. ^[6][7] This structure means that a single new patent from a large holder can appear deceptively small against their massive portfolio, even as it blocks smaller market entrants from pursuing related improvements.

# Interpreting the Numbers

When assessing the total patent count, it’s useful to consider the ratio of granted patents to the population. While the exact cumulative total is elusive, using the 3.5 million patents in force in 2023 ^[6] against the US population of roughly 330 million gives an estimated figure of over 10,600 active patents per million residents. This provides a tangible benchmark for national innovation intensity.

Another key interpretation lies in the difference between office data (where a patent is filed) and origin data (where the inventor resides). The USPTO is an office that attracts massive foreign filings, yet the origin data for US applicants shows they filed over 242,000 applications abroad in 2023. ^[6] This demonstrates a dual strategic reality: innovators want US protection, but US entities must seek international protection to secure true global rights, acknowledging that US patent rights are territorial. ^[6] The pursuit of foreign-oriented patent families is often seen as a proxy for higher-value inventions because of the associated cost and commitment required to file across multiple jurisdictions. ^[6]
