California files more patents than any other state, and it is not close. In 2024, resident inventors in California received 46,454 patents, about 29.3 percent of all patents granted to U.S. residents, according to an analysis of USPTO data by Anaqua. Texas came second with 11,552 patents (7.3 percent), followed by Massachusetts at 7,976, New York at 7,605, and Washington at 6,560. The pattern is steep: one state accounts for nearly a third of the total, and the top five hold a commanding share.
The 2024 leaderboard
Drawing on the same USPTO figures, the order at the top of the table reads:
- California: 46,454 patents (29.3 percent)
- Texas: 11,552 patents (7.3 percent)
- Massachusetts: 7,976 patents (4.8 percent)
- New York: 7,605 patents (4.8 percent)
- Washington: 6,560 patents (4.1 percent)
For context, the USPTO granted 365,614 patents in fiscal year 2024, and U.S. resident inventors received 158,773 of them. The remainder went to inventors based outside the United States, a reminder that the American patent system is a global filing destination.
Why the map looks the way it does
Population explains part of it. California and Texas are the two largest states, so raw totals tilt their way. But population alone does not account for California’s share. The concentration of technology employers, research universities, and venture capital around the Bay Area and Southern California produces patents at a rate that outruns headcount.
The National Science Foundation’s science and engineering indicators make the connection explicit: the states that lead in knowledge- and technology-intensive industry output are the same states that lead in patent grants. Invention follows the industries that fund it.
Per capita tells a different story
Raw counts reward big states. Adjust for population and the ranking shifts. Smaller states with dense research clusters, including Massachusetts and Washington, punch well above their size. Massachusetts files nearly as many patents as far larger states because of the research corridor around Boston and Cambridge.
This matters for inventors outside the coastal hubs. A state can have a serious invention economy without topping the raw-count list, and the manufacturing depth that turns a patent into a product is not always located where the patents are filed.
The Midwest case
The coastal totals dominate the headline, but the upper Midwest holds a particular kind of strength. Minnesota, home to a deep bench of medical-device and industrial manufacturers, has long produced more invention per resident than its size would suggest. The legacy of large product companies in the Twin Cities seeded a regional culture of engineering and design that still feeds independent inventors.
Enhance Innovations works from that corridor. Founded in 2010 in Champlin, Minnesota, the firm combines industrial design, engineering, marketing, and licensing representation in one office, and it draws on the dense network of Midwest fabricators and manufacturers that sits within a short drive of the Twin Cities. The state ranks below California in absolute patent counts, but the supply chain that brings a product from drawing to shelf is closer at hand than the raw filing numbers imply.
Universities move the needle
State totals also reflect where research universities sit. Patents assigned to universities and their tech transfer offices concentrate in states with large public and private research systems, and those grants seed local startup activity. A region with a strong engineering school tends to show both more filings and more new companies built on licensed inventions. That feedback loop helps explain why states such as Massachusetts hold their rank year after year despite modest population, and why the Midwest’s research universities matter to the region’s inventors even when they do not top the national count.
What the state data does and does not mean
A high filing count signals where invention is concentrated, not where an idea can succeed. Patents are filed from every state, and the path from grant to market depends more on a clear plan than on a ZIP code. The USPTO’s open data on utility patents by state lets anyone trace these trends over time, and the longer view shows the same handful of states leading year after year.
For an inventor, the useful takeaway is simpler than the leaderboard. Geography shapes the odds at the margin, through access to manufacturers, design talent, and capital. It does not decide them.
