After seven steady years of upward momentum, the U.S. patent system hit an unexpected air pocket in 2025, and not a small one. Patent applications dropped a sharp 9% compared with 2024, sinking to their lowest level since 2019, a reversal that feels abrupt precisely because it follows such a long, almost complacent climb. Granted patents told a quieter version of the same story, edging down by less than one percent from 324,064 to 323,272, but even that subtle contraction matters in a system used to constant expansion. At the center of the data stands IFI CLAIMS Patent Services, a Digital Science company that compiles and interprets filings from the U.S. Patent and Trademark Office and patent offices worldwide, translating raw numbers into a lens on how companies actually think about R&D. Lily Iacurci of IFI described the sudden drop as striking, and the comment lands with extra weight because the decline raises uncomfortable questions: is this a temporary hangover from COVID-era disruptions, or the first visible sign that large corporations are quietly rethinking how much they want to reveal through patents at all?
At the top of the leaderboard, stability masks deeper shifts. Samsung held onto the number one position for the fourth year running, widening its lead with 7,054 U.S. patent grants in 2025, an 11% year-over-year increase that alone accounts for more than two percent of all patents granted in the country. TSMC remained firmly in second place with 4,194 grants, while Qualcomm stayed third, growing to 3,749 patents but still not quite reclaiming its earlier peak. Beneath that surface continuity, though, the churn is telling. IBM slipped out of the Top 10 altogether, landing at eleventh after decades of dominance, a deliberate consequence of its more selective patenting strategy. Huawei moved up into fourth place, Apple slid two spots to sixth, and several familiar names quietly lost ground. Google and Amazon dropped multiple places, Microsoft held steady, and companies often associated with innovation headlines—Tesla, Nvidia, Meta—failed to crack the Top 50 at all. One of the most dramatic moves came from LG Energy Solution, which surged 22 positions, a leap that feels less like a statistical oddity and more like a signal about where industrial research money is flowing right now.
Automotive companies added another layer to the story, hinting that the patent slowdown is not evenly distributed. Toyota jumped six places to eighth, while Honda rose seven spots, joined by upward moves from Kia, Hyundai, and GM. Ford, by contrast, fell twelve positions, an uncomfortable reminder that the transition toward electrification and advanced materials is creating clear winners and losers even among legacy manufacturers. Step back further and the geographic picture sharpens: Asia now accounts for 60% of the Top 50 patent holders, up from 48% less than a decade ago, underscoring a long-term eastward shift in industrial innovation. Although U.S.-based companies still received the largest absolute number of grants—136,131 in total—more than half of all U.S. patents were awarded to foreign companies. Japan, China, South Korea, and Germany followed, with Taiwan, China, and South Korea all posting strong year-over-year growth. The United States, notably, was the biggest decliner, down 5%, a detail that stings a bit when read alongside years of rhetoric about domestic innovation leadership.
The fastest-growing technology categories help explain why this moment feels less like a collapse and more like a reorientation. For the second year running, the leading growth area was operating or servicing of cells, closely tied to electrolysis and green hydrogen production, rising more than 23% over the past four years. Batteries and electrolytic processes dominated five of the ten fastest-growing technologies, while others focused on waste recovery, metal reclamation, hydrometallurgy, and pretreatment of scrap—unflashy work, perhaps, but essential to a circular economy and environmental mitigation. Only one category, bioinformatics, stood outside this sustainability-heavy cluster. Because IFI’s fastest-growing rankings are based on patent applications rather than grants, they act as a forward-looking signal, closer to the moment when ideas are being formed than when they are finally approved. In earlier years, those signals foreshadowed today’s AI surge; now they point toward energy diversification, material reuse, and quieter, infrastructure-level innovation. It all adds up to a year where fewer patents do not necessarily mean less ingenuity, just a shift in where companies place their bets—and how loudly they choose to announce them.
