Technology Class Leaders
Top patent holder in each of the 100 largest CPC technology subclasses, drawn from US patents granted 2015–2025 (USPTO via PatentsView). See our methodology.
The Cooperative Patent Classification (CPC) system, jointly maintained by the USPTO and European Patent Office, organizes US patents into 670 technology subclasses tracked by PlainPatent. Each subclass represents a coherent technology domain — semiconductor lithography, antibody therapeutics, internal-combustion engine valves, and so on — and the company that holds the most grants in a given subclass is, by volume, the dominant patent producer in that domain. The 100 subclasses ranked below are the 100 most active by overall grant count between 2015 and 2025.
Volume leadership does not always equal market leadership. A company can dominate a CPC subclass without leading the corresponding product category — for example, a defense contractor may hold many patents in a software subclass without selling commercial software. Treat this leaderboard as a structural map of who is filing where, then use the per-technology pages to read the rest of the field and the per-company pages to see whether a leader's patents reflect a product strategy or a defensive moat.
