Portfolio overview

Daikin Industries, Ltd. has been granted 2,229 US utility patents between 2015 and 2025, placing Daikin Industries, Ltd. at rank #177 across all assignees tracked by PlainPatent. This portfolio spans 232 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.4 claims per patent with primary concentration in F25B (REFRIGERATION MACHINES, PLANTS OR SYSTEMS; COMBINED HEATING AND REFRIGERATION SYSTEMS; HEAT PUMP SYSTEMS). As a Foreign Corporation, Daikin Industries, Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Daikin sits between LG Energy Solution, Ltd. (2,270 patents, rank #173) and Jaguar LAND Rover Limited (2,182 patents, rank #181) - the closest US assignees by grant volume. The composite Innovation Score of 68.0/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Between 2020 and 2025 the company received 1,366 grants, compared with 863 in the 2015–2019 window, a +58% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. Daikin Industries, Ltd.'s 10.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Daikin Industries, Ltd. against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
