Portfolio overview

Sumitomo Heavy Industries, Ltd. has been granted 555 US utility patents between 2015 and 2025, placing Sumitomo Heavy Industries, Ltd. at rank #829 across all assignees tracked by PlainPatent. This portfolio spans 140 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.9 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, Sumitomo Heavy Industries, Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Sumitomo sits between Asahi Kasei Kabushiki Kaisha (557 patents, rank #825) and GREE Holdings, Inc. (549 patents, rank #833) - the closest US assignees by grant volume. The composite Innovation Score of 63.7/100 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 285 grants, compared with 270 in the 2015–2019 window, a +6% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Sumitomo Heavy Industries, Ltd.'s 9.9 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 Sumitomo Heavy Industries, Ltd. against peers pursuing similar technology classes.
