Portfolio overview

Carrier Corporation has been granted 1,756 US utility patents between 2015 and 2025, placing Carrier Corporation at rank #234 across all assignees tracked by PlainPatent. This portfolio spans 232 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.3 claims per patent with primary concentration in F25B (REFRIGERATION MACHINES, PLANTS OR SYSTEMS; COMBINED HEATING AND REFRIGERATION SYSTEMS; HEAT PUMP SYSTEMS). As a US Corporation, Carrier Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Carrier sits between Novartis Ag (1,768 patents, rank #230) and Baker Hughes Holdings Llc (1,746 patents, rank #238) - the closest US assignees by grant volume. The composite Innovation Score of 69.0/100 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 1,339 grants, compared with 417 in the 2015–2019 window, a +221% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The US 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. Carrier Corporation's 14.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, 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 Carrier Corporation 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.
