Portfolio overview

Sikorsky Aircraft Corporation has been granted 631 US utility patents between 2015 and 2024, placing Sikorsky Aircraft Corporation at rank #723 across all assignees tracked by PlainPatent. This portfolio spans 147 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.5 claims per patent with primary concentration in B64C (AEROPLANES; HELICOPTERS). As a US Corporation, Sikorsky Aircraft Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Sikorsky sits between The Regents Of The University Of Colorado, A Body Corporate (634 patents, rank #719) and Lennox Industries Inc. (629 patents, rank #727) - the closest US assignees by grant volume. The composite Innovation Score of 56.7/100 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 233 grants, compared with 398 in the 2015–2019 window, a -41% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Sikorsky Aircraft Corporation's 14.5 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 Sikorsky Aircraft 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.
