Portfolio overview
Hamilton Sundstrand Corporation (HSC) has been granted 3,501 US utility patents between 2015 and 2025, placing Hamilton Sundstrand Corporation (HSC) at rank #103 across all assignees tracked by PlainPatent. This portfolio spans 264 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.3 claims per patent with primary concentration in B64D (EQUIPMENT FOR FITTING IN OR TO AIRCRAFT; FLIGHT SUITS; PARACHUTES; ARRANGEMENT OR MOUNTING OF POWER PLANTS OR PROPULSION TRANSMISSIONS IN AIRCRAFT). As a US Corporation, Hamilton Sundstrand Corporation (HSC) is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 67.5/100 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 2,087 grants, compared with 1,414 in the 2015–2019 window — a +48% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Hamilton Sundstrand Corporation (HSC)'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 Hamilton Sundstrand Corporation (HSC) against peers pursuing similar technology classes.
