Portfolio overview

Parker-hannifin Corporation has been granted 605 US utility patents between 2015 and 2025, placing Parker-hannifin Corporation at rank #758 across all assignees tracked by PlainPatent. This portfolio spans 168 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.8 claims per patent with primary concentration in F16K (VALVES; TAPS; COCKS; ACTUATING-FLOATS; DEVICES FOR VENTING OR AERATING). As a US Corporation, Parker-hannifin Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Parker-hannifin sits between GE Aviation Systems Limited (607 patents, rank #754) and Maxlinear, Inc. (602 patents, rank #762) - the closest US assignees by grant volume. The composite Innovation Score of 63.2/100 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 300 grants, compared with 305 in the 2015–2019 window, a -2% 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. Parker-hannifin Corporation's 16.8 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 Parker-hannifin Corporation against peers pursuing similar technology classes.
