Portfolio overview

Dresser-rand Company has been granted 141 US utility patents between 2015 and 2022, placing Dresser-rand Company at rank #2,739 across all assignees tracked by PlainPatent. This portfolio spans 69 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.9 claims per patent with primary concentration in F04D (NON-POSITIVE-DISPLACEMENT PUMPS). As a US Corporation, Dresser-rand Company is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Dresser-rand sits between The George Washington University (142 patents, rank #2,735) and KOWA Company, Ltd. (141 patents, rank #2,743) - the closest US assignees by grant volume. The composite Innovation Score of 53.1/100 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 32 grants, compared with 109 in the 2015–2019 window, a -71% 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. Dresser-rand Company's 15.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 69 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Dresser-rand Company against peers pursuing similar technology classes.
