Portfolio overview

Hydro-gear Limited Partnership has been granted 232 US utility patents between 2015 and 2025, placing Hydro-gear Limited Partnership at rank #1,751 across all assignees tracked by PlainPatent. This portfolio spans 49 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.4 claims per patent with primary concentration in B60K (ARRANGEMENT OR MOUNTING OF PROPULSION UNITS OR OF TRANSMISSIONS IN VEHICLES; ARRANGEMENT OR MOUNTING OF PLURAL DIVERSE PRIME-MOVERS IN VEHICLES; AUXILIARY DRIVES FOR VEHICLES; INSTRUMENTATION OR DASHB). As a US Corporation, Hydro-gear Limited Partnership is one of the more focused assignees in the PatentsView dataset. By volume, Hydro-gear sits between Sidel Participations S.a.s (233 patents, rank #1,747) and Trustees Of Tufts College (232 patents, rank #1,755) - the closest US assignees by grant volume. The composite Innovation Score of 59.1/100 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 106 grants, compared with 126 in the 2015–2019 window, a -16% 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. Hydro-gear Limited Partnership's 19.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 49 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hydro-gear Limited Partnership against peers pursuing similar technology classes.
