Portfolio overview

Hydac Technology Gmbh has been granted 65 US utility patents between 2015 and 2025, placing Hydac Technology Gmbh at rank #5,287 across all assignees tracked by PlainPatent. This portfolio spans 43 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.8 claims per patent with primary concentration in F15B (SYSTEMS ACTING BY MEANS OF FLUIDS IN GENERAL; FLUID-PRESSURE ACTUATORS, e.g. SERVOMOTORS; DETAILS OF FLUID-PRESSURE SYSTEMS, NOT OTHERWISE PROVIDED FOR). As a Foreign Corporation, Hydac Technology Gmbh is one of the more focused assignees in the PatentsView dataset. By volume, Hydac sits between Graco Children's Products, Inc. (65 patents, rank #5,283) and Inari Medical, Inc. (65 patents, rank #5,291) - the closest US assignees by grant volume. The composite Innovation Score of 49.8/100 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 30 grants, compared with 35 in the 2015–2019 window, a -14% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The Foreign 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. Hydac Technology Gmbh's 15.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 43 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hydac Technology Gmbh 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.
