Portfolio overview

ACO Sevrin Ahlmann Gmbh & Co KG has been granted 16 US utility patents between 2015 and 2019, placing ACO Sevrin Ahlmann Gmbh & Co KG at rank #17,400 across all assignees tracked by PlainPatent. This portfolio spans 15 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.1 claims per patent with primary concentration in E03F (SEWERS; CESSPOOLS). As a Foreign Corporation, ACO Sevrin Ahlmann Gmbh & Co KG is one of the more focused assignees in the PatentsView dataset. By volume, ACO sits between AADG, Inc. (16 patents, rank #17,396) and ADCO Proucts, Llc (16 patents, rank #17,404) - the closest US assignees by grant volume. The composite Innovation Score of 30.2/100 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 0 grants, compared with 16 in the 2015–2019 window, a -100% 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. ACO Sevrin Ahlmann Gmbh & Co KG's 11.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 15 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark ACO Sevrin Ahlmann Gmbh & Co KG 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.
