Portfolio overview

C. & E. FEIN Gmbh has been granted 73 US utility patents between 2015 and 2025, placing C. & E. FEIN Gmbh at rank #4,754 across all assignees tracked by PlainPatent. This portfolio spans 33 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.5 claims per patent with primary concentration in B24B (MACHINES, DEVICES, OR PROCESSES FOR GRINDING OR POLISHING ; DRESSING OR CONDITIONING OF ABRADING SURFACES; FEEDING OF GRINDING, POLISHING, OR LAPPING AGENTS). As a Foreign Corporation, C. & E. FEIN Gmbh is one of the more focused assignees in the PatentsView dataset. By volume, C. sits between Actelion Pharmaceuticals Ltd. (73 patents, rank #4,750) and Clearmotion, Inc. (73 patents, rank #4,758) - the closest US assignees by grant volume. The composite Innovation Score of 50.4/100 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 34 grants, compared with 39 in the 2015–2019 window, a -13% 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. C. & E. FEIN Gmbh's 16.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 33 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark C. & E. FEIN 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.
