Portfolio overview

Diehl Metall Stiftung & Co. KG has been granted 7 US utility patents between 2016 and 2025, placing Diehl Metall Stiftung & Co. KG at rank #35,051 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.7 claims per patent with primary concentration in F16D (COUPLINGS FOR TRANSMITTING ROTATION; CLUTCHES; BRAKES). As a Foreign Corporation, Diehl Metall Stiftung & Co. KG is one of the more focused assignees in the PatentsView dataset. By volume, Diehl sits between Diakopto, Inc. (7 patents, rank #35,047) and Digital Voice Systems, Inc. (7 patents, rank #35,055) - the closest US assignees by grant volume. The composite Innovation Score of 26.6/100 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 4 grants, compared with 3 in the 2015–2019 window, a +33% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Diehl Metall Stiftung & Co. KG's 15.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 8 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Diehl Metall Stiftung & Co. KG against peers pursuing similar technology classes.
