Portfolio overview

Leonhard KURZ Stiftung & Co. KG has been granted 78 US utility patents between 2015 and 2025, placing Leonhard KURZ Stiftung & Co. KG at rank #4,523 across all assignees tracked by PlainPatent. This portfolio spans 46 distinct Cooperative Patent Classification (CPC) subclasses, averaging 25.3 claims per patent with primary concentration in B42D (BOOKS; BOOK COVERS; LOOSE LEAVES; PRINTED MATTER CHARACTERISED BY IDENTIFICATION OR SECURITY FEATURES; PRINTED MATTER OF SPECIAL FORMAT OR STYLE NOT OTHERWISE PROVIDED FOR; DEVICES FOR USE THEREWITH A). As a Foreign Corporation, Leonhard KURZ Stiftung & Co. KG is one of the more focused assignees in the PatentsView dataset. By volume, Leonhard sits between Indian Institute OF Technology Bombay (78 patents, rank #4,519) and Omix-ada, Inc. (78 patents, rank #4,527) - the closest US assignees by grant volume. The composite Innovation Score of 56.9/100 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 39 grants, compared with 39 in the 2015–2019 window, a +0% 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. Leonhard KURZ Stiftung & Co. KG's 25.3 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while a multi-domain presence across 46 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Leonhard KURZ Stiftung & Co. KG against peers pursuing similar technology classes.
