Portfolio overview

Ludwig Hettich Holding Gmbh & Co. KG has been granted 9 US utility patents between 2018 and 2025, placing Ludwig Hettich Holding Gmbh & Co. KG at rank #29,319 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 22.6 claims per patent with primary concentration in F16B (DEVICES FOR FASTENING OR SECURING CONSTRUCTIONAL ELEMENTS OR MACHINE PARTS TOGETHER, e.g. NAILS, BOLTS, CIRCLIPS, CLAMPS, CLIPS OR WEDGES; JOINTS OR JOINTING). As a Foreign Corporation, Ludwig Hettich Holding Gmbh & Co. KG is one of the more focused assignees in the PatentsView dataset. By volume, Ludwig sits between Loop Energy Inc. (9 patents, rank #29,315) and Lumitec, Llc (9 patents, rank #29,323) - the closest US assignees by grant volume. The composite Innovation Score of 46.5/100 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 5 grants, compared with 4 in the 2015–2019 window, a +25% 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. Ludwig Hettich Holding Gmbh & Co. KG's 22.6 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Ludwig Hettich Holding Gmbh & Co. KG against peers pursuing similar technology classes.
