Portfolio overview

Leggett & Platt Canada Co. has been granted 36 US utility patents between 2015 and 2025, placing Leggett & Platt Canada Co. at rank #8,852 across all assignees tracked by PlainPatent. This portfolio spans 17 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.4 claims per patent with primary concentration in B60N (SEATS SPECIALLY ADAPTED FOR VEHICLES; VEHICLE PASSENGER ACCOMMODATION NOT OTHERWISE PROVIDED FOR). As a Foreign Corporation, Leggett & Platt Canada Co. is one of the more focused assignees in the PatentsView dataset. By volume, Leggett sits between Kodiak Networks Inc (36 patents, rank #8,848) and Life Technologies Holdings PTE Ltd (36 patents, rank #8,856) - the closest US assignees by grant volume. The composite Innovation Score of 46.1/100 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 19 grants, compared with 17 in the 2015–2019 window, a +12% 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. Leggett & Platt Canada Co.'s 19.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 17 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Leggett & Platt Canada Co. 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.
