Portfolio overview

Willo Products Company, Inc. has been granted 7 US utility patents between 2016 and 2025, placing Willo Products Company, Inc. at rank #38,268 across all assignees tracked by PlainPatent. This portfolio spans 1 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.3 claims per patent with primary concentration in E05B (LOCKS; ACCESSORIES THEREFOR; HANDCUFFS). As a US Corporation, Willo Products Company, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Willo sits between WILA B.v. (7 patents, rank #38,264) and WISE S.r.l. (7 patents, rank #38,272) - the closest US assignees by grant volume. The composite Innovation Score of 21.5/100 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 3 grants, compared with 4 in the 2015–2019 window, a -25% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US 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. Willo Products Company, Inc.'s 14.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 1 subclass reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Willo Products Company, Inc. against peers pursuing similar technology classes.
