Portfolio overview

Sargent Manufacturing Company has been granted 75 US utility patents between 2015 and 2025, placing Sargent Manufacturing Company at rank #4,686 across all assignees tracked by PlainPatent. This portfolio spans 26 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.6 claims per patent with primary concentration in E05B (LOCKS; ACCESSORIES THEREFOR; HANDCUFFS). As a US Corporation, Sargent Manufacturing Company is one of the more focused assignees in the PatentsView dataset. By volume, Sargent sits between Progress Rail Locomotive Inc. (75 patents, rank #4,682) and Southwest Jiaotong University (75 patents, rank #4,690) - 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 43 grants, compared with 32 in the 2015–2019 window, a +34% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Sargent Manufacturing Company's 14.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 26 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Sargent Manufacturing Company 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.
