Portfolio overview

BRASSCRAFT MANUFACTURING COMPANY has been granted 36 US utility patents between 2015 and 2023, placing BRASSCRAFT MANUFACTURING COMPANY at rank #8,750 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.4 claims per patent with primary concentration in E03C (DOMESTIC PLUMBING INSTALLATIONS FOR FRESH WATER OR WASTE WATER ; SINKS). As a US Corporation, BRASSCRAFT MANUFACTURING COMPANY is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 35.5/100 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 7 grants, compared with 29 in the 2015–2019 window — a -76% 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. BRASSCRAFT MANUFACTURING COMPANY's 12.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark BRASSCRAFT MANUFACTURING COMPANY against peers pursuing similar technology classes.
