Portfolio overview

ELKAY MANUFACTURING COMPANY has been granted 55 US utility patents between 2015 and 2023, placing ELKAY MANUFACTURING COMPANY at rank #6,136 across all assignees tracked by PlainPatent. This portfolio spans 10 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.6 claims per patent with primary concentration in E03C (DOMESTIC PLUMBING INSTALLATIONS FOR FRESH WATER OR WASTE WATER ; SINKS). As a US Corporation, ELKAY MANUFACTURING COMPANY is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 33.9/100 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 30 grants, compared with 25 in the 2015–2019 window — a +20% 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. ELKAY MANUFACTURING COMPANY's 8.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 10 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark ELKAY MANUFACTURING COMPANY against peers pursuing similar technology classes.
