Portfolio overview
KENALL MANUFACTURING COMPANY has been granted 88 US utility patents between 2015 and 2024, placing KENALL MANUFACTURING COMPANY at rank #4,089 across all assignees tracked by PlainPatent. This portfolio spans 18 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.3 claims per patent with primary concentration in F21Y (INDEXING SCHEME ASSOCIATED WITH SUBCLASSES F21K, F21L, F21S and F21V, RELATING TO THE FORM OR THE KIND OF THE LIGHT SOURCES OR OF THE COLOUR OF THE LIGHT EMITTED). As a US Corporation, KENALL MANUFACTURING COMPANY is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 39.2/100 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 26 grants, compared with 62 in the 2015–2019 window — a -58% 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. KENALL MANUFACTURING COMPANY's 11.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 18 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark KENALL MANUFACTURING COMPANY against peers pursuing similar technology classes.
