Portfolio overview
LEEDARSON AMERICA INC. has been granted 20 US utility patents between 2019 and 2022, placing LEEDARSON AMERICA INC. at rank #14,741 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.9 claims per patent with primary concentration in H05B (ELECTRIC HEATING; ELECTRIC LIGHT SOURCES NOT OTHERWISE PROVIDED FOR; CIRCUIT ARRANGEMENTS FOR ELECTRIC LIGHT SOURCES, IN GENERAL). As a US Corporation, LEEDARSON AMERICA INC. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 34.6/100 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 14 grants, compared with 6 in the 2015–2019 window, a +133% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. LEEDARSON AMERICA INC.'s 16.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark LEEDARSON AMERICA INC. against peers pursuing similar technology classes.
