Portfolio overview

LEEDARSON LIGHTING CO., LTD. has been granted 85 US utility patents between 2018 and 2025, placing LEEDARSON LIGHTING CO., LTD. at rank #4,204 across all assignees tracked by PlainPatent. This portfolio spans 21 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.0 claims per patent with primary concentration in F21V (FUNCTIONAL FEATURES OR DETAILS OF LIGHTING DEVICES OR SYSTEMS THEREOF; STRUCTURAL COMBINATIONS OF LIGHTING DEVICES WITH OTHER ARTICLES, NOT OTHERWISE PROVIDED FOR). As a Foreign Corporation, LEEDARSON LIGHTING CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 52.2/100 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 75 grants, compared with 10 in the 2015–2019 window — a +650% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The Foreign 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 LIGHTING CO., LTD.'s 16.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 21 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark LEEDARSON LIGHTING CO., LTD. against peers pursuing similar technology classes.
