Portfolio overview

Xiamen ECO Lighting Co. Ltd. has been granted 284 US utility patents between 2017 and 2025, placing Xiamen ECO Lighting Co. Ltd. at rank #1,466 across all assignees tracked by PlainPatent. This portfolio spans 45 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.6 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, Xiamen ECO Lighting Co. Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Xiamen sits between L&P Property Management Company (284 patents, rank #1,462) and Nanjing Chervon Industry Co., Ltd. (283 patents, rank #1,470) - the closest US assignees by grant volume. The composite Innovation Score of 55.0/100 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 217 grants, compared with 67 in the 2015–2019 window, a +224% 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. Xiamen ECO Lighting Co. Ltd.'s 14.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 45 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Xiamen ECO Lighting Co. Ltd. against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
