Portfolio overview

Dongguan CITY Minleon Electronics Co., Ltd. has been granted 5 US utility patents between 2018 and 2020, placing Dongguan CITY Minleon Electronics Co., Ltd. at rank #46,124 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 4.8 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, Dongguan CITY Minleon Electronics Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Dongguan sits between Dong-a Flexible Metal Tubes Co., Ltd (5 patents, rank #46,120) and Dongguan IINE Technology Co., Ltd (5 patents, rank #46,128) - the closest US assignees by grant volume. The composite Innovation Score of 20.8/100 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 2 grants, compared with 3 in the 2015–2019 window, a -33% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Dongguan CITY Minleon Electronics Co., Ltd.'s 4.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Dongguan CITY Minleon Electronics Co., Ltd. against peers pursuing similar technology classes.
