Portfolio overview

Zhuhai Enpower Electric Co., Ltd. has been granted 8 US utility patents between 2019 and 2025, placing Zhuhai Enpower Electric Co., Ltd. at rank #33,970 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.1 claims per patent with primary concentration in H05K (PRINTED CIRCUITS; CASINGS OR CONSTRUCTIONAL DETAILS OF ELECTRIC APPARATUS; MANUFACTURE OF ASSEMBLAGES OF ELECTRICAL COMPONENTS). As a Foreign Corporation, Zhuhai Enpower Electric Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Zhuhai sits between Zhejiang Xunshi Technology Co. Ltd (8 patents, rank #33,966) and Zkteco USA Llc (8 patents, rank #33,974) - the closest US assignees by grant volume. The composite Innovation Score of 37.9/100 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 7 grants, compared with 1 in the 2015–2019 window, a +600% 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. Zhuhai Enpower Electric Co., Ltd.'s 18.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Zhuhai Enpower Electric Co., Ltd. against peers pursuing similar technology classes.
