USPTO PatentsView assignee record - 6 granted patents across 6 technology areas, active 2016–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: H02P (CONTROL OR REGULATION OF ELECTRIC MOTORS, ELECTRIC GENERATORS OR DYNAMO-ELECTRIC CONVERTERS; CONTROLLING TRANSFORMERS, REACTORS OR CHOKE COILS).
The verdict
Hangzhou holds 6 US patents across 6 technology areas, rank #40,597 of 50,000 tracked assignees.
Hangzhou Leaderway Electronics Co., Ltd has been granted 6 US utility patents between 2016 and 2025, placing Hangzhou Leaderway Electronics Co., Ltd at rank #40,597 across all assignees tracked by PlainPatent. This portfolio spans 6 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.3 claims per patent with primary concentration in H02P (CONTROL OR REGULATION OF ELECTRIC MOTORS, ELECTRIC GENERATORS OR DYNAMO-ELECTRIC CONVERTERS; CONTROLLING TRANSFORMERS, REACTORS OR CHOKE COILS). As a Foreign Corporation, Hangzhou Leaderway Electronics Co., Ltd is one of the more focused assignees in the PatentsView dataset. By volume, Hangzhou sits between Hancock Medical, Inc. (6 patents, rank #40,593) and Hangzhou Santan Medical Technology Co., Ltd (6 patents, rank #40,601) - the closest US assignees by grant volume. The composite Innovation Score of 45.2/100 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 4 grants, compared with 2 in the 2015–2019 window, a +100% 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. Hangzhou Leaderway Electronics Co., Ltd's 16.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 6 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hangzhou Leaderway Electronics Co., Ltd against peers pursuing similar technology classes.

How to use this portfolio
Hangzhou's 6 grants land it in the top 24% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
