USPTO PatentsView assignee record - 101 granted patents across 39 technology areas, active 2015–2025. 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
Zhongshan holds 101 US patents across 39 technology areas, rank #3,644 of 50,000 tracked assignees.
Zhongshan Broad-ocean Motor Co., Ltd. has been granted 101 US utility patents between 2015 and 2025, placing Zhongshan Broad-ocean Motor Co., Ltd. at rank #3,644 across all assignees tracked by PlainPatent. This portfolio spans 39 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.5 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, Zhongshan Broad-ocean Motor Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Zhongshan sits between Thermo Fisher Scientific Inc. (101 patents, rank #3,640) and Arnold & Richter CINE Technik Gmbh & Co. Betriebs KG (100 patents, rank #3,648) - the closest US assignees by grant volume. The composite Innovation Score of 50.4/100 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 39 grants, compared with 62 in the 2015–2019 window, a -37% 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. Zhongshan Broad-ocean Motor Co., Ltd.'s 13.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 39 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Zhongshan Broad-ocean Motor Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Zhongshan's 101 grants land it in the top 13% 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.
