The verdict
ZENG holds 12 US patents across 11 technology areas, rank #23,703 of 50,000 tracked assignees.
ZENG Hsing Industrial Co., Ltd. has been granted 12 US utility patents between 2017 and 2024, placing ZENG Hsing Industrial Co., Ltd. at rank #23,703 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.2 claims per patent with primary concentration in D05B (SEWING). As a Foreign Corporation, ZENG Hsing Industrial Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, ZENG sits between You Map Inc. (12 patents, rank #23,699) and Zhejiang Ausun Pharmaceutical Co., Ltd. (12 patents, rank #23,707) - the closest US assignees by grant volume. The composite Innovation Score of 28.3/100 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 5 grants, compared with 7 in the 2015–2019 window, a -29% 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. ZENG Hsing Industrial Co., Ltd.'s 9.2 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 ZENG Hsing Industrial Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
ZENG's 12 grants land it in the top 73% 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.
