Across all tracked assignees
USPTO PatentsView assignee record - 21 granted patents across 9 technology areas, active 2017–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: B25C (HAND-HELD NAILING OR STAPLING TOOLS; MANUALLY OPERATED PORTABLE STAPLING TOOLS).
The verdict
Zhejiang holds 21 US patents across 9 technology areas, rank #14,410 of 50,000 tracked assignees.
Zhejiang Rongpeng Air Tools Co., Ltd. has been granted 21 US utility patents between 2017 and 2025, placing Zhejiang Rongpeng Air Tools Co., Ltd. at rank #14,410 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 4.7 claims per patent with primary concentration in B25C (HAND-HELD NAILING OR STAPLING TOOLS; MANUALLY OPERATED PORTABLE STAPLING TOOLS). As a Foreign Corporation, Zhejiang Rongpeng Air Tools Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Zhejiang sits between Zobele España, S.a. (21 patents, rank #14,406) and 1372934 B.c. Ltd. (20 patents, rank #14,414) - the closest US assignees by grant volume. The composite Innovation Score of 37.5/100 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 19 grants, compared with 2 in the 2015–2019 window, a +850% 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. Zhejiang Rongpeng Air Tools Co., Ltd.'s 4.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Zhejiang Rongpeng Air Tools Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Zhejiang's 21 grants land it in the top 44% 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.
