Across all tracked assignees
USPTO PatentsView assignee record - 9 granted patents across 6 technology areas, active 2019–2024. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: B25B (TOOLS OR BENCH DEVICES NOT OTHERWISE PROVIDED FOR, FOR FASTENING, CONNECTING, DISENGAGING OR HOLDING).
The verdict
Chien holds 9 US patents across 6 technology areas, rank #28,457 of 50,000 tracked assignees.
Chien Yu Hong Co., Ltd. has been granted 9 US utility patents between 2019 and 2024, placing Chien Yu Hong Co., Ltd. at rank #28,457 across all assignees tracked by PlainPatent. This portfolio spans 6 distinct Cooperative Patent Classification (CPC) subclasses, averaging 2.6 claims per patent with primary concentration in B25B (TOOLS OR BENCH DEVICES NOT OTHERWISE PROVIDED FOR, FOR FASTENING, CONNECTING, DISENGAGING OR HOLDING). As a Foreign Corporation, Chien Yu Hong Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Chien sits between Check Video Llc (9 patents, rank #28,453) and Chongqing Maiyi Technology Co., Ltd (9 patents, rank #28,461) - the closest US assignees by grant volume. The composite Innovation Score of 23.5/100 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 6 grants, compared with 3 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. Chien Yu Hong Co., Ltd.'s 2.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 6 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Chien Yu Hong Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Chien's 9 grants land it in the top 88% 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.
