The verdict
HONG holds 137 US patents across 23 technology areas, rank #2,806 of 50,000 tracked assignees.
HONG ANN TOOL Industries Co., Ltd. has been granted 137 US utility patents between 2015 and 2025, placing HONG ANN TOOL Industries Co., Ltd. at rank #2,806 across all assignees tracked by PlainPatent. This portfolio spans 23 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.7 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, HONG ANN TOOL Industries Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, HONG sits between Chervon (hk) Limited (137 patents, rank #2,802) and NEC Solution Innovators, Ltd. (137 patents, rank #2,810) - the closest US assignees by grant volume. The composite Innovation Score of 43.3/100 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 100 grants, compared with 37 in the 2015–2019 window, a +170% 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. HONG ANN TOOL Industries Co., Ltd.'s 5.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 23 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark HONG ANN TOOL Industries Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
HONG's 137 grants land it in the top 28% 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.
