Portfolio overview

Chan Li Machinery Co., Ltd. has been granted 26 US utility patents between 2015 and 2025, placing Chan Li Machinery Co., Ltd. at rank #11,601 across all assignees tracked by PlainPatent. This portfolio spans 25 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.9 claims per patent with primary concentration in B65H (HANDLING THIN OR FILAMENTARY MATERIAL, e.g. SHEETS, WEBS, CABLES). As a Foreign Corporation, Chan Li Machinery Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Chan sits between Caterpillar Underground Mining Pty Ltd. (26 patents, rank #11,597) and Chiral Photonics, Inc. (26 patents, rank #11,605) - the closest US assignees by grant volume. The composite Innovation Score of 42.2/100 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 13 grants, compared with 13 in the 2015–2019 window, a +0% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Chan Li Machinery Co., Ltd.'s 8.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 25 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Chan Li Machinery Co., Ltd. against peers pursuing similar technology classes.
