Portfolio overview

Xuzhou COAL MINE Safety Equipment Manufacture Co., Ltd. has been granted 10 US utility patents between 2017 and 2024, placing Xuzhou COAL MINE Safety Equipment Manufacture Co., Ltd. at rank #27,843 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.1 claims per patent with primary concentration in B66B (ELEVATORS; ESCALATORS OR MOVING WALKWAYS). As a Foreign Corporation, Xuzhou COAL MINE Safety Equipment Manufacture Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Xuzhou sits between Xiwing E-commerce(zhuhai) Co., Ltd (10 patents, rank #27,839) and Xenco Medical, Llc (10 patents, rank #27,847) - the closest US assignees by grant volume. The composite Innovation Score of 25.4/100 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 7 grants, compared with 3 in the 2015–2019 window, a +133% 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. Xuzhou COAL MINE Safety Equipment Manufacture Co., Ltd.'s 7.1 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 Xuzhou COAL MINE Safety Equipment Manufacture Co., Ltd. against peers pursuing similar technology classes.
