Portfolio overview

Xuzhou Zhirun Mining Equipment Science AND Technology Co., Ltd has been granted 6 US utility patents between 2020 and 2021, placing Xuzhou Zhirun Mining Equipment Science AND Technology Co., Ltd at rank #44,125 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.3 claims per patent with primary concentration in B66B (ELEVATORS; ESCALATORS OR MOVING WALKWAYS). As a Foreign Corporation, Xuzhou Zhirun Mining Equipment Science AND Technology Co., Ltd is one of the more focused assignees in the PatentsView dataset. By volume, Xuzhou sits between Xl-protein Gmbh (6 patents, rank #44,121) and XYZ Interactive Technologies Inc. (6 patents, rank #44,129) - the closest US assignees by grant volume. The composite Innovation Score of 24.9/100 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. Historical data spans 2020 through 2021, with 6 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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 Zhirun Mining Equipment Science AND Technology Co., Ltd's 8.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Xuzhou Zhirun Mining Equipment Science AND Technology Co., Ltd against peers pursuing similar technology classes.

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.
