Portfolio overview

Yantai Jereh Petroleum Equipment & Technologies Co., Ltd. has been granted 161 US utility patents between 2020 and 2025, placing Yantai Jereh Petroleum Equipment & Technologies Co., Ltd. at rank #2,430 across all assignees tracked by PlainPatent. This portfolio spans 62 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.9 claims per patent with primary concentration in E21B (EARTH OR ROCK DRILLING; OBTAINING OIL, GAS, WATER, SOLUBLE OR MELTABLE MATERIALS OR A SLURRY OF MINERALS FROM WELLS). As a Foreign Corporation, Yantai Jereh Petroleum Equipment & Technologies Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Yantai sits between Positec Power Tools (suzhou) Co., Ltd. (161 patents, rank #2,426) and Feitian Technologies Co., Ltd. (160 patents, rank #2,434) - the closest US assignees by grant volume. The composite Innovation Score of 72.7/100 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 2025, with 161 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. Yantai Jereh Petroleum Equipment & Technologies Co., Ltd.'s 16.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 62 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Yantai Jereh Petroleum Equipment & Technologies Co., Ltd. against peers pursuing similar technology classes.
