Portfolio overview

HUNAN BRUNP EV RECYCLING CO., LTD. has been granted 44 US utility patents between 2023 and 2025, placing HUNAN BRUNP EV RECYCLING CO., LTD. at rank #7,420 across all assignees tracked by PlainPatent. This portfolio spans 30 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.8 claims per patent with primary concentration in H01M (PROCESSES OR MEANS, e.g. BATTERIES, FOR THE DIRECT CONVERSION OF CHEMICAL ENERGY INTO ELECTRICAL ENERGY). As a Foreign Corporation, HUNAN BRUNP EV RECYCLING CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 57.8/100 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 2023 through 2025, with 44 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. HUNAN BRUNP EV RECYCLING CO., LTD.'s 8.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 30 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark HUNAN BRUNP EV RECYCLING CO., LTD. against peers pursuing similar technology classes.
