Portfolio overview

TANG CHOU INDUSTRIAL CO., LTD. has been granted 8 US utility patents between 2020 and 2024, placing TANG CHOU INDUSTRIAL CO., LTD. at rank #33,509 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.3 claims per patent with primary concentration in B25G (HANDLES FOR HAND IMPLEMENTS). As a Foreign Corporation, TANG CHOU INDUSTRIAL CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 42.3/100 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 2024, with 8 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. TANG CHOU INDUSTRIAL CO., LTD.'s 11.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 5 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark TANG CHOU INDUSTRIAL CO., LTD. against peers pursuing similar technology classes.
