Portfolio overview

Tunghsu Technology Group Co., Ltd. has been granted 10 US utility patents between 2022 and 2024, placing Tunghsu Technology Group Co., Ltd. at rank #27,612 across all assignees tracked by PlainPatent. This portfolio spans 17 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.1 claims per patent with primary concentration in C03B (MANUFACTURE, SHAPING, OR SUPPLEMENTARY PROCESSES). As a Foreign Corporation, Tunghsu Technology Group Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Tunghsu sits between TSO3 Inc. (10 patents, rank #27,608) and Tannas Company (10 patents, rank #27,616) - the closest US assignees by grant volume. The composite Innovation Score of 51.3/100 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 2022 through 2024, with 10 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. Tunghsu Technology Group Co., Ltd.'s 14.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 17 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Tunghsu Technology Group Co., Ltd. against peers pursuing similar technology classes.

Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
