Portfolio overview

SIGMASTAR TECHNOLOGY LTD. has been granted 55 US utility patents between 2021 and 2025, placing SIGMASTAR TECHNOLOGY LTD. at rank #6,187 across all assignees tracked by PlainPatent. This portfolio spans 22 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.7 claims per patent with primary concentration in G06F (ELECTRIC DIGITAL DATA PROCESSING). As a Foreign Corporation, SIGMASTAR TECHNOLOGY LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 58.1/100 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 2021 through 2025, with 55 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. SIGMASTAR TECHNOLOGY LTD.'s 12.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 22 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark SIGMASTAR TECHNOLOGY LTD. against peers pursuing similar technology classes.
