Portfolio overview

4DS Memory, Limited has been granted 10 US utility patents between 2020 and 2023, placing 4DS Memory, Limited at rank #25,619 across all assignees tracked by PlainPatent. This portfolio spans 3 distinct Cooperative Patent Classification (CPC) subclasses, averaging 23.2 claims per patent with primary concentration in H10N (ELECTRIC SOLID-STATE DEVICES NOT OTHERWISE PROVIDED FOR). As a Foreign Corporation, 4DS Memory, Limited is one of the more focused assignees in the PatentsView dataset. By volume, 4DS sits between 1st Defence Industries Ltd. (10 patents, rank #25,615) and A LA Carte Media, Inc. (10 patents, rank #25,623) - the closest US assignees by grant volume. The composite Innovation Score of 30.0/100 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 2023, 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. 4DS Memory, Limited's 23.2 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while specialization in 3 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark 4DS Memory, Limited against peers pursuing similar technology classes.
