Portfolio overview

Grid4c Ltd. has been granted 6 US utility patents between 2020 and 2022, placing Grid4c Ltd. at rank #40,431 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.5 claims per patent with primary concentration in F24F (AIR-CONDITIONING; AIR-HUMIDIFICATION; VENTILATION; USE OF AIR CURRENTS FOR SCREENING). As a Foreign Corporation, Grid4c Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Grid4c sits between Great GO Cycles Inc. (6 patents, rank #40,427) and Gripwiq Holding Aps (6 patents, rank #40,435) - the closest US assignees by grant volume. The composite Innovation Score of 29.1/100 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 2020 through 2022, with 6 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. Grid4c Ltd.'s 15.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Grid4c Ltd. against peers pursuing similar technology classes.
