Portfolio overview
ACSL Ltd. has been granted 7 US utility patents between 2022 and 2025, placing ACSL Ltd. at rank #34,058 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.7 claims per patent with primary concentration in B64U (UNMANNED AERIAL VEHICLES [UAV]; EQUIPMENT THEREFOR). As a Foreign Corporation, ACSL Ltd. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 45.9/100 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 2025, with 7 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. ACSL Ltd.'s 11.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark ACSL Ltd. against peers pursuing similar technology classes.
