Across all tracked assignees
USPTO PatentsView assignee record - 5 granted patents across 3 technology areas, active 2023–2024. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: G09F (DISPLAYING; ADVERTISING; SIGNS; LABELS OR NAME-PLATES; SEALS).
The verdict
JAST holds 5 US patents across 3 technology areas, rank #47,911 of 50,000 tracked assignees.
JAST Company Limited has been granted 5 US utility patents between 2023 and 2024, placing JAST Company Limited at rank #47,911 across all assignees tracked by PlainPatent. This portfolio spans 3 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.4 claims per patent with primary concentration in G09F (DISPLAYING; ADVERTISING; SIGNS; LABELS OR NAME-PLATES; SEALS). As a Foreign Corporation, JAST Company Limited is one of the more focused assignees in the PatentsView dataset. By volume, JAST sits between Japan Marine United Corporation (5 patents, rank #47,907) and JCT Solutions Pty Ltd. (5 patents, rank #47,915) - the closest US assignees by grant volume. The composite Innovation Score of 39.1/100 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 2023 through 2024, with 5 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. JAST Company Limited's 11.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 3 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark JAST Company Limited against peers pursuing similar technology classes.

How to use this portfolio
JAST's 5 grants land it in the top 39% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
