USPTO PatentsView assignee record - 6 granted patents across 5 technology areas, active 2016–2022. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: G06T (IMAGE DATA PROCESSING OR GENERATION, IN GENERAL).
The verdict
Keisokugiken holds 6 US patents across 5 technology areas, rank #41,163 of 50,000 tracked assignees.
Keisokugiken Co., Ltd. has been granted 6 US utility patents between 2016 and 2022, placing Keisokugiken Co., Ltd. at rank #41,163 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.0 claims per patent with primary concentration in G06T (IMAGE DATA PROCESSING OR GENERATION, IN GENERAL). As a Foreign Corporation, Keisokugiken Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Keisokugiken sits between KEDU Electric Co., Ltd. (6 patents, rank #41,159) and Keyxentic Inc. (6 patents, rank #41,167) - the closest US assignees by grant volume. The composite Innovation Score of 31.5/100 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. Between 2020 and 2025 the company received 1 grants, compared with 5 in the 2015–2019 window, a -80% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Keisokugiken Co., Ltd.'s 17.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 5 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Keisokugiken Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Keisokugiken's 6 grants land it in the top 62% 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.
