The verdict
Cerego holds 9 US patents across 4 technology areas, rank #28,346 of 50,000 tracked assignees.
Cerego Japan Kabushiki Kaisha has been granted 9 US utility patents between 2021 and 2023, placing Cerego Japan Kabushiki Kaisha at rank #28,346 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 24.3 claims per patent with primary concentration in G09B (EDUCATIONAL OR DEMONSTRATION APPLIANCES; APPLIANCES FOR TEACHING, OR COMMUNICATING WITH, THE BLIND, DEAF OR MUTE; MODELS; PLANETARIA; GLOBES; MAPS; DIAGRAMS). As a Foreign Corporation, Cerego Japan Kabushiki Kaisha is one of the more focused assignees in the PatentsView dataset. By volume, Cerego sits between Center FOR Abrasives AND Refractories Research & Development C.a.r.r.d. Gmbh (9 patents, rank #28,342) and Changzhou Canbo Travel Products Co., Ltd. (9 patents, rank #28,350) - the closest US assignees by grant volume. The composite Innovation Score of 49.6/100 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 2021 through 2023, with 9 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. Cerego Japan Kabushiki Kaisha's 24.3 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Cerego Japan Kabushiki Kaisha against peers pursuing similar technology classes.

How to use this portfolio
Cerego's 9 grants land it in the top 14% 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.
