Portfolio overview

KAKE Educational Institution has been granted 9 US utility patents between 2015 and 2025, placing KAKE Educational Institution at rank #29,163 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.7 claims per patent with primary concentration in A61P (SPECIFIC THERAPEUTIC ACTIVITY OF CHEMICAL COMPOUNDS OR MEDICINAL PREPARATIONS). As a Foreign Corporation, KAKE Educational Institution is one of the more focused assignees in the PatentsView dataset. By volume, KAKE sits between K.h.s. Musical Instrument Co., Ltd. (9 patents, rank #29,159) and KCI Manufacturing Unlimited Company (9 patents, rank #29,167) - the closest US assignees by grant volume. The composite Innovation Score of 32.8/100 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 6 grants, compared with 3 in the 2015–2019 window, a +100% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. KAKE Educational Institution's 10.7 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 KAKE Educational Institution against peers pursuing similar technology classes.

Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
