How many patents does Kyushu University hold?

Kyushu University holds 52 US utility patents granted between 2015 and 2023, spanning 57 technology areas.

What is Kyushu University's Innovation Score?

Kyushu University has an Innovation Score of 46.8 out of 100 (top 20% of the corpus). This composite metric weighs portfolio volume (40%), grant velocity (20%), technology breadth (25%), and claim depth (15%).

What technology areas does Kyushu University focus on?

Kyushu University's top technology area is C08F (Macromolecular Compounds Obtained BY Reactions Only Involving Carbon-to-carbon Unsaturated Bonds) with 14 patents, ranking #198 of 1,231 assignees active in that subclass. Grants appear in 57 CPC subclasses total.

Is Kyushu University's patent grant rate increasing or decreasing?

Kyushu University's recent grant velocity is -73% compared to the prior five-year period (grant years, not application filing dates). Grant activity has slowed relative to earlier years.

What does claim depth mean for Kyushu University's patents?

Kyushu University's patents average 12.1 claims each. This is an aggregate descriptive count from the grant record; it does not establish claim scope, legal strength, enforceability, or design-around risk.

How is the Kyushu University patent data sourced?

All patent data comes from USPTO PatentsView, a public research dataset maintained by the United States Patent and Trademark Office covering US granted utility patents from 2015 to 2025.

What this shows Kyushu's Innovation Score is 46.8/100 (top 20% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Kyushu?

Each dot is one of Kyushu’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Kyushu’s own 12.1 claims/patent is at or below the 15.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How Kyushu's grant cadence moved

Between 2020–2024, Kyushu University received 11 grants versus 41 in 2015–2019 (-73% equal-window velocity, below median growth). Across complete PatentsView years, output peaked in 2017 at 11 grants and bottomed in 2021 at 1. Lead class C08F accounts for 26.9% of the portfolio across 57 subclasses. Volume neighbours: Isis Pharmaceuticals, Inc. (#6,448) and Limagrain Europe S.A. (#6,456).

Kyushu's three-year grant acceleration

Kyushu University shows 2 grants in 2022–2024 against only 16 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
