What this shows Chulalongkorn's Innovation Score is 43.9/100 (top 27% 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 Chulalongkorn?

Each dot is one of Chulalongkorn’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). Chulalongkorn’s own 11.9 claims/patent is at or below the 13.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Chulalongkorn's grants concentrate

Chulalongkorn University is a focused PatentsView assignee: 20 CPC subclasses with 25% of grants classified under Y02P (Climate Change Mitigation Technologies IN THE Production OR Processing OF Goods). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2022. By volume, Chulalongkorn sits between Chiome Bioscience Inc. and Cimc Containers Holding Company Ltd..

Chulalongkorn's three-year grant acceleration

Chulalongkorn University shows 2 grants in 2022–2024 against only 0 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.
