What this shows Public's Innovation Score is 47.2/100 (top 19% 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 Public?

Each dot is one of Public’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). Public’s own 10.9 claims/patent is ABOVE the 9.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Public's grants concentrate

Public University Corporation Nagoya City University is a focused PatentsView assignee: 25 CPC subclasses with 52.2% of grants classified under C12N (Microorganisms OR ENZYMES; Compositions THEREOF; Propagating, Preserving, OR Maintaining MICROORGANISMS; Mutation OR Genetic ENGINEERING; Culture Media). Peak complete grant year is 2017 (4 grants) versus a trough of 1 in 2015. By volume, Public sits between POMA and Pigeon Corporation.

Public's three-year grant acceleration

Public University Corporation Nagoya City University shows 9 grants in 2022–2024 against only 5 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.
