Does more volume mean deeper claims for National?
Each dot is one of National’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). National’s own 10.4 claims/patent is at or below the 13.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where National's grants concentrate
National University Corporation, Iwate University is a focused PatentsView assignee: 44 CPC subclasses with 38.2% of grants classified under C08G (Macromolecular Compounds Obtained Otherwise Than BY Reactions Only Involving Unsaturated Carbon-to-carbon Bonds). Peak complete grant year is 2023 (5 grants) versus a trough of 1 in 2016. By volume, National sits between Medtronic Ventor Technologies Ltd. and Nidec Seimitsu Corporation.
National's three-year grant acceleration
National University Corporation, Iwate University shows 10 grants in 2022–2024 against only 10 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.
