What this shows Iowa's Innovation Score is 34.4/100 (47th percentile 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 Iowa?

Each dot is one of Iowa’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). Iowa’s own 17.4 claims/patent is ABOVE the 14.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Iowa's grants concentrate

Iowa Corn Promotion Board is a focused PatentsView assignee: 9 CPC subclasses with 58.3% of grants classified under B01J (Chemical OR Physical Processes, e.g. Catalysis OR Colloid CHEMISTRY; Their Relevant Apparatus). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2015. By volume, Iowa sits between International Plant Propagation Technology, Ltd and Istituto Superiore di Sanità.

Iowa's three-year grant acceleration

Iowa Corn Promotion Board shows 2 grants in 2022–2024 against only 3 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.
