What this shows Cal's Innovation Score is 49.5/100 (top 15% 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 Cal?

Each dot is one of Cal’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). Cal’s own 16.0 claims/patent is ABOVE the 13.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Cal's grants concentrate

Cal Poly Corporation is a focused PatentsView assignee: 45 CPC subclasses with 16.7% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2016 (5 grants) versus a trough of 1 in 2017. By volume, Cal sits between Constellium Neuf-brisach and Changzhou AAC Raytech Optronics Co., Ltd..

Cal's three-year grant acceleration

Cal Poly Corporation shows 6 grants in 2022–2024 against only 8 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.
