What this shows California's Innovation Score is 32.8/100 (42nd 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 California?

Each dot is one of California’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). California’s own 15.5 claims/patent is at or below the 16.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where California's grants concentrate

California Expanded Metal Products Company is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under E04B (General Building CONSTRUCTIONS; Walls, e.g. PARTITIONS; ROOFS; FLOORS; CEILINGS; Insulation OR Other Protection OF Buildings). Peak complete grant year is 2021 (8 grants) versus a trough of 4 in 2015. By volume, California sits between Beijing Wodong Tianjun Information Technology Co., Ltd. and Constellium Issoire.

California's three-year grant acceleration

California Expanded Metal Products Company shows 4 grants in 2022–2024 against only 17 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.
