What this shows PSG's Innovation Score is 45.5/100 (top 23% 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 PSG?

Each dot is one of PSG’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). PSG’s own 16.6 claims/patent is ABOVE the 10.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where PSG's grants concentrate

PSG California LLC is a focused PatentsView assignee: 7 CPC subclasses with 80% of grants classified under F04B (Positive-displacement Machines FOR LIQUIDS; Pumps). By volume, PSG sits between Proxene Tools Co., Ltd. and PST Sensors (PROPRIETARY) Limited.

PSG's three-year grant acceleration

PSG California LLC shows 3 grants in 2022–2024 against only 1 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.
