What this shows Proterra's Innovation Score is 52.3/100 (top 10% 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 Proterra?

Each dot is one of Proterra’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). Proterra’s own 20.1 claims/patent is ABOVE the 17.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Proterra's grants concentrate

Proterra Operating Company, Inc. is a focused PatentsView assignee: 12 CPC subclasses with 77.8% of grants classified under Y02T (Climate Change Mitigation Technologies Related TO Transportation). Peak complete grant year is 2022 (5 grants) versus a trough of 4 in 2023. By volume, Proterra sits between Proserv Gilmore Valve LLC and Pupil Labs GmbH.

Proterra's three-year grant acceleration

Proterra Operating Company, Inc. shows 9 grants in 2022–2024 against only 0 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.
