What this shows Plasma-therm's Innovation Score is 35.4/100 (top 49% 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 Plasma-therm?

Each dot is one of Plasma-therm’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). Plasma-therm’s own 14.1 claims/patent is at or below the 17.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Plasma-therm's grants concentrate

Plasma-Therm LLC is a focused PatentsView assignee: 11 CPC subclasses with 90% of grants classified under H01L (Semiconductor Devices NOT Covered BY Class H10). Peak complete grant year is 2015 (8 grants) versus a trough of 1 in 2018. By volume, Plasma-therm sits between Poly Medicure Limited and Printed Energy Pty Ltd.

Plasma-therm's three-year grant acceleration

Plasma-Therm LLC shows 5 grants in 2022–2024 against only 10 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.
