What this shows Schott's Innovation Score is 36.8/100 (top 45% 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 Schott?

Each dot is one of Schott’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). Schott’s own 12.8 claims/patent is at or below the 15.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Schott's grants concentrate

Schott Japan Corporation is a focused PatentsView assignee: 14 CPC subclasses with 38.1% of grants classified under H01H (Electric SWITCHES; RELAYS; SELECTORS; Emergency Protective Devices). Peak complete grant year is 2019 (5 grants) versus a trough of 2 in 2018. By volume, Schott sits between Sakura Finetek Japan Co., Ltd. and Seyond, Inc..

Schott's three-year grant acceleration

Schott Japan Corporation shows 7 grants in 2022–2024 against only 9 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.
