What this shows Dioxide's Innovation Score is 38.0/100 (top 42% 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 Dioxide?

Each dot is one of Dioxide’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). Dioxide’s own 16.7 claims/patent is at or below the 18.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Dioxide's grants concentrate

Dioxide Materials, Inc. is a focused PatentsView assignee: 19 CPC subclasses with 82.8% of grants classified under C25B (Electrolytic OR Electrophoretic Processes FOR THE Production OF Compounds OR NON-METALS; Apparatus Therefor). Peak complete grant year is 2018 (7 grants) versus a trough of 1 in 2021. By volume, Dioxide sits between Daechang Seat Co., LTD-Dongtan and Elbit Systems Land AND C4I Ltd..

Dioxide's three-year grant acceleration

Dioxide Materials, Inc. shows 1 grants in 2022–2024 against only 8 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.
