What this shows Keronite's Innovation Score is 30.8/100 (35th percentile 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 Keronite?

Each dot is one of Keronite’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). Keronite’s own 11.2 claims/patent is at or below the 13.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Keronite's grants concentrate

Keronite International Limited is a focused PatentsView assignee: 10 CPC subclasses with 100% of grants classified under C25D (Processes FOR THE Electrolytic OR Electrophoretic Production OF COATINGS; ELECTROFORMING; Apparatus Therefor). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2016. By volume, Keronite sits between Kelvin Thermal Energy Inc. and Kewaunee Scientific Corporation.

Keronite's three-year grant acceleration

Keronite International Limited shows 1 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.
