What this shows Kromek's Innovation Score is 31.8/100 (39th 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 Kromek?

Each dot is one of Kromek’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). Kromek’s own 18.1 claims/patent is ABOVE the 4.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Kromek's grants concentrate

Kromek Group. PLC is a focused PatentsView assignee: 9 CPC subclasses with 69.2% of grants classified under G01T (Measurement OF Nuclear OR X-radiation). Peak complete grant year is 2019 (6 grants) versus a trough of 1 in 2022. By volume, Kromek sits between Kohoku Kogyo Co., Ltd. and Kyb-ys Co., Ltd..

Kromek's three-year grant acceleration

Kromek Group. PLC shows 2 grants in 2022–2024 against only 11 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.
