What this shows Kromek's Innovation Score is 44.8/100 (top 25% 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 19.8 claims/patent is ABOVE the 11.9 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 Limited is a focused PatentsView assignee: 14 CPC subclasses with 54.5% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2015 (5 grants) versus a trough of 1 in 2018. By volume, Kromek sits between Joslin Diabetes Center and Kadmon Corporation, LLC.

Kromek's three-year grant acceleration

Kromek Limited shows 4 grants in 2022–2024 against only 3 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.
