What this shows Diamond's Innovation Score is 33.7/100 (45th 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 Diamond?

Each dot is one of Diamond’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). Diamond’s own 18.7 claims/patent is ABOVE the 16.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Diamond's grants concentrate

Diamond Products Limited is a focused PatentsView assignee: 6 CPC subclasses with 71.4% of grants classified under B28D (Working Stone OR Stone-like Materials). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2018. By volume, Diamond sits between Diageo Brands B.V. and Digital Surgery Systems, Inc..

Diamond's three-year grant acceleration

Diamond Products 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.
