What this shows Bulk's Innovation Score is 32.8/100 (42nd 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 Bulk?

Each dot is one of Bulk’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). Bulk’s own 20.5 claims/patent is ABOVE the 15.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Bulk's grants concentrate

Bulk Chemicals is a focused PatentsView assignee: 4 CPC subclasses with 100% of grants classified under C23C (Coating Metallic MATERIAL; Coating Material With Metallic MATERIAL; Surface Treatment OF Metallic Material BY Diffusion Into THE Surface, BY Chemical Conversion OR SUBSTITUTION; Coating BY Vacuum Evap). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2016. By volume, Bulk sits between Bruegmann USA, Inc. and Butler's Brand, Inc..

Bulk's three-year grant acceleration

Bulk Chemicals shows 1 grants in 2022–2024 against only 0 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.
