What this shows Bromine's Innovation Score is 43.5/100 (top 28% 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 Bromine?

Each dot is one of Bromine’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). Bromine’s own 12.1 claims/patent is ABOVE the 12.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Bromine's grants concentrate

Bromine Compounds Ltd. is a focused PatentsView assignee: 28 CPC subclasses with 37.5% of grants classified under C09K (Materials FOR Miscellaneous Applications, NOT Provided FOR Elsewhere). Peak complete grant year is 2016 (10 grants) versus a trough of 1 in 2022. By volume, Bromine sits between Basf Enzymes LLC and BreathableBaby, LLC.

Bromine's three-year grant acceleration

Bromine Compounds Ltd. shows 7 grants in 2022–2024 against only 10 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.
