What this shows Liminal's Innovation Score is 29.1/100 (29th 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 Liminal?

Each dot is one of Liminal’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). Liminal’s own 20.0 claims/patent is ABOVE the 8.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Liminal's grants concentrate

Liminal BioSciences Limited is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2020. By volume, Liminal sits between Lighthouse Worldwide Solutions and Linhai Meiyang Parasol Industry Co., Ltd.

Liminal's three-year grant acceleration

Liminal BioSciences Limited shows 1 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.
