What this shows Salix's Innovation Score is 37.1/100 (top 44% 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 Salix?

Each dot is one of Salix’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). Salix’s own 14.4 claims/patent is ABOVE the 13.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Salix's grants concentrate

Salix Pharmaceuticals, Inc. is a focused PatentsView assignee: 12 CPC subclasses with 87.8% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2015 (8 grants) versus a trough of 1 in 2021. By volume, Salix sits between Southern Taiwan University OF Science AND Technology and SpringWorks Therapeutics, Inc..

Salix's three-year grant acceleration

Salix Pharmaceuticals, Inc. shows 5 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.
