Does more volume mean deeper claims for Ultragenyx?

Each dot is one of Ultragenyx’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). Ultragenyx’s own 17.6 claims/patent is ABOVE the 14.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Ultragenyx's grants concentrate

Ultragenyx Pharmaceutical Inc. is a focused PatentsView assignee: 10 CPC subclasses with 68% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2016 (4 grants) versus a trough of 1 in 2015. By volume, Ultragenyx sits between University OF Durham and University of Waterloo.

Ultragenyx's three-year grant acceleration

Ultragenyx Pharmaceutical Inc. shows 8 grants in 2022–2024 against only 6 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.
