Does more volume mean deeper claims for Zenith?
Each dot is one of Zenith’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). Zenith’s own 18.4 claims/patent is ABOVE the 16.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Zenith's grants concentrate
Zenith Epigenetics Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 92% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2019 (7 grants) versus a trough of 1 in 2015. By volume, Zenith sits between XDI Holdings, LLC and Zendesk, Inc..
Zenith's three-year grant acceleration
Zenith Epigenetics Ltd. shows 3 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.
