Does more volume mean deeper claims for Chemo?

Each dot is one of Chemo’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). Chemo’s own 18.4 claims/patent is ABOVE the 10.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Chemo's grants concentrate

Chemo Research, S.L. is a focused PatentsView assignee: 7 CPC subclasses with 81.8% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2015. By volume, Chemo sits between Champion Laboratories, Inc. and China Academy OF Railway Sciences Corporation Ltd..

Chemo's three-year grant acceleration

Chemo Research, S.L. 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.
