What this shows Geron's Innovation Score is 47.9/100 (top 17% 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 Geron?

Each dot is one of Geron’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). Geron’s own 21.9 claims/patent is ABOVE the 12.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Geron's grants concentrate

Geron Corporation is a focused PatentsView assignee: 16 CPC subclasses with 57.8% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2017 (11 grants) versus a trough of 1 in 2023. By volume, Geron sits between Fortress Iron, LP and Hanmi Science Co., Ltd.

Geron's three-year grant acceleration

Geron Corporation shows 10 grants in 2022–2024 against only 9 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.
