What this shows Evofem's Innovation Score is 45.8/100 (top 22% 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 Evofem?

Each dot is one of Evofem’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). Evofem’s own 20.0 claims/patent is ABOVE the 10.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Evofem's grants concentrate

Evofem, Inc. is a focused PatentsView assignee: 4 CPC subclasses with 100% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2017. By volume, Evofem sits between Eurotrol B.V. and Evox Therapeutics Ltd.

Evofem's three-year grant acceleration

Evofem, Inc. shows 4 grants in 2022–2024 against only 1 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.
