What this shows Eargo's Innovation Score is 38.3/100 (top 41% 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 Eargo?

Each dot is one of Eargo’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). Eargo’s own 21.6 claims/patent is ABOVE the 15.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Eargo's grants concentrate

Eargo, Inc. is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under H04R (Loudspeakers, Microphones, Gramophone Pick-ups OR Like Acoustic Electromechanical TRANSDUCERS; Deaf-aid SETS; Public Address Systems). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2015. By volume, Eargo sits between EL TORO.COM, LLC and Elobau GmbH & Co. KG.

Eargo's three-year grant acceleration

Eargo, Inc. shows 6 grants in 2022–2024 against only 7 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.
