What this shows Drtech's Innovation Score is 35.6/100 (top 49% 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 Drtech?

Each dot is one of Drtech’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). Drtech’s own 11.4 claims/patent is ABOVE the 6.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Drtech's grants concentrate

Drtech Corporation is a focused PatentsView assignee: 5 CPC subclasses with 50% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2016. By volume, Drtech sits between Dragonfruit AI, Inc and DSilo Inc..

Drtech's three-year grant acceleration

Drtech Corporation shows 2 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.
