What this shows Topera's Innovation Score is 39.9/100 (top 37% 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 Topera?

Each dot is one of Topera’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). Topera’s own 31.1 claims/patent is ABOVE the 17.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Topera's grants concentrate

Topera Inc. is a focused PatentsView assignee: 9 CPC subclasses with 100% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2016 (9 grants) versus a trough of 2 in 2022. By volume, Topera sits between Taisei Kako Co., Ltd. and Twistlock Ltd..

Topera's three-year grant acceleration

Topera Inc. shows 2 grants in 2022–2024 against only 10 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.
