Does more volume mean deeper claims for Sauna?

Each dot is one of Sauna’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). Sauna’s own 13.8 claims/patent is ABOVE the 13.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Sauna's grants concentrate

Sauna Works Inc. is a focused PatentsView assignee: 5 CPC subclasses with 87.5% of grants classified under A61H (Physical Therapy Apparatus, e.g. Devices FOR Locating OR Stimulating Reflex Points IN THE BODY; Artificial RESPIRATION; MASSAGE; Bathing Devices FOR Special Therapeutic OR Hygienic Purposes OR Specifi). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2017. By volume, Sauna sits between Salto Systems, S.L. and Scott & White Healthcare.

Sauna's three-year grant acceleration

Sauna Works Inc. shows 6 grants in 2022–2024 against only 5 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.
