What this shows Clearflow's Innovation Score is 41.3/100 (top 33% 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 Clearflow?

Each dot is one of Clearflow’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). Clearflow’s own 23.1 claims/patent is ABOVE the 16.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Clearflow's grants concentrate

ClearFlow, Inc. is a focused PatentsView assignee: 7 CPC subclasses with 84.2% of grants classified under A61M (Devices FOR Introducing Media Into, OR Onto, THE Body ; Devices FOR Transducing Body Media OR FOR Taking Media From THE Body ; Devices FOR Producing OR Ending Sleep OR Stupor). Peak complete grant year is 2024 (5 grants) versus a trough of 1 in 2015. By volume, Clearflow sits between Cheng Shin Rubber Industrial Co., Ltd. and Congruens Group, LLC.

Clearflow's three-year grant acceleration

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