What this shows Dolphin's Innovation Score is 49.4/100 (top 15% 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 Dolphin?

Each dot is one of Dolphin’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). Dolphin’s own 14.4 claims/patent is ABOVE the 10.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Dolphin's grants concentrate

Dolphin Fluidics S.R.L. is a focused PatentsView assignee: 14 CPC subclasses with 75% of grants classified under F16K (VALVES; TAPS; COCKS; ACTUATING-FLOATS; Devices FOR Venting OR Aerating). Peak complete grant year is 2018 (2 grants) versus a trough of 1 in 2017. By volume, Dolphin sits between Dm3d Technology, LLC and Dongguan Lianrun Lighting Co., Ltd..

Dolphin's three-year grant acceleration

Dolphin Fluidics S.R.L. shows 3 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.
