What this shows Picosun's Innovation Score is 60.6/100 (top 3% 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 Picosun?

Each dot is one of Picosun’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). Picosun’s own 14.6 claims/patent is ABOVE the 11.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Picosun's grants concentrate

Picosun Oy is a focused PatentsView assignee: 27 CPC subclasses with 91.7% of grants classified under C23C (Coating Metallic MATERIAL; Coating Material With Metallic MATERIAL; Surface Treatment OF Metallic Material BY Diffusion Into THE Surface, BY Chemical Conversion OR SUBSTITUTION; Coating BY Vacuum Evap). Peak complete grant year is 2024 (10 grants) versus a trough of 2 in 2017. By volume, Picosun sits between Perftech, Inc. and Rhino Rack Australia PTY Limited.

Picosun's three-year grant acceleration

Picosun Oy shows 25 grants in 2022–2024 against only 7 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.
