What this shows Photothermal's Innovation Score is 56.2/100 (top 6% 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 Photothermal?

Each dot is one of Photothermal’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). Photothermal’s own 26.2 claims/patent is ABOVE the 14.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Photothermal's grants concentrate

Photothermal Spectroscopy Corp. is a focused PatentsView assignee: 15 CPC subclasses with 100% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2024 (5 grants) versus a trough of 1 in 2020. By volume, Photothermal sits between Peratch Holdco Limited and Primera Technology, Inc..

Photothermal's three-year grant acceleration

Photothermal Spectroscopy Corp. shows 10 grants in 2022–2024 against only 4 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.
