What this shows Ntherma's Innovation Score is 27.0/100 (22nd percentile 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 Ntherma?

Each dot is one of Ntherma’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). Ntherma’s own 7.8 claims/patent is ABOVE the 6.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Ntherma's grants concentrate

Ntherma Corporation is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under C01B (Non-metallic ELEMENTS; Compounds THEREOF; ; Metalloids OR Compounds Thereof NOT Covered BY Subclass C01c). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2023. By volume, Ntherma sits between Novotec and NTT Security Holdings Corporation.

Ntherma's three-year grant acceleration

Ntherma Corporation shows 3 grants in 2022–2024 against only 2 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.
