What this shows Nanofilm's Innovation Score is 46.7/100 (top 20% 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 Nanofilm?

Each dot is one of Nanofilm’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). Nanofilm’s own 17.7 claims/patent is ABOVE the 17.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Nanofilm's grants concentrate

Nanofilm Technologies International Limited is a focused PatentsView assignee: 7 CPC subclasses with 100% 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 (4 grants) versus a trough of 2 in 2023. By volume, Nanofilm sits between Nano Vation Therapeutics Inc. and Nantong Schmidt Opto-Electrical Technology Co. Ltd..

Nanofilm's three-year grant acceleration

Nanofilm Technologies International Limited shows 6 grants in 2022–2024 against only 0 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.
