What this shows Niigon's Innovation Score is 37.0/100 (top 45% 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 Niigon?

Each dot is one of Niigon’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). Niigon’s own 22.5 claims/patent is ABOVE the 3.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Niigon's grants concentrate

Niigon Machines Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under B29C (Shaping OR Joining OF PLASTICS; Shaping OF Material IN A Plastic State, NOT Otherwise Provided FOR; After-treatment OF THE Shaped Products, e.g. Repairing). Peak complete grant year is 2022 (5 grants) versus a trough of 1 in 2020. By volume, Niigon sits between Newcastle Innovation Limited and Ningbo Liyang NEW Material Company Limited.

Niigon's three-year grant acceleration

Niigon Machines Ltd. shows 6 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.
