What this shows Ningxia's Innovation Score is 30.6/100 (35th 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 Ningxia?

Each dot is one of Ningxia’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). Ningxia’s own 11.0 claims/patent is ABOVE the 6.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Ningxia's grants concentrate

Ningxia Orient Tantalum Industry Co., Ltd is a focused PatentsView assignee: 13 CPC subclasses with 77.8% of grants classified under B22F (Working Metallic POWDER; Manufacture OF Articles From Metallic POWDER; Making Metallic Powder ; Apparatus OR Devices Specially Adapted FOR Metallic Powder). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2015. By volume, Ningxia sits between Ningbo Somle Audio-visual Technology Co., Ltd and Nippon Yttrium Co., Ltd..

Ningxia's three-year grant acceleration

Ningxia Orient Tantalum Industry Co., Ltd shows 1 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.
