What this shows Niterra's Innovation Score is 60.1/100 (top 4% 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.

Where Niterra's grants concentrate

Niterra Co., Ltd. is a focused PatentsView assignee: 38 CPC subclasses with 35% of grants classified under H01T (Spark GAPS; Overvoltage Arresters Using Spark GAPS; Sparking PLUGS; Corona DEVICES; Generating Ions TO BE Introduced Into Non-enclosed Gases). Peak complete grant year is 2024 (35 grants) versus a trough of 3 in 2023. By volume, Niterra sits between Lockheed Martin Energy, LLC and Open Text S.A..

Niterra's three-year grant acceleration

Niterra Co., Ltd. shows 38 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.
