Where Nanotechceramics's grants concentrate

Nanotechceramics Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 66.7% of grants classified under A43B (Characteristic Features OF FOOTWEAR; Parts OF Footwear). By volume, Nanotechceramics sits between Nanjing Reclaimer Environmental Teknik Co., Ltd and Naura Akrion, Inc..

Nanotechceramics's three-year grant acceleration

Nanotechceramics Co., Ltd. shows 2 grants in 2022–2024 against only 1 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.
