Where Weihai's grants concentrate

Weihai Hualing Opto-electronics Co., Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 63.6% of grants classified under G07D (HANDLING OF COINS OR VALUABLE PAPERS, e.g. TESTING, SORTING BY DENOMINATIONS, COUNTING, DISPENSING, CHANGING OR DEPOSITING). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2017. By volume, Weihai sits between W. Morrison Consulting Group Inc. and Wholeknit International Co., Ltd..

Weihai's three-year grant acceleration

Weihai Hualing Opto-electronics Co., Ltd. shows 5 grants in 2022–2024 against only 4 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.
