Shanghai Conant Optical Co., Ltd is a focused PatentsView assignee: 10 CPC subclasses with 85.7% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2023. By volume, Shanghai sits between Sexy Back BRA, LLC and Shanghai Hongchen Household Wares Co., Ltd..
Shanghai Conant Optical Co., Ltd shows 3 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.
