Quark Biosciences Taiwan, Inc. is a focused PatentsView assignee: 2 CPC subclasses with 77.8% of grants classified under C12Q (Measuring OR Testing Processes Involving Enzymes, Nucleic Acids OR Microorganisms ; Compositions OR Test Papers THEREFOR; Processes OF Preparing Such COMPOSITIONS; Condition-responsive Control IN Micr). Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2023. By volume, Quark sits between Qualitas Manufacturing Incorporated and QuinTron Instrument Company, Inc..

Quark's three-year grant acceleration

Quark Biosciences Taiwan, Inc. shows 1 grants in 2022–2024 against only 8 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.
