Where China's grants concentrate

China International Marine Containers (GROUP) Co., Ltd. is a focused PatentsView assignee: 33 CPC subclasses with 53.8% of grants classified under B65D (Containers FOR Storage OR Transport OF Articles OR Materials, e.g. Bags, Barrels, Bottles, Boxes, Cans, Cartons, Crates, Drums, Jars, Tanks, Hoppers, Forwarding CONTAINERS; Accessories, Closures, OR F). Peak complete grant year is 2020 (6 grants) versus a trough of 1 in 2021. By volume, China sits between Caamtech, Inc. and CaptionCall, LLC.

China's three-year grant acceleration

China International Marine Containers (GROUP) Co., Ltd. shows 6 grants in 2022–2024 against only 12 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.
