Does more volume mean deeper claims for Century?

Each dot is one of Century’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Century’s own 9.3 claims/patent is at or below the 12.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Century's grants concentrate

Century Plastics, LLC is a focused PatentsView assignee: 18 CPC subclasses with 50% of grants classified under B29C (Shaping OR Joining OF PLASTICS; Shaping OF Material IN A Plastic State, NOT Otherwise Provided FOR; After-treatment OF THE Shaped Products, e.g. Repairing). Peak complete grant year is 2016 (8 grants) versus a trough of 1 in 2017. By volume, Century sits between Cantargia AB and Chapman/Leonard Studio Equipment, Inc..

Century's three-year grant acceleration

Century Plastics, LLC shows 1 grants in 2022–2024 against only 3 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.
