Does more volume mean deeper claims for Silgan?

Each dot is one of Silgan’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). Silgan’s own 10.1 claims/patent is at or below the 15.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Silgan's grants concentrate

Silgan Plastics LLC is a focused PatentsView assignee: 11 CPC subclasses with 52.5% 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 2016 (7 grants) versus a trough of 1 in 2022. By volume, Silgan sits between Shenzhen Hello Tech Energy Co., Ltd and Somerset Therapeutics, LLC.

Silgan's three-year grant acceleration

Silgan Plastics LLC shows 3 grants in 2022–2024 against only 17 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.
