Does more volume mean deeper claims for K-fee?
Each dot is one of K-fee’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). K-fee’s own 12.7 claims/patent is ABOVE the 9.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where K-fee's grants concentrate
K-fee System GMBH is a focused PatentsView assignee: 11 CPC subclasses with 66.7% 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 2023 (10 grants) versus a trough of 3 in 2016. By volume, K-fee sits between IronRidge, Inc. and Kichler Lighting LLC.
K-fee's three-year grant acceleration
K-fee System GMBH shows 23 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.
