Does more volume mean deeper claims for Knorr-bremse?

Each dot is one of Knorr-bremse’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). Knorr-bremse’s own 13.3 claims/patent is at or below the 13.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Knorr-bremse's grants concentrate

Knorr-Bremse AG is a focused PatentsView assignee: 19 CPC subclasses with 50% of grants classified under B61D (Body Details OR Kinds OF Railway Vehicles). Peak complete grant year is 2018 (4 grants) versus a trough of 1 in 2016. By volume, Knorr-bremse sits between Key-Pak Technologies, LLC and Kongsberg Defence & Aerospace AS.

Knorr-bremse's three-year grant acceleration

Knorr-Bremse AG shows 3 grants in 2022–2024 against only 2 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.
