Does more volume mean deeper claims for Essen?
Each dot is one of Essen’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). Essen’s own 1.9 claims/patent is at or below the 14.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Essen's grants concentrate
Essen Tech Co., Ltd. is a focused PatentsView assignee: 1 CPC subclasses with 14.3% of grants classified under F16L (PIPES; Joints OR Fittings FOR PIPES; Supports FOR Pipes, Cables OR Protective TUBING; Means FOR Thermal Insulation IN General). Peak complete grant year is 2023 (7 grants) versus a trough of 1 in 2022. By volume, Essen sits between EPC Product LLC and Everysight Ltd..
Essen's three-year grant acceleration
Essen Tech Co., Ltd. shows 8 grants in 2022–2024 against only 6 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.
