Does more volume mean deeper claims for Tenneco?
Each dot is one of Tenneco’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). Tenneco’s own 13.4 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 Tenneco's grants concentrate
Tenneco (SUZHOU) Emission System Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under F01N (Gas-flow Silencers OR Exhaust Apparatus FOR Machines OR Engines IN GENERAL; Gas-flow Silencers OR Exhaust Apparatus FOR Internal-combustion Engines). Peak complete grant year is 2019 (4 grants) versus a trough of 1 in 2022. By volume, Tenneco sits between Technoguard Inc. and THE Lightco Inc..
Tenneco's three-year grant acceleration
Tenneco (SUZHOU) Emission System Co., Ltd. shows 1 grants in 2022–2024 against only 9 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.
