Does more volume mean deeper claims for Carter?

Each dot is one of Carter’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). Carter’s own 13.6 claims/patent is at or below the 16.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Carter's grants concentrate

Carter Fuel Systems, LLC is a focused PatentsView assignee: 17 CPC subclasses with 50% of grants classified under F02M (Supplying Combustion Engines IN General With Combustible Mixtures OR Constituents Thereof). Peak complete grant year is 2015 (5 grants) versus a trough of 1 in 2017. By volume, Carter sits between Capital Microelectronics Co., Ltd. and Cellares Corporation.

Carter's three-year grant acceleration

Carter Fuel Systems, LLC shows 1 grants in 2022–2024 against only 3 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.
