Does more volume mean deeper claims for Fairfield?

Each dot is one of Fairfield’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). Fairfield’s own 15.4 claims/patent is ABOVE the 14.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Fairfield's grants concentrate

Fairfield Manufacturing Company, Inc. is a focused PatentsView assignee: 21 CPC subclasses with 60% of grants classified under F16H (Gearing). Peak complete grant year is 2018 (5 grants) versus a trough of 1 in 2017. By volume, Fairfield sits between Evenflo Company, Inc. and Fleece Performance Engineering, Inc..

Fairfield's three-year grant acceleration

Fairfield Manufacturing Company, Inc. shows 4 grants in 2022–2024 against only 5 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.
