Each dot is one of Greenfield’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). Greenfield’s own 11.1 claims/patent is ABOVE the 6.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Greenfield's grants concentrate

Greenfield World Trade, Inc. is a focused PatentsView assignee: 3 CPC subclasses with 40% of grants classified under A47J (Kitchen EQUIPMENT; Coffee MILLS; Spice MILLS; Apparatus FOR Making Beverages). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2020. By volume, Greenfield sits between Gradalis, Inc. and Guangdong Yingao Kitchen Utensils Co., Ltd..

Greenfield's three-year grant acceleration

Greenfield World Trade, Inc. shows 2 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.
