Does more volume mean deeper claims for Nemak?
Each dot is one of Nemak’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). Nemak’s own 13.6 claims/patent is ABOVE the 7.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Nemak's grants concentrate
Nemak, S.A.B. de C.V. is a focused PatentsView assignee: 20 CPC subclasses with 50% of grants classified under B22D (Casting OF METALS; Casting OF Other Substances BY THE Same Processes OR Devices). Peak complete grant year is 2020 (5 grants) versus a trough of 1 in 2017. By volume, Nemak sits between Nanchang Hangkong University and Ningbo Shijia Cleaning Tools Co., Ltd..
Nemak's three-year grant acceleration
Nemak, S.A.B. de C.V. shows 5 grants in 2022–2024 against only 10 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.
