Does more volume mean deeper claims for Federal?

Each dot is one of Federal’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). Federal’s own 13.1 claims/patent is ABOVE the 12.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Federal's grants concentrate

Federal Lock Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 90% of grants classified under E05B (LOCKS; Accessories THEREFOR; Handcuffs). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2015. By volume, Federal sits between Fundacio Privada Institut DE Recerca DE LA SIDA—CAIXA and First Ammonia Motors, Inc..

Federal's three-year grant acceleration

Federal Lock Co., Ltd. shows 3 grants in 2022–2024 against only 2 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.
