Does more volume mean deeper claims for Hamanakodenso?

Each dot is one of Hamanakodenso’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). Hamanakodenso’s own 9.7 claims/patent is ABOVE the 8.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Hamanakodenso's grants concentrate

Hamanakodenso Co., Ltd. is a focused PatentsView assignee: 22 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 2021 (10 grants) versus a trough of 1 in 2016. By volume, Hamanakodenso sits between Gala Industies, Inc. and Hirosaki University.

Hamanakodenso's three-year grant acceleration

Hamanakodenso Co., Ltd. shows 5 grants in 2022–2024 against only 16 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.
