Does more volume mean deeper claims for Honbusankei?

Each dot is one of Honbusankei’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). Honbusankei’s own 19.4 claims/patent is ABOVE the 9.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Honbusankei's grants concentrate

Honbusankei Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 100% of grants classified under C01B (Non-metallic ELEMENTS; Compounds THEREOF; ; Metalloids OR Compounds Thereof NOT Covered BY Subclass C01c). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2015. By volume, Honbusankei sits between Holmatro B.V. and Hori Co., Ltd.

Honbusankei's three-year grant acceleration

Honbusankei Co., Ltd. shows 1 grants in 2022–2024 against only 1 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.
