Does more volume mean deeper claims for Harima?

Each dot is one of Harima’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). Harima’s own 9.3 claims/patent is at or below the 11.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Harima's grants concentrate

Harima Chemicals, Incorporated is a focused PatentsView assignee: 25 CPC subclasses with 53.1% of grants classified under B23K (Soldering OR UNSOLDERING; WELDING; Cladding OR Plating BY Soldering OR WELDING; Cutting BY Applying Heat Locally, e.g. Flame CUTTING; Working BY Laser Beam). Peak complete grant year is 2018 (6 grants) versus a trough of 1 in 2022. By volume, Harima sits between Herbert Waldmann GMBH & Co. KG and Hubbell Lighting, Inc..

Harima's three-year grant acceleration

Harima Chemicals, Incorporated shows 7 grants in 2022–2024 against only 11 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.
