Does more volume mean deeper claims for OK?

Each dot is one of OK’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). OK’s own 14.5 claims/patent is ABOVE the 14.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where OK's grants concentrate

OK International, Inc. is a focused PatentsView assignee: 8 CPC subclasses with 84.6% 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 2020 (5 grants) versus a trough of 1 in 2018. By volume, OK sits between Obshchestvo S Ogranichennoy Otvetstvennost'yu “OBEDINENNAYA Kompaniya Rusal Inzhenerno-tekhnologicheskiy TSENTR” and Optotech Optikmaschinen GMBH.

OK's three-year grant acceleration

OK International, Inc. shows 2 grants in 2022–2024 against only 5 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.
