ONESerial 99590109 · Principal Register
Pending · Under Examination
Owner: KLA Corporation
Class 007 -
Class 009 - Electrical & Scientific Apparatus
Filed Jan 12, 2026
The record shows a live, pending application for the mark ONE owned by KLA Corporation, a California corporation, filed on Jan 12 2026 and currently under examination on the Principal Register; the most recent status entry is “Review prior to publication completed” dated Aug 28 2026, and the mark is slated for publication for opposition on Sep 15 2026. The application covers semiconductor manufacturing machines (load ports) in class 007 and a range of computer hardware and software related to metrology equipment, semiconductor devices, and communication between load ports and wafer sensors in class 009, so a similar name used in those high‑tech semiconductor contexts would present the closest record‑based concern. The record does not give KLA control over every possible use of the word ONE outside those described fields. The prosecution history shows an office‑action and a response but no supplemental‑register filing, and there are no oppositions, cancellations or other enforcement actions noted. I'd treat this as a meaningful concern if you plan a name in the same semiconductor‑equipment arena.
Full event history, owner details, and verdict inside.
The way I'd use it, honestly, is as the thing you attach when a bank, a marketplace, or a co-founder asks "are we clear on the name". It answers in one page.
