FUN
Serial 75524115 · Principal Register
Live · Registered

Owner: Molecular Probes, Inc.
Class 001 -
Filed Jul 23, 1998
Registered Sep 07, 1999

The record shows that “FUN” is a live Principal Register trademark owned by Molecular Probes, Inc., a corporation organized in Oregon, and it covers “fluorescent chemicals for use in scientific research” in International Class 001; a similar name used for scientific‑research chemicals would create the closest record‑based concern, while uses in unrelated fields fall farther from the scope shown. The registration does not give the owner control over every possible use of the word “FUN.” The most recent meaningful event is the acceptance of the Section 8 (renewal) and Section 9 (declaration of continued use) filing on Oct 3 2019, which renewed the mark for a second ten‑year period. The prosecution history contains no oppositions, cancellations or court actions, so the supplied history shows no visible enforcement activity. I'd treat this as a meaningful concern if you plan a name in the same scientific‑chemical space, but the risk is lower for unrelated goods or services.

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.

Your name deserves a straight answer.
