What this record means
The record shows that FUN is a cancelled registration – the Principal Register entry (Reg. 1261086) was cancelled on April 17, 1990 because the owner, Mexican Exporters, Inc., did not file a required Section 8 declaration, and the record is marked “dead.” The registration covered only one class, Class 030 (Staple Foods), specifically the good “Pasta,” so a later use of FUN for pasta or closely related food products would raise the most direct record‑based concern. The record does not give Mexican Exporters, Inc. control over every possible use of the word FUN; it is limited to the listed pasta goods. There is no Supplemental Register filing here, and the prosecution history simply moves from approval to registration and then to cancellation. The latest meaningful event is the Section 8 cancellation in 1990, and the supplied history shows no oppositions, cancellations, or other enforcement activity. I'd treat this as a moderate concern if you plan to market pasta under a similar name, but the risk is far lower for unrelated goods.
