What this record means
The record shows that FUN was a Principal Register trademark owned by SHULTON, INC., a New Jersey corporation, but the registration was cancelled on Dec 20, 1983 because the owner failed to file an acceptable Section 8 declaration, so the mark is no longer live. The only listed goods are “WOMEN'S COLOGNE” in International Class 3, meaning the closest area of concern for a similar name would be cosmetics, specifically fragrance products for women. The record does not give SHULTON, INC. control over every use of the word FUN in other categories or contexts. Because the mark was on the Principal Register and never moved to the Supplemental Register, there is no examination sequence to explain. The latest meaningful event is the Section 8 cancellation in 1983, and the supplied history shows no oppositions, cancellations by others, or court actions. I'd treat this as a modest concern if you plan a fragrance brand named FUN, but the risk is limited to that narrow cosmetic field.
