What this record means
The record shows that the mark FUN was registered on the Principal Register to Ecolab Inc., a Delaware corporation, but the registration was cancelled on November 21, 2016 because the owner failed to file an acceptable Section 8 declaration, so the mark is now dead. The only listed goods are “ALL PURPOSE SOAP” in International Class 3, with a first use date of August 16, 1944; a later filing that uses the same word for cleaning products would run into the closest record‑based concern, while uses in unrelated categories such as software or apparel would be farther from the scope shown here. The history contains no oppositions, cancellations by a third party, or other enforcement actions, so the supplied file shows no visible enforcement activity. The most recent meaningful event is the Section 8 cancellation in 2016. I'd treat this as a moderate concern if you plan a cleaning‑product brand with the same name, because the cancelled registration still signals prior use in that space.
