Goods text is quoted from the USPTO record and shortened where marked “…”. Classes listed are international classes. A dash (—) means no registration has issued.
Mark type matters. A standard-character mark covers the wording itself, in any font or style. A stylized or design (logo) mark is registered as shown, and how far it reaches to the same words in plain text is fact-specific. A trademark attorney can tell you how it applies to your design. USPTO mark descriptions:
Serial 77818908: The mark consists of The words 'Sunday Funday' (where a beer mug/glass is replacing what would perceived to be the 'U' in 'Funday'). The letters in 'Sunday Funday' are in yellow and the beer mug/glass consists of the colors brown and white.
About this check. This page lists only the 3 USPTO records shown above. We picked them from a limited sample of search results (the top 100 results per phrase search, when a common phrase can have thousands of related filings) and verified each one on its USPTO TSDR status page. Other filings, live or dead, may exist. Where this page says "none," it means none in the records we checked.
Shirts and apparel (class 25). The live registration covers shirts, hats, jerseys and shorts. Brunch, football and day-drinking shirts that say "Sunday Funday" overlap directly. It was renewed in 2021.
Stickers and paper (class 16). MHAN INC's Reg. No. 8433739 (registered Sept. 15, 2026) covers packaged kits with printed STEM teaching materials. That's a narrow description, not stickers, but it's still a live class 16 record for the exact phrase.
Dead filing. Sunday Funday, LLC's 2009 application for T-shirts (a logo with a beer mug replacing the "U" in "Funday") was abandoned in 2012.
Mugs and bags. None in the records we checked for classes 21 or 18.
Variants are starting points, not clearances. Any new wording can match a record we didn't list or a filing made after our check. Run every final phrase through a search before you list it.
One phrase is easy to look up. Hundreds of listings aren't. PhraseSafe checks the titles and tags in your Etsy or Shopify listings export against USPTO trademark records in merch classes and flags matches with status, class, owner and filing date. Starter scans up to 500 listings at a time. Pro adds a monthly new-filing check and daily status checks on marks you watch, with results shown on your PhraseSafe dashboard. Paid plans are activated with a license key.
