One in the eye for anyone who wants to use the word should’ve. Specsavers have made an application to register the word as a trademark in the UK. The company already has the phrase “Should’ve gone to Specsavers” registered which is reasonable.
Trademarks have to be distinguishable to be registrable. Sometimes applications will be made using a particular styling of a word (an unusual font or combined logo). This application is just for the word alone. The trademark examiners had no issue with the application and it now at publication stage so well on its way to being registered trade mark before Christmas. Should’ve not mentioned that C word. Get using should’ve whilst you can.
