Apple fans in Switzerland could be waiting until December to get their hands on the Cupertino company’s first wearable due to a 1985 patent that prevents it from selling an Apple-branded watch in the country.

Apple cannot launch a watch that uses the image of an apple or the word “apple,” according to a report from Swiss broadcaster RTS, which cites a document from the Swiss Federal Institute of Intellectual Property that was published by Business Montres & Joaillerie magazine.

However, the patent, which belongs to William Longe, owner of the Leonard watch brand, is set to expire on December 5 of this year, at which point Apple would be free to launch the Apple Watch without infringing any rights.

Apple hasn’t actually announced an Apple Watch launch date for Switzerland yet, but the device will make its debut in other European countries — as well as the U.S., Australia, Canada, China, and Japan — on April 24.

Apple did not respond to a request for comment from Reuters, so we’ll have to wait and see how it handles a Switzerland. It’s possible the company may reach an agreement with Longe to sell the Watch early, but it could just keep fans waiting until December instead.
