Threads Software Limited says its lawyers wrote a snotogram to the Facebook and Instagram parent company saying that if Meta doesn't stop using the name Threads, it will seek an injunction from the courts.

The British company trademarked Threads in 2012 for its intelligent messaging hub, which can store a company's emails, tweets, and voice over internet protocol phone calls in a cloud database.

In a press release, it said it had declined the four offers that Meta's lawyers made to purchase its domain name "threads.app."

When Meta launched Threads, its social media app designed to compete with Elon Musk's X, the British company says it was removed from Facebook.

John Yardley, the managing director of Threads Software Limited, said the business "faces a serious threat from one of the largest technology companies in the world."

"We recognise that this is a classic 'David and Goliath' battle with Meta. And whilst they may think they can use whatever name they want, that does not give them the right to use the Threads brand name."
