Threads Software Limited has issued a 30-day ultimatum to Meta to stop using the name "Threads" in the United Kingdom (UK) due to their ownership of the trademark.

Threads Software Limited has communicated through legal channels with the parent company of Facebook and Instagram. If Meta fails to comply by discontinuing the use of the name Threads, the British company states its intention to seek a court injunction.

Threads Software Limited secured the trademark for "Threads" in 2012 designating it for their intelligent messaging hub.

This hub is capable of storing a company's emails, tweets, and voice over internet protocol (VoIP) phone calls in a cloud-based database.

The British company revealed that it had rejected four purchase offers from Meta's legal team regarding their domain name "threads.app".

However, when Meta introduced its social media app called Threads intended to compete with Elon Musk's platform, it resulted in the British company being removed from Facebook.

The Managing Director of Threads Software Limited John Yardley expressed concerns about the significant threat his business faces from one of the world's largest technology companies.

Meta launched its Threads app in July, which coincided with Elon Musk's decision to impose a temporary limit on the number of tweets users could view.

The Threads app rapidly achieved the status of becoming the fastest app to attain 100 million users, accomplishing this feat in just five days. Its integration with Instagram played a role in this success.

By the end of July, Mark Zuckerberg acknowledged that over half of Threads' users had discontinued their usage of the platform. Since then, the app has introduced new features and maintained an active user base of 120 million users in the current month.

John Yardley characterized the situation as a classic "David and Goliath" battle with Meta, asserting that their size should not grant them the privilege to use the Threads brand name without consequence.

Meta has not yet responded to a request for comment from Insider.
