X trademark abandonment ruling threatens legacy Twitter branding and logos

This ruling establishes a high bar for media companies attempting to warehouse legacy intellectual property after a corporate pivot. For streaming platforms undergoing consolidation or rebranding, the decision proves that 'formerly known as' tags may preserve a primary name but will not protect secondary assets like logos or specific feature names if they are relegated to outdated help centers. The broader ecosystem must now view dormant trademarks as strategic targets for competitors seeking to clear market space. Industry observers should monitor whether X files further evidence of commercial exploitation to prevent the full revocation of its remaining Twitter-related registrations.

The X ruling follows a well-established legal principle that trademark protection requires active commercial use, not merely registration. In the UK, section 46 of the Trade Marks Act 1994 permits revocation where a mark has not been put to genuine use within five years of registration, with the burden falling on the trademark owner to prove genuine use or establish proper reasons for non-use. The Macfarlanes analysis identifies corporate rebrands as a particularly high-risk inflection point, noting that legacy marks falling out of active use after a rebrand are especially vulnerable to revocation challenges from competitors seeking to clear market space.

The most prominent precedent for a major brand losing trademark protection through non-use is the McDonald's BIG MAC case. The EU General Court held that McDonald's failed to establish genuine use of its BIG MAC trademark in respect of chicken sandwiches and restaurant services, revoking protection for those categories. The court emphasized that genuine use cannot be proved by probabilities or presumptions but must be demonstrated by solid and objective evidence of actual and sufficient use on the market. McDonald's had produced advertising posters and Facebook screenshots, but the evidence failed to show quantities, regularity, or pricing of goods distributed, demonstrating that even globally recognized brands face revocation when evidence quality is insufficient.

Legal practitioners have noted that the X case and the BIG MAC decision together illustrate a consistent judicial standard across jurisdictions. Bird & Bird published guidance on preventing trademark revocation for non-use following the BIG MAC ruling, advising brand owners to maintain contemporaneous evidence including dated sales invoices, promotional materials showing the mark as used, and photographs of branded goods. For streaming and media companies undergoing rebrands or consolidations, the pattern across these cases signals that dormant IP portfolios require active monitoring and documented commercial deployment to withstand challenges from competitors deploying non-use revocation as a strategic tool.
