Lessons from the Fight Over the TWITTER® Name

If you have followed recent business or technology news, you may have seen headlines suggesting that the Twitter trademark might be “up for grabs.” That claim sounds shocking given the brand’s global recognition, but the dispute raises an important and very practical question for businesses of all sizes:

Can a trademark owner lose its rights simply by rebranding?

The short answer is no — not automatically. The longer answer, as illustrated by the ongoing Twitter/X dispute, is more nuanced and offers valuable guidance for brand owners navigating how name changes and brand refreshes may impact their trademark portfolios and legacy brands.

What’s Going On?

After Elon Musk rebranded Twitter as “X” in 2023, a startup called Operation Bluebird asserted that the TWITTER® and TWEET® trademarks were abandoned under U.S. trademark law and thus available for adoption by Operation Bluebird.

Operation Bluebird took two steps. First, it filed a petition with the U.S. Patent and Trademark Office’s Trademark Trial and Appeal Board (TTAB) seeking cancellation of several Twitter-related trademark registrations on abandonment grounds. Second, it launched a public-facing website promoting its plan to revive the Twitter name as a new social media platform.

In response, X Corp. (the company formerly known as Twitter) filed a federal trademark infringement lawsuit in Delaware. The company argues that it never abandoned the TWITTER brand and that Operation Bluebird’s actions constitute unlawful trademark infringement and unfair competition.

Use it or Lose it

Once abandoned, a mark falls into the public domain and is available for the first user to begin use of the mark as its own.

Under U.S. trademark law, a mark is deemed abandoned for nonuse when both of the following elements are met:

• Use of the mark has been discontinued (nonuse); and
• The trademark owner has no intent to resume use of the mark.

 Although simple on its face, application of this 2-part test is highly fact specific.

Why X Says It Still Owns TWITTER®

X Corp. contends that the TWITTER trademarks were never abandoned and points to several facts.

• The twitter.com domain remains active and continues to route users to X Corp.’s platform.
• The public still widely refers to X Corp.’s platform as “TWITTER,” reflecting ongoing consumer recognition and goodwill associating the TWITTER brands with X Corp.
• X Corp. has continued to police the TWITTER marks by objecting to unauthorized third-party use.

In other words, rebranding to “X” does not necessarily mean walking away from “TWITTER” as a trademark. Trademark law requires a mark owner to engage in bona fide commercial use of a mark. There is no requirement that a mark continue as the owner’s primary brand.

Why Operation Bluebird Thinks It Has a Case

Operation Bluebird’s position, while aggressive, is not frivolous. Its argument centers on the idea that the TWITTER brands were publicly and deliberately phased out, that the company encouraged users to stop using the TWITTER name, and that the marks no longer function as traditional source identifiers.

What Happens Next?

This dispute is likely to proceed on two parallel tracks in the TTAB and the Delaware federal court. The TTAB cancellation proceeding will focus on abandonment and registration validity, while the Delaware federal lawsuit will address trademark infringement and unfair competition. With respect to the abandonment issue, the TTAB applies a lower evidentiary standard for abandonment, requiring only that the challenger Operation Bluebird demonstrate abandonment by a preponderance of the evidence. In the Delaware federal district court, Operation Bluebird must meet a higher standard of clear and convincing evidence to prevail on its abandonment defense. Resolution could take months or longer, but these are cases to watch.

Why This Matters to Your Business

Even if your company does not own a “headline” brand, this dispute highlights several practical takeaways.

First, rebranding requires careful trademark planning. Companies should affirmatively decide what happens to legacy trademarks and document continued use or intent to resume use. Second, old brands can retain significant value long after they stop being front-and-center, particularly if consumers still recognize them. Third, high-profile or seemingly dormant brands often attract opportunistic cancellation actions and domain registrations.

Final Thoughts

The Twitter/X situation is a reminder that trademarks are living assets. They require maintenance, strategic thinking, and proactive enforcement. For businesses considering a rebrand, retiring a product name, or reviving an older mark, early trademark guidance can help prevent expensive disputes later.
