Sierra Mist lawsuit: PepsiCo Sent a Cease and Desist Over a TikToker’s Name

PepsiCo sent a cease and desist letter to TikTok content creator Cierra Mistt, a flight attendant with millions of followers, alleging that her online name was confusingly similar to the company’s lemon-lime soda Sierra Mist. What followed was a viral trademark dispute that spread across TikTok, YouTube, and Reddit, with the influencer publicly claiming she had beaten one of the world’s largest beverage companies in a legal fight.

No court filing has been publicly confirmed. PepsiCo has not commented. The dispute remained private, resolved, according to Cierra Mistt herself, “amicably.” The controversy is closed in any formal legal sense. What it leaves behind is a genuinely instructive case about how trademark law applies to personal online brands, what corporations can and cannot demand, and why the real reason PepsiCo retired Sierra Mist had nothing to do with an influencer.

Sierra Mist Lawsuit Timeline and Updates

1999 — Sierra Mist Launches as a Sprite Rival

PepsiCo introduces Sierra Mist in 1999, positioning the lemon-lime soda as its answer to Coca-Cola’s Sprite. The strategy is straightforward: Pepsi needs a citrus product in a category Sprite dominates. Sierra Mist launches with significant marketing support and genuine consumer interest.

That early momentum never fully converts into market share. Sprite holds a commanding position in the lemon-lime category. Sierra Mist trails throughout its entire existence, never threatening Sprite’s dominance in any sustained way.

2010–2018 — A Brand That Cannot Find Itself

PepsiCo attempts to revive Sierra Mist with a series of name changes and formula adjustments. In 2010, the product becomes Sierra Mist Natural, signaling a shift to natural sweeteners. That name disappears by 2013. By 2015, the company returns to high-fructose corn syrup and renames the drink Mist Twist. In 2018, it goes back to Sierra Mist.

Industry analysts are not kind. GlobalData managing director Neil Saunders describes the brand to CNN as a “confused” product that looks like “an imitation of Sprite.” The Mist Twist detour, he says, was “pointless” because it confused consumers further. The rebranding cycles signal a company that knows the product is failing but cannot find a fix.

2022 — Sales Hit Rock Bottom

Data from Beverage Digest, reported by CNN, shows Sierra Mist’s share of the soda market barely exceeding a tenth of 1 percent in 2022 after years of consecutive decline. Sprite holds approximately 8 percent of the same market over that period and is growing. Internal PepsiCo marketing acknowledges that the demand for lemon-lime sodas has never been greater. The brand is simply not capturing any of it.

In July 2022, food blogger SodaSeekers reports that PepsiCo has purchased a new domain name for an unannounced lemon-lime product. In August 2022, PepsiCo files a trademark application with the U.S. Patent and Trademark Office (USPTO) for the name “Starry.” The decision to retire Sierra Mist is already made, months before anyone hears of Cierra Mistt.

January 2023 — PepsiCo Discontinues Sierra Mist, Launches Starry

PepsiCo officially discontinues Sierra Mist in January 2023 and rolls out Starry as its replacement. The new drink targets Generation Z with a fresh visual identity, a high-citrus flavor profile, and a marketing campaign built on social media. PepsiCo’s Chief Marketing Officer Greg Lyons describes the launch as a chance to “give people a choice in an area that’s been dominated by one brand for years.”

Starry contains no caffeine, available in Regular and Zero-Sugar varieties, and its slogan “Starry Hits Different” openly adopts Gen Z vernacular. PepsiCo files the Starry trademark in August 2022 and the product hits shelves in January 2023. The rebrand is a proactive strategic move. No lawsuit, no court order, no influencer drove it.

February 2023 — Cierra Mistt Posts About Pepsi on TikTok

Within days of Sierra Mist disappearing from shelves, TikTok creator Cierra Mistt posts a video captioned: “the REAL reason sierra mist is now starry (for legal reasons ‘the conflict was amicably resolved’).” The video spreads rapidly. Her implication is clear: she, a content creator with millions of followers, forced a billion-dollar corporation to retire a decades-old brand.

Cierra Mistt says she has used her name since the days of AOL Instant Messenger, long before she became a known creator. She says PepsiCo sent her a cease and desist letter claiming her online persona infringed the Sierra Mist trademark. Her version of events: she discovered that certain Sierra Mist trademark registrations had lapsed, countered aggressively, and PepsiCo backed down. The conflict, she says, ended in her favor.

July 2023 — YouTube Video Escalates the Story

Cierra Mistt posts a longer YouTube video in July 2023, telling viewers that PepsiCo had accused her of trademark infringement. She again states she cannot share full details due to legal reasons. She ends by strongly implying she won. The video adds fuel to a narrative that is already circulating widely, with many online commentators treating her account as confirmed fact.

PepsiCo does not respond publicly. No statement, no denial, no confirmation. The company’s silence allows the story to build unchallenged across creator communities and consumer forums.

2023–2024 — Fact-Checkers Push Back

Legal publications including Tech and Media Law and Stemer Law analyze the public record. Their findings are consistent: no lawsuit has been filed in any federal or state court. USPTO records show PepsiCo’s Sierra Mist trademark registrations remain active. The claim that Cierra Mistt acquired trademark rights to “Sierra Mist” and forced a rebrand finds no support in public filings.

The trademark filing timeline tells a clean story. PepsiCo files for the Starry trademark in August 2022. Cierra Mistt’s public statements emerge in February 2023, after Starry is already in stores. Reverse-engineering a brand decision from a trademark dispute that post-dates the decision does not hold up to scrutiny.

Present — A Private Resolution, No Public Case

As of 2026, no court records confirm a lawsuit between PepsiCo and Cierra Mistt. The dispute, if one existed beyond the initial cease and desist letter, was resolved privately. Cierra Mistt has not released documentation. PepsiCo has not commented. The public record consists entirely of the creator’s own social media posts and the absence of any court filing to corroborate them.

What Actually Happened: The Trademark Analysis

Trademark law protects names, words, and logos that help consumers identify products. When a new brand or personal name resembles an established mark closely enough to cause consumer confusion, the trademark holder can send a cease and desist or file an infringement claim.

PepsiCo’s position was straightforward: “Cierra Mistt” and “Sierra Mist” sound nearly identical. Both operate in a consumer-facing context. For a company protecting a trademarked brand, a content creator with millions of followers using a phonetically identical name creates a plausible confusion risk, particularly as influencer brands increasingly sell merchandise, beverages, and consumer products.

Cierra Mistt’s reported counter was also legally grounded. She claims she had been using the name long before becoming a public figure, establishing prior personal use. In U.S. trademark law, prior use matters. A company cannot simply demand that a private individual abandon a name they used before the brand became prominent. The strength of that argument depends on the specific registration dates, use history, and commercial overlap, none of which are publicly available in this case.

What legal experts confirm is the one thing that cannot be disputed: PepsiCo’s trademark on “Sierra Mist” in its branded form remains active at the USPTO. The claim that Cierra Mistt registered the trademark herself and cornered PepsiCo legally is not supported by any public filing.

Why PepsiCo Really Retired Sierra Mist

The evidence is public and consistent. PepsiCo registered the Starry trademark in August 2022. The product launched in January 2023. Sierra Mist held 0.1 percent of the soda market in 2022, according to Beverage Digest data reported by CNN. Sprite held approximately 8 percent of the same market and was growing. PepsiCo’s own internal marketing acknowledged that lemon-lime demand had never been higher, and its brand had no part in that growth.

The decision was not reactive. It was strategic, planned at least six months before the public conversation about Cierra Mistt began. A company the size of PepsiCo does not retire a 24-year-old brand, design a new product, build a campaign targeting an entire generation, and file federal trademark paperwork because a TikTok creator’s username sounds similar to a soda. That narrative made for compelling content. It was not an accurate account of a corporate decision.

What the Dispute Reveals About Creator Trademark Rights

Set aside the viral mythology. The underlying question the Sierra Mist situation raises is real: can a corporation use trademark law to pressure individuals into abandoning personal names that predate their commercial prominence?

The answer is complicated. Trademark rights depend on use in commerce. A corporate mark that operates in beverages does not automatically extend to every human being whose name sounds similar, regardless of the company’s size or the brand’s recognizability. A cease and desist letter is not a lawsuit. It is a demand letter. Receiving one does not mean the sender has a winning legal position. Many cease and desist letters are sent on thin grounds.

Cierra Mistt’s situation, as described by her, reflects a pattern where large corporations use legal correspondence to pressure individuals who lack the resources to fight back. If her account is accurate, PepsiCo sent a demand with questionable legal merit, the creator pushed back, and the matter was dropped. That outcome, if real, is not unusual. It happens regularly in trademark disputes between asymmetric parties. The creator community’s reaction, celebrating the influencer as a corporate defeater, reflects genuine frustration with how trademark law can be weaponized regardless of merit.

PepsiCo’s Silence and What It Means

Corporate legal departments rarely comment on resolved private disputes. PepsiCo’s silence is neither an admission nor a denial. It is standard practice for a company that sees no upside in amplifying a story that portrays it as having pursued a questionable trademark claim against a content creator. Confirming the dispute escalated the narrative. Denying it amplified it further. Saying nothing let the story run its course.

That silence fed the viral version of events. In the absence of a corporate rebuttal, Cierra Mistt’s account filled the entire information space. The lesson for communications professionals is clear. Silence is a legitimate legal strategy. It is rarely a winning public relations strategy when the story is already circulating at scale.

Cases like this one echo broader tensions visible in disputes like the Lululemon v. Costco lawsuit over brand identity protection and the RAW Papers lawsuit, where corporate claims about brand authenticity came under legal scrutiny. The 23XI Racing v. NASCAR dispute offers a parallel in how power asymmetry shapes legal strategy when a smaller party pushes back against a dominant corporation.

What This Lawsuit Teaches Consumers

The Sierra Mist story is not really a lawsuit. It is a cease and desist dispute that went viral because it arrived at exactly the right moment: a beloved soda disappearing, a relatable creator claiming she forced a corporation to retreat, and a social media audience eager to believe that the underdog won.

The real lesson is structural. Trademark law gives large corporations significant tools to pressure smaller parties. A cease and desist letter costs a company relatively little to send. For the individual receiving it, the cost of ignoring or fighting it can be prohibitive. The bar for sending a cease and desist is much lower than the bar for winning a trademark infringement case in court.

For content creators and online personalities, the Sierra Mist story is a reminder to register trademarks early, document prior use thoroughly, and consult an attorney before responding to corporate legal correspondence. Rights exist on paper. Enforcing them requires documentation, not just confidence.

For consumers, the story is a reminder that viral narratives about corporate behavior are almost always incomplete. PepsiCo made a business decision. A creator made a claim. The claim spread because the timing was convenient. The actual trademark record supports neither the story that a creator forced a rebrand nor the story that PepsiCo had a strong legal position. The truth sits somewhere in a private resolution nobody has made public.
