Phhhoto Inc., a photography and social networking app, sued Meta Platforms, Inc. (formerly Facebook) alleging unlawful monopolization in violation of Section 2 of the Sherman Act. Phhhoto claimed that Meta engaged in a scheme to suppress its content on Instagram, including withdrawing access to key APIs, terminating integration projects, and adopting an algorithmic feed that deprioritized third-party content. Phhhoto filed suit in November 2021, more than four years after the alleged anticompetitive conduct began in 2016. The District Court for the Eastern District of New York dismissed the claim as time-barred, ruling that the four-year statute of limitations had expired and that equitable tolling did not apply because Phhhoto should have been aware of the injury earlier. Phhhoto appealed, arguing that Meta fraudulently concealed the anticompetitive nature of its conduct.
The Second Circuit reviewed the dismissal de novo, focusing on whether Phhhoto adequately alleged the three elements of fraudulent concealment: (1) the defendant concealed the cause of action, (2) the plaintiff remained ignorant until within four years of filing, and (3) the ignorance was not due to lack of diligence. First, the court held that Meta's 2016 press release, which listed neutral criteria for the algorithm but omitted any mention of suppressing competitors, was an affirmative act of concealment. The court rejected the argument that this was mere puffery, noting that the specificity of the release implied that competitive status was not a factor, thereby allaying suspicion. Second, the court clarified the legal standard for the second element, adopting the 'Hendrickson formulation' which requires the plaintiff to remain ignorant until within four years of the action's commencement, rather than within the limitations period. The court found that while Phhhoto knew it was injured in 2016, it did not have inquiry notice of probable anticompetitive wrongdoing until October 25, 2017. The court reasoned that a business decline alone does not trigger a duty to investigate antitrust violations, as procompetitive and anticompetitive conduct can produce similar effects. Finally, the court found that Phhhoto exercised reasonable diligence by investigating the cause of its decline and relying on Meta's public statements until the accidental discovery of the metrics discrepancy in 2017 provided the necessary comparator to suspect exclusionary conduct.
The judgment of the District Court is vacated, and the case is remanded for further proceedings. The decision allows Phhhoto's antitrust claim to proceed, as the statute of limitations is equitably tolled until October 25, 2017. This ruling clarifies that plaintiffs in antitrust cases involving algorithmic manipulation may toll the statute of limitations if the defendant's public statements or the nature of the scheme prevent the discovery of the anticompetitive intent, even if the plaintiff knew of the injury earlier. The state-law claims previously dismissed without prejudice are also vacated.
