A federal court has dismissed a lawsuit filed by Yangtze Memory Technologies, Inc. (YMTC) against Micron Technology, Inc. The case, Civil Action No. 2025-1795, was decided on August 13, 2026, by Judge Carl J. Nichols in the District Court for the District of Columbia. The court ruled that YMTC's claims of false advertising under the Lanham Act were not valid because the statements in question did not qualify as commercial speech.

This ruling impacts YMTC, a Chinese memory chip manufacturer, and its efforts to compete in the U.S. market. The decision highlights the challenges foreign companies face when entering the U.S. technology sector, especially amid concerns about national security and foreign influence.

Background

YMTC, headquartered in Wuhan, China, is a leading developer and manufacturer of advanced 3D NAND flash memory and related storage technologies. Its U.S. subsidiary, Yangtze Memory Technologies, Inc., manages its American operations. In 2022, YMTC was selected by Apple to supply advanced memory chips, which raised concerns among competitors.

Micron Technology, a U.S.-based competitor, allegedly initiated an astroturfing campaign to damage YMTC's reputation. Astroturfing is a deceptive practice where organizations create a false impression of grassroots support for a cause. Micron collaborated with DCI Group AZ, LLC, a public affairs firm, to launch a campaign that included a website called China Tech Threat, which purported to focus on policy but aimed to undermine YMTC.

In June 2025, YMTC filed a lawsuit against Micron and DCI, claiming they violated the Lanham Act by making false and misleading statements about the company. The suit alleged that these statements discouraged potential customers from purchasing YMTC's products, resulting in significant financial losses.

The Ruling

The court ruled in favor of Micron and DCI, granting their motions to dismiss the case. Judge Nichols stated that the publications challenged by YMTC did not constitute commercial speech, which is necessary for a claim under the Lanham Act. The opinion emphasized, "The publications in question also do not amount to 'speech proposing a commercial transaction.'" This distinction is crucial as the Lanham Act applies specifically to commercial speech that misrepresents goods or services.

In his ruling, Judge Nichols noted that the challenged statements were primarily focused on national security concerns rather than economic interests. He explained, "Both lacked the hallmarks of advertising. They instead contained several indicators of advocacy, including calling for government—not consumer—action." This determination was key in dismissing YMTC's claims.

Impact

The court's decision sets a precedent regarding the definition of commercial speech under the Lanham Act. It clarifies that not all statements made in a competitive context are actionable under this law. This ruling may discourage similar claims from companies that feel they have been harmed by public discourse that critiques their business practices or affiliations.

For YMTC, the dismissal of its claims means that it will not be able to seek damages for the alleged harm caused by Micron's statements. This outcome may hinder YMTC's efforts to establish a stronger foothold in the U.S. market, particularly as it competes against established companies like Micron.

What's Next

YMTC may consider appealing the ruling, but details about any potential appeal were not available in the court filing. The company will need to evaluate its options carefully, especially given the court's clear stance on the nature of the speech involved in this case.
