Charter asks Texas court to dismiss AT&T 'fiber-powered' lawsuit

Charter Communications filed a motion on Friday, October 23, asking a Texas district court to dismiss AT&T's false-advertising lawsuit over its use of the terms "fiber broadband network" and "fiber-powered." The motion, filed weeks after the complaint landed in late August, seeks dismissal "with prejudice" — a ruling that would permanently close the case and bar AT&T from refiling it.

The dispute matters beyond two operators. Its outcome could determine how extensively Charter and other cable operators running hybrid fiber/coax networks reference fiber in marketing, on websites and in customer communications across the US broadband market.

What does AT&T allege?

AT&T's complaint zeroes in on Charter's use of fiber terminology to describe its widely deployed HFC network. HFC architecture runs fiber to the node, then uses coaxial cable to connect homes and small businesses served off that node. AT&T argues Charter uses the language to affix a "fiber halo" to its broadband marketing, and that the practice causes "irreparable harm." AT&T has asked the court to declare that Charter engaged in unfair competition and to levy actual and "enhanced" financial damages.

Charter, for its part, reserves "100% fiber" for fiber-to-the-premises networks it is deploying in greenfield areas, including rural builds supported by government subsidies.

How does Charter answer?

Charter counters that AT&T failed to supply any facts showing consumers would read "fiber-powered" to mean exclusively fiber. "By failing to allege any facts that explain why reasonable consumers would conclude that 'fiber-powered' means 100% fiber, AT&T has not given the Court a basis to make that same inferential leap," Charter told the court. "AT&T's lawsuit is based on a theory of falsity that makes no sense and is belied by its own factual allegations."

Charter, which recently completed its merger with Cox Communications and markets under the Spectrum brand, argues a "reasonable consumer" would understand that its HFC network incorporates fiber but is not composed exclusively of fiber. It also contends the term would not plausibly be material to a purchasing decision.

The operator rejects the claim that it hides details about coax, pointing to diagrams on its website that illustrate the technical distinction between "fiber-powered" HFC and "100% fiber" FTTP. "A company bent on hiding its coaxial connection does not illustrate it, explain it in an FAQ, and disclose it on-screen in its advertising," Charter told the court.

Why a dictionary features in the filing?

Charter also leans on semantics. It argues "powered" is not a synonym for "100%" or "exclusively" but denotes a "component part of a product or service," and notes there is "no clear standard on what 'powered' means" in this context. The filing cites a Cambridge Dictionary usage example — "Most computers are now powered by Intel chips" — to argue the term is accurate because fiber plays a critical role in delivering broadband to its customers. Intel chips, Charter observed, are not a computer's sole energy source at all.

What is the regulatory backdrop?

The lawsuit follows a ruling by the National Advertising Division, the ad industry watchdog. In March, NAD said Charter/Spectrum "voluntarily modified disclosures in connection with its 'fiber-powered' claims," agreeing to discontinue references to HFC in ad disclosures tied to fiber-powered Internet services and to "clearly and conspicuously" disclose that such services are not delivered over fiber-to-the-home infrastructure. That concession apparently did not satisfy AT&T, which proceeded to court.

The fight also plays out against intensifying telco-cable broadband competition. AT&T aims to pass 60 million homes and businesses with fiber by 2030, while Charter builds FTTP in targeted areas alongside continued upgrades of its HFC footprint.

Fiber advertising language is not a new battleground. Comcast and Verizon clashed more than a decade ago over Verizon's "100% fiber optics" description of Fios, and Time Warner Cable — now part of Charter — had its own disputes with Verizon over the years.

What happens next?

The case now sits with the court, and more back-and-forth filings are possible before the judge determines next steps. Practitioners should watch the dismissal ruling first: a denial would push the dispute toward discovery on consumer perception, with implications for how every HFC-based cable operator in the US can talk about fiber.
