Ericsson sues Disney in Brazil over multimedia patents

The Swedish telecom company has launched a patent infringement action in Rio de Janeiro, alleging that Disney’s streaming services use its patented video codec technology without a license.

Ericsson has filed a patent infringement lawsuit against The Walt Disney Company in Brazil, opening another front in the entertainment giant’s growing international patent disputes over multimedia technology.

The case was filed in the 6th Business Court of the Capital District of Rio de Janeiro under case number 3208109-52.2026.8.19.0001, according to specialist publication ip fray, which reported the action on October 15, 2026.

Ericsson alleges that Disney’s streaming services have been using its patented video codec technology without a license agreement. The company said it had negotiated with Disney for years before deciding to pursue litigation.

“Ericsson has been at the forefront of video codec development for decades and has a strong patent portfolio,” the company told ip fray. It added that it remained hopeful the parties could reach a commercial solution to resolve the pending disputes.

The report also indicates that Ericsson has filed a related patent action in another jurisdiction, although that jurisdiction has not been identified in the available reporting.

Patent details remain unconfirmed

The available report does not identify the individual Brazilian patents asserted by Ericsson or specify the technical features Disney is alleged to have infringed.

Although Ericsson’s statement identifies video codec technology as the subject of the dispute, further details are needed to establish whether the allegations concern particular video compression standards, encoding or decoding processes, or other multimedia functionality.

The specific claims, requested remedies, and technical scope of the alleged infringement should therefore be treated as unconfirmed until the complaint or additional court records become available. The allegations have not been adjudicated in this action, and no finding of infringement has been reported.

Brazil’s role in multimedia patent enforcement

The filing highlights Brazil’s importance as a venue for international patent enforcement involving telecommunications and digital media.

Ericsson’s action comes amid a wider series of disputes over video coding and streaming technology. Disney is separately defending Brazilian patent litigation brought by InterDigital and IBEX, involving their respective multimedia patent portfolios.

InterDigital has pursued claims concerning video coding technology in Brazil, while IBEX has brought a separate action concerning a patent directed to video encoding. Those proceedings involve different patent holders and allegations and do not establish the merits of Ericsson’s claims.

For patent owners, litigation can become a means of advancing licensing negotiations when commercial discussions fail to produce an agreement. Pursuing claims in multiple jurisdictions may also increase the complexity of resolving disputes involving technologies distributed and used internationally.

Ericsson’s filing follows a period of growth in its intellectual property licensing business. In its third-quarter 2026 financial reporting, the company disclosed a 25% increase in intellectual property rights licensing revenue and highlighted opportunities to improve the terms and value of new agreements and renewals.

The company’s July 2026 settlement of global patent litigation with Chinese smartphone manufacturer Transsion provides a further example of its efforts to resolve licensing disputes through commercial agreements.

Implications for streaming services

The case adds to the patent licensing challenges facing Disney’s streaming business, but its significance will depend on the patents asserted, the technical allegations and the remedies Ericsson seeks.

Video compression and codec technologies are central to the efficient delivery of digital video. Disputes over their use can involve complex questions concerning patent scope, infringement, and licensing obligations, particularly where multiple patent portfolios cover related aspects of multimedia technology.

For Ericsson, the Brazilian action represents another attempt to resolve an alleged unauthorized use of its intellectual property through the courts after years of negotiations.

Whether the proceedings lead to a licensing agreement, damages award, or other relief remains to be seen. Until the complaint is available for review, the precise technical and legal issues at the heart of the dispute remain unclear.
