Samsung has been sued in the United States over a patent on Wi-Fi technology. Salal Networks LLC has claimed that the Korean firm copied a network configuration method used in its smartphones, tablets, laptops, and TVs. The lawsuit seeks damages for patent infringement.

Samsung accused of copying patented Wi-Fi technology

Salal Networks LLC recently filed a patent lawsuit in the U.S. District Court for the Eastern District of Texas. The complaint mentions two defendants: Samsung Electronics and Samsung Electronics America. The case is tied to U.S. Patent No. 9,363,709, which covers technology for simplifying device connection to wireless networks.

Salal said setting up Wi-Fi and home networks was quite difficult in the early 2000s. The process required users to manually enter several values, such as the network name (SSID), security key, encryption settings, and IP address. The company developed a system to address this inconvenience.

The patented technology uses unique identification information to automate network configuration. It automatically creates the necessary settings after receiving a single identifier from the network. Salal claims Samsung’s products use a similar method through the IPv6 network system. The complaint points to the Stateless Address Autoconfiguration (SLAAC) feature.

When a user connects to a Wi-Fi router, SLAAC transmits the network prefix to the device. As a result, the device automatically generates its network address and other settings. The lawsuit argues that this process infringes on patents. As evidence, Salal presented Samsung’s publicly available open-source materials. The company checked the Galaxy S25 source code and found code related to IPv6 address generation and automatic network configuration.

However, Salal has not accused Samsung of intentionally infringing the patent. The company asks the court to confirm the infringement, award damages, and cover litigation costs. As of this writing, Samsung has not publicly commented on the lawsuit. It will be interesting to see how the Korean tech giant responds to the allegations in court.
