Network-1 Technologies Inc. Takes Legal Action Against Samsung Over eSIM Technology

In a significant development within the tech industry, Network-1 Technologies Inc., a U.S.-based company specializing in information technology and communication equipment, has initiated a patent lawsuit against Samsung Electronics Co., LTD and Samsung Electronics America, Inc. This legal action, announced on June 30, 2025, marks a pivotal moment for Network-1 as it seeks to protect its intellectual property rights in the rapidly evolving field of eSIM and 5G technologies.

Network-1, listed on the NYSE American, is renowned for its CYBERWALLPLUS family of security software products, which provide comprehensive protection for computer networks. However, the company’s focus has recently expanded into the realm of mobile technology, particularly through its acquisition of a robust M2M/IoT patent portfolio in December 2017. This portfolio, which includes 41 issued U.S. patents and 15 issued non-U.S. patents, covers critical aspects of eSIM technology and 5G network authentication.

The lawsuit, filed in the United States District Court for the Eastern District of Texas, alleges that Samsung infringes on six specific U.S. patents. These patents are integral to the authentication and usage of eSIM technology in IoT, Machine-to-Machine, and mobile devices, as well as 5G network authentication technologies. The patents in question are U.S. Patent No. 11,233,780, U.S. Patent No. 11,916,893, U.S. Patent No. 12,207,094, U.S. Patent No. 12,166,869, U.S. Patent No. 11,606,204, and U.S. Patent No. 11,973,864.

Samsung’s Accused Products, including its Galaxy smartphones, watches, and tablets, are said to operate in accordance with certain GSMA and ETSI industry standards, which allegedly infringe upon Network-1’s patents. The significance of this lawsuit is underscored by the growing importance of eSIM technology in the mobile industry. According to the Trusted Connectivity Alliance, eSIM device shipments exceeded 500 million units in 2024, with eSIM profile downloads increasing by 56%.

Network-1’s legal action against Samsung is not just about protecting its patents but also about asserting its position in the competitive landscape of mobile technology. The M2M/IoT Patent Portfolio, with patent terms extending until 2033-2034, remains available for licensing to companies utilizing these technologies. This move highlights Network-1’s strategy to leverage its intellectual property to foster innovation and collaboration within the industry.

As the legal proceedings unfold, the tech community will be closely watching the outcome of this case. The implications of this lawsuit could have far-reaching effects on the development and deployment of eSIM and 5G technologies, potentially reshaping the competitive dynamics in the mobile technology sector. For Network-1, this legal battle represents a critical step in safeguarding its innovations and ensuring its continued growth in the information technology landscape.
