Background
Vasu Holdings LLC, a patent-licensing company, sued Samsung Electronics alleging that Galaxy smartphones infringed three of its patents covering wireless roaming technology. The centerpiece of the case was U.S. Patent No. 8,886,181, which covers methods and systems that allow mobile phones to maintain network connectivity as a device moves between carrier networks — a feature built into virtually every modern smartphone.
Samsung contested all three patents, arguing non-infringement and invalidity. After two years of litigation before Judge James Rodney Gilstrap in the Eastern District of Texas — one of the country’s busiest and most plaintiff-friendly patent venues — the case proceeded to a jury trial in late June 2026.
The Court’s Holding
The jury returned a split verdict on June 26, 2026. It found Samsung did infringe U.S. Patent No. 8,886,181, awarding Vasu Holdings $3 million in damages. On the two remaining patents (Nos. 10,368,281 and 10,419,996), the jury found no infringement. The jury also rejected Samsung’s invalidity defense as to the ‘181 patent, confirming the patent’s enforceability. Judge Gilstrap entered formal judgment on July 1, 2026.
The $3 million award reflects the royalty rate the jury determined Samsung owed for incorporating the ‘181 patent’s roaming functionality into its Galaxy handsets across the damages period.
Key Takeaways
- A federal jury awarded $3 million to a patent-licensing company for Samsung’s use of roaming technology in Galaxy smartphones, confirming that foundational wireless-connectivity patents remain enforceable targets for patent assertion entities (PAEs).
- Samsung prevailed on two of the three asserted patents, illustrating that courts and juries increasingly evaluate patents individually rather than accepting wholesale “portfolio” infringement theories.
- The ‘181 patent survived Samsung’s invalidity challenge, meaning it could be used in licensing demands against other Android manufacturers who implement similar roaming functionality.
- Eastern District of Texas remains a primary venue for patent plaintiffs: Judge Gilstrap’s court continues to attract a disproportionate share of national patent filings.
Why It Matters
Wireless roaming — maintaining a call or data connection as your phone shifts between cell towers and carrier networks — is so fundamental that virtually every smartphone on the market implements it. When a patent covering that core function survives validity challenges and attracts a damages award, other manufacturers using similar technology take notice. A $3 million verdict against Samsung is relatively modest given the scale of Galaxy phone sales, but the ‘181 patent’s survival opens the door to licensing demands against the broader Android ecosystem.
For practitioners, the split verdict is a reminder to carefully prioritize which patents go to trial. Presenting a jury with three patents — winning on one and losing on two — can dilute the damages narrative and signal to the market that the portfolio has weaknesses. PAEs should consider focusing their jury presentations on the strongest claims rather than maximizing the number of asserted patents.
