In a lawsuit filed in the US District Court for the Eastern District of Texas, Soverain accused Apple of infringing patents relating to data extraction and network management.
The patents originated from Open Market, a tech firm that developed technology in the early days of the internet.
Soverain has steamrolled through a series of lawsuits, beginning in 2004 when it sued Amazon and Gap for infringement of virtual shopping cart patents, also obtained from Open Market.
Both companies settled, with Amazon paying $40 million to Soverain.
But Soverain seemingly took its lawsuits one step too far by suing Newegg, which refused to settle, instead challenging Soverain and winning its case at the US Court of Appeals for the Federal Circuit.
In 2015, Soverain had the last of its shopping cart patents invalidated.
The new lawsuit covers a broad range of Apple products, including the iPhone, Apple Watch and Mac.
In its complaint, Soverain claims that Apple’s infringement has caused it to suffer “monetary damages” and it seeks “recovery in an amount adequate to compensate for Apple’s infringement”.
