Following its second suit against Roku last month, Flexiworld Technologies, Inc. has now filed another suit against the same defendant (6:21-cv-00767) in the Western District of Texas, adding another four media streaming/casting patents to litigation and bringing the total number of patents-in-suit to 13 between the two parties. Meanwhile, Amazon has won a convenience transfer of Flexiworld’s case against it to the Western District of Washington, leaving for the new court to decide its two motions challenging Flexiworld’s standing to sue in the first place, based on Flexiworld’s prior assignment agreement with Samsung.
