Red Rock Analytics, LLC sued Apple and Qualcomm in April 2021 in the Western District of Texas. In August of that year, the defendants filed a motion to transfer venue for convenience to the Northern District of California. Claim construction briefing has gone into the court, but in June 2022 District Judge Alan D. Albright stayed proceedings pending resolution of the motion to transfer, the Federal Circuit having warned that the merits of a case should not be touched until threshold matters, like a convenience transfer request, are decided. On the third anniversary of its filing, the defendants’ transfer motion has been briefed through sur-sur-reply, with four subsequent supplements having been filed, the fourth in March 2024. Since then, the docket has been quiet.
