Yes, just like any company with a virtual office. But the Supreme Court in TC Heartland last year limited where patent suits can be filed. Now, a _defendant_ needs a physical presence in east Texas to be sued there. Only big box retailers with stores in east Texas towns, or companies with headquarters / offices / storefronts in Dallas suburbs like Frisco or Plano, can be sued there. The virtual office for the patent owner no longer had any effect on the suit being proper in east Texas.
