IPR Estoppel Warrants Exclusion of Patents and Printed Publications Except to Establish Dates of Public Use or Sale of Systems​

The court granted plaintiff's motion in limine to preclude invalidity arguments based on certain patents and printed publications due to IPR estoppel, but denied the motion as to prior art systems. "While [defendant] will be permitted to present its defense of invalidity based on [two prior art] systems, [defendant] will be limited to using any documents that qualify as patents or printed publications solely for the purpose of establishing the date on which the [two prior art] systems were in public use or on sale. [The motion is] denied as to [plaintiff's] argument that [defendant] is estopped from asserting the [two prior art] systems as prior art."
