  Summary: The court rejected the defendants' application to stay the proceedings and ordered the appointment of a court-appointed expert under Rule 185 RoP to resolve disputed technical questions about the accused embodiment. The court found the patent in its granted form likely invalid but potentially valid in the form of auxiliary request 10B, and deferred any substantive ruling pending the expert's findings.
