Narrative Opinion Summary
In this case, the plaintiffs moved to preclude the defendant, Open Biosystems, Inc., from using fact and expert witnesses at a forthcoming Claim Construction Hearing, alleging a violation of Patent Rule 4-2(b) due to the defendant's failure to disclose witnesses with its preliminary claim constructions. The plaintiffs contended that this omission provided the defendant with an unfair advantage. However, the defendant argued that it complied with the necessary rules, providing all required extrinsic evidence and following the procedural timeline which allows for witness disclosure at a later stage under Patent Rule 4-3(b). The court sided with the defendant, supporting its interpretation of the rules, which permit the gradual identification of witnesses in response to evolving claim construction discussions. Consequently, the court denied the plaintiffs' motion entirely, including the request for attorneys' fees, citing a lack of prejudice and adherence to the court's Case Management Order. The ruling allows the defendant to present its witness, Dr. Tal Kafri, at the scheduled hearing, ensuring both parties have an opportunity for comprehensive claim construction adjudication.
