Short Summary
Petitioner Tessell, Inc. filed an authorized response opposing Nutanix, Inc.’s request to reverse the PTAB’s institution of IPR2025-00298. The brief argues no unfair dealing, cites settled expectations for early‑filed patents, and asserts that discretionary denial under §325(d) is improper.
Detailed Summary
In an authorized response to the Director’s review request, Tessell, Inc. defends the PTAB’s decision to institute IPR2025-00298 against Nutanix, Inc.’s ’818 patent covering database provisioning in a hyperconverged infrastructure. The petitioner argues that the alleged unfair dealing claim is baseless because the inventors departed Nutanix before the continuation was filed and the patent’s claims were broadened to remove the hyperconverged limitation. It further emphasizes that the patent’s recent issuance creates settled expectations favoring institution, and contends that discretionary denial under 35 U.S.C. §325(d) is unwarranted given the examiner’s material error and the extensive prior‑art references.
