Short Summary
The PTAB denied Microsoft's request to institute Inter Partes Review (IPR) against Proxense's patent 8,886,954. The denial was based on a procedural condition that required prior non-institution in a related proceeding.
Detailed Summary
In this Institution Decision, the Patent Trial and Appeal Board denied Microsoft Corporation’s petition for Inter Partes Review (IPR) against Proxense, LLC regarding U.S. Patent No. 8,886,954. The petitioner had filed a conditional motion to join the proceeding, which was contingent upon the Board having previously denied institution in IPR2024-00846. Because the Board had already instituted review in that related proceeding, the condition for joinder failed, resulting in the denial of the petition under 35 U.S.C. § 314(a).
