WHEREAS, on December 4, 2023, Lionra filed an Amended Complaint (Dkt. No. 42)

dropping the ’441 patent;

WHEREAS, Cisco has not yet filed a petition for Inter Partes Review (IPR) of the ’441 

Patent;

NOW, THEREFORE, in consideration thereof and of the mutual agreements, provisions 

and covenants contained herein, and for other good and valuable consideration, the receipt and 

sufficiency whereof are hereby acknowledged, the Parties HEREBY STIPULATE AND AGREE 

AS FOLLOWS:

1. Lionra, for and on behalf of itself, as well as any of its predecessors, successors, 

assigns, directors, officers, employees, and agents, hereby releases and unconditionally and 

irrevocably covenants to refrain from making any claim(s) or demand(s) against Cisco or any of 

its parents, subsidiaries, divisions, and affiliates, as well as any of their predecessors, successors, 

assigns, directors, officers, employees, agents, and distributors (collectively, “the Cisco

Covenanted Parties”) based on any possible cause of action arising under the patent laws of the 

United States, relating to any claim of the ’441 Patent with respect to any product made, used, 

sold, offered for sale, or imported by the Cisco Covenanted Parties, regardless of whether the 

products are made, used, offered for sale, or imported before, on, or after the date of this covenant. 

The covenant for the ’441 Patent extends through the life of the ’441 Patent plus the resulting 6-

year statutory damages period set forth in 35 U.S.C. § 286. For avoidance of doubt, this covenant 

does not apply to the ’518 Patent. 

2. Cisco will not file an IPR against the ’441 Patent;

3. This Stipulation is the sole and entire agreement between Cisco and Lionra made

in connection with, or in contemplation of, an IPR against the ’441 Patent.
