any patents and applications based on Licensor Improvements, at Licensor’s expense. Licensee will have the right to control filing, prosecution, and maintenance of patents and applications based on Licensee Improvements, at Licensee’s
expense. The party controlling the filing, prosecution, and maintenance of an invention is referred to herein as the “Prosecuting Party”, while the other party is referred to herein as the “Non-Prosecuting Party”.
The Non-Prosecuting Party shall have the right to participate, at its cost and expense, in the filing and prosecution activities of the Prosecuting Party. The Prosecuting Party will notify the Non-Prosecuting Party periodically of the status of any
pending cases included in the patents or patent applications licensed to the other party, including any office actions, notice of allowance, and required filings or payments concerning such patents and patent applications. The Non-Prosecuting Party
will have the opportunity to comment on any response to office actions or amendments to claims prior to their filing. The Non-Prosecuting Party will have the right to inspect the records kept by the Prosecuting Party and its patent counsel
pertaining to the patents and patent applications licensed to the Non-Prosecuting Party. The Non-Prosecuting Party will, at the Prosecuting Party’s request and expense, sign all instruments and documents, including powers of attorney, necessary
to effectuate the purpose of this Section 8.1 and provide any other reasonably necessary assistance requested by the Prosecuting Party. If the Prosecuting Party elects to abandon any application or patent licensed to the other party, the

 8.2 Enforcement. Each party will promptly notify the other party upon becoming aware of any known or suspected infringement of any patents licensed to the other party under this Agreement or the
license agreement referenced in Section 5.3. Such notice will include the identity of the party or parties known or suspected to have infringed the licensed patent and any available information that is relevant to such infringement. The party
who is the exclusive licensee of such licensed patent within the field of use subject to the infringement action (the “Enforcing Party”) will retain sole control over enforcement and defense of the patent against such third party
infringers. If the Enforcing Party files or defends any claim, suit, or action (a “Claim”) against any third party based on any licensed patent, the other party (the “Non-Enforcing Party”) will cooperate with the
Enforcing Party, at the Enforcing Party’s request, in enforcing or defending such Claim, including joining the Enforcing Party as a party to such suit or action to the extent necessary to establish standing. The Enforcing Party will be
responsible

the Receiving Party’s senior management and agrees to assist the Disclosing Party in remedying such unauthorized use or disclosure.
