Therefore, for good and valuable consideration, the receipt and sufficiency of which Assignor acknowledges, Assignor hereby irrevocably sells, assigns, transfers, and conveys to Assignee, and Assignee hereby accepts, all of the full extent of Assignor’s right, title, and interest in and to any and all of the following (collectively, the “Patent Rights”):

 

	
 
	
•
	
U.S. Patent No. [***]  (the “Patents”);

	
 
	
•
	
All substitutions, continuations, continuations-in-part, divisions and renewals relating to the Patents, solely to the extent filed in the United States; 

	
 
	
•
	
All patents-of-addition, reissues, reexaminations, extensions, or registrations of any and all of the Patents;

	
 
	
•
	
All causes of action and remedies related to the Patents in the United States (including the right to sue for past, present or future infringement, provisional rights under 35 U.S.C. § 154, misappropriation or violation of rights related to the Patents, and all rights to pursue damages, injunctive relief and other remedies for past and future infringement of the Patents in the United States);

	
 
	
•
	
All rights to collect royalties and other payments under or on account of any of the Patents; and
