Note 10. Subsequent Events	On April 4, 2017, the U.S. Patent & Trademark Office (the “PTO”) issued to the Company U.S. Patent No. 9,610,430 related to its device and method for spraying autologous skin cells. On or about April 11, 2017, the Company received from Avita Medical Limited (“Avita”) a paper copy of what was labeled a Petition for Inter Partes Review purporting to challenge the validity of the claims in U.S. Patent No. 9,610,430 (the “Petition”) before the Patent Trial and Appeal Board (“PTAB”), which is an administrative proceeding of the PTO (the “Proceeding”). The Company does not agree with the assertions set forth in the Petition and intends to defend its intellectual property. In the event the Proceeding progresses, the PTAB may find (i) that the Petition is insufficient to establish that any such claims are unpatentable and accordingly confirm all of the claims in the Company’s U.S. Patent No. 9,610,430 or (ii) one or more claims of U.S. Patent No. 9,610,430 to be unpatentable and cancel any such claims and confirm the balance of such claims.
