definiens: shall mean, with respect to a Target, ( a ) a compound comprising ( i ) a moiety that binds to that particular Target ( ), ( ii ) a linker ( ), and ( iii ) a moiety that binds to the E3 ligase cereblon or another E3 ligase, in possession of or Controlled by C4 T or [COMPANY] ( ), generated under a Research Plan, whose primary mechanism of action is, by design, degradation of such Target, or ( b ) any salt, polymorph, metabolite, Prodrug, isomer or stereoisomer of the compound in clause ( a ) . The Target Binding Moiety can be a [COMPANY] Compound, a compound identified by C4 T that binds to Target, or compound identified in literature and agreed -upon by the Parties as part of the Research Plan, or any derivative thereof identified by C4 T or [COMPANY] during the execution of the Research Plan . For clarity, Target Binding Moiety and Degronimid exclude a separate Linker, a separate E3 Ligase Binding Moiety and a separate Linker bound to an E3 Ligase Binding Moiety . A listing of the [COMPANY] Patent Rights on the E3 Ligase Binding Moiety as of the Restatement Date is attached as Appendix 1.39
