definiens: shall meanCny applications that relate to molecular ~ arrays, including without limitation the scree ~ f arrays, excluding applications that relate to ( i ) molecular arrays of Biomolecules or affinity ligands that are intended for use with applications in the separation, concentration, or analysis of Biomolecules, Natural Products, and Derivatives, ( ii ) molecular arrays of monomeric Biomolecules or monomeric Derivatives of Biomolecules that are intended for use with applications in the synthesis of polymeric Biomolecules, and ( iii ) kits intended for use in the production of molecular arrays under clauses ( i ) and ( ii ) . For the purposes of this definition, the term means and includes any of the following ; ( a ) an ordered array - a collection of molecules that is logically arranged based on physical characteristics in such a manner that the collection of molecules possesses a constant physical element and a variable physical element ; ( b ) a combinatorial array - a collection of molecules that is produced by the combinatorial assembly of molecular building blocks ; ( c ) a directed array - a collection of molecules that are produced by modification of one or more structural components of one or more target molecules according to a general scheme ; ( d ) a random array - a collection of molecules produced by simultaneous or serial chemical and/or physical operations on an initial set of molecules ; and ( e ) a natural products array - a collection of Natural Products or a collection of mixtures or extracts that contain Natural produc9 1.10 . shall mean all molecules ( other than Biomolecules ) that are the naturally occurring products of biosynthesis in living cells or are produced by isolated cellular components outside of living cells, whether by natural means or by organic synthesis in solution or using solid phase technologies . This definition is intended to include sub­cellular components and viral particles . Examples of Natural Products are vitamins, steroid hormones, and various cofactors
