definiens: means any potentially patentable or patented invention conceived by or on behalf of one orboth Parties and/or its Affiliates, employees, agents or independent contractors in the course of conducting its or their activitiesunder an Approved Research Plan, in each case directed Specifically to [COMPANY] Technology related to a ) ReCode, b ) EuCode, orc ) Linker Technology ( [COMPANY] Technology directed Specifically to a ), b ), and c ) collectively referred to as ), and shall include, without limitation, Joint Inventions, but shall specifically exclude Compound Inventions thatare not directed Specifically to Non - Natural Amino Acid Technology . For purposes of this definition : i ) and mean the design, creation, modification and/or generation of Compounds through the incorporation, substitution or addition of oneor more non - naturally encoded amino acids ( i.e., amino acids other than the 20 naturally - encoded amino acids ) using orthogonaltRNA / aminoacyl - tRNA pairs, including non - naturally encoded amino acids providing one or more points of site - specific attachmentfor a drug, into the amino acid sequence of the polypeptide comprising such Compounds ; and ii ) meansany technology in which a functional group, such as, but not limited to, a chemical, carbohydrate or polypeptide, is used to link orattach, by a covalent bond or otherwise, one or more drugs Specifically to a polypeptide synthesized using ReCode or EuCode toform a polypeptide drug conjugate . As used herein, shall mean that the invention is a small molecule, protein, carbohydrate, nucleic acid, cell, vector, etc ., that is specially adapted for use with a non - natural amino acid, and not moregenerally with natural amino acids or other substrates such as small molecule ligands, proteins, carbohydrates or nucleic acids
