Half the Molecule, Half the Royalty

Contract Persistence in an Immunotoxin Licence Ledger, 1981–2006

A research poster from the School of Settled Matters reads eight versions of one immunotoxin consortium's licence agreement against 104 quarterly cost sheets, 1981–2006. The toxin chain's share of unit production cost fell from 47% to 6% while its half of the royalty was retyped verbatim in seven of the eight versions, and 31 of 44 substantive edits fell instead on the definition of "Conjugate", through which the parties moved new formats in and out of the royalty base.
