AI are already generating antibody treatments. Companies provide AI with the disease/issue and antibodies that kinda work, then have the AI generate antibodies to fix the disease/issue. The best antibodies are then made in a lab and tested in vitro. However, as somone else noted, antibodies/medications are patented, which is different than copyright. Patents can be done on the process of making the antibody so you patrent the final process of making the antibody, not the AI work to come up with which antibody to make.
