Anthony Kennedy,
Eli Lilly and Company v. Medtronic Inc…
“ Congress did not act in an irrational manner when it drew a distinction between drugs and medical devices. True, like medical devices, some drugs have a very high cost. See ante, at 673, n. 5. Testing a patented medical device, however, often will have greater effects on the patent holder's rights than comparable testing of a patented drug. As petitioner has asserted, manufacturers may test generic versions of patented drugs, but not devices, under abbreviated procedures. ”
