The FDA has proposed amending its requirements regarding patents for brand-name drugs. If finalized, the proposed rule would (1) clarify that certain types of patents—including those claiming packaging, metabolites, or intermediaries—may not be listed by brand-name drug manufacturers; (2) revise the required patent declaration to help ensure that it includes only appropriate claims; and (3) limit to one a brand-name manufacturer's opportunity to secure a 30-month stay of FDA approval of an application for the marketing of a competing generic drug.
