New drugs for human use; clarification of requirements for patent holder notification--FDA. Proposed rule

The Food and Drug Administration (FDA) is proposing to amend its regulations on notice of certification of invalidity or noninfringement of a patent to provide additional methods for new drug and abbreviated new drug applicants to provide notice to patent owners and new drug application (NDA) holders, without removing the existing means. These proposed amendments reflect current business practices and are intended to ensure that notice is provided to patent owners and NDA holders in a timely manner. FDA is also proposing to require certain applicants to submit to FDA a copy of the notice of certification.
