In an unusual move, an advocacy group asked federal authorities to reject a request by Gilead Sciences (GILD) for a three-year patent extension on an HIV drug because the company allegedly lied about important information in its application.
The group argued in an emergency petition with the U.S. Patent and Trade Office that Gilead concealed a decision to delay development of the drug, called TAF, in order to thwart generic competition and “game” the patent system. In the process, the company reaped billions of dollars in additional sales while knowingly marketing an older drug that the company believed was not as safe.
