According to a report in the Washington Post BigPharma companies are abusing petition process to FDA to delay generics and hence keep drug prices artificially high:
"A procedure designed to alert the Food and Drug Administration to scientific and safety issues is getting a hard look from members of Congress, who say they are concerned that it may be getting subverted by the brand-name drug industry.
"Some at the FDA, as well as leaders in the generic drug industry, complain that "citizen petitions" -- requests for agency action that any individual, group or company can file -- are being misused by brand-name drugmakers to stave off generic competition.
"The simple act of filing a petition, they say, triggers another round of time-consuming and often redundant reviews of the generics by the FDA, which can take months or years. In the process, consumers continue to pay millions of dollars more for the brand-name drugs."
