Ed Silverman, STAT; Allergan is dealt another setback as patent board shoots down Mohawk patent deal

"In a closely watched case, a U.S. patent appeals board ruled that a Native American tribe cannot claim sovereign immunity in order to avoid a certain type of patent challenge. The decision is a blow to Allergan (AGN), which last fall transferred patent rights to one of its biggest-selling medicines to the St. Regis Mohawk Tribe in hopes of thwarting generic competition.

Procedurally, Allergan sought to avoid inter partes reviews, a type of patent challenge that has vexed drug makers since going into effect six years ago, because these are easier and faster to file than patent lawsuits. At the time it transferred patent rights to its Restasis eye treatment, which last year generated more than $1.4 billion in sales, Allergan was facing a conventional patent challenge in a federal court."
