. This followed a challenge to Ampyra, a treatment for multiple sclerosis. Now, Bass has filed another challenge, again related to a drug for MS.

The Boston Business Journal reported on 22 April 2015:

In a filing with the U.S. Patent and Trademark Office today [22 April 2015], the so-called Coalition for Affordable Drugs — which has already challenged patents held by Lexington-based Shire Pharmaceuticals (Nasdaq: SHPG) and Acorda Therapeutics (Nasdaq: ACOR) in New York and Chelsea, Massachusetts — challenged Biogen's patent No. 8,759,393 for Tecfidera by Biogen (Nasdaq: BIIB). That patent covers the twice-a-day dosage of the drug, which is currently Biogen’s top seller.
