The US Supreme Court has rejected an appeal filed by GlaxoSmithKline against Apotex over the latter’s development of a generic version of the blockbuster antidepressant Paxil. Apotex and GlaxoSmithKline’s patent dispute over Paxil dates back to 1998 when SmithKline Beecham sued Apotex for infringing on the patent covering paroxetine.That case went to trial in 2003, with a US District Judge ruling that SmithKline Beecham’s patent was valid. That ruling was later overturned by the Federal Circuit Court. Paxil sales reached $1.1 billion last year.
