GSK settles antidepressant patent dispute

GlaxoSmithKline has said it is to pay a settlement of $35 million to Watson Pharmaceuticals, ending patent litigation related to the antidepressant Wellbutrin XL.

<p>The original litigation related to Andrx Corporation which Watson acquired for $1.9 billion in 2006. <br /><br />In 2005, Andrx Corporation filed a patent infringement lawsuit in a US District Court against GlaxoSmithKline alleging that its Wellbutrin XL extended-release tablets in 150mg infringed Andrx&#0039;s patent. <br /><br />Andrx has granted GlaxoSmithKline a royalty-bearing license to the patent. Other terms of the settlement and license were not disclosed.</p>
