Takeda files US patent case

Takeda sues Dr Reddy's over patent infringements related to Dexilant drug

Takeda Pharmaceutical has filed a patent infringement suit against India's Dr Reddy's Laboratories in a New York court. The suit relates to efforts from Dr Reddy's to manufacture a generic version of Takeda's acid reflux treatment drug Dexilant (dexlansoprazole).

Takeda alleges that the Indian generic-drug maker and its US subsidiary have infringed US patent numbers through the submission of an abbreviated new drug application seeking approval to market generic versions of Dexilent.

The drug has an annual market size of more than $300m in the US market, according to IMS Health figures.

Dr Reddy's was unavailable for comment at the time of writing.
