LG Chem has won the 2nd trial of a patent dispute over the use of DPP-4 inhibitor diabetes drug Zemiglo (gemigliptin). The company was able to reverse its first trial loss and won the second trial, enabling it to prevent patent challengers from launching their generic versions early.

The pharmaceutical industry's attention has now turned to another second trial. LG Chem is battling generic companies in patent court over the invalidity of its use patent. If LG Chem wins, it will make it even harder for generics to launch their generic versions of Zemiglo early.
