Roche Diagnostics, a Swiss company that keeps its U.S. headquarters in Indianapolis, has been sued for marking its Accu-Chek
blood glucose monitors and accessories with patents that are expired. Illinois resident David O’Neill has sued on behalf
of the U.S. government to recover damages of $500 per infraction.
Polymer Technology Systems Inc., a small Indianapolis-based maker of handheld blood monitors, has gone to court to fight
a competitor more than 100 times its size: Roche Diagnostics Corp.
