that violate Heelys patent on a “multi-wheel heeling apparatus.”


Heelys said in the complaint that it had previously
sent letters to two of Wal-Mart’s buyers to inform them of the patents
held by HLYS. Finally, HLYS alleges that “unless enjoined by the
court…Wal-Mart will continue to infringe” on Heelys’ patent. 
The company, based in

blocking Wal-Mart from selling products found to violate the patent and cash
compensation.
