Software company Openwave has filed complaints with the International Trade Commission and a Delaware district court, accusing Apple and Research in Motion of patent infringement, Reuters reports. In particular the electronics firms are charged with violating five patents used to connect smartphones and tablets to the Internet. "Before filing these complaints, we approached both of these companies numerous times in an attempt to negotiate a license of our technology with them and did not receive a substantive response," says Openwave CEO Ken Denman.
