Canon was accused of creating a monopoly.

Aunyx Corp, a Massachusetts manufacturer of toner for copiers, charged in a pair of legal actions that Canon Inc. of Japan and Canon U.S.A. tried to unlawfully monopolize the American market for a type of toner. Aunyx filed a complaint with the International Trade Commission as well as a $300-million suit in U.S. District Court in Boston. Aunyx charged that Canon dealers doing business with Aunyx have been threatened with retaliation by Canon, including threats to take away full-line dealer status.
