Ranjit Bedi, a Californian, has filed a lawsuit against Hewlett-Packard and Staples in a U.S. District Court in Boston, accusing the two companies of colluding to prevent the sale of third-party ink cartridges in Staples stores. Bedi is accusing HP of paying Staples over $100 million to get it to stop selling lower-priced ink refills, but none of the news sources we found supply any evidence to support that figure, so we hope Bedi has more than just a gut feeling about this.
