Page 1 of 1
CoolSavings.com Inc. Monday filed three more lawsuits in a Chicago federal court, charging companies with violating a patent it was granted for its interactive marketing method.
The news comes after the company filed suits against three other companies, beginning with Emaginet Inc. on Oct. 19.
In the latest lawsuits, CoolSavings alleges the other sites offer consumer and advertiser services that infringe on its patent for distributing printed and electronic coupons over the Internet.
"These separate lawsuits are part of our effort to vigorously enforce CoolSavings patent rights against companies who infringe on these rights," said Steven M. Golden, CoolSavings' chairman and chief executive officer.
The companies named in the suits could not be reached for comment.
