A nonprofit organization that provides services to pregnant women in Canada and the United States is suing a Connecticut-based company for trademark infringement for using a phrase similar to its patented slogan “We Love Them Both!”

Birthright, which is based in Toronto, has more than 400 emergency pregnancy counseling centers operating under its charter throughout the United States and Canada and other jurisdictions, according to the lawsuit filed in U.S. District Court in Bridgeport on Friday. Of those centers, 10 operate in Connecticut. Birthright centers have operated in the U.S. continuously since 1968 and has, since November 1995, used the phrase “We Love Them Both!” in its promotional material.
