In Copyright vs. Trademark - updated on 12/20/2010
I started a national link directory in 1995 of the United States. I created directories for business website to add their links. I just got an email about infringement. Can you trademark a phrase that is common like Michigan Manufactures Directory. My Directory is of business links and its copyright is in 1998. their directory is of business profiles and product information, and his fist use is 1999 and the trademark in March 10, 2009. now he wants me to rename my directories. should I?
