I won a domain through back ordering service. Created a different website and currently using it as a PBN. About a week ago the lawyer representing the previous owner contacted me. Below is the email Our client is the owner of the French trademark ........, registered since 200x under number xxxxx and has acquired common law rights in the trademark ... from its longstanding use of the trademark. Our client has recently been informed of your registration of the domain name ...... and believes your registration and use of same infringes on its trademark rights. We, therefore, demand that you transfer said domain name to our client forthwith. I have over 100 domains in my PBN, this is the 1st time I have been contacted. What are my options Thanks for your help. Advice from people who have been in this situation would be appreciated.
