Do I have a legal basis for contesting the use of the singular version of my business name? I believe that it would cause confusion amongst my clients. I have a pet care business. I registered the plural version of SOMENAMEwalks.com and business name in 2008. I built my business up for 6 years and it's well established. Someone has registered the domain MYNAMEwalk.com, for the same service, targeting the the same city. They have a website that is currently under construction. If there is merit to my case, where should I start?Oops, that should read SOMENAMEwalks.com and SOMENAMEwalk.com. Also should mention that this is a localized business. My client base is limited to roughly a 5 mile radius from my home.
