OK, back in 2005 I created a website, which is adult orientated, I don't know if this changes things but anyway. Today I received a letter stating that I am trading under their name. They are not happy, blablabla and that they want the issue resolved. They are basically saying I'm using their company name... "<NAME> is a registered trade mark which has been in use since 1986" "I have contacted company house and have been assured that you are not a registered company." "I have been advised by my legal team to inform you that you use of my company name contradicts the identity of the goods and services offered by our company as also the influence on the reputation of our company." The site I run is a personal website, it is not a company nor am I trading. No where on the site do I claim to be a company, or request any funds or payments. Its an adult directory with the domain name .net is the same as their .co.uk domain name. They do not run an adult site. The company is registered at Company House. Name is TMed with an ! at the end, I think its just for within the logo? Class 37: Washing of linen; ironing; weed killing; window cleaning; cleaning of domestic and commercial premises; cleaning of carpets, upholstery, domestic utensils, furniture and of curtains; painting and decorating; all included in Class 37. Class 42: Housekeeping; gardening; baby sitting; mothers' help and nannying services; catering and cooking services; waitressing, maid and butler services; all included in Class 42. Disclaimer: Registration of this mark shall give no right to the exclusive use of the words "<NAME>!". Now, am I safe? Any advice? Thanks. P.S Obviously <NAME> would be the company name and domain names.
