Hi Achal – it is amazing these days with Google to be able to search to find other people using similar names. There are a few things to think about here – including ‘how’ unique the name is vs generic and also prior use of it, and in what category of similarity e.g. is it the same name in the same industry in the same town. This is not always the case, but often if there is a prior use of the name then there is an argument that they were there first. This can get nullified if it is a generic name.
Beyond all of this – what I would say is get some good legal guidance, and hopefully we can get a couple lawyers to give you some guidance. Andy
