Question about Business Name

[np1986]

I've got a question about registered trade and business names.

I currently own a business called "The Moscow Bar and Grill". I have it registered as both a trade name as well as company name with my local registry.

Recently I had a fellow come to my business and claim he is going to sue me because he owns an establishment called "The Moscow Troika Bar". He claims I am infringing on his business name and goodwill. We are each located in different quadrants of the city (25 + minute drive) and offer similar food but in two different types of settings. His lawyer has written a letter claiming there is infringement on his business by way of "name confusion".

I have consulted two lawyers on this matter and have gotten two very different reactions. One told me there is considerable risk as the owner of the "The Moscow Troika Bar" can take me to court if he can prove he has loss of business due to my restaurant opening. The other has acknowledged there is risk but very small, and that his case is laughable.

Can anyone please shed some light on how likely this outcome would be? I am debating on whether to have my legal counsel respond or just ignore the letter completely.

I would appreciate any feedback.
Thanks.
