Hey Meredith,

Am in process of registering a LLC in Maryland. The name of the business is unique in the Maryland state but the exact business name is registered in California.

So my question is can I register it? Will there any complication?

    Hey Tom,

    If there is no trademark registered for the name than you can register it. You can search for trademarks registered in Maryland using this search tool.
