It depends. In an application based on “use” of the mark in commerce, assuming there are no initial refusals or other obstacles, you can expect a registration in 7 – 12 months. An application based on “intent to use” is similar in length of time to a “use” application. It will also require a showing of the mark in use before the application can proceed. From the point that you can show the mark in use, you can expect a registration in 2 months.
