If you have just invented a certain product, or have just come up with a great idea, you must get a patent and register to ensure you get a trademark registration.
Trademark registration is important so that no individual or company can steal your ideas. You have to take the proper steps to ensure your name is tied to the product, service, or invention, and to ensure it is properly registered, so that no one else can use the idea that you have come up with, without your permission, or without first paying you some type of royalty for the use of the idea.
When someone comes up with a million dollar idea, he should consider turning to a professional to get the trademark registration completed; you can call an attorney. Your lawyer is not only going to know the proper steps to take, but they are also going to do it in a timely fashion to ensure no one else can jump on board and take the credit for your creation.
Although you can do everything online these days, trademark and patent registration is a big thing especially if it is a big idea, or something ground breaking, you should definitely opt to talk to a professional and have an attorney work on the trademark registration on your behalf.
