Registering a new company? (easy question)?

[James R.]

I want to reserve my company name, (it is available), and I am going to begin creating the prototype of my product soon here but wont establish the business for about 3-4 months from now, so I might as well save on the Ca franchise tax and all the other paperwork and fees til the time comes for me to kick off business and order inventory. Can I only secure the fictitious name for now, and not worry about anything else? Or must I fill other forms out and register in other ways?

Thank you!
