Short Answer: It depends.
Long Answer: Filing for a patent application is NOT a simple one-step process, which is why you need an experienced patent attorney to help you along the way. For example, your idea or invention can be very simple (i.e. paper clip) or very complex (i.e. telecommunication/network system) which affects the costs. In addition, your invention can be either a candidate for a Design Patent Application or Utility Patent Application(or both), both having much different costs associated with them. In addition, if you are filing for a Utility Patent Application, you will need to decide if you want to file for a Provisional or Non-Provisional Patent Application, which again each has its own costs associated with them.
