If the complexities of legalities seems simple, you may want to consider becoming a patent agent or patent attorney. If you are a do-it-yourselfer (DIY), you may want to get David Pressman's book "Patent it Yourself" or David Hitchcock's book "Patent Searching Made Easy". If you are like the rest of us, this process does not seem simple. Sure it may cost some money to engage someone to guide you through this process, so you need to carefully consider your innovation in context of (1) is it patentable? and (2) is it a viable business opportunity? It may, however, be in your best interest to learn as much as you can about the system and then hire a competent patent attorney to get the job done. Just think what it would cost to great idea, poorly patented, which may ultimately cost you "like a bigillion dollars in lost royalties or something like that."
Ignorance is not bliss. Before any significant moneys are spent on R&D or Product Development, a basic FTO (freedom to operate) search you be performed to ensure the idea, technology, or product is not infringing the IP rights of another party. IPstreet.com's search tools will help you avoid third-party infringement.
Although anyone can claim to inventor or create something (e.g., Al Gore created the Internet), the reality is that an idea needs to be carefully considered in context of the law. If you are serious about protecting your invention, you should contact a patent attorney or patent agent. Applying for a patent, and its subsequent patent prosecution process, does cost money. You may see ads for low-cost services to file a patent on your behalf. Such solutions are viable if your goal is to boast to your friends that you patented something. However, if you have real-world business ambitions, it is imperative that the person writing the claims of your patent is a well-qualified lawyer. The adage "you get what you pay for" is very true in the intellectual property community. Realistically, a single patent is going to minimally cost you around $10K for the application fees, legal fees to write the claims, and so on. You want to find a legal professional that is a subject matter expert in your domain (whether it is IT, manufacturing, mechanical engineering, biotech).
