Utility patents protect inventions that are a novel, nonobvious, and useful, such as: process innovations, machine innovations, manufacturing innovations, compositions of matter, or incremental improvements from foundational innovations. The three patentability requirements: New and Novel: For a United States patent the invention must never have been made public in any way, anywhere in the world, a year before the date on which an application for a patent is filed. In other countries, you have no one year grace period and require absolute novelty. Original and Nonobvious: An invention involves an inventive step if, when compared with what is already known, it would not be obvious to someone with a good knowledge and experience of the subject, for example, if you just make cosmetic changes that is obvious. Useful: This means that the invention must take the practical form of an apparatus or device, it has to do something.

A utility patent application can be filed provisionally or unprovisionally. The non-provisional application establishes the filing date of your patent application and begins the examination process. Your patent application will be examined by the USPTO. A provisional application only establishes your filing date and expires automatically after one year. You may file a provisional application when you are not ready to enter your application into the regular examination process. A provisional application establishes a filing date at a lower cost for a first patent application filing in the United States. A provisional application allows the term "Patent Pending" to be applied to your invention.

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).

Laws of nature: Galileo would not be able to patent his findings from his experiments at the Leaning Tower of Pisa. Physical phenomena: Patent law classifies physical phenomena as products of nature. Thus, if your invention occurs in nature, it is a physical phenomenon and cannot be patented. Abstract ideas: Abstract ideas are concepts like pure mathematics and algorithms. You cannot patent a formula. However, you can patent an application of that formula. Thus, while you cannot patent a mathematical formula that produces nonrepeating patterns, you can patent paper products that use that formula to prevent rolls of paper from sticking together. Literary, dramatic, musical, and artistic works: These can be Copyright protected. Inventions, which are considered not useful or possible: For example, the USPTO will not issue a patent on a perpetual motion machines; or offensive to public morality.
