What Does New or Novelty Mean?
In order for an invention to be patentable it must be new as defined by patent law . An invention cannot be patented if: The invention was known or used by others in the United States, or patented or described in a printed publication in the United States or a foreign country, before the current applicant filed for his or her patent. Someone else has made the same invention as you did. The invention was patented or described in a printed publication in this or a foreign country or in public use or on sale in this country more than one year prior to the application for patent in the United States. You or somebody else revealed your invention more than a year ago to the public.What cannot be patented?
Laws of nature, Physical phenomena, Abstract ideas, Inventions which are considered not useful or possible by the USPTO for example perpetual motion machines; or offensive to public morality.Who can apply for a patent?
A patent must be applied for only in the name(s) of the actual inventor(s). However, the inventor can sell or assign the patent to someone else. Prior art includes any patents related to your invention, any published articles about your invention, and any public demonstrations. This determines if your idea has been patented before or publicly disclosed making it unpatentable.How do I know if my idea is patentable?
First, check to see if your idea qualifies. Second, learn the basics of the patenting process. Next, do a search for of all previous public disclosures that concern your invention. These public disclosures are called prior art. A registered patent attorney or agent can be hired to do a patentability search for prior art, and a big part of that is searching for U.S. and foreign patents that compete with your invention. After an application is filed, the USPTO will conduct their own patentability search as part of the official examination process.More on Prior Art
Remember, while patent searching is a big part of prior art , it is not everything. If someone has made your invention before you without patenting that still counts against your patentablity. A complete search for prior art might include for example: searching non-patent literature such as any magazine, newspaper, or trade paper article written about inventions like yours also a complete search would include international patent documents (online) and not just those found at the USPTO. Do not make the mistake of believing that just because no one else is selling your product that it does not already exist. After determining that your idea is patentable and qualifies for a patent - you now need to decide if the expense of patenting is worth it.
