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.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.How to Patent Your Idea
Contrary to popular belief, you can't get a patent for something that's still in idea form; you must be able to apply your idea in a concrete way. This doesn't mean that you have to build a prototype of your invention before you can get a patent. However, you have to be able to draw or describe it in enough detail so that someone else could make it and use it. Have a question? Get an answer from a lawyer now!
