The Do-It-Yourself Patent Search
If you decide to do the patent search yourself, you have several search methods available: The USPTO (United States Patent Trade Office) Public Search Facility. The USPTO operates a Patent Public Search Facility located in Alexandria, Virginia. Here every U.S. patent granted since 1790 may be searched and examined. Many inventors like to make at least one pilgrimage to the Patent Public Search Facility. It's located fewer than 15 minutes from National Airport by taxi; Metro Rail serves it off the Blue and Yellow lines, King Street Station; and several hotels are within walking distance, so it's easy to get to and around.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.What You Can Patent
A patent provides you with the right to keep others from making and selling your invention for up to 20 years. The most common type of patent, a utility patent, protects rights in new and useful processes, machines and other things. These patents also can protect rights in non-obvious improvements made to existing things. To determine if your invention is patentable, you must first research all previous patents and other publicly disclosed inventions to ensure that no one else has already patented something similar. Because this process can be difficult and complicated, the U.S. Patent and Trademark Office recommends hiring a registered patent attorney to conduct the search for you.The Main Reason Why
You have to do (or hire someone else to do) a patent search before investing in the cost of patenting . Even if you hire someone else to do the patent search for you and that is highly recommended for beginners - do a preliminary search yourself and bring that research to the intellectual property attorney or agent that you hire . Doing so will save you money, plus provide the other benefits mentioned above.Is my idea already patented?
Most inventors dont really want to find their invention in someone elses patent, so the spend 5 minutes looking and then declare that they can't find it. It takes longer than that. If your invention is a mouse trap, you might find it by searching for those words...but the killer patent might instead describe a rodent restriction device or an automatic small animal containment system. Look for it like you want to find it. Talk to a registered patent attorney for immediate advice on protecting your idea (in the form of a provisional patent) while you determine if it is worth pursuing, in view of a preliminary search of related inventions, patented or not. Even if you don't find any "patents" showing your idea used in an invention, it could still be unpatentable because someone else used it or described it before you filed your provisional application.
