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.How long does patent protection last? (As of year 2005)
Utility and plant patents are granted for a term which begins with the date of the grant and usually ends 20 years from the date the applications were filed. You must make the timely payment of the appropriate maintenance fees. Design patents last 14 years from the date you are granted the patent. No maintenance fees are required for design patents.how do i know if my idea has been patented
Checking to see if your idea has already been invented before applying for a patent saves you time and money. A patent gives you exclusive rights to the product or idea you invented and a way to fight intellectual property theft. The United States Patent and Trademark Office checks your idea against existing patients and pending applications during the application process. Your patent will be rejected if it's too similar to an existing patent, costing you the application fee. While you might find ideas that are similar to yours, you can still patent your idea as long as you show on the application how your take on the patent object is new. You can search for existing patents using various methods, including the USPTO's online database or in person at a field office.What can be patented?
Utility patents protect inventions that are a novel, nonobvious, and usefulProvisional Application
If you have a patentable invention, filing a provisional patent application can provide temporary protection of your intellectual property rights while you develop your idea further or seek funding. Provisional applications have a lower fee than non-provisional applications -- and you don't have to make formal claims or provide the same level of detail about your invention. Additionally, provisional applicants don't have to wait for the USPTO to examine the contents of the application. Your provisional application is valid 12 months from the date you file it -- and you can use the phrase "patent pending" in connection with your invention during that time.
