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 Does Useful Mean?
