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.You Can't Be Too Obvious
Even if you don't find the prior art to prove it - you will not get a patent if your invention is not different enough from similiar inventions that are already out there. A patent maybe refused if the differences between your invention and another invention are too obvious. Your invention must be sufficiently different from what has been used or described before that it may be said to be nonobvious to a person having ordinary skill in the area of technology related to your invention . For example, the substitution of one material for another, or changes in size, are ordinarily not patentable. You can't paint it red and make it twice as big and expect a patent. Another example of "nonobvious to a person having ordinary skill in the area of technology related to your invention" could be the following. An electronics engineer looks at a circuit board and observes that it is just like another circuit board except that a few parts are substituted. Someone who is not familiar with circuit boards may not understand that the two boards are very similar, however, someone with training thinks that it is obvious. You would want the electronics engineer to look at the circuit board that you want to patent and say, "heah, why didn't I think of that!"Do a Patent Search
Would you like to see a real patent ? You can! Finding patents is almost like being a detective. A patent search is something that all inventors have to do before they can patent their invention. It lets inventors find out if anyone else has ever invented the same invention. Another benefit is that conducting a patent search is also a great way to find out about the history of old inventions.Why is classification so important?
While it is possible to search patents using keywords, the best way to conduct a comprehensive patent search is by classification. Classification helps bring together similar devices and concepts, even when different terms have been used to describe them. When a device is truly new, terminology is not set. For example, before personal computers a mouse was nothing more than a rodent. The inventor of the first "Computer Input and Display Control" would not have found related devices by searching the keyword "mouse." A classification is used both as a tool for finding patents (patentability searches), and for assisting in the assignment of patent applications to examiners for examination purposes. Classifications have definitions. Classifications have hierarchical relationships to one another.Different Ways To Patent Search For Inventions
Here are three tutorials on the three basic ways to conduct a patent search. Remember these are introductory tutorials, and not a substitute for an advanced or professional patent search. Patent Search by Patent Number: This is the easiest way to find out about an invention! Patent Search by the Inventor's Name: This sometimes requires a little detective work, but you can do it! Patent Search Using Words: This is the most challenging and fun way to look for inventions!
