The Average Cost to Patent an Invention
No entity that works professionally with the patent process publishes any average of the cost involved in patenting an invention. The U.S. Patent and Trademark Office simply publishes a list of the office fees, while the magazine IP publishes some ballpark numbers qualified with pages of discussion and the law firm Oppedahl Patent Law throws out a few numbers. state that an invention's complexity greatly determines the cost of the patent process.How To Conduct a Patent Search
you can do a patent search online. The U.S. Patent and Trademark Office (1790 - Present) and Delphion (1974 - Present) both provide free online databases. You can searching using keywords or phrases that describes your invention. Look for common terms describing the invention and its function, effect, end-product, structure, and use. The results will list the title and number of all patents related to your keywords (l976 forward only). The title link will take you to the full text of the patent. You will not be able to do a complete search online for a pre-1976 patent unless you know the exact patent number. With online patent be sure to examine other referenced patents that the inventor has listed.how to check if an idea has been patented
There is no EASY way. If your invention is a new can opener, an existing patent for the same idea may never use the words can opener. For example, it may be described in broader terms: container de-sealer or metal wall scissor. The patent offices classification system helps a bit, but not much. Inventors tend not to want to find their invention, so, they type in --can opener-- and look at a few and say they couldn't find it. You have to look for it like you want to find it. try different search terms. when you find one thats close, look at the references cited in that application and look for other patents wherein the close one was cited.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.Attorney Fees / Invention Complexity
The USPTO, IP Watchdog and every patent law firm strongly recommends that inventors hire a patent agent or attorney to prepare the application. IP Watchdog reminds inventors that not only is the process confusing, but a patent is a legal document that uses the language found in the application and patents can only be protected in court, where every word in the document matters. IP Watchdog reports that the median cost of a patent attorney is around $250 an hour, higher in urban areas (Quinn suggests hiring an experienced attorney that works in an area with a low cost of living as a way to control costs, as opposed to hiring an inexperienced attorney). Quinn states that, depending on the complexity of the invention, attorney fees for conducting a search and preparing an application with drawings usually run between $7,000 and $15,000. The more complex an invention, the longer the attorney spends researching related patents, writing up a detailed description and outlining exactly what the patent should protect. Drawings also take longer the more complex the invention is, and USPTO rewrites can be more difficult.
