Is my invention already patented?
Determine if your invention is novel by doing a "prior art" or patent search, find out if someone else has already patented your idea. An inventor or hired professional can conduct a search of the USPTO records.How do i know if someone has already made and patent my idea?
i have this idea that could be worth lots of money and it would raise a certain cars safety by a lot but i dont know if some one has made it is there a website that would list patented ideas - Your best bet is to hire a professional to do a patent search for you. However, there is no way to be sure you have looked everywhere or fully considered each patent, there are just too many. However, you can get a warm fussy feeling that it PROBABLY hasn't been patented. The process of patent examination, adds another blanket of warm fussy.How Much Does It Cost For a Patent?
The U.S. Patent and Trademark Office (USPTO) establishes fees for patenting unique, non-obvious inventions. Because there are different types of patents, these fees vary, depending on those due at the time of the initial application and during the maintenance intervals required during a patent's 20-year life. A filing fee, search fee and examination fee are due with an initial application. Patent applications with more than 3 claims are subject to additional charges. It is important to note that fee structures are not static. The below represent the USPTO 2009 fee schedule and apply to patents filed on or after December 8, 2004. Initial Filing Fee - The initial filing fee for a utility patient is $330. Initial filing fees for design and plant patents are $220. Patent Search Fees - The search fee is $540 for a utility patent; $100 for a design patent; and $330 for a plant patent. Patent Examination Fees - The examination fee is $220 for a utility patent; $140 for a design patent; and $170 for a plant patent. Patent Maintenance Fees - The maintenance fee for patents is $980 at the 3.5-year interval; $2,480 at the 7.5-year interval; and $4,110 at the 11.5-year interval. Other Applicable Fees - Other fees may be necessary during the prosecution of a patent and the patent's 20-year term. These may include extension of time fees, post-issuance fees, financial service (administrative) fees and trademark processing fees. Additional fees will be incurred if a patent application needs to be appealed. Fees for Additional Claims - If a patent application contains more than 3 claims, an additional $220 is charged (per claim). The cost of more than 10 claims is $52 per claim.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.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.
