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.Don't Talk About It
If the invention has been described in a printed publication anywhere in the world, or if it has been in public use or on sale in the United States before the date that the applicant made his/her invention, a patent cannot be obtained. If the invention has been described in a printed publication anywhere, or has been in public use or on sale in this country more than one year before the date on which an application for patent is filed in this country, a patent cannot be obtained. In this connection it is immaterial when the invention was made, or whether the printed publication or public use was by the inventor himself/herself or by someone else. If the inventor describes the invention in a printed publication or uses the invention publicly, or places it on sale, he/she must apply for a patent before one year has gone by, otherwise any right to a patent will be lost.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.Has someone else already done this?
As an inventor, one of your first thoughts when you come up with the Mother of All Ideas is probably, Has someone else already done this? The only way to know for sure if you're the first is through a patent search. The search will tell you if your idea has been patented already and, if so, whether the patent is still in force. Here's how you do it.Direct-Hire Professional Search
If you want to save lawyer fees and mark-ups, consider going directly to a patent search firm. Searchers are best found through inventor grapevines, inventor associations, or university intellectual property departments. In larger cities, you can also check the Yellow Pages under "patent searchers." But be careful not to fall into a trap set by some disreputable invention marketing organizations. They list themselves in the phone book under "patent searchers" with a toll-free number. This is another way they hook unsuspecting inventors into service contracts. Get all the facts up front. Some reputable searchers ask for money up front if they don't know you. This is understandable. Just be sure you get the cost of the search beforehand, and get—and check—references. The cost to search a utility patent in the Washington, D.C., area runs between $500 and $1,000. It is roughly $100 per hour for a competent search. Once the search has been completed, if you want to obtain an opinion on the patentability of your invention, add the cost of your lawyer. If you need to show a prospective licensee that your invention has a good shot at a patent or that it's unlikely to infringe on an existing product, a letter from competent patent counsel may do the trick.
