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.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 Patent Your Idea
Contrary to popular belief, you can't get a patent for something that's still in idea form; you must be able to apply your idea in a concrete way. This doesn't mean that you have to build a prototype of your invention before you can get a patent. However, you have to be able to draw or describe it in enough detail so that someone else could make it and use it. Have a question?

The amount of money you need for patenting will vary depending on the type of patent application you submit. Fees may also vary according to the way you claim your ideas.patented invention
When you conduct the online patent searches, you'll be able to read the full text of the patents and see diagrams. Don't be discouraged if you do find your invention idea is already patented. You may be able to come up with a variation that's not patented...And double check the patent. Sometimes, what looks like the same invention idea may actually be quite different. Some of the free searches may not involve a complete search of all granted patent archives and patent applications for all time. You may want to consider hiring a registered patent attorney to find this information for you.
