First, you should know what kind of patent you want to file. A patent is an allocation of property rights issues to a creator for his invention. In the United States, USPTO issues and considers patent applications to exclude other contenders from making profits off of someone’s idea.

To know if someone has already come up with an idea, you can go to the official website of the US Patent Office (USPTO) and search for a patent suitable for your project. USPTO has an online and offline search base in major cities around the country.

Searches for a patent can be conducted by looking into already existing patents and find out if your idea has already been patented. You should also check already existing patents and mark possible similarities. This allows you to improve your work and make it fresh. Moreover, you can avoid infringing on someone else’s work and avoid being rejected by the Office.

If online search engines are not comfortable, you can visit special libraries called Patent and Trademark Depository Libraries (PTDLs). They have complete information about patent searching, from the first patent ever issued to the latest. These networks of libraries are well-stocked with patent materials. Every state has one in major cities and you can take the help of librarians for any queries, although they will not search a patent and information for you. The USPTO maintains an up-to-date list of contact information for all PTDLs at www.uspto.gov/go/ptdl
When you receive a patent, you get a monopoly over its profits and uses. As important it is important to protect your ideas from being stolen, it is also important to make sure that your idea doesn’t seem copied to someone’s work.
