Do you have a good idea? Getting a patent in Illinois is the same as any other state.The patent application is filed with the United States Patent and Trademark Office (USPTO). Compounded drugs are not FDAapproved. This means that FDA does not verify the safety, effectiveness or quality of compounded drugs before they are marketed. A provisional patent application is not legally binding or patent your invention, but it does give you a year from filing date to submit forms and payments. The first is whether it is possible to obtain a patent on an invention that involves a combination of known, "off-the-shelf" parts. Smith was an interference priority contest between alleged inventors of the use of two known compounds as insecticides. Endotoxins can be detected using routine techniques known in the art. Patent cliffs are particularly salient in the pharmaceutical industry, when generic drug makers may begin grabbing market share.
