USA Patents: only has coverage in America, but it’s a start
The USA patents are only legally recognized in America, but this is a necessary start if you are an American. The application process from the USPTO is very thorough and complex with its approval process. This required preparation will help your patent be easier to be accepted by the WIPO if global protection is needed.
The process of filing for a patent in America is with the USPTO. The first step is to have an original idea that would be commercially viable. Once this is done, the application process should commence. The next step is to review the data base at the USPTO for past patents and see if your idea is already protected. There is no need to reinvent a device that already exists. That would just be a waste of time.
Once you are certain your idea is new and original as far as the USPTO is concerned, then proceed with the application process. The next step would be to develop the invention or device so a working prototype can be tested. This is necessary so all possible benefits of your invention will be known. If you apply for a patent then discover new benefits, you will have to apply for another patent to cover those benefits.
While developing the working prototype, keep immaculate records. These, along with all the drawings that you used to create your invention, will need to be submitted to the USPTO as part of your application.
Then an abstract of what your invention is and what benefit it provides needs to be written. Once all of these things are done, you are ready to fill out the actual application itself.
