The Poor Man's Patent is a Myth
One of the undying myths of Patent World is that there is such a thing as a Poor Man's Patent. If you've never heard of it, the poor man's patent involves writing out a description of your invention and mailing that description to yourself. The transmission of this description through the mail and the cancelling of the postage by the Post Office is supposed to establish a date of invention for you. That way if someone steals your invention or comes along and invents it independently, you have "proof" that you invented it first. The proof is in the sealed envelop and the date the postage was cancelled.What Does New or Novelty Mean?
In order for an invention to be patentable it must be new as defined by patent law . An invention cannot be patented if: The invention was known or used by others in the United States, or patented or described in a printed publication in the United States or a foreign country, before the current applicant filed for his or her patent. Someone else has made the same invention as you did. The invention was patented or described in a printed publication in this or a foreign country or in public use or on sale in this country more than one year prior to the application for patent in the United States. You or somebody else revealed your invention more than a year ago to the public.What Does Useful Mean?
The patent law specifies that inventions must be useful, which means have a useful purpose. Being useful also includes operativeness, meaning that an invention must operate or perform its intended purpose.Non-Provisional Application
Although you can convert a provisional application into a non-provisional application, the USPTO recommends filing a separate non-provisional application that references the earlier provisional one. Doing so can extend the time your invention is protected by up to one year. A non-provisional application includes a lengthy written document with a description of your invention and all the things you claim you invented, as well as drawings, an oath or declaration and fees for the filing, research and examination of the application. The USPTO recommends using a registered patent attorney to draft and file your non-provisional application. USPTO regulations include specific requirements for the format of applications and the necessary drawings -- and examiners reject applications that don't meet these requirements.What Is A Patent?
It is just like a property right for the inventor. All U.S. patents are issued by the United States Patent and Trademark Office or USPTO. Most patents last for twenty years. The twenty years begins on the date the application for a non-provisional or provisional patent was first filed. A patent gives you the right to exclude others from making, using, offering for sale, or selling your invention in the United States or importing your invention into the United States. Once a patent is issued, it becomes your responsibility to enforce the patent, the USPTO will not enforce your rights for you. From the USPTO you are only granted rights that are honored within the United States, U.S. territories, and U.S. possessions.
