A patent is one of the oldest forms of intellectual property protection, depicting an invention and giving exclusive rights to an inventor. It’s possible to get the right for a particular invention via providing an inventor or government with royalties, though moral rights can’t be transferred and will always remain with an inventor.
Before an inventor gets a patent, he must prove that his invention meets such relevant patentability requirements as novelty and non-obviousness. Then a patentee or a company fills in the application, containing a description of how to make and use the invention, information about usefulness of the invention and technical problems solved by the invention. In some cases it’s required to attach drawings illustrating the invention. After that a patentee has to wait for the “patent pending” period and only after a patent will be enforced.
