A patent is a license used to protect the rights to a product or creation you’ve invented. There are two types of patents: utility patents and design patents. The rights allow someone to make and sell a product or service for a certain time, anyone else can’t copy the product or service. For example, a patent is a protection against copying the production method used to create Hershey chocolate company. A patent lawyer help with legal procedures to protect your rights such as filing patent applications and oppositions to granted patents. Here is a list of categories you can generally patent: computer software or hardware, chemical processes or formulas, furniture design, jewelry, instruments, medical devices. Some things that you can’t patent are laws of nature, physical phenomena, abstract ideas, non-useful or offensive inventions, works of literary, dramatic, musical, or artistic nature (these can be copyrighted). To get a patent first announce your invention, then apply for the patent within one year of the declaration.
