A patent is a form of intellectual property right which enables an inventor to protect in law their creation, preventing others from copying or modifying it without permission. It is related to, but not the same as, copyright. You must file a patent with the relevant local body for it to be applicable, and you should check that no existing patent exists for a similar invention.
Patents detail the idea and invention as well as any related technical information and drawings.
