Patent
        Patents are meant to protect the chances of inventors to make money from their creations. Suppose you have an idea for an invention. How do you get a patent to protect your rights? The first step is to record your idea on paper. You must be sure no one else has invented a device just like yours. So you must examine the descriptions of similar devices that already have patents. This can be a big job and take a long time. Many inventors pay patent lawyers to do this job.
