What are the differences between a patent, trademark, and a copyright? What is meant by counterfeiting?

What will be an ideal response?

A patent is a formal legal document that gives an inventor the exclusive right to make, use, and sell an invention for a specified period of time. Typically, this invention should be a new, novel, and/or non-obvious creation. On the other hand, a trademark is defined as a distinctive mark, motto, device, or emblem that a manufacturer affixes to a particular product or package to distinguish it from goods produced by other manufacturers. A copyright establishes ownership of a written, recorded, performed, or filmed creative work.

Counterfeiting is the unauthorized copying and production of a product. An associative counterfeit, or imitation, uses a product name that differs slightly from a well-known brand but is close enough that consumers will associate it with the genuine product. The worst form of counterfeiting is known as piracy, which is the unauthorized publication or reproduction of copyrighted work. Counterfeiting and piracy are particularly important in industries such as motion pictures, recorded music, computer software, and textbook publishing. The United States in particular has a vested interest in intellectual property protection worldwide since it is home to many companies which have patents, trademarks, and copyrighted materials.
