A trademark is a sign, logo or design of some kind that distinguishes a particular product or service (or its provider or source) from others.

A trademark identifies a particular product, service, or it's provider or source, from others, particularly in the same industry, but also in general. Often a mark will appear on product packaging, printed communication, and buildings.

Many countries require registration of a trademark in order for the owner, which may be an individual, company, or other legal entity, to pursue legal action for infringement.

Trademarks can be designated with the superscript TM (™), or the R in circle ® for registered trademarks.
