Difference between mark, label and logo

good question

You already have the answer.

A trademark may be an insignia, label, name, sign, logo, device, signature, numerals, packaging, shape of goods, colour combination etc. In other words, a trademark is a visual symbol used in relation to any goods or services to indicate some kind of trade connection between the goods and services and the person using the mark. It usually identifies the product and acknowledges its unchanged quality and helps to advertise the product. (Please refer to  Section 11(6) and 11(7) of  The Trademarks Act.)

A logotype, commonly referred to as a logo, is a graphical symbol created for an individual company or product. It is designed to communicate quickly, and to be a distinctive and easily recognizable symbol.( India does not have a separtet defination)

In trademarks, label refers to an informative display of written, printed or graphic matter like a logo or title, affixed to goods or services for identifying their source. A label can be fixed on the wrapping, packaging or container of a manufactured product or on the packaging or surface of a natural substance. ( As per state statute of Georgia U.S.A,  India does not have a seperate defination)
