Definitions of brand related terminology

Here's my attempt at defining brand related terms (more refinement required but I hope you get the general idea) -

Brand equity refers to the view that a brand can be regarded as an asset capable of generating or contributing to the generation of revenue.

Brand value - that the brand is worth something.

Brand loyalty -  customer preference or affinity for a particular brand over others built up over time comprising quality such as trust or promise of a certain standard or image.

Brand management has its roots in Procter & Gamble in the 1930a.  It was an idea from Neil McElroy to set up "brand team" to be in charge of one brand. It is a business organization idea of defining team based on product line instead of along functional level.

The brand team manages all aspect of that product line such as shipment, advertising,  local adaptation.  They  take full responsibilities for that product line.  Because of its success, the idea is emulated by many companies with multiple brand on their portfolio.

Goodwill - in legal speak -  under certain English law tradition,  a property right that arises from promotion of a brand or packaging; such that another party can be stopped from riding on the goodwill attached to the brand or packaging.  Goodwill does not depend on trade mark registration.  The legal terminology for misappropriation of goodwill is passing off.  Legal Nazis will insist that goodwill is not the same as business reputation.

Trade dress - a legal concept that protects the look and feel of a packaging.  In Australia or the U.K., the analogy would be goodwill/passing off.

Trade mark - in its most basic form - an indicia of trade origin - at this level - it could include a name, logo, color scheme such as color green associated to British Petroleum, shape of packaging such as the Coca-Cola bottle.   But it is unusually harder to claim right to exclusive use to a single color or shape.

Brand protection - a corporate function in protecting the brand against imitation - identical copy or lookalike.  The former is usually referred to as counterfeitirng.
