The Renaissance of Trademarks

There is very little documentation of how marks were used between the fall of the Roman Empire and the beginning of the Renaissance. The purpose of marks changed rapidly during this period. Marks were first used to identify the maker for the protection of the consumer. Their use rapidly spread to identifying a maker with a guild and to protecting the monopolies of the guilds. Gradually in this period marks were recognized as a benefit to the maker. During a time when advertising was considered an unfair advantage, a maker's reputation would be carried with his mark. Eventually the property value of marks was recognized, although the laws protecting this value were vague.
