Unfair competition is the practice contrary to honest practices in matters of industry and commerce. It refers to all those activities of dubious honesty (without necessarily committing a crime of fraud) that a manufacturer or seller can carry out to increase their market share or eliminate competition.
Some unfair competition practices are:
Price dumping, that is, selling at a price lower than the cost of the product.
Deception in making buyers believe that the product has a different price than the real one.
Denigration by spreading false information about the products of the
competitors, or publish non-relevant comparatives.
Confusion when looking to look like a competitor so that the consumer buys your products instead of the competitor's. It is very common to use similar marks or designs for this.
Diversion of customers and exploitation of the reputation of others are other types of acts of unfair competition.
