We prevent and defend against disputes involving unfair competition and unlawful advertising, taking action through out-of-court settlements, before Autocontrol, and in court when necessary.


“Year after year, the market recognizes Elzaburu for its deep technical expertise and unparalleled litigation capabilities.”
Unfair practices and unlawful advertising can directly affect a company’s reputation, competitive position, and the value of its intangible assets. When a dispute arises, it is essential to assess the market, the message, the channel, the rights involved, and the commercial impact of the action.
Since 1865, we have provided advice on industrial and intellectual property, assisting with the protection and defense of trademarks, designs, copyrights, trade secrets, and other assets that are often at the heart of these types of disputes.
Our approach combines prevention and defense: we review campaigns, advertising materials, and new digital formats to anticipate risks; we seek negotiated solutions whenever possible; and we take action before Autocontrol or in court when our defense requires it.
As an agency, law firm, and consulting firm, we approach every matter from every angle, combining legal strategy, expertise in intangible assets, and business acumen.

We take a dim view of conduct that causes confusion, imitation, exploitation of another’s reputation, comparison, or practices that may distort competition in the market.
