INTELLECTUAL PROPERTY, TRADEMARKS, AND PATENTS
Protecting intellectual and industrial property is an essential part of life for any business, brand, creator, innovator, or growing project.
A name, identity, image, innovation, design, technical know‑how and commercial distinctiveness are all assets that require a structured legal framework and a consistent strategy for their protection.Â
At Armandino Lopes Advogados, we provide legal support to companies, business owners, professionals, inventors, and rights holders who want to protect their distinctive signs, build value from intangible assets, or respond when others use them without permission.
Our work focuses on preventing risk, identifying the right form of protection, guiding clients through registration applications, and defending their interests in matters that directly affect their activity, market position, and the value of their business.
If you are looking for legal support in intellectual property, trademarks, and patents in Guimarães or anywhere in Portugal, it is essential to plan that protection early and shape it around the reality of your project.Â
This is an area where acting early makes all the difference. A name or distinctive sign may already be in use without proper protection. An innovative product may need a legal framework in place before it reaches the market. A design may carry real commercial value and be worth registering.
At Armandino Lopes Advogados, we handle these matters with care, discretion, and a practical outlook, helping clients protect what sets them apart, gives them value, and sustains their work.
Situations where legal support is essential
Protecting trademarks
A trademark is one of a company's most important distinctive assets and should be properly protected before or during its use in the market.
Registering national trademarks
When the protection sought is focused on Portugal, the application should be made through the national route.
Protecting trademarks in the European Union
When the rights holder's interests extend beyond the domestic market, it can make sense to consider EU-wide protection through the EUIPO (European Union Intellectual Property Office).
Patents and inventions
Protecting an invention can be decisive for projects with a technical, industrial, or technological component.
Protection of intangible assets
For many companies, the most valuable assets are not physical but distinctive, creative, technological, or reputational, and these call for the right legal strategy.
Counterfeiting
Industrial property law provides mechanisms to act against the unlawful use or counterfeiting of protected rights.
Misuse by third parties
Whenever there are signs of misuse, imitation, reproduction, or someone trading off the reputation of a brand or creation, it is important to look at the response quickly.
