Types of Designs available

  • Industrial Design or Model
  • Utility Model (Functional Design)

Novelty Requirements: 

An industrial design or utility model is new if it has not been disclosed in any appropriate manner in Angola or abroad in such a way as to enable it to be exploited by anyone skilled in the art. 

The design shall not be considered novel if it has already been the subject of an application, even where the application is void or forfeited, in Angola or abroad, or if it has been used in a well-known manner or has fallen in any way into common use. 


Utility Model: 
In Angola a utility model is more like a functional design than a utility model in the true sense.

All new arrangements or shapes obtained or introduced in articles such as tools, work instruments or utensils which enhance or improve their conditions of use or utility may be registrable as a utility model. 

Protection is granted exclusively to the specific and novel shape which renders possible the increase and enhancement of the utility and use of the object to which they are intended. 

Industrial Design or Model: 
Industrial models are all plastic shapes, either associated or not to lines or colours, which may be used as a pattern in the manufacturing of a handicraft or industrial product.

An industrial design is any new arrangement or set of lines or colours that may be applied, for an industrial or commercial purpose, in the ornamentation of a product by any manual, mechanical or chemical process, whether simple or combined. 

Utility Models and Industrial Designs or Models: 
Only novel industrial designs or models and those that, although they are composed of known elements, produce original combinations that lend their respective subject matter an overall appearance that has its own characteristics, may be registered. 

Please note that an industrial design or utility model application may relate to a single industrial design or utility model only.

What may not be protected as a Utility Model or Industrial Design

The following are not protected as utility models or industrial designs:

  • Those which, by their description and claims, are regarded as inventions;
  • Sculptures, engravings, paintings, architectural works, photography, enamels, embroidery and any other models or designs with a purely artistic character;
  • Models or designs contrary to good public order and accepted principles of morality;
  • Those which are unpatentable in terms of the patent provisions.

Please let us know if you require a list of what is not patentable in Angola.

Filing Requirements:

  • Power of Attorney (notarised and legalised) (can be late filed)
  • Drawings, photographs or a sample of the industrial design or utility model (required on the day of filing)
  • Indication of the kind or class of the product for which the industrial design or utility model will be used
  • Certified copy of priority document, if priority claimed (can be late filed within three months from filing)
  • Portuguese translation of Priority Document (can be late filed within three months from filing)
  • Assignment (notarised and legalised) (can be late filed)

Deferred Publication: 

Not possible 

Substantive Examination: 



It is not possible to amend an industrial design or utility model. 

Any alteration to the essential elements of the industrial design or utility model must always entail filing of a new industrial design or utility model application, save where the changes are the result of the enlargement or reduction of the industrial design or utility model, or differences or changes made to the colour or material of the industrial design or utility model by its owner. 

Average Period from Application to Registration: 

Three to four years. 


Industrial design applications are published for opposition purposes. A third party may file a notice of opposition within sixty days (period is extendible) from the publication date. 

Duration and Renewal: 

Design registration is valid for an initial term of five years from the date of deposit of the application for registration, which term is extendible for two further terms of five years each. Provided that renewal fees are paid, each five-year extension is granted without a formal request for extension having to be lodged. 

Please note that renewal fees fall due annually from the first anniversary of the filing date. A grace period of twelve months is provided for late payment of the renewal fee. 


A registered industrial design or utility model will be forfeited if there is failure to exploit the product covered by the industrial design or utility model within one year from date of registration.
