Are not considered as inventions:

  1. Theoretical or scientific principles;

  3. Schemes, plans, rules and methods for performing mental acts, games or business and mathematic methods;
  4. Software;
  5. Methods and ways of setting forth information
  6. Aesthetic creations and artistic and literary works;
  7. Surgical, therapeutical and diagnostic treatment methods for human being and animals, and
  8. Combinations of known inventions, mixtures of known inventions or mixtures of known products, their variations of use, shape, dimensions or materials, except that it is in facvt their own combination or fusion so that they cannot function separately or that their qualities or characteristic functions be modified to obtain an industrial result or use not obvious for an expert in the art.

For items d) and f) above (not considered as inventions) protection is granted through Copyright Law. Protection is granted for almost all new and useful invention, irrespective of the technological field on which it was developed. Consequently, protection is granted, inter alia, for chemicals, pharmaceutical compounds; alloys, inventions in which microorganisms are used, applied to or derived from, biotechnological processes for obtaining drugs, medicines in general, beverages and foodstuffs for human consumption, fertilizers, plaguicides, fungicides and products with biological activity.

Patentability is excluded only for inventions related to essentially biological processes for obtaining, reproducing and disseminating plants and animals, plant varieties and animal races, naturally occurring biological materials as found in nature, genetical material, and inventions related with living material comprised by human body.

A Utility Model is granted for those simple innovations consisting of changes in configuration or new arrangements of parts and which makes possible obtaining advantages as to their utility and/or function. An Industrial Model will be understood to be any three dimensional form which serves  as typor or mold for the manufacturing of an industrial product and which gives it a special appearance, so long as it does not imply technical effects. For example, a new shape for a bottle or a chair can be registered as a model. The protection given by a registered model is based on the visual appearance of the article and therefore this form or protection is useful where the article itself is not new but the shape is new indeed.

An Industrial Drawing will be understood to be any combination of figures, lines or colors which are incorporated into an industrial product for purpose of ornamentation and which gives it a peculiar and unique aspect. As with patents, it is important not to show your new design to other people before tou have applied for a Design Registration.
