Applicant: the inventor or his assignee (whether an individual, firm, company or corporation).

Foreign applicant: must appoint a representative residing in the country.

Novelty: an invention is not considered new if it is in the state of the technique, that is, if it has been made public, by means of an oral or written description, or by use, or any other means sufficient so as to permit its execution before the day of filing of the patent application or the recognized priority. An application does not lose its novelty if such disclosure is the result of a clear abuse in detriment of the applicant or the person holding his/her rights or the fact that the applicant or person holding the rights may have exhibited the invention at an officially recognized exposition or fair held in one of the member countries (Andean Community countries: Bolivia, Ecuador, Colombia, Venezuela and Peru) or that he may have carried on experiments to prove its industrial application.

Inventive level: if, for an expert, the invention has not evidently been derived from the state of the technique.

Industrial application: if the object of the invention can be produced or used in any kind of industry (any productive activity, including services).

The following are not considered inventions: (1) discoveries, scientific theories and mathematical methods; (2) the whole or part of living beings as they are found in nature, natural biologic processes, biological material found existent in nature and biological material that can be isolated; including genoma and germoplasma of any living being; (3) literary or artistic works or any other aesthetic creation, protected by copyrights; (4) plans, rules and methods for the exercise of intellectual activities for commercial economic activities; (5) computer programs or software as such; (6) the ways in which data are presented.

Unpatentable inventions: (1) inventions whose commercial exploitation within the territory of a country member should be impeded in order to protect public order and moral; (2) inventions whose commercial exploitation in the respective country member should be impeded in order to protect the health or life of people, animals or to protect plants or the environment; (3) plants, animals and biological procedures essentially used to obtain them, which are not non-biological or microbiological procedures; (4) therapeutical or surgical methods to treat humans or animals as well as diagnostic methods applied to human beings and animals.

Unity of invention: a patent may only cover one invention, or a group of inventions which are interrelated so as to constitute one sole inventive concept.

Priority: a priority of one year may be claimed from applications filed in countries which are members of the Paris Convention or applications filed in any Andean Community country.

Application kept secret: as long as the aforementioned notice has not been published, unless the applicant provides a written consent, the file cannot be consulted by third parties. Once the patent has been published, the file becomes public and can be consulted.

Amendment of application: possible, but changes cannot involve an extension of the scope of the invention or the information disclosed in the original application.

Nullification may be filed at any time. When the above causes are only applicable to some of the claims, or to a part of one claim, the nullification shall be stated only with respect to such claims or part of a claim, as the case may be.

Validation of invalidated patents: not possible.

Infringement: the holder of a patent can initiate infringement and indemnity actions. The holder can sue for damages against whoever has been working the patented process or product, without his/her consent, when said working has taken place between the publication date of the patent application and the granting date of the patent. If the patent covers a process to obtain a product, it is up to the defendant in question to prove that the process he has used to obtain the product is different from the process protected by the patent whose infringement is being claimed. The defendant’s legitimate interest as regard to the protection of his commercial and manufacturing secrets will be taken into account in producing evidence to the contrary.

Penalties: penalties for infringement are: cessation of the manufacturing process, the destruction of the product, the closing of the business or any other measures deemed appropriate, confiscation or the imposing of a fine, depending on the seriousness of the infringement, without prejudice to any other civil or penal action that may be applicable.
