Patents are used often to both indicate and support the investigative work and technology development of a Country. These are special documents for not only do they contain primary information, they also have different authors, legal claims, complex life cycle and rights of exploitation. Patents are consulted in internet databases, which are often subjected to OMPI standards. The SIC manages said documents in Colombia. Data Curation is a process in Digital Curation. This process controls and creates data so that it can accomplish the process they were created for. Thusly it is inferred that with a competent data curation patents could be managed easily in databases. The objective of this investigation is to identify the elements in Data Curation that allows a better management of Colombian patents. This investigation used the Espacenet database for its simplicity in search engine and high standards and control. It also used the Colombian patents in Food Chemistry during 2002 to 2012 for analysis. As a result, it was found that Colombian patents did not ha a control about the quantity and type of subject descriptors for a patent and a normalization of the data that relates one patent to another.
