patents, colorectal cancer, technological advances


Colorectal cancer is epidemiologically relevant worldwide because it is the fourth leading cause of death from cancer. This study aims to present the mapping of technologies related to colorectal cancer. The search took place during the months of May and June 2019. The Leans database was used, which collects global patent information. The search occurred through the term "colorectal cancer", inserted in the title or abstract fields. Patents with publication date between January 1, 2000 and June 1, 2019 were selected. Only the patents granted and those filed were filtered (patent application; granted patent). A total of 6,850 patents were identified, of which 5,445 (79.48%) correspond to patents filed and 1,405 (20.51%) are patents granted in the period from 2000 to 2019. In 2000, 47 patents on colorectal cancer were published. The quantitative growth of technologies filed and granted was constant. In 2017 there was a total of 911 applications, indicating a growth of 1938.29% in relation to the year 2000. The first patent of the period was on the APC gene mutation, associated with colorectal cancer in families of Ashkenazi Jews, developed by Laken and collaborators (2000), and belongs to Johns Hopkins University, Baltimore, Maryland, in the United States. It can be concluded that the mapping of patents is important to trace a panorama of the world technological advance, as well as it can also be used as an instrument to identify scientific articles that cite patents developed in a given time space.
