Patents are documents about inventions that provide legal protection from which we can learn about technological development. Firms hold the monopoly of producing the relevant technology for a certain period of time, and in order to protect their technological superiority, they prepare the invention notification forms and complete their official applications to the patent office. The number of patents is a strong indicator of the R&D activities of a firm, country or region. For this reason, it is possible to write a large number of scientific articles that specifically analyze a technology or a region. Thus, what does society think of these official monopoly documents? One of the ways to find out what the society thinks about a subject is to follow the flow on the social media channel twitter. This study presents a partial analysis of what the public is talking about on twitter about patents.
