When we think of a globalized world, whose development is based on internationalized actions, the ease of communication, access to information, cultural and commercial exchanges and the technological development that they ignite immediately come to mind. Clearly, much is earned from internationalization, however, what is lost is rarely considered. A rigorous assessment of the changes that internationalization represents for a nation is needed, in order to understand its effective costs and handle it properly. It is a common sense that the main impact of internationalization is on the culture of a people. Internationalization, as a mechanism to facilitate sharing of information, products, knowledge, certainly has an impact on cultural diversity, however, it is not always clear if it is positive or negative. Regarding intellectual property, it often influences authorship recognition and, therefore, ownership of innovative creations. Often, cultural issues affect the way in which authorship recognition occurs, especially when it comes to different ethnicities and genders. In this chapter, we will explore the aspects of intellectual property related to traditional knowledge that influence cultural and gender diversity, worldwide, evidencing their pros and cons, aiming to collaborate to public policies to bridge the gender gap and truly protect diversity.
