Table 5: Articles that focus on the use of disinfection chambers. The United States is a powerhouse in the development of solutions in several areas, including surface disinfection, probably because of the promotion of a competitive scenario with the participation of multinational companies, which increases the demand for the development of these technologies [93]. This may be one of the reasons why it is one of the preferred markets for the protection of technologies developed by other countries. Given that they are world powers, it is expected that competitors want to protect their technologies in the United States before it is developed in the country. In analysis performed by the DWPI database in relation to this result, 45% of the global requests in these results are granted, which indicates the protection for active patents (alive) in the relevant markers, and 55% of this set of results are pending as requests. To better understand the results, countries or organizations with higher percentages point to new or growing markets, while those with lower order rates may indicate established markets or areas of low growth. The United States, South Korea, and China are at 18.11%, 12.81%, and 10.16%, respectively, so they are the most promising markets and in greater competition in relation to the development of disinfection chambers with the use of O3(g) or O3(aq). In the case of Brazil, which consists in 3.98% of deposits, only one patent application was from a Brazilian company (Futura Industrial e Commercial LTDA). The document refers to a utility model of a sterilization and deodorization cabin that uses O3(g). The purpose of the system is the general sanitization of garments and objects. The remaining percentage consists of applications made by companies from other countries, mainly by TSO3 Inc., Canada.
