Abstract
Since January 2020, the World Health Organization announces COVID-19 outbreak a case of public health emergency of international interest, and declaring it a pandemic on March. Due to the high transmission of this disease, rate precautions have been implemented, such as the use of masks by the population, personal protective equipment (PPE), and safety protocols, mainly to health workers. Thus, we performed a patent review to evaluate the current patents related to the protective mask. The review was carried out in the patent database in the period of May 2019 to May 2020. After the process of screening and eligibility, 563 patents were selected for our analysis according to the aim of the study which used masks such as a PPE against dust particles and pathogens, mostly when it is about airborne transmission, such as viruses and bacteria. Here, an overview of the main materials used in the mask manufacturing and their efficiency was described. The results of the review showed that most of the masks used cotton, nylon, silver fiber fabrics, among others as fabrics to develop the masks. It also makes an analysis of masks composed of nanotechnology which provide high filtration efficiency. Moreover, the review also brought possibilities of masking the population, which already have been done in countries such as China and Korea and ways of sterilization for reuse of PPE during COVID-19 outbreak. Thus, this review can further researchers in the developing of masks to decrease the spread of a pandemic disease. Graphical abstract.

Abstract
The emergence of a new coronavirus (SARS-CoV-2) outbreak represents a challenge for the diagnostic laboratories responsible for developing test kits to identify those infected with SARS-CoV-2. Methods with rapid and accurate detection are essential to control the sources of infection, to prevent the spread of the disease and to assist decision-making by public health managers. Currently, there is a wide variety of tests available with different detection methodologies, levels of specificity and sensitivity, detection time, and with an extensive range of prices. This review therefore aimed to conduct a patent search in relation to tests for the detection of SARS-CoV, MERS-CoV, and SARS-CoV-2. The greatest number of patents identified in the search were registered between 2003 and 2011, being mainly deposited by China, the Republic of Korea, and the United States. Most of the patents used the existing RT-PCR, ELISA, and isothermal amplification methods to develop simple, sensitive, precise, easy to use, low-cost tests that reduced false-negative or false-positive results. The findings of this patent search show that an increasing number of materials and diagnostic tests for the coronavirus are being produced to identify infected individuals and combat the growth of the current pandemic; however, there is still a question in relation to the reliability of the results of these tests.

Abstract
INTRODUCTION Coronavirus has been responsible for several virus outbreaks since 2003, caused by SARS-CoV-1, MERS-CoV, and currently SARS-CoV-2 (COVID-19), the causative agent of coronavirus disease in 2019. COVID-19 has become a global public health emergency because of its high virulence and mortality capacity. This patent review aims to provide an overview of the patents that present possible treatments for SARS-CoV-1, SARS-CoV-2 and MERS-CoV. AREAS COVERED To treat SARS, MERS and SARS-CoV-2, researchers have filed patents for a number of therapeutic agents. Most of the treatments found were protease inhibitors aimed at proteases such as PLpro, 3 CLpro, RNA helicase, and Spike protein, or used monoclonal antibodies and interferons. In addition, the use of Chinese folk medicine and its multitude of medicinal plants with strong antiviral properties was reinforced. Thus, these therapies used in previous epidemics can serve as an aid in the new pandemic by SARS-CoV-2 and be a starting point for new treatments. EXPERT OPINION The various antiviral alternatives presented in this review offer therapeutic options to fight coronavirus infections. If shown to be effective, these drugs may be extremely important in the current pandemic.
