You do realize that the link you posted is just to an application for patent. Anyone can submit a patent application, it does not mean the science works or has been used to treat anything. Until it’s FDA approved it’s not applicable to Coronavirus.
Read this from International UV Association,
We would like to inform the public that there are no protocols to advise or to permit the safe use of UV light directly on the human body at the wavelengths and exposures proven to efficiently kill viruses such as SARS-CoV-2. UV light under the conditions known to kill such viruses are also known to cause severe skin burns, skin cancer, and eye damage. We strongly recommend that anyone using UV light to disinfect medical equipment, surfaces, or air in the context of COVID-19, applications that are supported by sound scientific evidence, follow all recommended health and safety precautions and to avoid direct exposure of the body to the UV light.
