In reference to the patent: WO2015152722A3
Is prazza inc the patent owner or the licensee?
Neither. Prazza BV is the applicant or owner, but not the "patent owner" or a "licensee".
This is a PCT application. PCT applications can never themselves become a patent. Because of this, it would be incorrect to call the applicant a "patent owner". Similarly, because it will never be a patent, it cannot be enforced. Because of this, it cannot be licensed, and so there cannot be a licensee.
The purpose of a PCT application is to buy the applicant additional time in which to select the countries to proceed in. In those countries, a national phase application will be filed, usually around 30 months from priority. Each of these national phase applications may become a patent, and so those may have patent owners or licensees.
