Organization and Operations | Note 1 – Organization and Operations Focus Universal Inc. (“Focus” or the “Company”) was incorporated under the laws of the State of Nevada on December 4, 2012. The Company is a universal smart instrument developer and manufacturer, headquartered in Ontario, California, specializing in the development and commercialization of novel and proprietary universal smart technologies and instruments. Focus Universal Inc. is also a provider of patented hardware and software design technologies for Internet of Things (“IoT”) and 5G. The Company has developed what it believes are five disruptive patented technology platforms with 27 patents and patents pending in various phases and 8 trademarks to solve what it believes are the major problems facing hardware and software design and production within the industry today. These technologies combined have the potential to reduce costs, product development timelines and energy usage while increasing range, speed, efficiency, and security of the IoT and 5G networks. The smartphone or other mobile device serves as the foundation, where the user can see the sensor readouts and together with the Ubiquitor device, performs the functions of multiple traditional scientific and engineering instruments. The Company believes this product could replace traditional, wired stand-alone instruments at a fraction of their cost. The Company has multiple subsidiaries, including Perfecular Inc.
