An important aspect of the
patented technology referred to in the preceding paragraph is the integrated structures of high-density arrays of nano-sized solar cells
as part of hydrogen production nanoparticles. The technology enables manufacturing of ultra-thin sheets for solar hydrogen production,
requiring substantially less material as compared to conventional solar cells used in rooftop power applications.  

On March 21, 2014, we jointly
filed a provisional application with the University of California, Santa Barbara for the “Multi-junction artificial photosynthetic
cell with enhanced photovoltages.” Thereafter, we filed a non-provisional application on March 16, 2015 and a corresponding PCT
Application on March 17, 2015. These applications cover our semiconductor designs to enhance the photovoltages of the nano-sized solar
cells in the PAH structures. The semiconductor designs stacking multiple junctions inside the PAH structures would be an efficient and
economical solution for the photovoltaic and the photoelectrochemical industries. Patents were granted in Australia in April of 2018,
China and Europe in March of 2019, and in the U.S. as United States Patent No. 10,100,415 in October of 2018. The last patent from this
international application was granted in India in October 2022. This patent expires on October 21, 2036.

On September 26, 2016, we
filed jointly with the University of Iowa a provisional application for “Integrated Membrane Solar Fuel Production Assembly”
to protect the intellectual property for our generator housing system that safely separates oxygen and hydrogen in the water-splitting
process without sacrificing efficiency. This device houses the water, the solar particles/cells and is designed with inlets and outlets
for water and gases. Utilizing a special architecture that integrates membranes for separating the oxygen side from the hydrogen side,
proton transport is increased which is the key to safely increasing solar-to-hydrogen efficiency. On September 26, 2017, we filed a PCT
Application that was later nationalized in the U.S. on March 26, 2019. On April 15, 2024, after a thorough review of our corporate commercialization
plan, we decided to abandon the patent application. While the intellectual property was critical for the designs of the early GEN I and
GEN II inventions, as our process and system designs evolved, we determined that the
