Intellectual Property
Our original license with Battelle National Laboratory (the “Battelle License”) reached its end of life in 2022. During the past several years, we have expanded our proprietary knowledge, as well as our trademark and patent protection, in anticipation of the Battelle License reaching the end of its term.
Our RadioGel trademark protection is in 17 countries. We have expanded our trademark protection from RadioGel to now include IsoPet. We obtained the International Certificate of Registration for ISOPET, which is the first step to file in several countries.
We filed for trademark protection for the term Precision Radionuclide TherapyTM. We believe this term will be increasingly important.

The Company received the Patent Cooperation Treaty (“PCT”) International Search Report on our patent application (No.1811.191). Seven of our claims were immediately ruled as having novelty, inventive step and industrial applicability. This gives us the basis to extend for many years the patent protection for our proprietary Yttrium-90 phosphate particles utilized in Isopet® and Radiogel™.
Our patent team filed our particle patent in more than ten patent offices that collectively cover 63 countries throughout the world. We filed a continuation-in-part applications number 1774054 in the United States of America (“USA”, or “U.S.”) to expand the claims on our particle patent. The U.S. Patent office recently gave us the Notice of Allowance for our patent to produce our yttrium phosphate microparticles, U.S. Patent Application Serial No: 16-459,466. We also filed an amendment to correct the wording on our claims at make them consistent with the USE claims. Ref: 4207-0005; European Patent Application NO. 20 834 229.5; VIVOS INC; Our Ref: FS/53791.
We filed a hydrogel utility patent in the USA (16309:17/943,311) and internationally (16389:PCT/US22/4374) based on the last 18 months of development work to optimize our hydrogel component. These include reducing the polymer production time and increasing the output by a factor of three. We have also further reduced the level of trace contaminants to be well below the FDA guidelines.
We filed a provisional patent (Serial Number 63436562) to protect our innovative improvements in our shipping container, our vial shield, our syringe shield, and our Peltier chiller. Our objectives were to reduce shipping costs, decrease radiation exposure, and enhance sterility. These devices will be preferentially used at Mayo Clinics for human clinical studies at and our IsoPet regional treatment centers. We filed a utility patent in our fourth quarter of 2023 for this therapy support equipment.
We anticipate that Precision Radionuclide Therapy will become increasingly important in the future and expand to other isotope and other indications for use. Therefore, we filed an alternate particle utility patent (Serial number 18/152,137). The Company will focus its near-term effort on the Yttrium-90 therapy, which we believe is the best beta emitter; however, we leveraged our hydrogel utility patent to incorporate other promising isotopes and compounds for a range of future applications. This includes gamma and alpha particle emitters.
