Cholestosome Technology

The Cholestosome Patent Family Uniquely achieves High Oral Bioavailability of Proteins, Peptides and Nucleotides. Simultaneously we load Proteins, Peptides and Nucleic Acids into Body Cells, without need to attach a virus. Cholestosomes enter cells by facilitated diffusion, so there is no endosomal degradation of our encapsulated material. Issued patents are listed here with links to download

Patent Status Update

We continue to expand the reach of these patents, as they are filed globally using the PCT process. China was issued in 2019. Approvals are anticipated in 2020 in Japan, Europe, Australia, Brazil, Mexico and Israel. We are actively licensing the processes and manufacturing methods to partners with molecules in need of intracellular delivery.

Patent History

The original Invention of the Cholestosome was made by Professor Mary McCourt in 2006, and filed in conjunction with Niagara University. In 2012 we discovered the power in the chylomicron pathway, thereby enabling unprecedented oral bioavailability and intracellular delivery. Cholestosomes deliver 2X-100X intracellularly, without need for either a viral vector or the need for an endosomal step. This meant that we could deliver a molecule intact into the cytoplasm for diffusion anywhere in the cell.

Starting in 2013, these inventions were filed by the inventors directly. All Patents in this Series are Assigned to TheraSyn Sensors Inc, and there are revenue sharing agreements in place with Niagara University and the University at Buffalo.
