This patent estate is a valuable asset to us and our shareholders, as it protects our inventions in RNA-based drug discovery and our drugs, and encourages revenue-generating partnerships. We maintain our competitive advantage in the field of antisense technology by protecting our core platform technology and by creating multiple layers of patent protections for each of our drugs.
While the principal purpose of our intellectual property is to protect our products and those of our partners, our intellectual property is also a strategic asset that we exploit to generate near-term revenues and that we expect will also provide us with revenue in the future. To date, we have generated over $400 million from our intellectual property sale and licensing program that helps support our internal drug discovery and development programs.
