The expiration dates of the issued U.S. patents involved in our current business range from 2022 to 2026. The expiration dates of the issued European patents involved in our current business range from 2022 to 2024. For some of the earlier dates, we plan to seek extensions of the patent life, and believe we have reasonable grounds for doing so.
