Patents & Licenses

Many BDSC stocks contain patented components. Some are listed below, but this list is not exhaustive. Most patent owners permit unrestricted use of their materials for nonprofit research only but some require licenses for any use. We provide notification of licensing requirements when stipulated by distribution agreements, but lack of notification should not be construed as a lack of licensing requirements for for-profit research. It is the recipient's responsibility to obtain any necessary licenses from the patent holder for commercial work with these stocks.

We will provide contact information for recipients of specific stocks with patented components to patent holders requiring use licenses. This information will provided only upon prior arrangement with the patent holder and only when recipients are notified of the licensing requirement during the ordering process.

The U.S. Patent and Trademark Office (PTO) offers a searchable full-text database of U.S. patents issued since January 1, 1976. Use the PTO search page to find many patents related to Drosophila. FlyBase also includes Drosophila patents in its references, but only the citation is available from FlyBase.
