, over 10 foreign patents issued in such jurisdictions as China, Israel, Korea, Singapore, and others, and over five foreign patent applications pending in such jurisdictions as Europe, Canada, and Brazil. Not accounting for any patent term adjustment or extensions or terminal disclaimers, and assuming that all applicable annuity and/or maintenance fees are paid timely, the issued patents, and, if granted, the pending patent applications in this family, are expected to expire in 2037. We also own a patent family with claims directed to formulations of rademikibart that includes a pending U.S. patent application, at least five foreign patents issued in such jurisdictions as China, Taiwan, and South Africa, and over 15 foreign patent applications pending in such jurisdictions as Europe, Canada, Brazil, and others.

In the U.S., the term of a patent that covers an FDA-approved drug may also be eligible for a patent term extension of up to five years under the Hatch-Waxman Act, which is designed to compensate for the patent term lost during the FDA regulatory review process. The length of the patent term extension is calculated based on the length of time it takes for regulatory review.
