 commercialized. As a result, Kineta’s owned and licensed patent portfolio may not provide Kineta with sufficient rights to exclude others from commercializing products similar or identical to Kineta’s.

If Kineta does not obtain patent term extension in the United States under the Drug Price Competition and Patent Term Restoration Act of 1984 (the “Hatch-Waxman Act”) and in foreign countries under similar legislation, thereby potentially extending the term of marketing exclusivity for its product candidates, Kineta’s business may be harmed.

In the United States, a patent that covers an FDA-approved drug or biologic may be eligible for a term extension designed to restore the period of the patent term that is lost during the premarket regulatory review process conducted by the FDA. Depending upon the timing, duration and conditions of FDA marketing approval of Kineta’s product candidates, one or more of Kineta’s U.S. patents may be eligible for limited patent term extension under the Hatch-Waxman Act, which permits a patent term extension of up to five years for a patent covering an approved product as compensation for effective patent term lost during product development and the FDA regulatory review process. A patent term extension cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval, and only claims covering such approved drug product, a method for using it or a method for manufacturing it may be extended. In Europe, Kineta’s product candidates may be eligible for term extensions based on similar legislation. In either jurisdiction, however, Kineta may not receive an extension if it fails to apply within applicable deadlines, fails to apply prior to expiration of relevant patents or otherwise fails to satisfy applicable requirements. Even if Kineta is granted such extension, the duration of such extension may be less than Kineta’s request. If Kineta is unable to obtain a patent term extension, or if the term of any such extension is less than Kineta’s request, the period during which Kineta can**

Kineta enjoys only limited geographical protection with respect to certain patents and Kineta may not be able to protect its intellectual property rights throughout the world.

Filing, prosecuting and defending patents covering Kineta’s product candidates in all countries throughout the world would be prohibitively expensive, and even in countries where Kineta
