 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**

**enforce its patent rights for that product will be in effect shortened and Kineta’s competitors may obtain approval to market competing products sooner. The resulting reduction of years of revenue from applicable products could be substantial.

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 has sought protection for its intellectual property, such protection can be less extensive than those in the United States. The requirements for patentability may differ in certain countries, particularly developing countries, and the breadth of patent claims allowed can be inconsistent. In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as federal and state laws in the United States. In-licensing patents covering Kineta’s product candidates in all countries throughout the world may similarly be prohibitively expensive, if such opportunities are available at all. And in-licensing or filing, prosecuting and defending patents even in only those jurisdictions in which Kineta develops or commercializes its product candidates may be prohibitively expensive or impractical. Competitors may use Kineta’s and its licensors’ technologies in jurisdictions where Kineta has not obtained patent protection or licensed patents to develop their own products and, further, may export otherwise infringing products to territories where Kineta and its licensors have patent protection, but where enforcement is not as strong as that in the United States or Europe. These products may compete with Kineta’s product candidates, and Kineta or its licensors’ patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.

The laws of some jurisdictions do not protect intellectual property rights to the same extent as the laws or regulations in the United States and Europe, and
