Item 3. Legal Proceedings.
From time to time, we may become involved in litigation or other legal proceedings relating to claims arising from the ordinary course of business. There are currently no claims or actions pending against us that, in the opinion of our management, are likely to have a material adverse effect on our business, results of operations, financial condition or growth prospects. There is one ongoing ex parte re-examination for one of our patents.

On August 1, 2018, a third party requested ex parte re-examination of certain claims of U.S. Patent No. 9,511,092, which relates generally to chimeric receptor complexes that bind certain specific natural killer cell ligands and methods of using natural killer cells. U.S. Patent No. 9,511,092 does not relate to our current product candidates but may relate to future product candidates or alternative technologies. This first re-examination by the USPTO is currently pending. On August 2, 2019, a third party requested an ex parte re-examination on the remaining claims of U.S. Patent No. 9,511,092, with the USPTO subsequently issuing a Reexamination Certificate confirming patentability of the claims in an amended form on August 18, 2020 . Although we plan to vigorously protect our intellectual property rights, as with all legal proceedings, there can be no guarantee as to the outcome, and, regardless of the merits of third-party challenges, such proceedings are time-consuming and costly. As a result of such re-examinations, our rights under the relevant patents could be narrowed or lost, and in the course of such proceedings, we may incur substantial costs and the time and attention of our management may be diverted from the development and commercialization of our product candidates.
