We are aware of no constraints, intellectual property or otherwise, that would impede or block the use of any proposed assay or model or would block or impede commercial development of AT-1501 for the treatment of ALS. We have worked with outside counsel to do preliminary patent clearance searches and have not identified any patents that will block development or marketing of AT-1501 in the U.S.
