The Advancing American Innovation Act amends federal trade law to tighten rules for patent infringement cases brought before the U.S. International Trade Commission. The bill refocuses the commission's resources on protecting genuine domestic industries by requiring complainants to demonstrate they have made substantial investments in developing or licensing technology, and prevents companies from relying solely on licensees' activities to qualify as a U.S. industry. The legislation also adds transparency requirements for patent cases by mandating that complainants disclose the identity of third-party litigation funders, any funding agreements, and related details within ten days of establishing a funding relationship or when the case begins. Additionally, the bill allows the commission to expedite decisions on certain issues within one hundred days and requires it to consider broader economic impacts, public health effects, and consumer interests when deciding whether to block imports or issue cease-and-desist orders. The changes take effect immediately for complaints filed after the bill becomes law, with no specific funding authorized.
