[The United States announced the chip Act "guardrail" rules!] The Office of the Chip Program of the US Department of Commerce issued a statement on September 22, saying that the US Department of Commerce issued the final rule on the implementation of the national security protection measures of the Chip and Science Act on the same day. The rule details two core provisions of the act: The first provision prohibits chip Fund recipients from expanding semiconductor material production capacity in other relevant countries for ten years. The second provision restricts recipients from conducting certain joint research or technology licensing activities with relevant foreign entities. The Chip and Science Act is part of President Joe Biden's Invest in America agenda to unleash a manufacturing and innovation boom that will drive U.S. competitiveness and strengthen economic and national security.
