Supreme Court of the United States, FOMBPR v. CPI (2023)
“ Our precedent thus conveys a consistent message: If a defendant enjoys sovereign immunity (which we are assuming the Board does) , abrogation requires an “unequivocal declaration” from Congress. Dellmuth v. Muth, 491 U. S. 223, 232 (1989) . The Court has found that standard met in only two situations. The first is when a statute says in so many words that it is stripping immunity from a sovereign entity. Congress, for example, has provided that States “shall not be immune,” under any “doctrine of sovereign immunity, from suit in Federal court” for patent or copyright infringement. ”
