In a drastic reversal, the Supreme Court in Life Tech. v. Promega Corp. decided to limit the scope of infringement under 35 U.S.C. 271(f)(1). 271(f)(1) provides for infringement for exporting "all or a substantial portion of the components of a patented invention". The Court ruled that the "supply of a single component of a multicomponent invention for manufacture abroad does not give rise to 271(f)(1) liability".
