[Article/U.S.] Research on Exceptions to Infringement of U.S. Process Patents (Intellectual Property Management, Vol. 74, No. 8, 2024)
35 U.S.C. § 271(g)

Exceptions: (1) materially changed by subsequent processes; (2) becomes a trivial and nonessential component of another product.

Translator’s notes (editorial)
The source has an apparent typographical phrase meaning “nonessential”; rendered as nonessential in the statutory-exception context.
