Claim Drafting Exhaustion: Potential Implications of Claim Format
In the landmark case
Quanta Computer,
Inc.
v.
LG Electronics,
Inc., 553 U.S. 617 (2008), the Supreme Court considered whether and to what extent the authorized sale of an unpatented component may exhaust patent rights covering a method performed by the component when integrated into a product.

Id. at 638.
