“The authorized sale of an article that substantially embodies a patent exhausts the patent holder's rights and prevents the patent holder from invoking patent law to control postsale use of the article. Here, LGE licensed Intel to practice any of its patents and to sell products practicing those patents. Intel's microprocessors and chipsets substantially embodied the LGE Patents because they had no reasonable noninfringing use and included all the inventive aspects of the patented methods. Nothing in the License Agreement limited Intel's ability to sell its products practicing the LGE Patents. Intel's authorized sale to Quanta thus took its products outside the scope of the patent monopoly, and as a result, LGE can no longer assert its patent rights against Quanta.” Quanta Computer v. LG Electronics, 128 S.Ct. 2109, 2122 (2008)
“The declared purpose of the patent law is to promote the progress of science and the useful arts by granting to the inventor a limited monopoly, the exercise of which will enable him to secure the financial rewards for his invention. Constitution of the United States, Art. I, § 8, Cl. 8; 35 U.S.C. §§ 31, 40. The full extent of the monopoly is the patentee's ‘exclusive right to make, use, and vend the invention or discovery.’ The patentee may surrender his monopoly in whole by the sale of his patent or in part by the sale of an article embodying the invention. His monopoly remains so long as he retains the ownership of the patented article. But sale of it exhausts the monopoly in that article and the patentee may not thereafter, by virtue of his patent, control the use or disposition of the article. Bloomer v. McQuewan, 14 How. 539, 549-50; Adams v. Burke, 17 Wall. 453; Hobbie v. Jennison, 149 U.S. 355. Hence the patentee cannot control the resale price of patented articles which he has sold, either by resort to an infringement suit, or, consistently with the Sherman Act (unless the Miller-Tydings Act applies), by stipulating for price maintenance by his vendees.
