Quanta v. LG

Posted by Dirk Avery at 10:44 am under Patent, Supreme Court.

Patent exhaustion is alive and well, even for method patents. The key from the Supreme Court’s slip opinion:

Nothing in this Court’s approach to patent exhaustion supports LGE’s argument that method claims, as a category, are never exhaustible. A patented method may not be sold in the same way as an article or device, but methods nonetheless may be “embodied” in a product, the sale of which exhausts patent rights. The Court has repeatedly found method patents exhausted by the sale of an item embodying the method . . . . These cases rest on solid footing. Eliminating exhaustion for method patents would seriously undermine the exhaustion doctrine, since patentees seeking to avoid exhaustion could simply draft their claims to describe a method rather than an apparatus. On LGE’s theory here, for example, although Intel is authorized to sell a completed computer system that practices the LGE Patents, downstream purchasers could be liable for patent infringement, which would violate the longstanding principle that, when a patented item is “once lawfully made and sold, there is no restriction on [its] use to be implied for the [patentee’s] benefit.”
