Impression Products, Inc. v. Lexmark International Inc.
In Impression Products, Inc. v. Lexmark International Inc., printer company Lexmark sold printer cartridges with restrictions on refilling and resale. Impression Products acquired used Lexmark ink cartridges and then refilled and resold them, sparking a lawsuit from Lexmark claiming infringement. The Federal Circuit decided in Lexmark’s favor, ruling that a customer’s use of a product can be “restricted” by the patent owner with something as simple as a notice on disposable packaging.
In an amicus brief filed in the Supreme Court, EFF argues that “conditional sales” like the ones attempted by Lexmark cannot impose arbitrary conditions on a customer’s use of a product. The Federal Circuit’s incorrect ruling to the contrary goes against the doctrine of “patent exhaustion,” which says that once a patent owner sells a product, it cannot later claim the product’s use or sale is infringing.
