The Lexmark Litigation: Why Does Big Pharma Care So Much About Ink Cartridges?

The Federal Circuit will soon hear Lexmark v. Impression Products, a case about ink cartridges. Impression, a foreign buyer, refills spent Lexmark cartridges and resells them in the United States. Impression claims that Lexmark, having sold the cartridges, has exhausted its patent rights, and cannot hold Impression liable for patent infringement. The Federal Circuit will address whether the US patent is exhausted with the sale of the patented product outside the US, write Burcu Kilic and Peter Maybarduk.
