The firm's corporate and R&D offices are located at the headquarters in Lexington, Kentucky, United States. Lexmark has offices throughout North and South America, Asia, Africa and Europe. The company has more than 13,000 employees worldwide. Lexmark is a Fortune 500 company and had $5.22 billion in revenues in 2005. In addition to manufacturing hardware under their own name, Lexmark also does third party development of printers for other major companies, such as Dell.
A court victory in 2005 was handed to Lexmark in the case of ACRA v. Lexmark. This case states that Lexmark can enforce the "single use only" policy written on the side of Lexmark printer cartridge boxes sold to certain large customers at a discount, with the understanding that the customers will return the cartridges to Lexmark after using them. This means that these customers can face lawsuits if they breach the agreements, and do not return the cartridges. Also in 2005, Lexmark suffered a legal defeat in the case of Lexmark Int'l v. Static Control Components, when the US Supreme Court rejected Lexmark's petition for a writ of certiorari, thereby rejecting their attempt to have the Court hear their case.
