Apple sued over printers it no longer makes

The Register: “Apple has been sued for allegedly infringing a single patent in products it hasn’t
produced or sold for over three years.

The plaintiff, US-based mail handling and document processing specialist Pitney
Bowes, claims its intellectual property – the so-called ‘272 patent’ – is integral to
Apple’s LaserWriter laser printer, and was filed before Apple developed its machine.
Pitney Bowes’ patent covers “variable dot printing patent which enhances the
resolution of laser printing”, according to the company.”
