Office-equipment manufacturer Pitney Bowes has filed a lawsuit against companies including Apple for violating a printer patent.
Pitney Bowes claims a number of companies have violated patent 4,386,272, a technology used to antialias printed characters.
The patent was filed in 1983 and expired in 2000. Connecticut-based Pitney Bowes claims it is entitled to royalties on any laser printer using this patented technology during those years.
Pitney Bowes settled a similar lawsuit last year against Hewlett-Packard, for $400 million.
Companies named in the lawsuit include Apple, Matsushita Electric of America, Panasonic Personal Computer, NEC Technologies, Samsung Electronics America, Samsung Electronics and Oak Technology.
