The U.S. Supreme Court has rejected Lexmarks petition on toner cartridge fight. If you remember Lexmark was trying and had for a period stopped a competitor from selling a chip that enabled consumers to buy cheaper toner cartridges. The mfgr of the chip designs chips for various printers on the market. Lexmark who’s business model was suggested to be built on inexpensive printers and over priced toner cartridges got a taste of economics today, that sends a clear message to competitors. Competition is good and when you try to stick it to a customer then you are going to pay one way or the other. [SiliconValley.com]
