Remember when Cisco sued Apple over the iPhone name?
Cisco sought an injunction against Apple using the name iPhone, which it said was a registered trademark of Cisco acquisition Linksys.
Cisco also aimed its legal guns at Huawei in a dispute over routing software piracy that 3Com also got into the middle of back in 2003.
Cisco — like any big company — has also been the target of assorted lawsuits over the years. These include complaints leveled by a diverse collection of outfits, from the Free Software Foundation to East Carolina University.
