Even while Cisco Systems is suing Apple for violating its iPhone trademark, an open-source enthusiast is accusing Cisco itself of infringing copyright in the same product.
Cisco has not published the source code for some components of the WIP300 iPhone in accordance with its open-source licensing agreement, said Armijn Hemel, a consultant with Loohuis Consulting and half of the team running the GPL Violations Project, an organization that identifies and publicizes misuse of GPL (GNU General Public License) licenses and takes some violators to court.
