Microsoft announced that they have filed Patent Infringement Action against GPS device maker TomTom.
Microsoft says that they have tried to engage in licensing discussions with TomTom over a year with no success.
Microsoft's Horacio Gutierrez says: "We have an established intellectual property licensing program, and the patents involved in this case, relating to innovations in car navigation technology and other computing functionality, have been licensed by many others.
In situations such as this, when a reasonable business agreement cannot be reached, we have no choice but to pursue legal action to protect our innovations and our partners who license them. Other companies that utilize Microsoft patents have licensed and we are asking TomTom to do the same. TomTom is a highly respected and important company. We remain open to quickly resolving this situation with them through an IP licensing agreement."
