When Microsoft first sued TomTom for patent violations in TomTom's Linux-powered navigation devices, I wasn't sure how much of a fight TomTom would put up. Legally TomTom was between a rock and a hard place. You can't use restricted-use patents in GPLed software.

Can you believe it? This is so great!! Morrison & Foerster are representing TomTom in a new patent infringement lawsuit TomTom has just filed against Microsoft! I love covering their cases. Patent law is usually soooo boring to me, but these guys will keep me awake, and no doubt if I pay attention, I'll learn a lot.

Microsoft filed suit against TomTom today, alleging that the in-car navigation company's devices violate eight of its patents -- including three that relate to TomTom's implementation of the Linux kernel.

TomTom and Microsoft have settled the patent litigation. Here's TechFlash's coverage. According to the Microsoft press release, TomTom will remove functionality regarding the FAT patents within two years, which is no big deal, frankly, and in the meantime, they are covered "in a manner that is fully compliant with TomTom's obligations under the General Public License Version 2 (GPLv2)"

Rob Enderle stands up to defend Microsoft, whom he assumes must have valid patents being asserted in Microsoft's patent litigation lawsuit against TomTom. He therefore wants TomTom to just pay up, and he'd like Linux folks to quit being a drama queen about it all. So, I guess that means Enderle still doesn't understand the GPL? You think? Linux folks are not going to be moving on.

This is exactly what we were afraid of. Last month, when Microsoft sued Dutch GPS-maker TomTom on the principle that parts of Linux -- which form the guts of TomTom's device -- violate Microsoft's patents, we hoped for a quick settlement.

Here's the complaint filed by Microsoft against TomTom, NV and TomTom, Inc., alleging patent infringement, as PDF and as text. We'll be setting up a Timeline page for it after TomTom files its answer.

Despite Microsoft assurances that a patent lawsuit against GPS navigation company TomTom is not targeting the overall Linux community, open-source leaders said on Thursday that the legal action is antagonistic toward the movement.

Microsoft Corp. was sued by Dutch navigation-device maker TomTom NV, which claims the world’s largest software maker infringes four of its patents used for automobile navigation.
The suit comes less than a month after Microsoft filed a complaint with the U.S. International Trade Commission in Washington seeking to block some of TomTom’s U.S. imports.
