Interesting IP litigation story from Kotaku:
The May 30 launch of an “Oregon Trail” expansion pack in the popular Facebook game Frontierville has caught notice of the company holding the copyright to the edutainment classic, and it has sued to put a stop to the plans of Frontierville maker Zynga.
The lawsuit, filed by The Learning Company in federal court in Massachusetts, alleges that Zynga cut a trailer for its “Oregon Trail” missions (above) that highlights similarities between them and the The Oregon Trail notably “setting up a wagon, provisioning, hunting, fording rivers, and helping others.” For the record, the trailer refers not to dysentery but “the Rocky Mountain Scoots.”
[Yes, the lawsuit is going on in Massachusetts but I couldn't avoid mentioning it here.]
