RPC:HW 3-23-11:In re Hall similar case
Massachusetts Institute of Technology v. Harman Intern. Industries, Inc. US District Court of Massachusetts Sept. 9 2008
MIT had a graduate student working on a "Back Seat Drvier Feature" of a GPS in cars, which is a voice activated system for inputing information by the passengers into the device. Harman claimed the grad student's thesis was filed before the critical date, and the experimentation methods using 50 unpaid drivers without confidentiality agreements make the partent in valid.
It was ruled that the Public Publication in the form of the the graduate students thesis was valid under 102b by filing after the critical date, however the test trials without confidentiality made the patent invalid under public use.
