This story is big news in the little world of general aviation. RunwayFinder was an excellent free product, well loved, and a lot of pilots are angry about it being bullied offline. RunwayFinder says they don't infringe. It seems likely to me, between the prior art, the obviousness of the patent, and the specificity of the patent claims (including language about using "housekeeping frames"). But they lack the means to defend themselves. I blogged some more analysis at http://www.somebits.com/weblog/aviation/flightprep-patent-7640098.html http://www.somebits.com/weblog/aviation/flightprep-patent-76... FlightPrep tried to go after the deep pockets in the industry, too, Jeppesen. Jepp's apparently blown them off: http://www.aopa.org/flightplanning/articles/2010/101214AOPA_Flight_Planner_does_not_infringe_on_patent.html http://www.aopa.org/flightplanning/articles/2010/101214AOPA_...
