Can I include Abandoned Patent in CV?
I'm assuming you mean abandoned in the sense defined by the USPTO. A patent (application) is abandoned if the application is never completed for some reason and cannot move forward to registration. In that sense an abandoned patent is not a patent, so it would seem to be a mistake to include it as anything other than incomplete and abandoned work. 

Perhaps you can find a way to include the work in another way that is more positive. Did it result in any publications, for example?
