When a managed server is down, the transactions in progress during failure of that anaged server will be lost.
However; users sessions will be re-established and migrated to another managed server in the cluster.

As for the near-zero downtime patching, what I recommend you is to use the online patching.
Online patching can even be used for FMW..

I mean patch the patch filesystems and then take them into production during cutover..

EBSapps.env run
adop phase=prepare
. EBSapps.env patch
Change the directory where the bsu.sh resides using a command like cd $FMW_ HOME/utils/bsu.    
Execute the bsu script using the command . /bsu.sh
adop phase=finalize
adop phase=cutover
adop phase=cleanup

AS for your rolling patching related question, yeah, if the patch in question is a Zero Downtime Patch, then my answer is yes.

A Zero Downtime Patch is identifiable by the instructions in the patch's README file. The README should say something like : "This patch has been marked as eligible for Zero Downtime Patching. The type of Zero Downtime Patching supported by this patch is FMW_ROLLING_ORACLE_HOME"
