Since the 19th of April there is a new patch set available for Weblogic servers – Patch 22505404: WLS PATCH SET UPDATE 12.1.3.0.160419. This patchset has included 116 fixes and is a generic one. The patch is listed in the Enterprise Manager 13c as recommended. OPatch has no to be updated. This patch is not an online patch, you have to shut down your running EM13c server.
This blog post describes the apply of the Weblogic patch set update in an Enterprise Manager 13c environment running on a Oracle Linux server.
Prepare Patch Set Update on EM13c Server
The patch file has to be extracted. I have copied to file to a stage directory /u00/app/oracle/stage on the EM13c server.
[oracle@solothurn stage]$ unzip p22505404_121300_Generic.zip
Set ORACLE_HOME
Set the ORACLE_HOME variable to the directory where the Oracle Enterprise Manager 13c is located. In my example the EM13 is installed in directory /u00/app/oracle/product/em13cr1.
[oracle@solothurn ~]$ export ORACLE_HOME=/u00/app/oracle/product/em13cr1
Stop running Oracle Enterprise Manager 13c
[oracle@solothurn stage]$ $ORACLE_HOME/bin/emctl stop oms -all Oracle Enterprise Manager Cloud Control 13c Release 1 Copyright (c) 1996, 2015 Oracle Corporation. All rights reserved.

Summary
Patching of the underlying Weblogic component has the same importance like patching the other components like databases and agents. Since Weblogic 12c is used for the Enteprise Manager, patching can be done with the DBA well known OPatch tool which is very easy and good documented.
