In case you are owning different versions of Oracle WebLogic Server, e.g. 10.3.6, 12.1.3, 12.2.1.2 and so on and you are regularly applying the Oracle Critical Patch Updates, you will have to download various different Patches.
Mainly you will have to click through different Websites and My Oracle Support Notes until you can download the required patches.
For this purpose I have developed a handy script, with which you can perform a fully unintended download of the latest Oracle WebLogic Server CPU Patches.
All what you need is:
Instructions
At first generate the required folder structure on your Linux Server:
root@server> cd /
root@server> mkdir -p CPU_TOOL/em_catalog
root@server> mkdir -p CPU_TOOL/archive
root@server> mkdir CPU_PATCHES
Create in the directory CPU_TOOL the following 2 files:
patch_download.ksh (afterwards make it executable chmod +x patch_download.ksh

Download the getMOSPatch.jar from
https://github.com/MarisElsins/getMOSPatch and place it under /CPU_TOOL/getMOSPatch
root@server> mkdir -p /CPU_TOOL/getMOSPatch
root@server> cp /tmp/getMOSPatch.jar /CPU_TOOL/getMOSPatch
Make sure that you have a java 1.6 or higher in your PATH
root@server> which java
/bin/java
root@server> java -version
openjdk version "1.8.0_102"
OpenJDK Runtime Environment (build 1.8.0_102-b14)
OpenJDK 64-Bit Server VM (build 25.102-b14, mixed mode)
How does it work?
The trick behind the unintended CPU download is really simple, I am using the em_catalog.zip provided by My Oracle Support, which is used by Oracle Cloud Control for the so called Offline Patching (see MOS Note
https://support.oracle.com/epmos/faces/DocContentDisplay?id=1931891.1)
In the patch_download.ksh script within the function DownloadEMCatalog() I am downloading the latest version of the em_catalog.zip, place it in the subdirectory /CPU_TOOL/em_catalog, unzip the file.
In the function DownloadPatches() I am using grep to identify the latest available CPU Patches for various WebLogic Server Releases within the file /CPU_TOOL/em_catalog/patch_recommendations.xml and through Maris Elsins' getMOSPatch I am downloading unintended the identified Patches, place them in the directory /CPU_PATCHES/WLS/<VersionNumber>/YYYY_Q[1|2|3|4] and creating a symlink on the latest CPU Patch to actual.
Get your Patches
To download the latest available patches, simply execute following commands:
root@server> cd /CPU_TOOL
root@server> ./patch_download.ksh -i mos.properties

Now you will find under the directory /CPU_PATCHES/WLS<VersionNumber>/YYYY_Q[1|2|3|4] the latest available CPU Patch for your Oracle WebLogic Server.
You can easily change in the mos.properties configuration file the target location for the CPU Patches to e.g. a mounted NAS drive, which you can attach to your WebLogic hosts, so that the patches are immediately available on your hosts for WebLogic Server.
