I have read on Surachart Opun’s blog that 18.104.22.168 is available, but also that the patchset is now a full installation.
In the past, if you wanted to have 22.214.171.124 or 10.2.0.5, you needed to install both the base version, 126.96.36.199 or 10.2.0.1 and the patchset, 188.8.131.52 or 10.2.0.5. Very often the patchset itself was bigger and took more time than the base database installation.
According to Note 1189783.1, it is now possible to install 184.108.40.206 without having to install both 220.127.116.11 + a patchset.
if you are installing Oracle Database on a system without an existing Oracle Database installation, then you can simply install the release 18.104.22.168 patch set
