I joined a new company and they are using AIX. So I have just a few patches but NOWHERE on the internet could I find how to download the patches. The machines are not connected to the internet.
If you're talking about patching the operating system, or a range of related products (such as PowerVM, PowerHA, etc.) then you usually start at IBM Fix Central.
There's not much to be said in terms of an answer, other than go there, fill in the drop downs with your product information, and the site builds a list of packages to download.
For AIX, you would normally get a TL (technology level) or SP (service pack) set of files, whack them on the server, and use the relevant OS commands to do an apply.
This link https://www-304.ibm.com/support/docview.wss?uid=isg3T1012517 has the latest patch cycles for AIX.

basically, IBM do no longer ship single fixes, except for Emergency Fixes to correct really high pervasive errors and Security Fixes to fill security holes.
Instead, they deliver Technology Level packages to contain major fixes/revisions/enhancements and, between TLs , there are Service Packages to contain just fixes (in most cases).
Emergency/Security fixes as well as TL/SP packages can all be downloaded from IBM Fix Central: http://www-933.ibm.com/support/fixcentral/
There is also a tool called SUMA (Service Update Management Assistant) to automatically search for fix packages and to download them at regular intervals.
There are several nice papers dealing with the IBM AIX Service Strategy.
These are the central documents on our topic: http://public.dhe.ibm.com/common/ssi/ecm/en/pow03060usen/POW03060USEN.PDF https://www14.software.ibm.com/webapp/set2/sas/f/best/aix_service_strategy_v3.pdf
And this is for SUMA: http://www-03.ibm.com/systems/resources/systems_p_os_aix_whitepapers_suma.pdf
Here is another "Best Practices" paper containing information on how to use the various service tools: http://rdsrc.us/qrhP6d
The actual process of applying service to AIX is rather simple with SMIT.
Once you downloaded a package (or a single Security fix) just run
You can the choose between installing new software components ("Install Software"), applying a TL or SP package ("Update Installed Software to Latest Level (Update All)") or to install single fixes (" Update Software by Fix").
The following menus all require specifying the directory you downloaded the software to, and several additional options which you can mostly leave on their defaults, except for the option "ACCEPT new license agreements?" where you must always specify "yes" ("no" is the default).
The update process will then run automatically, and at the end you will be informed whether a reboot at a time of your choice will be required (a reboot is always required after applying a TL or SP).
The starting point for installing Emergency Fixes is slightly different, you will reach the appropriate menus with "smitty emgr".
