I haven't come across a way to do this ... Only reverting to previous version.

The only method, is to rollback, to the previous version.

Reboot the ESXi 5.1 host server, and at the BOOT prompt, enter Recovery Mode e.g. Shift-R

this will reboot the older version, without the patch, however we have found sometimes, there is no recovery mode.

So you would have to re-install ESXi 5.1.

What is the issue with the patch ?

Thank you all, This is the first time I installed the patch in vm. I wanted to make sure that i can remove/go back to previous ver in case if there is any adverse effect after applying the patches.
I know now that i can only go back yo previous ver.
