11.1.0.7 is the latest patchset for 11gR1
September 21st, 2009
You will get CPU and even PSU (Patch Set Updates are proactive cumulative patches comprised of recommended bug fixes that are released on a regular and predictable schedule)
But no more patchset. This the first time I see a release with only 1 pachset.
Well, if you use Linux, you can go to 11gR2. Otherwise you may better stick to 10.2.0.4 for a few more months
