The EPM patch situation is ever changing. I've trawled through the patch search pages and provided direct links to all the latest patches for EPM versions 11.1.2.2 and 11.1.2.3

Note that for the latter, Oracle have made a welcome change of approach by releasing one major (1.8G) patch set update that covers most of the Foundation and Applications and tagged under 'Hyperion Shared Services' as the product. There are still seperate patches for the Essbase related components and DRM.
