You just need to last one; they are cumulative.
The language you are puzzled by is required by Tivoli in our Release 
Notes.  While users may call our test fixes and FixPacks, "patches", they 
are not in the eyes of Tivoli architects.  "Patches" is a Tivoli technical 
term for a certain kind of packaged maintenance, usually applied by the 
Framework.  NetView does not produce patches for its code, so none are 
superseded.  NetView did produce Framework patches a long time ago to 
allow installation under the Framework, but no new ones have been produced 
since.
