Which types of patterns are you asking about? (sketch patterns (in sketches), assembly component patterns (in assemblies), part feature patterns (in parts)
Your image looks like it might be a DrawingSketch using the patterning tools available within the sketch environment, but I it might also be a view of either an assembly or a multi-body part.
If it is a sketch, it's fairly easy to copy just the original geometry set again, even after it has been used within an earlier rectangular pattern (using sketch tools), so I'm guessing you mean one of the other methods. Can you clarify a little further, or maybe supply a test file with detailed instructions of what you are hoping to accomplish?
