I asked if a Markman ruling carries over into the later rounds of lawsuits or does it have to be revisited with each group of subsequent filings.

Here is the response:

It is our understanding that the Markman process results in definitive rulings by a Federal Court regarding the meaning of specific claim terms within a patent (or patents). Once a Federal Court has issued its Markman rulings, it becomes difficult to vary from those meanings and in most cases there are no further claim constructions undertaken. Generally, the original rulings carry over to subsequent defendants.
