It's too hard a question to generalize.
A paid settlement is cash in the bank. Pretty easy to divide by # of shares and see how much that instantly adds value to the company.
Things get tricky when you have to analyze stuff like:
- Does this settlement then create precedent for other settlements with other companies? Or is it a one-time payout?
- Does the settlement validate some kind of technology or business practice which was, until then, discounted by the market?
- Has the company been handicapped by lack of capital but can now fund its expansion plans?
- If there is some kind of ongoing revenue derived from winning a settlement, how long does it last? i.e., a patent becomes public domain after a number of years.
