Where a claimed solution:

  • is one of several possible solutions; and

  • there is no special inducement or reason for choosing the claimed solution; and

  • there is a surprising and unexpected advantage in the claimed solution

then the solution is not obvious. The person skilled in the art would not have been "directly led to the invention". "Selections" are discussed in Selection Criteria (however, note Special Inducements; Obvious Selections).
