Nct controller described a possible wake turbulence remnant event between an oak departure and a sfo arrival; the reporter indicating that either identifying remnant tools be made available for controllers or that wake separation requirements be further clarified in procedural documents.

Narrative:
A B737 departed oak on the skyline SID. He was given radar contact and an unrestricted climb to 100; then a heading of 260. Traffic was issued which was a sfo arrival a B777 that would be going down the bay. The B737 reported the traffic in sight and was given a wake turbulence advisory. The B737 was then turned to a heading of 200. The B777 was turned down the bay and had begun their descent to 60. The B737 was then turned to a heading of 180. At some point in the B737's climb he flew through the 'wake remnants' of the B777. Recommendation; we either need the tools that will allow us to follow the wake remnants trail or operating behind a heavy jet means following it or on the same general heading not crossing behind on a perpendicular course.
