Narrative:
We had B747 traffic pointed out by ATC and an altitude restriction of 1;000 ft below the B747. I advised aircraft in sight and watched it pass to our right with what I thought was enough horizontal separation that I didn't think we would have a wake encounter. After the B747 passed by; we were given a continued climb clearance. Shortly after beginning our climb we struck the wake of the B747 resulting in a sharp jolt and minor pitch and roll diversions. We advised ATC that we had just struck the wake turbulence of the B747 and the controller responded; 'sorry about that'. I fly enough on the tracks to know to offset around heavy aircraft; but since we were on what turned out to be a converging flight path; which wasn't readily apparent until we flew into the other aircraft's wake; we didn't take any wake turbulence precautions. Fortunately it was a positioning flight and no passengers were on board; as the jolt surely would've have caused them some concern.
