This lick is from the song Satch Boogie, by Joe Satriani from his 1987 release Surfing with the Alien.

The lick starts with a half step bend in D mixolydian pattern 2, and then works its way down the neck, through patterns 1,5 and 4. The end of the lick utilizes the open d string in between the fretted notes as it climbs down. This works because the open D is in the key of the solo.
