Narrative:
The important items are: 1) expect revised clearance because of different runway 11 vs 29. 2) right turn to 290 degrees, keep it tight to the airport. 3) no 6 mi restriction. 4) clearance to 10000'. Our initial ATC clearance at oak was 'cleared to bur skyline 1 departure, fellows transition, cross the oak 6 DME fix at or below 2000, maintain 10000, expect further clearance to FL330 10 mins after departure.' a frequency for departure and a squawk were issued and we were instructed, 'do not exceed 250 KTS until advised.' when we asked for a taxi clearance at oak, ground responded 'wind 110 at 11, will you be able to use 29?' we responded, 'we'd rather have 11.' we were issued several clrncs to taxi due to traffic to runway 11 at taxiway 7 and told to expect a new departure clearance from ground control. Having switched to tower and while holding short of runway 11 we told tower that we were advised to expect a new clearance from ground control and hadn't received it. We asked if we should return to ground. Reply: 'no, you'll get your departure clearance on the runway.' while clearing us into position tower cleared us to 'make an immediate right turn after takeoff to 290 degrees, keep it close to the airport.' while in position the captain asked tower, 'do we have any restrictions, like the 6 mi restriction?' the controller hesitated, then answered 'no.' we were cleared to take off, made our right turn and were instructed to contact bay departure. We checked in with bay: 'bay departure, air carrier X climbing to 10000.' reply: 'air carrier X, maintain 2000, you have traffic climbing through 2200 off sfo.' copilot: 'roger, air carrier X out first officer 2600' descending to 2000, where is that traffic?' bay: 'air carrier X, I'm holding him at 3000, expedite climb to 13000.' later a different controller asked us if we had received a 2000' climb restriction after takeoff.

Title: ACR X HAD LESS THAN STANDARD SEPARATION FROM ACR Y. SYSTEM ERROR.
Narrative: THE IMPORTANT ITEMS ARE: 1) EXPECT REVISED CLRNC BECAUSE OF DIFFERENT RWY 11 VS 29. 2) RIGHT TURN TO 290 DEGS, KEEP IT TIGHT TO THE ARPT. 3) NO 6 MI RESTRICTION. 4) CLRNC TO 10000'. OUR INITIAL ATC CLRNC AT OAK WAS 'CLRED TO BUR SKYLINE 1 DEP, FELLOWS TRANSITION, CROSS THE OAK 6 DME FIX AT OR BELOW 2000, MAINTAIN 10000, EXPECT FURTHER CLRNC TO FL330 10 MINS AFTER DEP.' A FREQ FOR DEP AND A SQUAWK WERE ISSUED AND WE WERE INSTRUCTED, 'DO NOT EXCEED 250 KTS UNTIL ADVISED.' WHEN WE ASKED FOR A TAXI CLRNC AT OAK, GND RESPONDED 'WIND 110 AT 11, WILL YOU BE ABLE TO USE 29?' WE RESPONDED, 'WE'D RATHER HAVE 11.' WE WERE ISSUED SEVERAL CLRNCS TO TAXI DUE TO TFC TO RWY 11 AT TXWY 7 AND TOLD TO EXPECT A NEW DEP CLRNC FROM GND CTL. HAVING SWITCHED TO TWR AND WHILE HOLDING SHORT OF RWY 11 WE TOLD TWR THAT WE WERE ADVISED TO EXPECT A NEW CLRNC FROM GND CTL AND HADN'T RECEIVED IT. WE ASKED IF WE SHOULD RETURN TO GND. REPLY: 'NO, YOU'LL GET YOUR DEP CLRNC ON THE RWY.' WHILE CLRING US INTO POS TWR CLRED US TO 'MAKE AN IMMEDIATE RIGHT TURN AFTER TKOF TO 290 DEGS, KEEP IT CLOSE TO THE ARPT.' WHILE IN POS THE CAPT ASKED TWR, 'DO WE HAVE ANY RESTRICTIONS, LIKE THE 6 MI RESTRICTION?' THE CTLR HESITATED, THEN ANSWERED 'NO.' WE WERE CLRED TO TAKE OFF, MADE OUR RIGHT TURN AND WERE INSTRUCTED TO CONTACT BAY DEP. WE CHKED IN WITH BAY: 'BAY DEP, ACR X CLBING TO 10000.' REPLY: 'ACR X, MAINTAIN 2000, YOU HAVE TFC CLBING THROUGH 2200 OFF SFO.' COPLT: 'ROGER, ACR X OUT FO 2600' DSNDING TO 2000, WHERE IS THAT TFC?' BAY: 'ACR X, I'M HOLDING HIM AT 3000, EXPEDITE CLB TO 13000.' LATER A DIFFERENT CTLR ASKED US IF WE HAD RECEIVED A 2000' CLB RESTRICTION AFTER TKOF.
