Narrative:

I filed an IFR flight plan from sjc-ZZZ. Sjc tower mentioned prior to takeoff; that there was an extended delay for departure. A VFR departure was discussed with tower as that would reduce the delay in departure. A new VFR clearance was issued; with a 5;000-foot altitude restriction (standard altitude for VFR departures in sjc). After takeoff we departed runway 12R with a standard departure. After contacting; norcal departure on 121.3; we verified our cleared altitude of 5;000 and were radar identified. Norcal then cleared us 'on course and approved climb to our VFR altitude;' which was unusual. I questioned the controller; 'I wanted to confirm; we are cleared to 17;500 and not to stop at 5;000'? The controller confirmed; 'yes you are cleared to 17;500.' this was unusual as I have flown out of sjc for 15 + years and usually the class B airspace is restrictive. I followed the controller's instructions per the aim which states; pilots are to comply with ATC instructions. After handoff we once again confirmed climbing to 17;500. Upon climbing thru 8;800 (800 into the class B airspace) the controller questioned and asked if I had clearance into the class B airspace; I answered; yes it was my understanding we were cleared. He gave me a number to call after landing which I complied. The supervisor said he reviewed the ATC communications and acknowledged that I clearly was cleared to 17;500 and on at least 4 occasions I confirmed this clearance with the various norcal controllers. He said; unless the controller states 'cleared into the class B airspace;' the controller won't necessarily feel a class B clearance was issued; but also acknowledged that I clearly questioned the clearance to 17;500 and I complied with the ATC clearance(s) per the aim. No traffic conflict occurred or any TCAS events. I feel this difference in apparent phraseology; needs to be better stressed in either the aim or other FAA transmittals.
