Examiner here, in biotech. Besides our internal equivalent of Patent Public Search, Google Patents is where I start. I also use lens.org and ip.com less frequently, and SciFinder when I need to search specific chemicals. STN is for searches prior to allowance when I want to confirm that there really, really isn't any art that teaches the thing I haven't found yet. Source: about 1 year ago
If the patent has been published, it's under "Supplemental Content" in Patent Center. You could also look up the patent on lens.org. Source: over 1 year ago
