The second answer to this question suggest patents.google.com as the best way to search for reexamined patents. However, if I search for the classification 'F25B' and 'reexamination', the results haven't actually been reexamined, they just have the word in the text. Is there a better way to search for reexamined patents by classification?

USPTO's PatFT provides functionality for this. In particular, the re-examination certificate (REEX, where REEX=YES refers to a certificate of re-examination being present) and current CPC classification class (CPCL) are probably be relevant.
The query REEX/YES and CPCL/F25B seems to provide what you want.

Clicking through some of the patents at that link, APT/2 seems to be reissue rather than reexamination, or am I missing something? I can't figure out what other code is reexamination by guessing and checking or googling. – ericksonla Feb 14 '17 at 23:11

@ericksonla Absolutely right, I embarrassingly misread the question. I have updated my answer now. – Maca Feb 15 '17 at 0:54
