Trade secret in reexam

Question on Trade secret, Proprietary, protective order materials. It seems the answer is easily found in MPEP 724.

724 Trade Secret, Proprietary, and Protective Order Materials

[...]

That wherever possible, trade secret law and patent laws should be administered in such manner

that the former will not deter an inventor from seeking the benefit of the latter, because,

the public is most benefited by the early disclosure of the invention in consideration of the

patent grant. If a patent applicant is unwilling to pursue his right to a patent at the risk

of certain loss of trade secret protection, the two systems will conflict, the public will be

deprived of knowledge of the invention in many cases, and inventors will be reluctant to bring

unsettled legal questions of significant current interest . . . for resolution.

The choices I remember were "information important for patentability will become part of

records accessible to the public unless petition is granted to expunge" & "information

found important will stay in the sealed envelope & never will become available to the public"
