# §1.525. Order for ex parte reexamination.

- (a) If a substantial new question of patentability is found pursuant to [§ 1.515](/cfr/37/1.515.md) or [§ 1.520](/cfr/37/1.520.md), the determination will include an order for ex parte reexamination of the patent for resolution of the question. If the order for ex parte reexamination resulted from a petition pursuant to [§ 1.515(c)](/cfr/37/1.515.md?p=c), the ex parte reexamination will ordinarily be conducted by an examiner other than the examiner responsible for the initial determination under [§ 1.515(a)](/cfr/37/1.515.md?p=a).
- (b) The notice published in the Official Gazette under [§ 1.11(c)](/cfr/37/1.11.md?p=c) will be considered to be constructive notice and ex parte reexamination will proceed.
