A petition for inter partes review may be filed after the later of:
(i) Nine months after the grant of a patent or issuance of a reissue of a patent; or
(ii) If a post-grant review is instituted, the date of the termination of that post-grant review.

Requirements for Inter Partes Review
A petition for inter partes review may be considered only if the following conditions are met:
Timing of Determination by Office to Institute Inter Partes Review
The Office must determine whether to institute an inter partes review within three months after:
(i) Receiving a preliminary response to the petition; or
(ii) If no such preliminary response is filed, the last date on which such response may be filed.
Burden of Proof for Inter Partes Review
Petitioner must prove by preponderance of the evidence unpatentability.
Timing of Post-Grant Review
Must occur within nine months after the date of the grant of the patent, or of the issuance of a reissue patent.
Estoppel for Post-Grant and Inter Partes Review
Same for both, namely, estopped on any ground that the petitioner “raised or reasonably could have raised during that review.”
WARNING: As with inter partes review, watch out for ITC. There will be estoppel at ITC, but the ITC is not a Federal Court, meaning that statements made at the ITC by the patent owner cannot be submitted as a third-party issuance submission.
Can you appeal a decision by the director on whether to initiate a post-grant proceeding?
No. Decision on whether to institute is final and not appealable.
Who can file for an Ex Parte Reexamination?
Anyone, including patent owner.
