What is the effect of a final court decision on an inter partes reexamination?

A final court decision can have significant effects on an inter partes reexamination:

• If a final court decision holds claims invalid, those claims will typically be withdrawn from the reexamination.
• If all claims being examined are held invalid, the reexamination may be terminated.
• A final court decision upholding validity may lead to termination of the reexamination for those claims, but only if certain conditions are met under 35 U.S.C. 317(b).

The MPEP states: Upon the issuance of a final holding of invalidity or unenforceability, the claims held invalid or unenforceable will be withdrawn from consideration in the reexamination if the Office is notified of the final court decision.
