Strategic summary

As of today, May 22, 2026, all claims of US Patent 9,800,633 remain untested by a final PTAB decision. The single pending IPR, IPR2026-00346, initiated by Meta Platforms, Inc., has not yet reached an institution decision, meaning no claims have been canceled or sustained by the PTAB. Therefore, the patent's claims are neither hardened nor narrowed through PTAB trials at this juncture.

The estoppel landscape under § 315(e)(2) is not yet applicable, as no Final Written Decision has been issued. Once an FWD is issued, Meta Platforms, Inc. and its privies would be estopped from raising grounds that were raised or reasonably could have been raised in the IPR concerning the claims subject to the FWD. Currently, all prior-art grounds remain theoretically available to a new defendant. There are no observable patterns of multiple IPRs from the same petitioner or aggressive appeals by the patent owner, given the nascent stage of the sole proceeding.

Recommended next steps

The IPR2026-00346 proceeding is in its early stages. A key milestone to watch for is the institution decision, which will determine if the PTAB agrees to institute a trial on the challenged claims. The statutory deadline for this decision is typically within three months of the patent owner’s preliminary response, or six months from the date of the petition if no preliminary response is filed. The IPR has a statutory 1-year trial deadline from institution. Monitoring the progress of IPR2026-00346 on the USPTO PTAB E2E system is crucial for understanding the evolving validity landscape of US9800633.
