PTAB challenges
AIA trial proceedings at the USPTO Patent Trial and Appeal Board — IPR, PGR, and CBM. Petitioners, judge panels, claim-level invalidation outcomes from Final Written Decisions, and Federal Circuit appeals. The single most important defensive datapoint after litigation history.
Proceedings overview
There are no AIA trial proceedings (Inter Partes Review, Post-Grant Review, or Covered Business Method reviews) on file for US Patent 0220967. This is because "US Patent 0220967" does not correspond to a granted US patent, but rather to a patent application publication, US 2004/0220967 A1. AIA trials are conducted exclusively on granted patents, not on patent applications. Therefore, there are no claims that have been invalidated or sustained through PTAB review for this number, and the defensive posture remains unaffected by PTAB activity.
No PTAB proceedings found for US Patent 0220967
As confirmed by the USPTO Open Data Portal, there are currently no AIA trial proceedings (IPR, PGR, or CBM) on file for US Patent 0220967. This is consistent with the earlier analysis which determined that "US Patent 0220967" is not an issued patent, but rather refers to the patent application publication US 2004/0220967 A1. PTAB trials, such as IPRs, PGRs, and CBMs, are only applicable to granted US patents.
Strategic summary
Since US Patent 0220967 is a patent application publication (US 2004/0220967 A1) and not a granted patent, it is not eligible for AIA trial proceedings before the Patent Trial and Appeal Board. Consequently, no claims from this document have been challenged, canceled, or sustained through IPR, PGR, or CBM processes. The patent has not been narrowed, nor have its claims been "hardened" by surviving PTAB challenges.
The absence of PTAB activity means there is no estoppel landscape from AIA trials to consider. All prior-art grounds, whether raised in other contexts or not, would theoretically remain available if this application were ever to issue as a patent and then be challenged.
Recommended next steps
Given that US Patent 0220967 is an application publication and not a granted patent, the typical PTAB-related next steps for a defendant facing assertion do not apply. If a demand letter or lawsuit cites "US patent 0220967," it is likely referring to the application publication, which cannot be directly asserted for infringement. Infringement claims can only be brought on granted patent claims.
Therefore, the recommended next step for any entity receiving an assertion based on "US patent 0220967" would be to confirm the actual legal status of the document being asserted. If the patent number cited is truly an application publication, then there is no granted patent to infringe, and no PTAB proceeding can be initiated against it.
