Proceedings overview
There are no AIA trial proceedings on file for US Patent 7788272 according to the USPTO Open Data Portal as of the most recent ingest, and no additional proceedings were identified through web searches. This means the patent has not been subjected to IPR, PGR, or CBM trials at the PTAB.
Strategic summary
Given the absence of any AIA trial proceedings, all claims (Claims 1-19) of US7788272 remain untested at the PTAB. None of the claims have been canceled or sustained through an IPR, PGR, or CBM Final Written Decision.
The estoppel landscape is entirely open; a defendant facing assertion of this patent would not be barred by § 315(e)(2) from raising any prior-art grounds, as no PTAB trial has concluded. There is no pattern of filings by a specific petitioner, no aggressive PTAB appeals by the patent owner, and no involvement of defensive aggregators like Unified Patents.
Recommended next steps
Since no PTAB activity exists for US Patent 7788272, the absence of such proceedings suggests that the patent has not been extensively challenged at the PTAB. For a potential defendant, this means:
- No existing invalidity findings: There are no PTAB-determined invalidity grounds to leverage in defense.
- Open field for challenge: All prior art grounds are available for a potential IPR or PGR filing, assuming the statutory requirements for such a petition are met (e.g., filing deadlines, prior art type).
- Expired Status: It is important to note that US7788272 expired due to fee-related issues on October 3, 2022. This significantly impacts its assertability, as an expired patent cannot be infringed after its expiration date. Any assertion would be limited to alleged infringement occurring before October 3, 2022.
- Consideration of filing a new petition: While the patent is expired, a defendant facing claims of past infringement might still consider an IPR filing if they believe there are strong invalidity arguments and if the timing and cost-benefit analysis support it. However, the expired status might reduce the incentive to invest in a PTAB challenge, as the patent cannot be asserted going forward.
