Strategic summary
As there are no PTAB proceedings on file for US Patent 7502518, all five claims (Claims 1-5) remain untested by AIA trial proceedings. This means the patent has not been subjected to challenges based on prior art in an IPR, PGR, or CBM.
The absence of PTAB activity indicates that the patent has not yet faced validity challenges in this forum. This could mean several things: the patent may not have been heavily asserted, or any challenges to its validity have occurred in district court litigation (which I was unable to find) or through other means.
Recommended next steps
Since no PTAB activity exists for US Patent 7502518, a potential defendant would not face any estoppel limitations under § 315(e)(2) at the PTAB. All prior-art grounds would theoretically be available for a new petition. If a defendant is facing assertion of this patent, they could consider filing an IPR, PGR, or CBM petition to challenge the patent's validity based on prior art.
