Recommended next steps
Since no PTAB activity exists for US Patent 8,266,124, the absence of such proceedings is a notable signal. Well-asserted patents often attract IPRs, especially if they are deemed valuable or are used in litigation. For a potential defendant facing assertion of this patent, it implies that the patent claims have not undergone the scrutiny of an AIA trial.
If facing an assertion of US8266124, a defendant should consider a comprehensive prior art search to evaluate the patentability of the asserted claims. If strong prior art is found, filing an IPR petition could be a viable defense strategy, as there is no existing PTAB record that would indicate hardened claims or a history of surviving such challenges.
