Strategic summary
All claims of US12158289 are currently untested by PTAB proceedings. This means that a defendant facing assertion of this patent would have a full range of prior-art grounds available for an IPR petition, subject to the statutory time bars (e.g., one year from being served with a complaint alleging infringement). The absence of PTAB activity can sometimes signal that a patent is relatively new, has not yet been widely asserted, or that potential challengers have not yet identified strong grounds for invalidity in an AIA trial.
Recommended next steps
Since no PTAB activity exists for US12158289, a defendant receiving an assertion based on this patent would need to:
- Conduct a thorough prior art search to identify potential grounds for invalidity under 35 U.S.C. §§ 102 and/or 103.
- Evaluate the claims of the patent against any identified prior art to determine the viability of filing an IPR petition.
- Be mindful of the one-year statutory bar for filing an IPR petition if served with a complaint for infringement.
