Recommended next steps
Since no PTAB activity exists for US Patent 9,203,972, the recommended next steps for a defendant facing assertion of this patent would be:
- Conduct a thorough prior art search: While the patent's original prosecution involved cited prior art, a new, comprehensive search could uncover additional references not previously considered, which might form the basis for a strong invalidity defense, either in district court or a potential IPR.
- Evaluate IPR potential: Assess the strength of potential obviousness or anticipation arguments against the claims based on newly identified or re-evaluated prior art. Given the lack of prior PTAB challenges, this route is fully open.
- Monitor for future PTAB filings: Stay vigilant for any new IPR, PGR, or CBM petitions filed against US 9,203,972 by other parties, as such filings could impact the patent's strength and provide insights into effective invalidity arguments.
- Engage in licensing negotiations or district court defense: The absence of PTAB challenges means that the patent's claims are presumed valid and have not been "hardened" or "softened" by a PTAB decision. Any defense would currently focus on arguments related to non-infringement or invalidity in a district court setting, or through direct negotiation.
