Recommended next steps
Since no PTAB activity exists for US Patent 9305450, a potential defendant facing assertion of this patent has several avenues:
- Evaluate prior art: Conduct a thorough prior art search to identify potential grounds for an IPR petition against the patent's claims. The absence of previous PTAB challenges suggests that the patent has not undergone this scrutiny, and new prior art could be effective.
- Monitor for future proceedings: Stay vigilant for any newly filed IPR, PGR, or CBM petitions against US9305450. The filing of such a petition by another party could provide valuable insight and potentially influence defensive strategies.
- Consider filing an IPR: If strong prior art is found, filing an IPR petition could be a viable strategy to challenge the validity of the asserted claims. This would be a first-mover advantage, setting the precedent for subsequent challenges or defenses.
