Strategic Summary
The absence of any IPR, PGR, or CBM challenges against U.S. Patent No. 12,239,914 means that all its claims remain valid and untested before the Patent Trial and Appeal Board (PTAB). For a potential defendant, this presents both an opportunity and a risk.
On one hand, the patent is not "hardened" by having survived a previous validity challenge. This leaves the door wide open for a defendant to be the first to file an IPR, with the full universe of prior art and invalidity arguments available. No estoppel under 35 U.S.C. § 315(e)(2) applies, meaning a petitioner would not be barred from raising arguments that could have been raised in a prior proceeding.
On the other hand, the lack of PTAB history provides no intelligence on how the patent owner, Hong Kong Zhan Teng Jiada Technology Ltd, might respond to a validity challenge or how the PTAB might view the claims.
Recommended Next Steps
For a defendant facing a potential infringement assertion of U.S. Patent No. 12,239,914, the key takeaway is that a PTAB challenge is a fully available defensive option.
- No PTAB Activity on File: A comprehensive search of USPTO and public records confirms there have been no inter partes review (IPR), post-grant review (PGR), or covered business method (CBM) proceedings filed against this patent.
- Full Range of Defenses Available: Because no previous PTAB challenges have been initiated, a defendant is not estopped from raising any invalidity grounds based on patents or printed publications that a skilled searcher could reasonably be expected to have found. All claims are potentially vulnerable to a well-crafted petition.
- Consider a Proactive Search: The next logical step for a defendant would be to conduct a thorough prior art search to assess the strength of a potential invalidity case under 35 U.S.C. §§ 102 (anticipation) or 103 (obviousness) for use in a potential IPR petition.
