Strategic summary

Currently, the patent US11338511 is subject to one active Inter Partes Review, IPR2025-01242, filed by 3D Systems Corporation et al. The PTAB has instituted a trial in this proceeding, meaning that the Board found a reasonable likelihood that at least one challenged claim is unpatentable. Specific details regarding which claims are challenged, the prior art cited, and the grounds for institution are not publicly available in the provided context or readily accessible via initial search. Therefore, it is currently unknown which claims of 11338511 are specifically being tested in this IPR.

The estoppel landscape is not fully formed yet, as no Final Written Decision has been issued. Once a Final Written Decision is issued, § 315(e)(2) will bar the petitioner (and their privies) from asserting in other proceedings that a claim is invalid on any ground that the petitioner raised or reasonably could have raised during the IPR. Without knowing the specific grounds raised in the petition for IPR2025-01242, it is impossible to specify which prior-art grounds would be estopped for future defendants. The involvement of "3D Systems Corporation et al." as a petitioner suggests a potential industry competitor or a group defending against the patent.

Recommended next steps

• As IPR2025-01242 is ongoing and in the "Trial Instituted" phase, a defendant should closely track the progress of this proceeding. The PTAB has a statutory deadline of one year from institution to issue a Final Written Decision. The institution date is not explicitly provided in the prompt, but given the filing date of 2025-07-18 and the last modified date of 2026-05-13, the institution decision likely occurred several months after filing. The Final Written Decision is expected by mid-2026 to early 2027, assuming a standard timeline.
