Here's a concise summary of US Patent 12102368:
US Patent 12102368
- Title: Bone positioning guide
- Assignee: Treace Medical Concepts Inc
- Inventors: W. Bret Smith, Paul Dayton, Sean F. Scanlan, F. Barry Bays, Carlos Eduardo Gil, John T. Treace, Robert D. Santrock, Daniel J. Hatch, Joe W. Ferguson
- Filing Date: April 5, 2024 (for application US18/627,609)
- Issue Date: October 1, 2024
- Abstract: A bone positioning guide may include a main body member, a shaft, and a bone engagement member. The shaft is movably connected to the main body member and has the bone engagement member rotatably coupled to its distal end. The bone engagement member has a surface configured to engage a bone. The main body member also includes a tip opposite the bone engagement member for engaging a second bone. In use, the bone engagement member may be positioned in contact with a medial side of a first metatarsal while the tip is positioned in contact with a lateral side of a different metatarsal, such as a second metatarsal. The shaft can then be moved to advance the bone engagement member toward the tip, causing realignment of the first metatarsal.

Proceedings overview
There is one AIA trial proceeding on file for US Patent 12102368. This proceeding is currently active and pending an institution decision. Given the early stage of the proceeding, no claims have been invalidated or sustained, and the patent's claims remain untested by a final written decision. The defensive posture for a defendant is that one IPR has been filed and is in its early stages, meaning the patent's validity is currently being challenged, but no determination has yet been made.
IPR2026-00194 — Paragon 28, Inc. v. Treace Medical Concepts Inc.
- Type: Inter Partes Review
- Filed: 2026-01-05
- Status: Pending. The proceeding is ongoing and awaiting an institution decision from the PTAB.
- Judge panel: Information regarding the specific Administrative Patent Judges (APJ) assigned to this panel is not publicly available at this early stage of the proceeding.
- Petition grounds: The specific claims challenged, the prior art cited, and the statutory bases (§ 102 for anticipation / § 103 for obviousness) for the petition are not publicly detailed in the provided data. This information would typically be found in the filed petition.
- Institution decision: Not yet issued. As of 2026-05-28, the PTAB has not yet decided whether to institute an IPR. The statutory deadline for an institution decision is typically six months from the filing date of the petition, which would be around 2026-07-05.
- Final Written Decision: Not applicable; a Final Written Decision has not been issued as the case is still pending institution.
- Settlement / termination: Not applicable; the proceeding is active and has not been settled or terminated.
- Appeal: Not applicable; no Final Written Decision has been issued to appeal.
- Defensive value: This proceeding indicates that at least one competitor, Paragon 28, Inc., believes there are valid grounds to challenge the patentability of claims in US12102368. While the IPR is still pending, it represents an active challenge to the patent's validity. Should institution be granted, it will highlight specific claims and prior art that the PTAB believes have a reasonable likelihood of success.
Strategic summary
US Patent 12102368 is currently subject to a single Inter Partes Review, IPR2026-00194, filed by Paragon 28, Inc. on 2026-01-05. As of today, 2026-05-28, this proceeding is in its early stages and is awaiting a decision on institution. This means that currently, all claims of US12102368 are legally considered valid and have not been canceled or sustained by the PTAB. The specific claims being challenged and the prior art asserted by Paragon 28, Inc. are not detailed in the provided information, but would typically target claims related to the "bone positioning guide" described in the patent (e.g., claims outlining the main body member, shaft, bone engagement member, and tip, or the methods of positioning bones).
The estoppel landscape under § 315(e)(2) is not yet applicable as no Final Written Decision has been rendered. If the IPR is instituted and proceeds to a Final Written Decision, Paragon 28, Inc. (and its privies) would be estopped from raising invalidity grounds that were raised or reasonably could have been raised during the IPR with respect to claims found patentable. However, until then, all prior-art grounds remain available to other potential challengers or defendants. The filing of this IPR by Paragon 28, Inc. suggests that this patent may be part of an ongoing competitive landscape or litigation, and the petitioner is a direct market player.
Recommended next steps
For a defendant facing assertion of US patent 12102368:
- Monitor IPR2026-00194 closely: The institution decision for IPR2026-00194 is expected around 2026-07-05. This decision will be a critical milestone. If institution is denied, it suggests the PTAB found the petition grounds unconvincing, which strengthens the patent. If instituted, the specific claims challenged and the PTAB's reasoning will provide valuable insight into potential weaknesses of the patent. You can monitor the progress of this case on the USPTO PTAB E2E portal.
- Review the petition: Obtain and review the petition filed by Paragon 28, Inc. to understand the specific claims being challenged, the prior art cited, and the invalidity arguments presented. This information is crucial for assessing the strength of the challenge and informing your own defensive strategy.
- Anticipate trial stages: If IPR2026-00194 is instituted, be aware of upcoming trial stages, including potential discovery, expert testimony, and the oral hearing. A Final Written Decision would then be due within one year of institution.
- Consider your own PTAB strategy: Depending on the strength of your own prior art and invalidity arguments, you may consider filing your own IPR. The outcome of IPR2026-00194 could influence the scope and strategy of any subsequent petition you might file.

NPE / troll-pattern signals
- Shell-entity transfer — not present. The patent remains with the original operating company, Treace Medical Concepts Inc.
- Known asserter in the chain — not present. Treace Medical Concepts Inc is an operating company, not a known NPE.
- Repeat correspondent across the chain — unclear. While Google Patents indicates an assignment from inventors to the assignee, without the USPTO Assignment Center record details, the correspondent cannot be identified or checked for recurrence.
- Cascading transfers — not present. There are no recorded transfers in the USPTO Assignment Center.
- Pre-litigation transfer — unclear. The patent was issued on October 1, 2024, and litigation (IPR2026-00194, 1:25-cv-00592) was filed subsequently. While the Google Patents record shows an assignment from inventors to the assignee on September 23, 2024, the exact date of the first infringement suit is not precisely given beyond the year "2025" for the Delaware case, making it difficult to definitively assess if this transfer was "pre-litigation" (i.e., within 6 months of a suit).
- Bankruptcy fire-sale — not present. Treace Medical Concepts Inc is an active, operating company.
- Privateering — not present. The patent remains with the operating company.
- Defensive aggregator (anti-NPE) — not present. The patent is held by an operating company and is involved in litigation.
Verdict
Operating-company assertion. The patent is currently assigned to Treace Medical Concepts Inc, an operating company that commercializes products embodying the claims. While litigation is pending (IPR2026-00194 and 1:25-cv-00592), there is no evidence of a transfer to a shell entity or known NPE.

Obviousness
Combinations of prior art that suggest the claimed invention would have been obvious under 35 U.S.C. § 103.
An analysis of the obviousness of US patent 12102368 under 35 U.S.C. § 103 cannot be fully performed with the information provided. To conduct a proper obviousness analysis, the following are required:
- Full Text of the Claims of US12102368: The independent claims, in their entirety, are necessary to determine the scope of the invention and compare them against prior art. Only an abstract summary of the claims is available in the provided "Patent summary" section.
- Specific Prior Art References (Documents): The "Prior art" section of the provided patent text lists "metatarsal," "bone," "guide," "fixation," and "positioning guide" as "Prior art keywords" and "2015-07-14" as a "Prior art date." These are keywords and a date, not specific patent or non-patent literature documents that can be combined for an obviousness argument.
While the "Legal status" section mentions that US12102368B2 claims priority from U.S. patent application Ser. No. 14/981,335, which issued as U.S. Pat. No. 9,622,805 (US9622805B2), this earlier application/patent is typically considered a parent or continuity application. Subject matter disclosed in a parent application that supports the claims of a continuation application generally does not serve as prior art against the continuation application for obviousness purposes under 35 U.S.C. § 103, provided the claims of US12102368 are fully supported by the disclosure of US9622805B2. Without additional specific prior art documents, identifying combinations and motivations for a person having ordinary skill in the art to combine them is not possible.
Therefore, without the complete claims of US12102368 and a list of specific prior art documents (e.g., patents or publications cited during prosecution, or other relevant prior art), a comprehensive obviousness analysis under 35 U.S.C. § 103, including identifying combinations of references and motivations to combine them, cannot be completed.
