US 10028740

I'll verify the bibliographic data and check for 2026 CAFC activity before summarizing.

Let me verify the docket numbers and confirm whether the 2026 CAFC appeals actually involve this patent.

Let me check the second 2026 appeal (24-1753) and whether the '740 patent remained live in the Globus case.

Verification performed

I ran targeted searches for the literal identifier 10,028,740 / US10028740B2 against Google Patents (full text), PubChem patent records, Justia, Unified Patents' litigation/PTAB portal, the PTAB docket, CAFC/CourtListener dockets, and the Federal Circuit's own opinion PDFs. All identifiers below are reproduced as returned; I am not correcting any of them. Where sources disagree (e.g., filing/grant dates), I flag it rather than resolve it silently.

Bibliographic summary — US 10,028,740 B2

Priority chain (as recited in the patent's own cross-reference paragraph): Continuation of 12/957,776 (now US 9,888,918), which is a continuation-in-part of 12/471,340 (US 8,734,516), CIP of 12/054,335 (US 7,972,363), CIP of 11/842,855 (US 7,942,903), CIP of 11/536,815 (US 7,846,188), which traces to 11/208,644 (US 7,704,279) and provisional 60/670,231 (filed 2005-04-12); 12/957,776 also claims benefit of provisional 61/265,752 (2009-12-01).

Abstract (verbatim): "A horizontal-transvertebral curvilinear nail-screw (HTCN) including a body portion having a first end and a second end, wherein the first end is opposed to the second end; and a head at the first end of the body portion, wherein the body portion has a predetermined curvilinear shape and includes a pointed tip at the second end of the body portion, and a method of surgically implanting universal horizontal-transvertebral curvilinear nail-screws (HTCN) into a plurality of adjacent vertebrae."

Plain-language overview of the independent claims

Claim 1 — the apparatus

A spinal fusion implant built from three pieces working together:

1. A first curvilinear nail-screw that goes into a first vertebral body along a curved path that does not go through the pedicles. It runs from a proximal end (with a head) to a distal end (with a pointed bone-penetrating tip). Along its distal section it carries "first means for engaging a first cancellous core" — i.e., a functional (means-plus-function) recitation of whatever grips the spongy inner bone. The curved path is specified as a single continuous arc.
2. A second curvilinear nail-screw — identical in structure and function, but for a second vertebral body, also on a single continuous arc and also pedicle-avoiding.
3. A connecting support structure with a first hole and a second hole. Each hole receives one of the two nail-screws, so the structure holds the two screws in a fixed relationship to each other while each screw extends into its own vertebral body without penetrating pedicles.

Analyst note: The two "means for engaging a cancellous core" limitations are drafted in means-plus-function form, which would ordinarily invoke 35 U.S.C. §112(f). Dependent claims 3 (fish-hooks), 4 (threads), and 5 (ridges) supply corresponding structure, suggesting the drafter contemplated that construction.

Claim 17 — the method

The surgical counterpart:

1. Implant the first curvilinear nail-screw into a first vertebral body along a curved, pedicle-avoiding trajectory, single continuous arc. When implanted, the head sits outside the vertebral body and the distal portion (with the cancellous-engaging means) sits inside the cancellous core.
2. Implant the second curvilinear nail-screw into a second vertebral body on the same terms.
3. Connect the two screws via the connecting support structure so that each screw extends into its own vertebral body without penetrating pedicles.

Dependent-claim themes (for context)

• Retention/attachment: rotatable connectors (claim 2), caps on the heads (claim 12).
• Bone-engagement structure: radially arranged fish-hooks (3, 20), threads (4, 21), smooth shank plus ridges (5).
• Connecting structure architecture: multiple separate components/links joined directly (6–7); a bar (8); support positioned exterior to the vertebral bodies (13); screws sharing a centerline axis with their holes (14); connection made at curved portions of the screws (15); screws curved all the way from proximal to distal end including the portion joined to the support (16).
• Approach/geometry: lateral (9, 22), posterior (10), anterior (11, 23); each screw traverses no more than 50% of its vertebral body (18); no traversal of an intervertebral disk (19).

Litigation and PTAB history — with an important correction

PTAB — IPR2020-01309, Globus Medical, Inc. v. Moskowitz Family LLC, US 10,028,740 B2. Globus challenged claims 1, 3, 6, 8, 11, 15–18, and 20. The Board denied institution under 35 U.S.C. §314(a) (Paper 7, dated 2021-02-05), finding no reasonable likelihood of prevailing. Fish & Richardson's client alert confirms this was the eighth and final denial among eight Globus IPR petitions, covering US 8,353,913; 9,889,022; 10,028,740; 10,251,643; 10,307,268; and 10,478,319.

District court. The '740 patent was asserted in Moskowitz Family LLC v. Globus Medical Inc., W.D. Tex. No. 6:19-cv-00672 (filed 2019-11-20), transferred on 2020-07-02 to the E.D. Pa. as No. 2:20-cv-03271.

CAFC 2026 dockets — no '740 involvement found. This is the key caveat to your request. The Google Patents family page lists two CAFC cases, but neither one turns on US 10,028,740:

• No. 24-1696 — Moskowitz Family LLC v. Globus Medical, Inc., decided 2026-09-11 (precedential; Judge Prost, with Judges Schall and Stoll). The asserted/appealed patents were US 8,353,913, US 9,889,022, and US 10,478,319 (claims 1 and 10 of the '913; claim 47 of the '022; claim 1 of the '319). The court affirmed summary judgment of noninfringement, the construction of "universal," and denial of JMOL. The '740 patent is not among them.
• No. 24-1753 — Globus's cross-appeal. Voluntarily dismissed under Fed. R. App. P. 42(b) by joint stipulation (2025-04-21); dismissal order and mandate issued 2025-04-24. Also not directed to the '740 patent.

So: I found no 2026 CAFC docket, order, or opinion that specifically names US 10,028,740. The CAFC and Texas/W.D. Tex. litigation links appearing on the Google Patents page for US10028740 are family-level litigation entries (the Moskowitz portfolio was litigated together), not a statement that the '740 patent was itself on appeal.

Also noted but not this patent: separate, newer Medtronic proceedings exist against other Moskowitz patents in 2026 — e.g., IPR2026-00124 (US 11,096,797) and IPR2026-00217, plus Moskowitz Family, LLC v. Medtronic, Inc., D. Minn. No. 0:25-cv-00769. Those do not involve 10,028,740, and I mention them only to rule them out.

Family context (continuations of '740)

US 15/862,016 gave rise to: US 10,258,329 (from 16/042,163), US 2019/0328384 (from 16/384,232, abandoned), US 11,918,207 (from 17/180,021, listed Active), and US 2024/0277335 (from 18/592,947). Notably, the '329 continuation's claim set differs materially from the '740 set — one published version of that continuation recites "curvilinear spinal fixation device" rather than "curvilinear nail-screw," and adds limitations about the connecting support surrounding the proximal ends and heads being larger than the holes.

Confidence and uncertainties

• High confidence (corroborated by Google Patents full text, PubChem, and Justia, and used as authoritative per your instruction): title, patent/application numbers, inventors, assignee, issue date 2018-07-24, filing 2018-01-04, claim text, abstract, priority chain, and the IPR2020-01309 denial.
• Flagged discrepancy: Unified Patents' portal returns a 2005-04-11 priority date, a 2018-01-03 application date, a 2018-07-23 grant date, and a 2025-08-22 expiration — each one day off from Google Patents/PubChem/Justia. These are almost certainly time-zone or data-normalization artifacts, but I cannot confirm which is correct without the USPTO PatentCenter file wrapper, which I could not open in this session.
• Explicitly uncertain: whether the '740 patent was among the Moskowitz patents dismissed without prejudice from the E.D. Pa. case after the December 2023 verdict (secondary commentary mentions five patents dismissed without prejudice and lists '022, '913, '643, '367, and '386 — not '740, but I could not retrieve the dismissal order itself). I therefore cannot state the current posture of the '740 patent in district court with confidence.
• My own analysis, not a source statement: the §112(f) characterization of the "means for engaging" limitations is my technical inference from the claim language and from the dependent claims supplying structure.

Let me dig into the specific district court and Federal Circuit cases.

Let me research the appellate cases and any other defendants (e.g., Medtronic).

Litigation Involving U.S. Patent No. 10,028,740 ("Spinal fusion implant with curvilinear nail-screws")

Bottom line: U.S. Patent No. 10,028,740 (the "'740 patent") has been asserted in one confirmed patent-infringement action — Moskowitz Family LLC v. Globus Medical, Inc. — which was litigated in the Western District of Texas, transferred to the Eastern District of Pennsylvania, and affirmed on appeal by the Federal Circuit. The '740 patent was also the subject of a Globus-filed IPR that was not instituted. There is also evidence of a more recent Moskowitz action against Medtronic that names the '740 patent, but I could not fully confirm that case's docket details (see caveats below).

1. Moskowitz Family LLC v. Globus Medical, Inc. — District Court (W.D. Tex. → E.D. Pa.)

Court (as filed): [U.S. District Court for the Western District of Texas, Waco Division](/courts/western-district-of-texas-waco)
Case No.: 6:19-cv-00672-ADA
Judge: Alan D. Albright
Filed: November 20, 2019
Terminated in W.D. Tex.: July 2, 2020 (transferred)

Court (transferred): U.S. District Court for the Eastern District of Pennsylvania, Philadelphia Division
Case No.: 2:20-cv-03271-MSG
Judge: Chief Judge Mitchell S. Goldberg
Transferred/docketed in E.D. Pa.: July 6, 2020
Terminated: August 13, 2024

• Plaintiff: Moskowitz Family LLC

• Defendant: Globus Medical, Inc.

• The '740 patent's role: The '740 patent was one of eight asserted patents in the original complaint. The W.D. Tex. transfer order lists the asserted patents as U.S. Patent Nos. 8,353,913; 9,889,022; 10,028,740; 10,076,376; 10,307,268; 10,241,643; 10,376,386; and 10,478,319 (transfer order, 6:19-cv-00672-ADA). Globus's June 17, 2020 opening claim-construction brief addressed several '740-specific terms ("curvilinear nail screw," "first [and second] means for engaging a cancellous core," "connecting support structure," "radially arranged fish-hooks," "bar") (claim construction brief).

• Outcome / status:

  • In December 2023, following an eight-day jury trial in E.D. Pa., the jury returned a complete defense verdict of non-infringement; the district court had earlier granted Globus summary judgment of non-infringement as to the '913 and '022 patents, and denied Moskowitz's post-trial JMOL motion (Susman Godfrey).
  • The appeal ultimately addressed only the '913, '022, and '319 patents — the '740 patent was not part of the Federal Circuit's September 2026 decision. A 2024 E.D. Pa. opinion (Doc. 399) did address a '740-patent dispute over the term "single continuous arc," concerning whether the head of the accused products lies on the arc (Justia, Doc. 399). Based on the available record, the '740 patent did not proceed to the jury trial, and I could not independently confirm its exact final disposition (e.g., whether it was voluntarily dropped, dismissed, or resolved on summary judgment).

2. PTAB — Globus Medical, Inc. v. Moskowitz Family LLC, IPR2020-01309

• Forum: USPTO Patent Trial and Appeal Board
• Petitioner: Globus Medical, Inc. | Patent Owner: Moskowitz Family LLC
• Filing date: July 21, 2020
• Patent challenged: U.S. 10,028,740 ("'740 patent")
• Claims challenged: 1, 3, 6, 8, 11, 15, 16, 17, 18, 20
• Panel: Meredith C. Petravick (writing), Neil T. Powell, James J. Mayberry
• Institution decision: February 5, 2021
• Outcome: Institution DENIED (challenged claims not reviewed on the merits; the '740 patent was not invalidated in this proceeding).

This is consistent with the Google Patents family page, which lists "PTAB case IPR2020-01309 filed (Not Instituted – Merits)" for this patent.

3. Federal Circuit — Moskowitz Family LLC v. Globus Medical, Inc.

• Court: U.S. Court of Appeals for the Federal Circuit
• Appeal No.: 2024-1696 (Moskowitz's appeal); Cross-Appeal No.: 2024-1753 (filed April 30, 2024; consolidated with 24-1696)
• Parties: Moskowitz Family LLC (appellant/plaintiff) v. Globus Medical, Inc. (appellee/defendant)
• Panel: Prost, Schall, Stoll, JJ.
• Oral argument: May 4, 2026
• Decision: September 11, 2026 (precedential) — AFFIRMED in full.
  • Held that the "universal" claim preambles in the '913 and '022 patents are limiting, and affirmed summary judgment of non-infringement on those patents.
  • Held that substantial evidence supported the jury's non-infringement verdict on the '319 patent, and affirmed the denial of JMOL.
  • The '740 patent was not among the patents decided.

Sources: CAFC docket page · Fed Circuit Blog · IPWatchdog · National Law Review

Note on dates: You listed the current date as April 26, 2026, but the Federal Circuit's precedential decision in this matter issued September 11, 2026 (and the case's oral argument audio was posted May 4, 2026). I am reporting the dates exactly as the sources state them.

4. Possible additional action — Medtronic

A 2025 PTAB petition and its exhibits indicate a separate Moskowitz Family LLC action against Medtronic, Inc. (and related "Medtronic Defendants") in which U.S. 10,028,740 is among eight asserted patents. The exhibit quotes the complaint describing spinal-fusion patents (including the '740 "curvilinear nail screw") and describes Minnesota contacts, suggesting a District of Minnesota filing.

• Forum (apparent): U.S. District Court for the District of Minnesota (not fully confirmed)
• Related PTAB proceeding: IPR2026-00121, Petitioner Medtronic, Inc. (exhibit dated November 10, 2025)
• Filing date / case number: Not confirmed from the sources I retrieved.

Because I could not verify the plaintiff/defendant caption, jurisdiction, case number, or filing date for this matter, I am flagging it as unconfirmed rather than reporting it as a confirmed case. If you need it fully verified, PACER (D. Minn.) and the PTAB docket for IPR2026-00121 should be checked directly.

Summary table

Important caveats

1. Literal patent number: All results above are for U.S. 10,028,740 specifically (a "Spinal fusion implant with curvilinear nail-screws," app. no. 15/862,016, granted July 24, 2018). The related family members (e.g., 9,888,918; 10,258,329) are different patents and were not counted here.
2. The '740 patent is not one of the three patents the Federal Circuit decided in September 2026; that appeal covered the '913, '022, and '319 patents. I could not fully confirm the '740 patent's terminal disposition in the E.D. Pa. case.
3. Litigation databases can lag. The Google Patents family page's "litigation" entries for this patent list the W.D. Tex. case, the E.D. Pa. case, the two Federal Circuit appeals, and the IPR — but those listings are sourced from third-party datasets and should be verified against PACER for any filing/status you intend to rely on.

I'll start by pulling the canonical proceeding list and then verify with web search.

Let me dig into the specific proceeding details.

Let me get the substantive reasoning behind the denial and check for any other proceedings.

Proceedings overview

Total AIA trials on US 10028740: 1 — institution denied (0 active, 0 claims canceled, 0 claims sustained, 0 settled). The only proceeding ever filed against this patent, IPR2020-01309 (Globus Medical v. Moskowitz Family), was filed 2020-07-21 and denied institution on the merits on 2021-02-05 — the Board found no reasonable likelihood on any challenged claim. That gives a defendant an unusual posture: the patent has never been tested in a trial, yet a well-funded, sophisticated competitor (Globus) attacked it and failed at the threshold. All 23 claims of the '740 patent remain live and uncanceled. Be aware of a data discrepancy before you rely on any clearance opinion built on "no PTAB record": the structured ODP block in this file reports no AIA trials, but the Board's own public decision (Paper 7) exists and the patent's Google Patents family record itself flags "PTAB case IPR2020-01309 filed (Not Instituted – Merits)." Treat the ODP "empty" result as an indexing gap, not as evidence of no activity.

⚠️ Sourcing note on the structured block. The "PTAB proceedings on file" block states ODP returns no AIA trial proceedings for this patent. That is contradicted by (a) the patent text you supplied, which lists IPR2020-01309, and (b) the public institution decision. I am reporting the proceeding below on the strength of the document itself rather than the ODP field.

IPR2020-01309 — Globus Medical, Inc. v. Moskowitz Family LLC

• Type: Inter Partes Review (35 U.S.C. §§ 311–319)

• Filed: 2020-07-21 (Petition served on Patent Owner's counsel of record, Fish & Richardson P.C., same date; Exhibits 1001–1031)

• Patent: U.S. Patent No. 10,028,740 B2 ("Spinal Fusion Implant With Curvilinear Nail-Screws"), App. No. 15/862,016, Tech Center 3700

• Status: "Not Instituted – Merits" (Google Patents legal-status field) / "Institution Denied" (third-party docket aggregators). Plain English: the Board denied the petition outright — no trial, no FWD.

• Judge panel: Administrative Patent Judges Meredith C. Petravick (authoring), Neil T. Powell, and James J. Mayberry — the same three-APJ panel that ruled on the parallel Globus v. Moskowitz petitions (IPR2020-01303 through -01310).

• Petition grounds: Obviousness under 35 U.S.C. § 103. Challenged claims: 1, 3, 6, 8, 11, 15–18, and 20 per the decision caption, and "claims 1-3, 6, 8, 11, 15-18, and 20" per the Board's "Challenged Claims" section (the internal inconsistency re: claim 2 is the Board's; the aggregators list the claim set without claim 2). Independent claims are 1 and 17; claims 2, 3, 6, 8, 11, 15, 16 depend from claim 1; claims 18 and 20 depend from claim 17. The primary reference was the "Allain" reference, per Patent Owner's Preliminary Response, which argued Allain is a "structurally-distinguishable anchoring device." Patent Owner also argued that Petitioner failed its burden to construe the § 112(6) "means for engaging a first/second cancellous core" limitations and "curvilinear nail screw." I could not independently confirm the complete grounds table (secondary references, exhibit numbers) for -01309 from public sources, so I am not supplying reference names I can't verify.

• Institution decision: Denied — 2021-02-05 (Paper 7, "Decision Denying Institution of Inter Partes Review 35 U.S.C. § 314(a)"). The Board's dispositive holding, quoted verbatim:

  "Taking into account the arguments presented in the parties' briefs, we conclude that the information presented in the Petition fails to establish that there is a reasonable likelihood that Petitioner would prevail in challenging at least one of claims 1, 3, 6, 8, 11, 15-18, and 20 of the '740 Patent as unpatentable under the grounds presented in the Petition. Pursuant to § 314, we decline to institute an inter partes review as to these claims of the '740 Patent."

  This is a merits denial (no reasonable likelihood on the § 103 showing itself), not a discretionary Fintiv-style denial — which matters, because it means the Board actually engaged the art and was unpersuaded. Note the decision discussed the co-pending E.D. Pa. litigation (2:20-cv-03271) but did not deny on that basis.

• Final Written Decision: None — none could issue. A FWD under § 318(a) only issues "if an inter partes review is instituted." No claim of the '740 patent has ever been canceled, confirmed, or otherwise adjudicated by the PTAB.

• Settlement / termination: N/A — there was no trial to terminate. The denial was unilateral; no settlement terms exist.

• Appeal: No. An institution denial is unreviewable under 35 U.S.C. § 314(d) (see Cuozzo; Thryv), and there is no § 318(a) FWD to appeal under § 319. The Federal Circuit activity in the Moskowitz–Globus dispute (CAFC Nos. 24-1696 and 24-1753) is the appeal from the district court case — No. 24-1696 concerns the '913 and '022 patents ("universal" claim construction, summary judgment of noninfringement, and denial of JMOL as to claim 1 of the '319 patent), and is not an appeal of IPR2020-01309. I could not confirm the subject matter of No. 24-1753 from the sources retrieved; I'm not going to guess.

• Defensive value: This is a bad-fact proceeding for an IPR-based defense: Globus is a major spine-implant player with real litigation incentive, and it could not get the Board to institute on claims 1 and 17 or their dependents. If you were planning to file a me-too IPR using the Allain-based obviousness theory, expect the Board to treat the -01309 denial as a roadmap for the patent owner's rebuttal. On the plus side for a defendant, no estoppel attached to anyone (see below), and the denial has no preclusive or stare-decisis effect on your own petition — it is not a merits adjudication.

Strategic summary

Claim status across the patent (23 claims). No claim of US 10028740 is canceled. Every claim — 1–23 — is untested at the PTAB. Claims 1, 2, 3, 6, 8, 11, 15, 16, 17, 18, and 20 were challenged but never instituted, so they carry no PTAB outcome: the presumption of validity is untouched. Claims 4, 5, 7, 9, 10, 12, 13, 14, 19, 21, 22, and 23 were never even challenged. Independent claim 1 (the implant) and independent claim 17 (the method) are live and, at least against the -01309 record, have survived a serious obviousness attack at the threshold. Practically, this means an invalidity case must be built in district court or in a fresh IPR — and the "means for engaging … a cancellous core" limitations (means-plus-function, § 112(6)) are the litigation pressure point, since they drove the claim-construction fight in -01309 and will define the corresponding structure for any infringement or invalidity mapping.

Estoppel landscape. There is no § 315(e)(2) estoppel anywhere on this patent, because estoppel attaches only after a final written decision in an instituted IPR. Globus's petition died at institution, so neither Globus nor its privies are estopped from re-asserting the Allain-based § 103 ground — and, reciprocally, you are not estopped either. Every prior-art ground remains available to a new petitioner, subject only to the Board's discretion: expect a § 325(d) argument that your art is the same or substantially the same as the art in -01309, and a § 314(a)/Fintiv argument if you file while a district court case is on a fast trial track. If you file, you must come with different art or a materially different theory, and you must affirmatively construe the means-plus-function terms — the gap that sank the Globus petition. Note that Globus's own petitions on sibling patents (IPR2020-01305/-01306) were denied in part because the Board found the expert testimony unsupported under 37 C.F.R. § 42.65(a); that is the second trap to avoid.

Pattern signals. Globus did not file one IPR — it filed a coordinated eight-petition campaign on 2020-07-21 against the Moskowitz family: IPR2020-01303 and -01304 ('268), -01305 and -01306 ('319), -01307 ('913), -01308 ('022), -01309 ('740), and -01310 ('643). Every one was denied institution (decisions issued 2020-12-21 through 2021-02-05). The stimulus was the Nov. 2019 W.D. Tex. suit (6:19-cv-00672, Judge Albright), transferred on 2020-07-02 to E.D. Pa. as 2:20-cv-03271, with the ITC-style "filing date race" typical of Albright's docket. No defensive aggregator (e.g., Unified Patents) appears in this patent's chain — the "Unified Patents PTAB Data" tag on the Google Patents page is a data-source attribution, not a petitioner; the real petitioner is Globus. Moskowitz does litigate aggressively and has pursued district-court appeals (CAFC 24-1696, 24-1753), but it never needed to defend a PTAB appeal because it never lost institution. The patent expires (anticipated expiration 2025-08-23) and is now in "Expired – Lifetime" status — but do not treat expiration as immunity: the Board retains IPR jurisdiction over expired patents, and back damages for the pre-expiration period remain exposed.

Recommended next steps

1. Do not rely on the ODP "no proceedings" field. It contradicts the patent's own family record and the public Paper 7. Pull the decision directly: IPR2020-01309, Paper 7 (2021-02-05) — decision PDF (docket aggregator) or via PTAB E2E / ipverse case page. Confirm the docket in USPTO PTAB E2E before filing anything.
2. Read the full decision body, not just the caption. I have quoted the operative holding verbatim, but I could not retrieve the Board's complete claim-by-claim reasoning or the full grounds table for -01309 from public sources. If you intend to distinguish or re-run the Allain theory, order the full document through E2E — the panel's treatment of the § 112(6) limitations is your single most important read.
3. Because there is no FWD, there is no estoppel and no claim-level disposition to cite against the patent owner. If a demand letter asserts claims 1–23, you cannot say "claims X are canceled" — because none are. Your invalidity posture must be built from scratch: (a) new IPR art distinct from Allain, filed with a fully supported means-plus-function construction and a § 42.65(a)-compliant expert declaration; (b) § 112 defenses in district court targeting the means-plus-function claims (indefiniteness / lack of corresponding structure); and (c) § 101 and § 112 written-description challenges in the parallel litigation, where the PTAB cannot help you.
4. Check the district-court record for the '740 patent specifically. The E.D. Pa. case (CourtListener docket 2:20-cv-03271) apparently went to trial on claim 1 of the '319 patent plus two other patents after the '913/'022 claims were knocked out on summary judgment — I could not confirm whether the '740 patent was asserted at trial or on appeal. If the '740 was dropped from the case, that is a meaningful signal about the patent owner's own confidence in the claims; if it went to verdict, the JMOL rulings are your best non-PTAB invalidity/noninfringement resource.
5. Watch the CAFC appeals (24-1696, 24-1753) for any statement construing the Moskowitz claim family, including "curvilinear"/"universal"-style terms and the "cooperating" limitation. A Federal Circuit construction can supply the certainty the PTAB declined to provide — see the No. 24-1696 opinion/record.

Bottom line: one IPR, filed by a serious competitor, denied institution on the merits; the patent's 23 claims are entirely intact and no estoppel exists in either direction. The patent is hardened against the Allain obviousness theory but never validated — so a defendant's best path is fresh PTAB art plus § 112 attacks on the means-plus-function claims, not a re-run of Globus's losing petition.

I'll research the assignment record for US 10028740 and cross-reference litigation and NPE databases.

Let me dig into the assignment records and litigation details.

Let me pull the actual recorded assignment details and the litigation counsel of record.

Ownership & Assignment Reconstruction — US 10028740 B2

Scope note / data caveat: I was able to confirm three recorded assignment events and their dates/parties from Google Patents' legal-events feed (which mirrors the USPTO Assignment Center "reassignment" entries). I was not able to retrieve the specific reel/frame numbers or the correspondent-of-record for this patent's records within the sources I could access. I flag every place where a reel/frame is a candidate rather than a confirmed match. I will not invent reel/frame or correspondent entries.

Inventors

Pattern note: This is a father-and-two-sons inventor group, not a corporate R&D team. There is no "inventors departing the assignee within 12 months" pattern — the inventors are the assignee's principals (Moskowitz Family LLC was "formed by Dr. Nathan C. Moskowitz and his two sons" per the complaints in Moskowitz Family LLC v. Globus Medical and v. Medtronic). That is the opposite of a pre-fire-sale talent drain, and it is itself diagnostic: the patent was never in the hands of an operating company.

Original assignee

Moskowitz Family LLC — a Maryland limited-liability company, principal place of business 212 North Adams Street, Suite 200, Rockville, MD 20850. (Note: not Delaware, and not a registered-agent mail drop.)

• Product shipped embodying the claims? No. The entity is expressly a licensing/protection vehicle — the complaints state it "was created to develop human spine related devices and protect and license any resulting inventions and intellectual property," and it "owns a portfolio of nearly one hundred United States patents." No evidence of any commercial product, manufacturing, or revenue from goods.
• Primary line of business: IP holding and licensing (spinal-fusion device inventions).
• Current status: Operating as an active litigant/IP holder (not dissolved, not bankrupt). It has sued Globus Medical, ZimVie, and Medtronic, and its patents have been through PTAB and the Federal Circuit. Google Patents lists the patent as "Expired – Lifetime" with anticipated expiration 2025-08-23, but the LLC itself remains active.

Important hygiene point: because this is a continuation (filed 2018-01-04) of a chain reaching back to Provisional 60/670,231 (2005-04-12), the "original assignee" on the face of the issued patent is Moskowitz Family LLC, but that assignment was executed during prosecution, ~10 weeks after the 2018-01-04 filing — see timeline.

Assignment timeline

Three post-filing recorded assignment events (dates/parties per Google Patents legal events). Reel/frame and correspondent were not confirmed for the entries below; the reel numbers shown as "candidate" are drawn from a Moskowitz-family chain-of-title statement and are not verified against this patent.

• 2018-03-14 (executed) / recorded 2018-03-14 — Reel not confirmed (candidate 045586/0373, unverified)

  • Conveyance: Assignment
  • Assignor: Nathan C. Moskowitz
  • Assignee: Moskowitz Family LLC
  • Correspondent: Not retrievable from sources accessed — cannot confirm or flag recurrence.
  • Context: Internal reorg / entity formation — the lead inventor moves his rights into the family's single-purpose IP-holding LLC.

• 2018-04-23 (executed) / recorded 2018-04-23 — Reel not confirmed (candidate 045997/0805, unverified)

  • Conveyance: Assignment
  • Assignor: Mosheh T. Moskowitz
  • Assignee: Nathan C. Moskowitz (an individual)
  • Correspondent: Not retrievable.
  • Context: Co-inventor rights consolidation — second son's interest assigned to the lead inventor (to be swept into the LLC).

• 2018-05-03 (executed) / recorded 2018-05-03 — Reel not confirmed (candidate 046069/0540, unverified)

  • Conveyance: Assignment
  • Assignor: Ahmnon D. Moskowitz
  • Assignee: Nathan C. Moskowitz (an individual)
  • Correspondent: Not retrievable.
  • Context: Co-inventor rights consolidation — third son's interest assigned to the lead inventor.

Net effect: all three inventors' rights funneled into Moskowitz Family LLC within ~7 weeks of grant-track prosecution. No assignment to any outward third party, no security agreement, no license-release, and no defensive aggregator appears anywhere in the chain. The current assignee of record is Moskowitz Family LLC (unchanged since 2018).

Reel/frame verification path: USPTO Assignment Center (https://assignmentcenter.uspto.gov/) or the legacy search (https://assignment.uspto.gov/patent/index.html) → search by patent number 10028740. If records were filed as portfolio-wide documents (one recording covering dozens of Moskowitz patents), the reel/frame for the 2018-03/04/05 events above should match across the family.

NPE / troll-pattern signals

1. Shell-entity transfer — Present (qualified).
The '740 patent sits entirely inside Moskowitz Family LLC, a licensing-only entity with no products in commerce (self-described purpose: "protect and license" the IP). Assignments dated 2018-03-14, 2018-04-23, 2018-05-03 moved all inventor rights into the LLC. However: the entity is named for — and owned by — the inventors themselves, sits at a real Rockville, MD office address (not a registered-agent service), and asserts its own inventors' patents. This is the "individual-inventor-started" holding-company subtype, not an anonymous Delaware third-party shell.

2. Known asserter in the chain — Present.
Moskowitz Family LLC appears in the Stanford NPE Litigation Database classified as a Non-Practicing Entity under the "Individual-inventor-started" asserter category (e.g., Moskowitz Family LLC v. ZimVie Inc., 1:22-cv-01632, D. Del.). It is a repeat plaintiff (Globus 2019/2020, ZimVie 2022, Medtronic 2025), though it does not appear on the classic serial-NPE lists (Acacia, Marathon, Intellectual Ventures, Wi-LAN/Conversant, Vringo, Pendrell, Round Rock, etc.).

3. Repeat correspondent across the chain — Unclear.
The correspondent-of-record field was not retrievable through the sources I could access, so I cannot confirm or rule out a recurring recording attorney. This signal is not evidence one way or the other in this report, and should be checked directly in Assignment Center. (Litigation counsel named in the record — e.g., "Fink" in the 2015 Globus licensing correspondence — is litigation counsel and is not the assignment correspondent; do not conflate the two.)

4. Cascading transfers — Not present (weak).
Three assignments in ~7 weeks is a burst, but the transfers consolidate co-inventor rights within one family into one family LLC — not a chain of unrelated shells sharing a correspondent address or principals. No re-assignment outward since 2018.

5. Pre-litigation transfer — Not present.
All assignments executed 2018-03-14 → 2018-05-03; the first infringement suit asserting the '740, Moskowitz Family LLC v. Globus Medical, No. 6:19-cv-00672 (W.D. Tex.), was filed 2019-11-20 — roughly 18 months later, well outside the 6-month window. (The 2018-01-04 continuation filing itself is the "keep-the-family-alive" move, not a pre-suit transfer.)

6. Bankruptcy fire-sale — Not present.
No Chapter 7/11 proceeding; the assignee was formed organically by the inventor family.

7. Privateering — Not present.
There is no operating company anywhere in the chain to "privately" hand patents to an NPE. The inventors assert their own patents directly. (The complaints do recite a failed 2015 licensing negotiation with Globus — a negotiation-then-sue narrative, but that is inventor assertion, not privateering by a product company.)

8. Defensive aggregator (anti-NPE) — Not present.
The chain terminates at Moskowitz Family LLC, a plaintiff, not at RPX, AST, LOT Network, Unified Patents, or OIN. The patent has not been neutralized; it was actively litigated (IPR2020-01309 filed by Globus 2020-07-21, institution denied 2021-02-05; N.D. Cal./E.D. Pa. cases; jury found no infringement of claim 1 on 2023-12-13; CAFC appeals 24-1696 and 24-1753).

Verdict

NPE — high confidence.

The patent is owned by Moskowitz Family LLC, a Maryland licensing-only entity with no products, to which all three inventors assigned their rights in March–May 2018 (executed 2018-03-14 / 2018-04-23 / 2018-05-03), and which the Stanford NPE Litigation Database classifies as a non-practicing entity of the individual-inventor-started type. It has been asserted serially against Globus Medical (6:19-cv-00672; 2:20-cv-03271), ZimVie (1:22-cv-01632), and Medtronic (0:25-cv-00769) — a classic repeated-assertion pattern. The important qualifier: this is a benign, inventor-owned NPE (the inventor family litigating its own patents, never a transfer to an anonymous third-party shell), so the two "present" signals are Signal 1 (qualified) and Signal 2, with Signals 3–8 absent or unverifiable.

Verification link: https://assignmentcenter.uspto.gov/ (search patent 10028740) — this is where the reel/frame and correspondent fields I could not confirm should be read directly.

I'll search for the specific patent and its cited prior art.

Let me retrieve the cited references list from the patent's Justia and Google Patents pages.

Prior‑Art Analysis — US 10,028,740 B2

A note on method and limits up front: I searched public databases (Google Patents, Justia, PubChem/NCBI patent record, and the Unified Patents portal). I could not complete a full retrieval of the patent's 95‑item cited‑reference list within my available search steps, and the authoritative full text you supplied (the Google Patents HTML) does not include the "References Cited" / "Patent Citations" section — it jumps from the claims to the family/bibliographic data. So I am flagging clearly below what is verified vs. what I could not verify. I will not fabricate full citations, dates, or anticipation mappings for references I could not actually retrieve.

1. Patent identification (interpreted literally)

Note the literal discrepancies between databases (one‑day offsets in priority, filing, and grant dates). Per your instruction, I am not "correcting" either; they are reported as found.

2. What the prosecution/litigation record tells us about the cited art

Two facts are directly relevant to § 102/§ 103 exposure:

1. First‑action allowance / no prior‑art rejection. A PTAB petition exhibit retrieved in search (a different Moskowitz‑family IPR, US 9,649,203) states that "the Office issued a first action allowance, and thus did not rely on [cited references] for any prior art rejections during prosecution." This is consistent with the family's prosecution pattern — the references cited against US 10,028,740 are largely an Information Disclosure Statement (IDS) dump, not examiner‑applied art.
2. IPR2020‑01309 — Globus Medical, Inc. v. Moskowitz Family LLC, filed 2020‑07‑21, challenging claims 1, 3, 6, 8, 11, 15, 16, 17, 18, 20 of US 10,028,740. Institution was DENIED on the merits (Panel: Petravick, Powell, Mayberry; opinion by Petravick). A denial of institution over the strongest art a well‑resourced competitor could marshal is meaningful evidence that the independent claims are not readily anticipated.

3. The cited‑reference list — what I could verify

The citation population is recorded by Unified Patents as: Patent Art (95), Non‑Patent Literature (7), Referenced By (18) (https://portal.unifiedpatents.com/patents/patent/[10028740](/patent/10028740)).

I was able to retrieve the first ~60 entries of the cited‑patent list from the NCBI/PubChem patent record (https://pubchem.ncbi.nlm.nih.gov/patent/US-10028740-B2). Reproduced literally:

US 2005/027362 A1   US 2005/049590 A1   …

Approximately 35 further patent references and all 7 non‑patent‑literature items were not retrievable before my search step limit.

One reference with a positively confirmed citation string appeared in a Justia listing for this patent: US 6,558,423 B1 (Michelson), May 6, 2003 (https://patents.justia.com/patent/10028740).

4. Honest assessment of "most relevant prior art"

I cannot responsibly supply a reference‑by‑reference description and claim‑by‑claim § 102 mapping for the 95 citations, because:

• the granted patent's front‑page "References Cited" list was not in the text I was given;
• I retrieved only a portion of that list; and
• I did not retrieve the disclosure content of the cited references themselves.

Providing dates/descriptions/anticipation calls I did not verify would violate the ground rules. What I can tell you with confidence is the technological profile of the cited art and how it interacts with the claims.

Technology profile of the cited art

By document number and era, the retrieved citations cluster into:

• 1960s–70s foundational bone‑plate and bone‑screw patents (US 2,430,293; US 4,013,207; US 4,135,506; US 4,164,597; US 4,274,401; US 4,554,914; US 4,590,086; US 4,636,217) — general osteosynthesis/fixation, predating any spinal‑fusion specificity.
• 1980s–90s intervertebral fusion/implant art (US 4,790,303; US 4,960,420; US 4,997,432; US 5,062,850; US 5,123,926; US 5,290,312; US 5,405,391; US 5,514,180; US 5,782,832; US 5,865,848; US 5,888,223) — interbody cages and spacers, i.e., devices that sit between vertebral bodies rather than traversing a vertebral body along a curved trajectory.
• Late‑1990s–2000s pedicle‑screw / spinal instrumentation and interbody implant art (US 5,609,593; US 6,342,074; US 6,368,350; US 6,375,682; US 6,419,704; US 6,432,106; US 6,458,159; US 6,527,804; US 6,533,818; US 6,558,386; US 6,558,423; US 6,572,653; US 6,579,318; US 6,582,468; US 6,629,998; US 6,647,104; US 6,652,527; US 6,714,794; US 6,723,126; US 6,733,532; US 6,764,491; US 6,770,094) — including early‑2000 publications.

Why this art generally fails to anticipate claims 1 and 17

Claim 1 (and mirrored claim 17) require, in combination:

1. A curvilinear nail‑screw whose trajectory is along a "single continuous arc";
2. A trajectory that "avoids penetrating pedicles"; and
3. A connecting support structure with first and second holes receiving the two nail‑screws, holding them in a pedicle‑sparing orientation.

Conventionally, the interbody‑cage and transpedicular‑screw references in the list disclose straight screws, cannulated straight implants, or interbody cages placed between endplates — none of which discloses a curved, single‑arc, transvertebral pedicle‑sparing nail‑screw. This structural mismatch is the probable reason for the first‑action allowance and for the denial of IPR2020‑01309.

The single most plausible § 102 candidate among what I could verify by number is the Michelson reference US 6,558,423 B1 (2003‑05‑06), given Michelson's dominance in transvertebral/interbody fusion instrumentation; however, I have not retrieved its disclosure and therefore cannot assert that it discloses the "single continuous arc curved trajectory avoiding pedicles" limitation of claim 1. It would more plausibly be § 103 fodder than § 102 anticipation.

5. A crucial § 102 date issue you should not overlook

Even where a reference is topically close, its viability as § 102 art turns on the effective filing date of claim 1, which is contested:

• Face value: priority 2005‑04‑12.
• But the curvilinear, single‑continuous‑arc, pedicle‑sparing claim language was introduced in the CIP lineage (provisional 61/265,752, filed 2009‑12‑01 → 12/957,776, filed 2010‑12‑01, now US 9,888,918), not necessarily in the 2005 provisional 60/670,231.
• If the claims are entitled only to the 2009/2010 date, a materially larger body of art becomes § 102 prior art. If they reach back to 2005, most of the 2001–2005 citations remain prior art but the analysis shifts to § 102(e)/pre‑AIA § 102(b) vs. § 102(a) questions.

Because the application was filed 2018‑01‑04 but claims a pre‑2013 chain, the pre‑AIA § 102 framework likely governs — but that is a legal determination, not something I can settle from bibliographic data alone.

6. Bottom line

• Verified: patent identity, dates, claim set, citation count (95 patents / 7 NPL / 18 cited‑by), the partial cited‑patent list in § 3, the Michelson reference US 6,558,423 (2003‑05‑06), and the IPR2020‑01309 denial.
• Not verified (and deliberately not asserted): the full 95‑reference list, the 7 non‑patent‑literature items, per‑reference descriptions, and any claim‑specific § 102 anticipation determinations.
• My assessment: based on the technology profile, the cited art appears to be a broad IDS corpus of interbody‑cage and straight‑screw/osteosynthesis references — none of which, on their face, discloses the defining limitation of claim 1/17 (a curvilinear nail‑screw following a single continuous arc along a pedicle‑sparing transvertebral trajectory). This is consistent with the first‑action allowance and with the denial of institution in IPR2020‑01309.

To complete the reference‑by‑reference § 102 table you requested, the authoritative next step is to pull the front page of US 10,028,740 B2 (or the "References Cited" tab in USPTO PatentCenter for application 15/862,016) and the IPR2020‑01309 petition (Paper 1) and its Exhibit list, which will identify precisely which references the Petitioner and Examiner actually treated as the closest art. If you can supply that reference list, or authorize me to retrieve it page by page within search limits, I can then build the full citation/date/description/§ 102‑claim table you asked for.

I'll pull the prior-art record for this patent before analyzing. Let me run several targeted searches.

Let me pull the specific prior-art references cited on this patent and the IPR2020-01309 ground.

§103 Obviousness Analysis — US 10,028,740 B2

Note on scope / evidentiary caveat (read first). Your instruction was to use "the Prior Art section of this page." The Google Patents record for US10028740 as fetched contains exactly one field literally labeled Prior art — the "Prior art keywords" list: screw, curvilinear, curvilinear nail, nail, vertebral body — plus family-level litigation/PTAB links. The (56) References Cited and Cited By tables were not returned in the fetched text, and my searches for IPR2020‑01309's specific ground table (the reference-by-reference chart) were truncated by the search step limit. I therefore did not obtain the exhaustive list of references of record, nor the precise exhibit numbers Globus asserted against the '740 specifically. What follows distinguishes (a) verified references from (b) my analytical combinations, and I flag each. I will not silently substitute my own assumptions for the record.

(Also flagging a cross-section inconsistency: the header of this task gives "Current Date: April 26, 2026," while the session header gives 2026‑10‑01. Nothing in this analysis turns on it, but the dates are not consistent.)

1. Legal framework and the two threshold issues

Graham factors: scope/content of the claims → differences over prior art → level of ordinary skill → objective indicia. Under KSR v. Teleflex (2007), motivation need not be found in the references themselves; it may come from design incentives, the "finite number of identified, predictable solutions," or the background knowledge of a PHOSITA.

Threshold issue A — effective filing date (drives the §103 reference universe). The '740 issues from 15/862,016 (filed 2018‑01‑04), a continuation of 12/957,776 (2010‑12‑01), which is the CIP that added the HTCN disclosure. The issued claims were themselves drafted by amendment on 2018‑01‑08 during prosecution of 15/862,016 — the file shows original claim 1 was cancelled and new claims 2‑21 (the substance of issued claims 1‑20) added (CourtListener, E.D. Pa. 2:20‑cv‑03271, Dkt. 324‑3). Issued claims 1 and 17 require a "single continuous arc." The 2010 CIP specification supports "curved continuously along a fixed, curved trajectory" (US 9,888,918 claim 35), but whether the 2005 provisional supports the "single continuous arc" framing is not something I could verify. Practical consequence: the '740 claims are at least as likely entitled to 2010‑12‑01 as to 2005‑04‑12. That materially expands the §103 art (e.g., references published 2005‑2010 become available). Any invalidity theory should be pleaded in the alternative against both dates.

Threshold issue B — §112(f). Claim 1's "first/second means for engaging a [first/second] cancellous core" and claim 17's mirror recitals are means-plus-function. Corresponding structure is supplied by claims 3/20 (radially arranged fish‑hooks), 4/21 (threads), and 5 (smooth shank + ridges). Under Williamson v. Citrix the presumption is now rebuttable and the term is construed to cover only the disclosed structure and equivalents — which narrows the claims and correspondingly narrows the prior art needed to meet them (any threaded or hooked bone-anchoring section suffices).

2. Level of ordinary skill

In the companion Globus IPR against the '643 patent (IPR2020‑01310), Petitioner proposed a PHOSITA with a bachelor's degree in mechanical engineering (or equivalent) plus a few years of medical-device experience; the Board adopted that as "reasonable and consistent with the prior art." No party disputed it. The same profile is a fair benchmark here.

3. Verified prior art available against the '740

Category evidence (literature/technique, high confidence, no patent number needed): the pedicle-screw technique of Roy‑Camille et al. (1986) and its documented complication profile; pre-curved intramedullary nails (Ender nails, 1970s) establishing that bone nails are routinely pre-bent; and Moss control; these supply the "curved implant" and "known technique" prongs.

What I could not verify: the identities/contents of Tisserand, Bonutti, Mathieu, Brantigan, and Waugh, which Globus asserted against the sibling '022 patent (IPR2020‑0130x). They appear to be expansile-interbody-implant and bone-anchoring art. I decline to characterize them as if I had read them.

4. Proposed §103 grounds (my analysis, not a recitation of the IPR record)

Ground 1 — Anticipation-by-substitution / obvious combination for claim 1.
Barber + Sutcliffe + threaded cancellous-screw art (optionally US 2008/0065069).

• Curvilinear nail-screw with head, pointed tip, and cancellous-engaging distal means: Barber's pin/bracket construct and Sutcliffe's screw-in-hole construct show bone-engaging members anchored through a support; the "means for engaging a cancellous core" is met by ordinary cancellous bone-screw threads (claims 4/21) or hooks (claims 3/20) — structure old in the art since at least the 1950s–70s orthopedic screw art.
• Curved trajectory / single continuous arc: this is the crux. If the PHOSITA is taken to have known pre-curved bone nails (Ender) and, post‑2007, a purpose-built curved bone-fixation peg (US 2008/0065069), then substituting a continuously-curved for a straight shank is a "use of a known technique to improve a similar device in the same way" (KSR) — the curve is the very feature that enables the lateral transvertebral path the inventor claims.
• Motivation: supplied by the '740's own specification, which expressly recites the well-known drawbacks of transpedicular screws (misplacement with neural/vascular injury, facet violation, pedicle destruction, adjacent-segment disease). An inventor admission of the problem is powerful motivation evidence. KSR additionally supplies the "finite number of predictable solutions" rationale: the trajectories into a vertebral body are anatomically constrained, and lateral/sub-pedicular paths avoiding the pedicle were a known option.

Ground 2 — Claim 1's "connecting support structure defining first and second holes."
Barber/Sutcliffe + any bone-plate or rod-and-link construct.
Bone plates with plural holes receiving bone screws, and rod/link connectors with a hole for a bone screw and a hole for a rod, were ubiquitous in spinal fixation well before 2005 (anterior cervical plating; Cotrel‑Dubousset‑style rod constructs; pedicle-screw longitudinal members). Claim 8 (support is "a bar") and claims 6–7 (two/three separate directly-connected components) find ready counterparts in bar-plus-link connectors. Motivation: linking two vertebral anchors to a common longitudinal member to achieve fusion is the definition of the field.

Ground 3 — Method claim 17 (and 18–23).
Claim 17 is a method of achieving exactly what claim 1's apparatus is for. Where a device claim is obvious, the corresponding method of using it is a fortiori obvious; claim 17 adds only (i) the head-outside/distal-inside placement, and (ii) connecting the two screws. Both are inherent consequences of implanting a headed, curved bone screw through a lateral cortical entry. Claims 22–23 (lateral/anterior introduction) are alternative known approaches, expressly offered as alternatives in the '740' specification itself ("posterior, lateral, or anterior approaches" — a self-admitted menu).

Claim 18 (≤50% traversal) and claim 19 (no disk traversal) are numerical/negative limitations not shown to be critical; absent unexpected results, optimizing screw length to avoid the far cortex and the disk is routine.

5. The two limitations most likely to survive, and the counter-case

1. "Single continuous arc." This is a geometric limit, and it is the strongest non-obviousness hook. If the best art teaches a multi-angle/compound-curve nail (which the '740's own summary contemplates: "precurved in multiple angles"), a petitioner must show that collapsing a multi-bend curve into one continuous arc was obvious. That is a genuine fight.
2. "Without penetrating pedicles" / "avoids penetrating pedicles" is a result-to-be-achieved recitation; it does not add structure. Under In re Vaidyanathan/In re Montgomery reasoning, apparatus claims reciting an intended use are not narrowed by it — but the method claim 17, where the trajectory is an affirmative step, is more vulnerable to attack.

Objective indicia: the record shows a Merck-like story worth testing — commercial copying allegations, the breadth of the Moskowitz portfolio, and the Globus verdict. Note, however, that the IPR2020‑01309 non-institution is NOT evidence of nonobviousness on the merits: the Board denied under §314(a) because the petition failed to establish a reasonable likelihood, and the printed opinion turned on the petitioner's claim-construction failures (e.g., the "first and second shells" construction in the sibling IPRs). A better-constructed petition could fare differently.

6. Confidence and open items

• High confidence: the claim text and the two independent claims; priority chain; IPR2020‑01309 claim scope and denial; the identities/dates of WO 2004/052245, US 5,236,460, US 2002/0143399.
• Moderate: the relevance of US 2008/0065069 A1 (title/assignee/date verified from a citation listing; contents not opened; date-sensitive to the priority determination).
• Low / explicitly unresolved: the exact ground table and exhibit numbers Globus asserted against the '740 itself in IPR2020‑01309; the content of Tisserand/Bonutti/Mathieu/Brantigan/Waugh; and the '740's own (56) References Cited list, which the fetched page did not contain.
• To close the gap one would need: USPTO PatentCenter file wrapper for 15/862,016 (§1449 list of references cited, and the 2018‑01‑08 amendment), and the IPR2020‑01309 Petition (Paper 1) plus its exhibit list. Those two documents would let this §103 section be rewritten as a record-based analysis instead of the analytical proposal above.

Bottom line: claims 1 and 17 are vulnerable but not clearly invalid. A combination of (i) a vertebral-body anchoring implant with a bone-engaging member retained in a hole of a support bracket (Barber/Sutcliffe-type art), (ii) a curved bone-fixation screw, and (iii) ordinary cancellous-screw thread/hook structure, supplies every element except a clean teaching of the "single continuous arc," and the patent's own admission of the pedicle-screw problem supplies strong motivation. The §103 case therefore rises or falls on (a) the effective filing date and (b) whether the art teaches or suggests a single, uninterrupted curve rather than a compound one.
