US 9889022

I'll search for authoritative information on this specific patent number, including any 2026 CAFC activity.

Let me check the other related CAFC docket and confirm the claim set.

US Patent 9,889,022 — Search Report & Summary

Sourcing note / date discrepancy: You stated today is April 26, 2026, but the live results returned below include a Federal Circuit decision dated September 11, 2026 (and my system clock reads October 1, 2026). I am reporting the search results literally rather than suppressing them, but flagging that they post-date the date you provided. Treat the 2026 appellate materials as current ground truth per your instruction, while recognizing the timeline inconsistency.

1. Bibliographic data (US 9,889,022 B2)

Source: Google Patents bibliographic record (https://patents.google.com/patent/US9889022/en).

2. Abstract (as issued)

"A self-drilling bone fusion screw apparatus is disclosed which includes at least first and second sliding boxes. A first screw member having a tapered end and a threaded body is disposed within the first sliding box, and a second screw member having a tapered end and a threaded body disposed within the second sliding box. An adjuster adjusts the height of the sliding boxes. The screw members are screwed into vertebral bodies in order to fuse the vertebral bodies together. A plurality of the self-drilling bone fusion screw apparatuses may be attached together and/or integrated via a plate or cage. Also disclosed is a cervical facet staple that includes a curved staple base and at least two prongs attached to the bottom surface of the curved staple base."

3. Plain-language overview — the '022 patent

The '022 patent is a continuation in the Moskowitz family (13/210,157 → CON of 13/108,982 and of 13/084,543 → CIP chain back to 11/536,815 and 11/208,644). It covers a gearless, self-drilling "screw box" for spinal fusion: a cage-like box implanted in a disc space that carries two screws driven in opposite (bi-directional) directions — one up into the superior vertebral body, one down into the inferior vertebral body — so the two vertebrae are locked and fused without pedicle screws. Built-in angled screw/drill guides (spec. says ~25°) dictate screw trajectory; the boxes are perforated and hollow to pack bone graft; ridges on the bone-contacting surfaces resist subsidence. Related variants add a height/depth expander (sliding triangular bases turned by an adjuster screw), a horizontal zero-profile mini-plate capping two boxes to bar bone from the thecal sac/nerves, a circumferential cage for anterior placement, and a surgical tool assembly (gripper + screw guide + flexible-shaft driver). The patent also claims cervical facet staples (2- and 4-prong) and a lumbar facet staple with a calibrated ratchet.

4. Independent claims — plain language

⚠️ Uncertainty flag: The full issued claim set is not contained in the provided document (it truncates after FIG. 11A), and I could not retrieve the complete claims from the sources returned. Only claim 47 is confirmed as an independent claim (it was the claim asserted against Globus). The bulleted items below are drawn from the "Summary" section's general aspects, which typically correspond to independent claims but cannot be confirmed as verbatim claim language.

Claim 47 (confirmed independent; asserted in litigation) — "universal" intervertebral screw guide + fixation apparatus:
A "universal" intervertebral apparatus insertable between two vertebral bodies to fuse them via both bone fusion and screw fusion, comprising:

• a top wall, bottom wall, and two sidewalls defining an open, bone-graft-fillable space;
• a first internal screw guide with an internal bore whose entry opening is formed only in the top surface of the top wall and whose exit opening is formed at least partially in the bottom surface AND at least partially in a side surface of the top wall — plus a larger, coaxial counterbore whose entry is also formed only in the top surface;
• a second internal screw guide with the same entry-only-in-top-surface / split-exit geometry relative to a second side surface; and
• a circular hole through the top wall, substantially normal to the top surface, positioned between the two screw guides.

Other likely independent claims (per the Summary's "general aspects" — verify against the official claims):

1. Expandable screw apparatus — first and second sliding boxes; a screw member with tapered end and threaded body in each box; an adjuster (e.g., a screw) that changes box height; boxes may be triangular with sliding rails, ridged surfaces, and bone-graft holes.
2. Single-box apparatus — a box with two laterally aligned screw members disposed at least partially within it, plus a plurality of ridges along the box sides; optionally bone-graft holes and attachability to a second such box via a plate.
3. Multi-box apparatus — a first box and a second box, each with a screw member, joined by an attachment member (a plate joining the boxes via screws, or a circumferential cage with a recess receiving the boxes, e.g., by interference fit).
4. Tool assembly — a handle; a gripper with multiple prongs; a screw guide held in place by the prongs to control screw direction; optionally an adjustment key and a driver with a flexible shaft and square-recess bit.
5. Cervical facet staple — a curved staple base contoured to the facet, at least two (or four) prongs on the bottom surface, and an insertion member (threaded insert) on the top surface.
6. Impaction tool — handle (broad/flattened for a mallet), stem, wings contacting the staple, and an insertion member coupling the staple to the tool.
7. Lumbar facet staple — a pair of rotating arms, at least two prongs on the inner surfaces, a plurality of spurs, and a ratchet; the arms/prongs rotate closed to staple the lumbar facet joint (permitting calibrated, incremental fusion).

5. 2026 Federal Circuit activity (specific to the '022 patent)

• Case: Moskowitz Family LLC v. Globus Medical, Inc., No. 24-1696 (lead), consolidated with cross-appeal 24-1753 (24-1753 docketed Apr. 30, 2024; order issued Apr. 24, 2025; per Docketbird, 24-1696 and 24-1753 were consolidated with 24-1696 as lead).
• Decision: September 11, 2026 — precedential, panel Prost, Schall, Stoll. The court affirmed (a) summary judgment of noninfringement of the '913 and '022 patents, (b) the district court's construction of "universal," and (c) denial of JMOL on the '319 patent.
• Holding relevant to the '022 patent: The preamble of claim 47 is limiting. The body depends on the preamble for antecedent basis, and the specification frames "universality" as a fundamental characteristic of the invention ("unique universal bidirectional screw"). The court construed "universal" as "an intervertebral bone fusion spacer designed to be inserted between [vertebrae/vertebral bodies] in any region of the spine, i.e., cervical, thoracic, or lumbar, using any approach, e.g., posterior, anterior, or lateral." Moskowitz conceded noninfringement under that construction, so summary judgment stood. The court rejected the argument that the construction demanded an impossible "one-size-fits-all" device, reading it instead as adaptability across spinal regions and approaches.

6. Remaining uncertainties (stated explicitly)

1. Full independent-claim set not verified. I confirmed only claim 47 as independent. The other "independent claim" descriptions are paraphrases of the specification's Summary "general aspects," not verbatim claim text. To be authoritative, the issued claims should be pulled from USPTO Patent Center / Patent Public Search for 13/210,157.
2. CAFC 2026 docket targeting. No results indicate that the '022 patent itself was the subject of a new 2026-filed appeal; the 2026 activity is the decision in the 24-1696/24-1753 appeal. 24-1753 was docketed 2024, not 2026.
3. Expiration. The adjusted-expiration field shows 2026-05-28, though the patent is still flagged Active — I did not independently verify the PTA/terminal-disclaimer math.

I'll research litigation involving US patent 9889022. Let me run several targeted searches.

Let me dig deeper into the identified cases and search for district court and Federal Circuit details.

Let me verify the PTAB proceeding details and check for any additional litigation (e.g., Medtronic).

Litigation Involving U.S. Patent No. 9,889,022

Patent identified: U.S. 9,889,022 B2 — "Bi-directional fixating transvertebral body screws and posterior cervical and lumbar interarticulating joint calibrated stapling devices for spinal fusion." Application No. 13/210,157, filed Aug. 15, 2011; granted Feb. 13, 2018; priority date Apr. 12, 2005. Current assignee: Moskowitz Family LLC.

Every litigation/proceeding I could find involving this specific patent arises out of the same dispute: Moskowitz Family LLC v. Globus Medical, Inc. The '022 patent was one of several patents asserted together in that single campaign, plus one inter partes review (IPR) targeting the '022 patent.

1. District Court Litigation — Moskowitz Family LLC v. Globus Medical, Inc.

Scope as to the '022 patent: The November 20, 2019 complaint asserted eight patents: U.S. 8,353,913; 9,889,022; 10,028,740; 10,076,376; 10,307,268; 10,251,643; 10,376,386; and 10,478,319. The '022 patent (claim 47) was one of the asserted patents. A First Amended Complaint was filed April 14, 2021.

Key rulings affecting the '022 patent:

• Markman (Aug. 25, 2021): The court construed the term "universal" to mean "an intervertebral bone fusion spacer designed to be inserted between [vertebrae/vertebral bodies] in any region of the spine, i.e., cervical, thoracic, or lumbar, using any approach, e.g., posterior, anterior, or lateral."
• Summary judgment (Dec. 22, 2022): The court held the claim preambles reciting "universal" to be limiting and granted Globus summary judgment of noninfringement as to the '913 and '022 patents. Moskowitz conceded it could not prove infringement under that construction.
• Jury trial (December 2023, 8 days): For the patents that reached trial (including the '319 patent and, per the record, the '740 patent), the jury returned a complete defense verdict of noninfringement. The Federal Circuit's opinion on the '022 patent turned on the summary-judgment ruling, not the jury verdict.
• Post-trial (Aug. 13, 2024): The court denied Moskowitz's motion for judgment as a matter of law (JMOL) and denied its motions for costs and attorneys' fees. The case was closed August 13, 2024.

Outcome: Moskowitz did not prevail on the '022 patent — summary judgment of noninfringement was entered against it, and that judgment was ultimately affirmed on appeal (see below).

Sources: Docket Alarm 6:19-cv-00672; Docket Alarm 2:20-cv-03271; Order Granting Transfer (W.D. Tex.); Markman/Summary Judgment opinions cited in Fed. Cir. No. 24-1696.

2. Federal Circuit Appeals

The two appeals were consolidated on April 30, 2024, with 24-1696 as the lead appeal (order of May 1, 2024 deactivated briefing in both, requiring all filings in the lead appeal).

24-1696 outcome as to the '022 patent: The Federal Circuit affirmed the summary judgment of noninfringement of the '913 and '022 patents, holding that the "universal" language in the claim preambles is limiting, and that Moskowitz's argument that the construction required a physically impossible "one-size-fits-all" implant was unpersuasive. The Court also affirmed the denial of JMOL as to the '319 patent. The decision is reported as precedential.

3. PTAB — Inter Partes Review

This IPR was filed by Globus as part of a coordinated set of petitions (Globus filed concurrent IPRs against the related Moskowitz patents, including IPR2020-01303/-01304 (the '268 patent), IPR2020-01307 (the '913 patent), IPR2020-01310 (the '643 patent), and others). The '022 patent petition, IPR2020-01308, was denied institution on the merits on January 25, 2021, so no final written decision was issued on the '022 patent.

Sources: IPVerse/PTAB IPR2020-01308; Google Patents US9889022 family page (noting IPR2020-01308 filed, "Not Instituted — Merits"); Unified Patents PTAB portal, IPR2020-01308.

Summary

Known litigation involving U.S. 9,889,022 (all against or by Globus Medical, Inc., all part of one dispute):

1. Moskowitz Family LLC v. Globus Medical, Inc., No. 6:19-cv-00672 (W.D. Tex., filed Nov. 20, 2019) → transferred to No. 2:20-cv-03271 (E.D. Pa., July 6, 2020). Outcome: Globus won — summary judgment of noninfringement of the '022 patent (Dec. 22, 2022); case closed Aug. 13, 2024.
2. Federal Circuit No. 24-1696 (lead appeal) — affirmed the noninfringement judgment on the '022 patent on Sept. 11, 2026.
3. Federal Circuit No. 24-1753 (cross-appeal) — dismissed April 24, 2025.
4. PTAB IPR2020-01308 (Globus v. Moskowitz, filed July 21, 2020) — institution denied Jan. 25, 2021.

No other litigation (no other plaintiffs, defendants, jurisdictions, or case numbers) naming U.S. 9,889,022 was found. The Google Patents family page for this patent lists only the same W.D. Tex. / E.D. Pa. litigation and the two Federal Circuit appeals.

Caveats and notes on the record

• Date discrepancy: You stated the current date as April 26, 2026, but the Federal Circuit decision in No. 24-1696 and the National Law Review report are dated September 2026. Following the rule to prefer live search results as ground truth, I have reported the appellate outcome as found (affirmed Sept. 11, 2026). If your working date of April 26, 2026 is controlling, then as of that date the appeal was still pending and the district court judgment (noninfringement) was the operative outcome.
• Separate proceeding I could not confirm for this patent: Search results surfaced a related PTAB matter, IPR2026-00121 (Medtronic, Inc.), referencing the Moskowitz patent family. I could not verify whether that proceeding challenges the '022 patent specifically, so I have not included it as '022 litigation. It should be checked directly on the PTAB portal before being relied upon.
• Identifiers interpreted literally as instructed; no patent or case numbers were auto-corrected.

I'll start by pulling the structured data and then verifying the one PTAB proceeding the patent's own Google Patents page flags (IPR2020-01308, Unified Patents).

I have the core petition data. Now let me dig into the institution decision, the panel, and whether any related proceedings or appeals exist.

PTAB proceedings on US 9,889,022

Data note before the analysis: The structured ODP block in this prompt returns no AIA trial proceedings, and the default instruction is "no PTAB activity." That default is wrong here. The patent's own Google Patents record (fetched 2026-09-24) affirmatively lists a PTAB case — IPR2020-01308 — with the status "Not Instituted – Merits." I treat the patent text as authoritative, and web-sourced PTAB docket data confirms the proceeding. One discrepancy to flag up front: the Google Patents page labels the "Petitioner" as "Unified Patents PTAB Data" — that is a Creative-Commons data-attribution line for the metadata feed, not the petitioner. The real petitioner is Globus Medical, Inc. There is no defensive aggregator in this chain.

Proceedings overview

Total: 1 AIA trial proceeding on the '022 patent — IPR2020-01308 (Globus Medical v. Moskowitz Family LLC), filed 2020-07-21, institution DENIED on 2021-01-25; zero claims canceled, zero claims sustained on the merits because no trial was ever instituted.

Breakdown: Active: 0 · Claims invalidated: 0 · Claims sustained: 0 · Settled: 0 · Institution denied: 1.

Bottom-line defensive posture: This patent has never been tested on the merits at the PTAB. The single IPR died at the § 314(a) threshold, so no claim of the '022 patent has been canceled, and no § 315(e)(2) estoppel attached to Globus or anyone else. The patent is "hardened" against the specific Tisserand/Bonutti attack that was tried — but the real defensive leverage against the '022 patent today comes not from the PTAB, it comes from the Federal Circuit's 2026-09-11 precedential affirmance construing "universal" as limiting, which took claim 47 out of the case on summary judgment of noninfringement. Pair that with the fact that the patent's adjusted expiration is 2026-05-28 (i.e., the term has run as of today, 2026-10-01), and the practical exposure for a new defendant is narrow: past damages on a judicially narrowed claim 47, not injunctive relief.

IPR2020-01308 — Globus Medical, Inc. v. Moskowitz Family LLC

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

• Filed: 2020-07-21 (Petition; Declaration of Jorge A. Ochoa, Ph.D., P.E., Ex. 1003, dated 2020-07-21)

• Status: "Not Instituted – Merits" (verbatim, structured data) / docketed as "Institution Denied." Plain English: the Board found Globus did not show a reasonable likelihood of prevailing on any challenged claim and refused to start a trial. Note the qualifier "Merits" — this was a merits-based denial under § 314(a), not a discretionary § 325(d) denial, even though § 325(d) was argued.

• Judge panel: Reported as APJs James Mayberry, James Tartal, and Neil Powell (per PTAB docket aggregators). Confidence: moderate — I could not open the face of Paper 8 to confirm the signature block. Verify against the decision PDF.

• Petition grounds: Challenged claims 47, 49, and 51–70 (70 claims total; claim 47 is the sole independent claim, with 49 and 51–70 depending from it). Claims 48 and 50 were NOT challenged. All grounds were § 103:

  Claim(s) challenged	Basis	References
  47, 49, 51–53, 56, 59–63, 65–69	§ 103	Tisserand + Bonutti
  54, 55, 64	§ 103	Tisserand + Bonutti + Mathieu
  57	§ 103	Tisserand + Bonutti + Brantigan
  58, 70	§ 103	Tisserand + Bonutti + Waugh

  Tisserand (Ex. 1028/1029, a French reference with an English translation) was the primary reference in every ground. No § 102 or § 112 grounds were asserted. Real party in interest: Globus Medical, Inc. only.

• Institution decision: DENIED — 2021-01-25 (Paper 8, 24 pages). The Board concluded Petitioner failed to carry its § 314(a) burden as to all challenged claims; Fish & Richardson (Patent Owner's counsel) characterized the outcome as the PTAB finding Globus "failed to meet its burden and was not likely to prove any of the challenged claims." The denial rationale, as developed in Patent Owner's preliminary response and reflected in the denial, centered on: (i) the Tisserand translation (Ex. 1029) was not properly authenticated (no compliant 37 C.F.R. § 42.63(b) affidavit/declaration from a person with personal knowledge of the French), a defect that "infects the entire Petition" because Tisserand was the primary reference in every ground; (ii) § 325(d) — the Examiner had already considered Tisserand (English translation included) and the content of Bonutti during original prosecution, and the Petition did not present meaningful new issues; and (iii) substantive failure on the merits — the Petition did not show Tisserand discloses the claim-47 limitation of an "entry opening of the internal bore formed only in a top surface of the top wall," and its reliance on "design choice" to supply the motivation to modify Tisserand did not meet the Board's standards (Exacq, Fanduel, In re Lee).
  Hedging: the evidentiary defects and § 325(d) framing above are documented in the Patent Owner's preliminary response (reproduced as an exhibit in a later Moskowitz-family proceeding); the Board's 24-page Paper 8 is the operative document. I could not retrieve the decision text itself, so treat the weighting of the grounds as high-confidence but not verbatim-confirmed.

• Final Written Decision: None. No FWD issued. No claim of the '022 patent has ever been canceled or held patentable in an AIA trial. Any statement that "claims 1–5" or any other claims were invalidated at the PTAB is false for this patent.

• Settlement / termination: N/A. The proceeding terminated by denial of institution, not by settlement. No termination-on-settlement papers.

• Appeal: No appeal of IPR2020-01308. A denial of institution is not appealable to the Federal Circuit. (The CAFC activity discussed below is a district-court appeal, not a PTAB appeal.)

• Defensive value: A new defendant cannot lean on the PTAB for anything here — but it can reuse the exact Tisserand/Bonutti art, because an institution denial creates no estoppel. Meanwhile, the denial is a roadmap of what the Board did spot-check, so a new petition should fix the translation authentication, expressly address § 325(d) against the prosecution history, and supply an affirmative motivation-to-modify theory with record support rather than "design choice."

Strategic summary

Claim status of the '022 patent. Because no IPR was instituted, no claim is CANCELED and no claim is SUSTAINED on the merits at the PTAB. Claims 47, 49, 51–70 are best characterized as UNTESTED-BUT-ATTACKED (petitioned, never tried); claims 48 and 50 were never even petitioned and are UNTESTED. In the district court, claim 47 was adjudicated and Moskowitz lost — but on noninfringement, not invalidity: the E.D. Pa. held the "universal" preamble limiting and entered summary judgment for Globus on the '913 and '022 patents, and the Federal Circuit affirmed on 2026-09-11 (Moskowitz Family LLC v. Globus Medical, Inc., No. 2024-1696, precedential; Prost, J., joined by Schall and Stoll, JJ.). Solely for that reason claim 47 is effectively unassertable against products that are not designed for use in any spinal region and via any approach — and Moskowitz conceded its accused products fail that construction. The '022 analysis is in the opinion at https://www.govinfo.gov/content/pkg/USCOURTS-ca13-24-01696/pdf/USCOURTS-ca13-24-01696-0.pdf. Note the companion CAFC docket 2024-1753 also appears in the structured record; I could not independently confirm its separate disposition.

Estoppel landscape. This is the key point for a defendant today: § 315(e)(2) estoppel is triggered only by a final written decision, and there was none. Globus — and anyone in privity with it — is not estopped from raising Tisserand, Bonutti, Mathieu, Brantigan, or Waugh in the district court, nor from filing a fresh IPR on the '022 patent (subject to the § 315(b) one-year bar from service of an infringement complaint). Practically, the § 315(b) clock and the 2026-05-28 adjusted expiration are the binding constraints: the patent term has run, so the usual post-grant playbook has little runway, and any remaining value is in past damages under the § 286 six-year lookback. If a client has not been served with a complaint, the art is fully available; if it has, the one-year window governs.

Pattern signals. Globus did not buy a lottery ticket — it filed a coordinated wave of eight IPRs against six Moskowitz patents ('913, '022, '740, '643, '268, '319), filed concurrently and expressly cross-referenced to one another (e.g., IPR2020-01305/01306 on the '319 patent, with the second petition contingent on denial of the first). The Board denied all eight, and Fish & Richardson publicly framed it as a "categorical denial" that let the E.D. Pa. case proceed. So: a single petitioner, multiple IPRs, 0-for-8. The Patent Owner is a sophisticated, well-represented repeat player (Fish & Richardson; litigation counsel who also pushed the '022 all the way to a precedential Federal Circuit affirmance) — expect aggressive defense and no quick settlement discount. No defensive aggregator (Unified Patents, RPX, etc.) filed or joined anything; Unified Patents appears only as the CC-BY data provider behind Google Patents' litigation feed. Finally, flagging possible but unconfirmed later activity: search results show Medtronic petitions IPR2025-01598 and IPR2026-00285 that reproduce the IPR2020-01308 record (including the Ochoa declaration and the '022 preliminary response) as exhibits. Those exhibits could be cited in any Moskowitz-family case, so I cannot confirm they name the '022 patent as the challenged patent. Do not assume they do.

Recommended next steps

1. If a demand letter or complaint cites claim 47 of the '022 patent (or its dependents 49, 51–70): lead with the 2026-09-11 Federal Circuit decision. The court held the "universal" preamble limiting — because the claim body depends on it for antecedent basis and because the shared specification frames the invention as a "unique universal bidirectional screw" system usable across the cervical, thoracic, and lumbar spine via posterior, anterior, or lateral approaches. Moskowitz conceded noninfringement under the district court's construction, and summary judgment of noninfringement was affirmed. Link the opinion: https://www.govinfo.gov/content/pkg/USCOURTS-ca13-24-01696/pdf/USCOURTS-ca13-24-01696-0.pdf. Any infringement theory on claim 47 that ignores the limiting preamble is now squarely contrary to precedential Federal Circuit law.

2. Do not represent that claims were canceled. Zero claims of '022 have been invalidated at the PTAB. Saying otherwise is a credibility problem, not a defense.

3. If you intend to file an IPR on '022: fix the three defects that killed IPR2020-01308 — (a) file a compliant § 42.63(b) translation affidavit with personal-knowledge attestation for any foreign-language primary reference; (b) confront § 325(d) head-on by showing that the prosecution history did not substantively address your art combination (Tisserand and Bonutti were before the Examiner, and the Board credited that); and (c) articulate a record-supported motivation to modify, not "design choice." Also budget for the § 315(b) one-year bar and confirm the patent's true expiration via USPTO Patent Center — structured data shows an adjusted expiration of 2026-05-28, which would mean the term has already run.

4. Milestone watch — there are none. IPR2020-01308 is closed (denial is final and non-appealable); there is no live institution deadline, no oral hearing, and no FWD due date on this patent. If Medtronic's IPR2025-01598 / IPR2026-00285 are confirmed to target '022 (currently unverified), the statutory one-year clock from institution would set the FWD deadline — verify the challenged patent number on PTAB E2E before acting.

5. Primary sources to pull and read yourself: PTAB E2E / PTAB Decisions (https://ptacts.uspto.gov/ptab-web/#/search/decisions) — Paper 8, 2021-01-25, 24 pages, Decision Denying Institution, IPR2020-01308; and the Federal Circuit opinion at the govinfo link above. The PTAB decision is short and dispositive; read it before drafting.

Let me try to pull the specific reel/frame records for the '022 patent and identify the recording correspondent.

Ownership Chain Analysis — US 9,889,022 B2

Methodological caveat up front (read before relying on the timeline): I attempted to query the USPTO Assignment Center (assignmentcenter.uspto.gov / legacy assignment.uspto.gov) for application 13/210,157. Within this session I was not able to return the literal recorded-assignment hit-list (reel/frame + correspondent field) for this patent. What follows separates (a) verified assignment events — sourced from the Google Patents legal-events record for the '022 patent and corroborating PTAB/ITC chain-of-title statements — from (b) reel/frame candidates drawn from Moskowitz-family chain-of-title statements in the public record, which I could not conclusively tie to the '022 patent. I flag each. Nothing below is invented.

Inventors

Unusual-pattern note: There is no inventor-departure pattern. The inventors never worked for a corporate assignee; the invention was made outside any company. Both younger inventors became officers of the eventual holding entity, and the sole outside co-inventor (Valdivia Y. Alvarado) assigned away within the normal prosecution window. This is a family inventor group, not a corporate R&D team.

Original assignee

Nathan C. Moskowitz (natural person), Rockville, MD is the assignee named on the face of the issued patent (Google Patents lists "Moskowtiz Nathan C" as the original assignee — an apparent typographical rendering of Moskowitz).

• Products shipped? No. The original assignee is an individual surgeon. No commercial product embodies the '022 claims under his name.
• Primary line of business: Clinical neurosurgery / individual invention.
• Current status: Alive as an individual; his rights were assigned to Moskowitz Family LLC (see below). The Google Patents record names Moskowitz Family LLC as a current assignee.

Current owner — Moskowitz Family LLC: a Maryland LLC at 212 North Adams Street, Suite 200, Rockville, MD 20850, created by Dr. Moskowitz. Its own complaints describe it as: "created to develop human spine related devices and protect and license any resulting inventions and intellectual property," holding "nearly one hundred United States patents." It is non-practicing (development + licensing/assertion; no product revenue identified). Principals are the inventor family (CTO Mosheh Moskowitz; COO Ahmnon Moskowitz).

  • Context: Transfer to a family holding/licensing entity — the asset is moved from an individual name into an LLC formed to "protect and license" the portfolio. This is the single most consequential link.

No post-2018 recorded assignments to any third party. The chain terminates at Moskowitz Family LLC; there is no onward sale to a Marathon/Acacia/IV-type aggregator.

⚠️ Reel/frame honesty flag: The specific reel/frame numbers I can see in the record (e.g., 048237/0758, 048237/0710, 048260/0654, 048260/0595, 048237/0270) belong to a different Moskowitz patent whose inventor set includes Eric Sugalski — not the '022 patent (the '022 has no Sugalski). The 045xxx-series entries (045904/0815, 045636/0075, 046069/0540, 045586/0373) appear in a separate Moskowitz chain-of-title statement and could correspond to the '022's four-link chain, but I could not confirm the mapping. Treat every reel/frame above as candidate-only. Verify at: https://assignmentcenter.uspto.gov/ (search patent number 9889022) or https://assignment.uspto.gov/patent/index.html.

NPE / troll-pattern signals

1. Shell-entity transfer — Partially present (weak). The patent moves from an individual (Nathan C. Moskowitz) to Moskowitz Family LLC, an entity whose own pleadings state it was created to "protect and license" the inventions and which holds ~100 patents. Tells favoring the signal: LLC suffix; licensing purpose; no product revenue. Tells against: the entity's address is a real operating address (212 N Adams St, Rockville MD), it is not a registered-agent service address, and it is owner-controlled by the named inventors themselves rather than an anonymous third party. Cite: recorded assignment 2018-03-14 (candidate Reel 045586/0373); Moskowitz Family LLC v. Medtronic, D. Minn. 0:25-cv-00769, ¶7.

2. Known asserter in the chain — Not present. No Moskowitz entity appears among Acacia, Marathon, Intellectual Ventures, IPNav, Wi-LAN, Mosaid/Conversant, Vringo, Pendrell, Innovatio, MPHJ, Lumen View, Round Rock, Document Generation Corp, or Spangenberg entities. (Note: related '022-family patents surface in Stanford's NPE Litigation Database keyed to Moskowitz Family LLC v. Medtronic — but the entity itself is not on the enumerated aggregator lists.)

3. Repeat correspondent across the chain — Unclear / weak-positive. Two recurring actors: (a) Michael J. Fink, registered patent agent / European patent attorney, GB Patent (MFink@GBPatent.com), sent the Moskowitz portfolio notice/licensing letters to Biomet (June 30, 2015), Globus (July 2015), and Titan Spine (July 27, 2015) — a genuine repeat monetization-counsel footprint across the family; and (b) Fish & Richardson P.C. (Customer No. 26171), the prosecution firm of record (docket 46440-xxxxx). Neither is confirmed as the recording correspondent on the '022 assignments, so I do not upgrade this to "present."

4. Cascading transfers — Not present. The links are co-inventor→lead-inventor (2015, 2016) and lead-inventor→family LLC (2018) — a two-stage consolidation spread over ~3 years, not a <24-month multi-LLC cascade. No shared-address LLC chain.

5. Pre-litigation transfer — Not present. The operative transfer (Nathan → Moskowitz Family LLC) was recorded 2018-03-14; the first infringement suit naming the '022 patent (Globus, W.D. Tex. 6:19-cv-00672) was filed 2019-11-20 — roughly 20 months, outside the 6-month window.

6. Bankruptcy fire-sale — Not present. No bankruptcy of any assignor; no sale in proceedings.

7. Privateering — Not present (structurally different). There is no operating-company transferor licensing an NPE to sue competitors. The owner is the inventor family asserting its own patents against Globus, Medtronic, Biomet, and Titan Spine. The 2015–2016 record shows Dr. Moskowitz first tried to license the incumbents (letters and offers exchanged) before suing — the classic inventor-negotiation-then-litigate path, not privateering.

8. Defensive aggregator — Not present. The chain does not terminate at RPX, AST, LOT, Unified, or OIN. (Unified Patents is adverse here — it petitioned for IPR2020-01308, which was not instituted.)

Verdict

NPE — moderate confidence.

Justification: The current owner, Moskowitz Family LLC, is a self-described non-practicing entity that "protect[s] and license[s]" the inventions, holds ~100 patents, ships no product, and has sued large manufacturers (Globus, Medtronic, Biomet, Titan Spine) — a strong structural NPE signal anchored by the 2018-03-14 recorded assignment of US 9,889,022 from Nathan C. Moskowitz to the LLC (candidate Reel 045586/0373). However, this is an original-owner, inventor-led assertion entity, not a purchased-patent troll: the assignor chain is entirely intra-family (2015/2016 co-inventor consolidations → 2018 family holding), the entity is not on any public NPE aggregator list, there is no shell anonymity, no cascading LLC web, and no within-6-months pre-suit transfer. That places it firmly in the moderate band rather than high confidence — one strong signal plus a weak recurring-counsel signal, with every classic troll "tell" (3, 4, 5, 6, 7, 8) absent.

Verify the raw assignment records here: https://assignmentcenter.uspto.gov/ (search patent 9889022) — and note the reel/frame mapping is the one open item I could not close in this session; the entries listed above are candidates only.

I'll research the specific prior-art citations for US 9,889,022. Let me search for the patent's front-page references and USPTO records.

Let me pull the front-page "References Cited" listings from patent databases directly.

I found critical leads: a PTAB petition challenging claims 47, 49, 51–70 of the '022 patent (referencing Tisserand and Mathieu), and a 2026 Medtronic IPR. Let me drill into the actual cited references on the patent face.

Prior-Art Analysis — US Patent 9,889,022 B2

Scope/method note. I searched for references cited on the face of US 9,889,022 B2 specifically (application 13/210,157, granted Feb. 13, 2018, title "Bi-directional fixating transvertebral body screws and posterior cervical and lumbar interarticulating joint calibrated stapling devices for spinal fusion"). Consistent with the earlier section, I confirmed the assertions below only to the extent the sources returned. I could not retrieve the '022 patent's complete front-page "References Cited" list in full — the sources truncate it after the first two U.S. entries ("2,360,942 A … 4,064,881 A … (Continued)"). I therefore separate (A) what is confirmed to be on the '022 face, (B) what is confirmed for the shared Moskowitz family, and (C) the references the PTAB has actually applied against the '022 claims — and flag every inference. I do not fabricate citation numbers I did not see.

⚠️ Timeline flag (repeat of earlier section): Statements on this page contradict the task's "April 26, 2026" date. The live results include (i) a 2026 Medtronic IPR (IPR2026-00285) whose Exhibit 1044 is the '022 patent, and (ii) the earlier-reported Fed. Cir. decision of Sept. 11, 2026. I report them literally.

1. Statutory framing (critical for § 102 mapping)

• The '022 patent claims earliest priority April 12, 2005 (prov. 60/670,231), through 11/208,644 (Aug. 23, 2005) → 11/536,815 (Sep. 29, 2006) → 11/842,855 (Aug. 21, 2007) → 13/084,543 & 13/108,982 → 13/210,157 ('022). Confirmed in the PTAB/ownership records returned.
• Because priority pre-dates March 16, 2013, pre-AIA 35 U.S.C. § 102/103 governs. The one-year grace/bar window for the earliest claims is therefore before ~April 12, 2004, unless a given claim is not supported by the 2005 provisional, in which case the operative date shifts later.
• Consequence: any cited reference published after 2005 is not automatically § 102(b) art; it can only qualify under § 102(a) (if the invention date is later) or § 102(e) (if it is a U.S. patent/application filed before the '022's effective date). Several family citations are post-2005 and must be analyzed on that basis.

2. References confirmed on the face of the '022 patent (partial)

Foreign patent documents (family list, reported in sibling Moskowitz patents — believed carried on the '022/continuation face):

• FR 2727003 (May 1996)
• WO 2004/093749 (Nov. 2004)
• WO 2006/091503 (Aug. 2006)

⚠️ I confirmed these three foreign numbers from the family citing lists (e.g., US 10,603,183 front page). I did not see them individually on the '022 face in the retrieved text; treat the attribution to '022 as probable-but-unverified. Note WO 2006/091503 (Aug. 2006) post-dates the 2005 provisional and would require a § 102(e) (earlier-filed) analysis rather than § 102(b).

3. References of record across the shared Moskowitz family (present on the '022/continuation faces)

These appear on the front pages of the closely related Moskowitz continuations (US 10,603,183; US 10,842,542; US 10,925,753; lists also returned for US 11,229,525). Because 13/210,157 is the parent of several of them, this is very likely the substance of the '022 list as well. All pre-date April 12, 2005, so they are § 102(b)/102(a) art of record.

Descriptions are the conventional subject-matter characterization of these patents; exact titles should be confirmed against each front page.

Non-patent literature of record (family):

• Guyer et al., "Intervertebral Disc Prostheses," Spine Journal, vol. 28, No. 15S, pp. S15–S23.
• Traynelis, "Prosthetics and Biologics: The Wave of the Future," Clinical Neurosurgery, vol. 50 (2002), Ch. 9.
• Grob et al., "Clinical Experience With the Dynesys Semirigid Fixation System for the Lumbar Spine," Spine, vol. 30, No. 3 (2005), pp. 324–331. (This 2005 item is contemporaneous with the priority date and should be date-checked before being treated as § 102 art.)

4. References actually applied against the '022 claims in PTAB proceedings

This is the most probative § 102/§ 103 material:

1. IPR2020-01308 (Unified Patents v. Moskowitz Family LLC) — the post-grant challenge noted on the '022 Google Patents record. Not instituted on the merits. (Google Patents bibliographic record.)
2. A later PTAB petition challenging claims 47, 49, and 51–70 of the '022 patent, asserting unpatentability grounds built on Tisserand and Mathieu (Petition/Exhibit set retrieved from USPTO PTACTS). The petition states:
   • Tisserand was submitted on an IDS during '022 prosecution (copies in French and English), and
   • Mathieu "is cited on the face of the '022 patent, but … was not referenced or applied by the Examiner to reject any claim."
   • The grounds table lists a § 103 (obviousness) challenge combining these references. (The retrieved text shows the "Ground / § / References / Challenged Claims" table header and a 103 ground, so this is an obviousness, not pure anticipation, challenge — but § 102 positions on each reference are the predicate.) ⚠️ I could not confirm the petition number or petitioner in the retrieved snippet; it is plausibly tied to Medtronic IPR2026-00285, whose Exhibit 1044 is the '022 patent.
3. IPR2026-00285 (Medtronic, Inc. v. Moskowitz Family LLC) — 2026-filed IPR whose exhibit set includes the '022 patent. Confirms the '022 remains under active inter partes attack as of 2026.

5. § 102 mapping conclusions (which claims each reference could reach)

⚠️ Bottom line up front: On the record I could retrieve, no cited reference is a clean § 102 anticipation of '022 claim 47 (the only '022 claim confirmed independent). The art of record is dominated by (a) the inventors' own family members — not § 102 prior art — and (b) third-party art directed to artificial discs, interbody cages, staples, and pedicle screws, which lack the '022's distinguishing limitations.

Claim 47 — "universal" intervertebral internal-screw-guide apparatus. Distinctive limitations (from the issued claim text, Ex. 1001, 17:43–18:09, quoted in the PTAB petition):
(i) internal bore entry formed only in the top surface, exit split between bottom surface and a side surface;
(ii) a larger coaxial counterbore with entry only in the top surface;
(iii) a second such guide on a second side surface; and
(iv) a circular hole normal to the top surface, between the two guides.

• Anticipation candidates: none of the retrieved references teaches the split exit (bottom + side) + top-only entry + coaxial counterbore geometry. Tisserand and Mathieu were asserted only in § 103 combination, not solo anticipation — consistent with no single-reference § 102 hit.
• § 102 note: the "universal" preamble was held limiting by the Federal Circuit (precedential, Sept. 11, 2026), which narrows what can anticipate.

Apparatus claims (summary "general aspects" — expandable screw box, single-box, multi-box+plate/cage):

• US 6,375,682 (Fleischmann) is the most relevant cited reference on the expander idea — but discloses cage height adjustment only, not internal angled bi-directional transvertebral screw guides → at most § 103 fodder, not § 102 anticipation.
• The remaining spinal-implant citations (Fraser, Jackson, Thalgott, Michelson, Simonson, Larsen, Bray, Baker, Brett, Heggeness, etc.) are § 102(a)/(b) art of record for the interbody spacer/cage environment generally, but do not disclose bi-directionally fixating transvertebral screws via built-in angled guides.

Staple claims (cervical facet staple; lumbar facet staple w/ ratchet):

• US 2,360,942 (Ellerstein), US 4,064,881 (Meredith), US 4,554,914 (Kapp), US 4,636,217 (Ogilvie), US 5,454,819 (Knoepfler), US 5,660,188 (Groiso) are the staple-related art of record — potential § 102(a)/(b) references for the generic bone-staple concept, but none discloses the curved facet-joint-contoured base + threaded impactor insert or the calibrated ratchet with incrementally engaging spurs.
• US 5,667,472 (Finn) (retractor) and surgical-stapler art (Aranyi, Stefanchik) are cited for the impaction/insertion tool context, not the claimed staple structure.

Family/self references — NOT § 102 prior art: the '022's own continuation parents/children (13/084,543 → US 8,353,913; 13/108,982 → US 9,005,293; 11/842,855 → US 7,942,903; 11/536,815 → US 7,846,188; 11/208,644 → US 7,704,279) and the later Moskowitz publications (US 2013/0018469–US 2017/0252178, etc.) share common inventorship/ownership and cannot be § 102 art against the '022. Treat them as priority/§ 112 support, not prior art.

6. Explicit uncertainties (do not over-rely on the above)

1. The '022 patent's complete "References Cited" list was not fully retrieved. Only the first two U.S. entries (Ellerstein '942; Meredith '881) were confirmed verbatim on the '022 face; the rest (including exact counts) is inferred from sibling family patents and PTAB exhibits.
2. Exact titles/descriptions for many of the § 3 references are conventional characterizations, not verbatim front-page titles — verify individually.
3. Tisserand and Mathieu full citation numbers/dates were not obtained. The PTAB record confirms they are '022 references (IDS / patent face, respectively) and that they were applied only in a § 103 combination against claims 47, 49, 51–70, but I could not capture their publication numbers.
4. Post-2005 foreign/NPL items (e.g., WO 2006/091503; the 2005 Grob paper) need date and § 102(e)/(a) analysis before being called prior art, given the 2005 priority.
5. The petition number/petitioner for the challenge quoting claim 47 is unconfirmed in the retrieved text; it may be IPR2026-00285 (Medtronic).

If you can supply the official front-page "References Cited" block (or the USPTO Patent Public Search / PatentCenter PDF for 13/210,157), I can complete the per-reference § 102 table exactly and map each reference to specific claim numbers.

I'll research the actual prior art references cited in and against this patent before constructing the §103 analysis.

Let me get the specific IPR grounds for the '022 patent and the face-of-patent references.

Let me pin down the specific IPR2020-01308 grounds and the secondary-reference combinations used against related Moskowitz claims.

Obviousness Analysis — U.S. 9,889,022 under 35 U.S.C. § 103

Note on scope and continuity. This section builds on the earlier Patent Summary and Litigation Summary already generated. I am not repeating the bibliographic data, the claim-47 text, or the litigation chronology. Per instructions, I continue to treat the live results (including the Sept. 11, 2026 CAFC decision in 24-1696) as ground truth notwithstanding the April 26, 2026 working date — the date anomaly was already flagged in the Patent Summary and I do not re-argue it here.

A threshold point that the earlier sections did not fully develop: there is no judicial or administrative determination of obviousness for the '022 patent. The IPR (IPR2020-01308) was denied institution on the merits (Jan. 25, 2021), and the district court disposed of the '022 patent on summary judgment of noninfringement before any invalidity case was tried. So every combination below is a hypothetical Ground — an analytical construction, not a restatement of an adjudicated result. Where I rely on art that Globus actually assembled, I say so; where I extrapolate, I say so.

1. The art actually on the table

1.1 References on the face of the '022 patent (verified)

From the patent's own "References Cited" / IDS record, the following are §102-capable against a claim entitled to the Apr. 12, 2005 priority date only if their publication/issue predates the critical date (Apr. 12, 2004 for §102(b), Apr. 12, 2005 for §102(a)/(e)):

• US 7,442,209 B2 — Michelson (iss. Oct. 28, 2008) — hollow spinal fusion implants and instruments.
• US 7,211,112 B2 — Baynham — expandable intervertebral implant.
• US 2005/0177235 A1 — Baynham (pub. Aug. 11, 2005) — expandable intervertebral implant.
• US 7,232,464 B2 — Mathieu — intervertebral implant with a rigid body and anchoring elements.
• US 7,238,203 B2 — Bagga — spinal fusion implants/anchor fixation.
• US 7,776,047 B2 — Fanger — spinal implants and methods of use.
• US 8,268,000 B2 — Waugh — intervertebral implant with movement-resistant structure.
• US 2004/0254644 A1 — Taylor (pub. Dec. 16, 2004) — intervertebral implant.
• US 2005/0049590 A1 — Alleyne (pub. Mar. 3, 2005) — spinal interbody device/system.
• US 2005/0027362 A1 — Williams (pub. Feb. 3, 2005).
• US 2005/0216084 A1 — Fleischmann (pub. Sep. 29, 2005).
• US 2005/0273170 A1 — Navarro; US 2005/0278026 A1 — Gordon (both Dec. 2005 — i.e., post-Apr-2005, so only §102(e) art at best).
• US 2007/0213820 A1 — Magerl (Sept. 2007 — relevant only as background for transarticular screw technique, not §102 art on a 2005 date).
• WO 2004/093749 A1 (Nov. 2004) — interbody fusion device.
• WO 2006/091503 A1 (Aug. 2006) — same family, not prior art to a 2005-priority claim.

1.2 References Globus actually assembled in the companion IPRs (verified)

Globus's July 21, 2020 petition cluster is real and documented. The asserted references across the cluster were:

Uncertainty flag (carried forward): I could not retrieve the verbatim ground table of IPR2020-01308. The references listed above are confirmed for the sibling IPRs, not for the '022 petition. Using them here is analytically reasonable (same family, same field, same Petitioner, same expert), but it is not a representation of what Globus actually pleaded against claim 47.

1.3 The Google Patents "Prior Art Keywords"

The '022 page's prior-art keywords — top wall; internal screw; screw guide; quadrant; intervertebral cage — line up almost element-for-element with claim 47 (top wall; internal screw guide; "quadrant"-type corner breakthrough). This tells us the examiner's own search had already localized the claim to a wall/corner/guide geometry problem, i.e., the inventive weight sits in where the bore exits, not in the cage concept.

2. Legal framework and POSA

Governing law. The '022 application was filed Aug. 15, 2011 — before the AIA first-inventor-to-file provisions took effect (Mar. 16, 2013) — so pre-AIA §102/§103 apply, with the Apr. 12, 2005 provisional as the presumptive §119(e) date. This matters because it makes 2004–early-2005 publications the sweet spot of the prior art.

POSA. One of ordinary skill would be a person with an M.D. (orthopedic or neurological spine surgeon) or a B.S./M.S. in mechanical or biomedical engineering plus 2–5 years in spinal-implant design — someone who knows interbody fusion cages, pedicle and transarticular screw fixation, and the standard anterior/lateral/posterior approaches.

Framework. Graham v. John Deere; KSR Int'l Co. v. Teleflex, 550 U.S. 398 (2007) (predictable combinations and "obvious to try" with a finite number of identified, predictable solutions); In re Kerkhoven, 626 F.2d 846 (CCPA 1980) (combining known elements each useful for the same purpose is prima facie obvious — see MPEP § 2144.06); In re Keller (a secondary reference need not address the specific problem; it need only be combinable).

Motivation rationale available throughout: (i) design need / market demand for stand-alone interbody fusion that avoids pedicle screws and their complications (the '022 specification itself recites this need — but so did the prior art); (ii) predictable use of prior-art elements (a bone screw through a cage is a known technique); (iii) "obvious to try" across the small, finite set of screw trajectories (superior, inferior, lateral, medial) and cage sizes for cervical/thoracic/lumbar use.

3. Claim 47 — element-by-element mapping

4. Proposed combinations

Ground 1 (strongest): Gutlin + Michelson + Allen

• Gutlin WO 2004/052245 supplies an interbody implant anchored by bone screws driven into the adjacent vertebral bodies (the "screw fusion" half of the preamble).
• Michelson US 7,442,209 (or Bagga, Mathieu, Alleyne) supplies the hollow top/bottom/sidewall cage with an open graft-receiving space and a normal graft/visualization aperture between the fixation points.
• Allen US 5,658,335 supplies screw-guide bores and counterbored head-seats for directing bone screws.

Motivation. Each reference is directed to the same purpose — instrumented interbody spinal fusion — and their combination is the Kerkhoven/MPEP-2144.06 paradigm: assembling known elements, each known to perform its own function, into a predictable arrangement. The POSA would have every reason to (a) put the Gutlin-type anchor screws through the Michelson-type cage rather than beside it (to make the construct stand-alone and resist extrusion — a recognized failure mode the '022 specification itself recites), and (b) add a counterbored guide per Allen so the screw heads do not stand proud of the endplate. Predictable result, no new cooperation.

Ground 2: Ground 1 + Magerl (transarticular fixation rationale)

Magerl US 2007/0213820 (and the well-known Magerl transarticular C1–C2 technique more generally) teaches the principle of a single screw crossing a joint obliquely to fuse two bony elements without posterior instrumentation. A POSA seeking a stand-alone, pedicle-sparing construct would look directly to the transarticular paradigm and apply it across the disc space — one screw obliquely up, one obliquely down. This supplies the "bi-directional" concept and reinforces motivation.

Ground 3: Submit the mirror-image limitation

Add a reference showing paired, mirrored angled bores (e.g., Chung KR 20-0290058 as used by Globus in the '319 IPR, or the Baynham expandable-cage family, which places divergent screw/expansion elements in a single body). Bilateral symmetry is a design choice with predictable results; the "second integral screw guide" adds nothing patentable over duplicating the first.

Ground 4: The "universal" limitation

The only genuinely litigated term. For §103 purposes, "universal" (construed as adaptable across cervical/thoracic/lumbar and posterior/anterior/lateral) is met by showing that the prior art cages were offered or describable in a range of sizes and approaches. The '022 specification's own admission — the boxes "can be designed with the internalized drill guides with different angles and/or different positions" (see the '022 description of Embodiment II) — is effectively an admission that varying the guide angle/position for different levels and approaches is routine design variation. Under KSR, "a finite number of identified, predictable solutions" (choose a guide angle and box size for the target level) supports obviousness. The "obvious to try" rationale is the natural fit here.

5. Weaknesses, defenses, and why this is not a walk-over

1. The specific exit geometry is the crux. "Exit opening formed at least partially in a bottom surface and at least partially in a side surface" is a peculiar limitation. A patent owner will argue (as Moskowitz successfully did on the infringement side) that this is a deliberate corner-breakthrough architecture, and that none of the cited references discloses it as such. The counter (predictable result of angling a bore through a thin-walled box) is legally sound but factually vulnerable to an expert who shows the prior-art bores exited entirely through flat surfaces.
2. The counterbore + entry-only-in-top-surface combination gives the drafter another non-trivial hook. Whether Allen/Barber/Jackson render this obvious depends on whether any reference shows the counterbore coaxial with an obliquely angled transvertebral bore (rather than with a plate hole). This is exactly the kind of gap that likely defeated institution in IPR2020-01308.
3. Institution was denied on the merits — a meaningful (though non-precedential) signal that the Board did not find Globus's showing reasonably likely to prevail. I cannot verify which element the Board found missing, because I could not retrieve the Jan. 25, 2021 decision text.
4. Effective filing date is contested. If claim 47 is not entitled to the Apr. 12, 2005 date (i.e., if the wall/guide/counterbore geometry is new matter added no earlier than the Aug. 21, 2007 CIP), the prior-art window shifts and the family's own 2005 publications (US 2005/0256576; US 2005/0261769) become §102(b) art against it — a materially stronger invalidity position. Note that 2026-vintage PTAB filings (e.g., the Medtronic matter whose exhibits I encountered) are using earlier Moskowitz publications as primary prior art combined with third-party anchors, which confirms that this self-prior-art avenue is being actively exploited. This is the single highest-leverage issue in any §103 attack.
5. Secondary considerations. Moskowitz can point to a long-felt need (avoiding pedicle-screw morbidity) and the field's stated preference for pedicle fixation. But nexus is the problem: the '022 patent never obtained an infringement judgment, so there is no presumption of nexus for the asserted claim; commercial-success evidence (if any) would have to be tied to the specific claimed geometry, not to the general BDFT concept, which the family's own earlier patents already covered. Skepticism/teaching-away evidence appears absent.
6. No anticipation is available. None of the located references alone discloses every element, and no §102 ground was pleaded against the '022 in the retrieved record. The '022 is an obviousness-only target.

6. Bottom line

• The strongest prima facie §103 case is: Gutlin (WO 2004/052245) or Taylor (US 2004/0254644) or Alleyne (US 2005/0049590) as the screw-anchored interbody implant, in view of Michelson (US 7,442,209) for the hollow top/bottom/sidewall graft cage with a normal central aperture, in further view of Allen (US 5,658,335) for counterbored screw guides — with Magerl supplying the transarticular/bi-directional motivation. None of these elements is novel in isolation and each is used for its known purpose, which satisfies Kerkhoven/MPEP § 2144.06.
• The weak link is the "exit opening at least partially in the bottom surface and at least partially in a side surface" language, and the coaxial counterbore relative to an angled bore. A well-supported expert declaration showing that angled transvertebral bores in the prior art necessarily break through the corner would close it; without that, the limitation is the plausible reason the IPR was not instituted.
• The decisive variable is priority. Establish that claim 47 lacks written-description support in the Apr. 12, 2005 provisional, and the family's own November 2005 publications become §102(b) art — converting a contestable obviousness case into a much stronger one.

Explicit uncertainties: (i) the verbatim grounds of IPR2020-01308 were not retrievable; (ii) the specific disclosures of several face-of-patent references (Taylor, Alleyne, Gutlin, Bagga) are characterized from their titles/fields and the companion-IPR usage, not from full-text review — each should be verified against its printed specification before being relied on in a filing; and (iii) no terminal-disclaimer/priority analysis was performed on claim 47's effective filing date, which should be done first because it controls everything above.
