Patent landscape map & filable white space

Computational scan of public-domain patent and patent-application disclosures across the chemistry, mechanism, and delivery axes surfaced by WP1–WP5. Identifies open claim space and FTO landmines for the recommended retina-first program and the KAT8 long-bet.

Computational research use only — not clinical, not therapeutic, not wet-lab instruction.

★ WP7 Headline

The KAT8/MOF axis is the cleanest filable white space identified by RIA-01. The combination architecture (priming chemistry + AAV-OSK pulse + maintenance chemistry) is filable as a method-of-use claim even where individual components are heavily patented. Tazemetostat composition claims are locked by Epizyme, but reprogramming-specific method-of-use claims for Tazemetostat have not been disclosed to RIA-01's search date.

Cross-walks cleanly into Atlas Bio's existing IP base — U.S. Provisional 63/986,270 (filed Feb 19, 2026, capsid intelligence platform). A second provisional cluster on the reprogramming methodology is the recommended path for counsel evaluation.

1. Search method & limitations

RIA-01 surveyed public-domain patent disclosures via Google Patents, USPTO PAIR, EPO Espacenet, and WIPO PATENTSCOPE indices using keyword combinations: "MOF" / "KAT8" / "MYST1" + "small molecule"; "H4K16ac" + "aging"; "partial reprogramming" + method; "Yamanaka factor" + "AAV"; "Tazemetostat" + "epigenetic"; "tet enzyme" + "reprogramming"; "epigenetic clock" + "reversal". The search is intentionally surface-level and excludes Chinese-language filings, machine-translated regional applications, and recently-filed applications under 18-month publication delay.

H4K16ac restoration methods for agingPatchy academic; no biotech method-of-use franchise—OPEN — method-of-use white space
FILABLE WHITE SPACE (HEADLINE)
The KAT8 / H4K16ac axis is the cleanest IP white space in the entire RIA-01 study. Composition-of-matter claims on a novel KAT8 activator chemotype, plus method-of-use claims on H4K16ac-restoration for aging endpoints, plus combination claims with AAV-OSK delivery would represent first-in-class IP with no obvious blocking prior art. This is exactly the kind of filable position that justifies a dedicated provisional cluster.

2D — EZH2 inhibitors (Tazemetostat & class)

Patent familyAssigneeScopeStatus
Tazemetostat (EPZ-6438) compositionEpizyme (now Ipsen)EPZ-6438 chemical composition; method-of-use in EZH2-mutant lymphoma and epithelioid sarcomaCROWDED — composition locked; oncology use locked

Tazemetostat / EZH2-i method-of-use in partial reprogramming / agingNONE IDENTIFIED—OPEN — reprogramming-specific use claims appear unclaimed
EZH2-i + AAV-OSK combination methodsNONE IDENTIFIED—OPEN
FILABLE WHITE SPACE
A method-of-use claim for Tazemetostat (or selective EZH2-i more broadly) specifically in partial cellular reprogramming maintenance appears to be filable. Composition is blocked; use in oncology is blocked; aging/reprogramming use is not. Counsel scrutiny required — this is the kind of claim that Epizyme/Ipsen might also seek, so timing is sensitive.

2G — Sinclair-lab IP cluster (cross-cutting)

David Sinclair (Harvard) and affiliated entities (Life Biosciences, Iduna Therapeutics, Tally Health) hold a substantial patent cluster across aging-clock methodology, OSK delivery for vision, and chemical reprogramming. RIA-01 surfaces this as a meta-landscape factor: any Atlas Bio program in the retina-first or aging-clock space should anticipate proximity to Sinclair-cluster filings. Counsel-led patent-family-pendency check is essential.

Density % is RIA-01's qualitative estimate of how crowded each lane is with filed-and-issued patents plus published applications. The top six lanes (KAT8 activator, NSL/MSL stabilizers, H4K16ac restoration methods, Tazemetostat reprogramming use, EZH2-i+OSK combinations, 3-phase architecture) are the principal P0/P1 filable targets — bundled into Cluster A–C in section 5 below.

Counsel priority is RIA-01's directional flag, NOT a filing instruction. P0 = recommend counsel review within 30 days. P1 = within 90 days. P2 = within next budget cycle.

5. Recommended provisional-filing clusters (for counsel evaluation)

P0 Cluster A — KAT8 / H4K16ac axis

Working title: "Compositions and methods for restoring H4K16 acetylation in age-associated indications"

Composition-of-matter claims on KAT8 activators or NSL/MSL complex stabilizers (when WP2.1 Strategy 1 produces a tool); method-of-use claims for H4K16ac restoration in retina, CNS, and other tissue-targeted reprogramming contexts; combination claims with AAV-OSK delivery. Timing: ideally before any public disclosure of the WP-final white paper.

P0 Cluster B — Retina-first three-phase architecture

Working title: "Methods of partial cellular reprogramming via small-molecule priming, AAV-mediated transcription factor delivery, and selective epigenetic maintenance"

Combination method-of-use covering the priming → pulse → maintenance architecture; specific Vit C + α-KG → AAV-OSK → Tazemetostat combination claims; tissue-restricted retina/CNS embodiments. Timing: before publication of the retina-first program design.

P0 Cluster C — Tazemetostat reprogramming method-of-use

Working title: "Methods of using EZH2 inhibitors to maintain epigenetic reprogramming states"

Method-of-use claims for Tazemetostat (and selective EZH2-i more broadly) specifically in cyclic / pulsed reprogramming maintenance; combinations with OSK delivery; dose schedules separate from approved oncology use. Timing-sensitive: Epizyme/Ipsen could also file in this space.

P1 Cluster D — Re-dosable engineered AAV (extension of 63/986,270)

Working title: "Engineered AAV capsids with reduced humoral immunity for repeat administration"

Continuation-in-part or new provisional extending Atlas Bio's existing capsid intelligence platform IP into surface-modified, immune-evading variants suitable for cyclic delivery. Natural extension of 63/986,270. Timing: coordinate with existing patent prosecution.

P1 Cluster E — RIA-01 methodology (jurisdiction-dependent)

Working title: "Computational systems and methods for cellular-reprogramming candidate scoring and white-space identification"

Software / method claims on the AI-agent scoring methodology. Jurisdiction-dependent (US software patentability post-Alice; EU software patent restrictions). May be more appropriate as trade secret + copyright on the agent prime directive than as patent. Counsel call.

6. Freedom-to-operate (FTO) landmines for the retina-first program

ComponentBlocking IP holderMitigation path
4D-R100 retinal capsid 4D Molecular Therapeutics Partnership / license / co-development — same path as the existing 4DMT case study
AAV9 serotype UPenn / Penn Vector Core Standard AAV9 license terms; commercial use defined
PHP.eB engineered capsid Caltech (Gradinaru / Deverman) License or substitute with platform-derived BBB-capable variant from Atlas Bio's existing engineering pipeline
Tazemetostat composition Epizyme / Ipsen License required for commercial use; off-label investigator-initiated study path; alternatively use a GSK126 or other selective EZH2-i if separable IP path
OSK / OSKM factors Kyoto Univ / iPS Academia Japan; multiple later filings Reduced-factor cassettes (OS only; or OSK with specific stoichiometries) may be filable around base patents; counsel review
Aging-clock methods (Horvath, GrimAge, DunedinPACE) UCLA; Duke Commercial license for endpoint use in trials; some clocks have research-use exceptions
AAV-OSK retinal delivery method Harvard / Sinclair-affiliated Hardest landmine. Combination embodiments with the priming + maintenance layers may distinguish; counsel-led claim chart essential

KAT8 / H4K16ac restoration methodsAlmost certainly not covered (different mechanistic axis)Cluster A is a new family
Tazemetostat method-of-useNot coveredCluster C is a new family

8. File-before-publish discipline (timing)

The single most important timing principle for the WP-final synthesis and any subsequent publications:

DO NOT PUBLICLY DISCLOSE BEFORE PROVISIONALS ARE ON FILE
The WP-final synthesis white paper, the KAT8 gap finding, the retina-first program design, and the Tazemetostat reprogramming-use observation are all public-disclosure events under US (1-year grace period) and EU/PCT (no grace) patent law. Disclosure before provisional filing materially weakens the IP position.

Recommended timing sequence (for counsel finalization)

  1. Counsel review of Clusters A, B, C within 30 days of WP-final completion.
  2. Provisional filings (or formal trade-secret declarations) before any external sharing of the WP-final synthesis.
  3. 12-month PCT clock from provisional filing date controls international filing window.
  4. Preprint (bioRxiv) and peer-reviewed publication only after provisionals on file.
  5. Investor briefings: redacted versions before filing; full versions after filing.

9. Open questions for WP7.2 or counsel
