Two rankings
The package separates unique holder rank from grant rank. Blair and Rillieux each appear more than once in the grant sequence.
A source-led CultureUp hub for reading Black American patent holders as public-record memory: invention, property, place, citizenship, labor, and recognition across the federal U.S. patent era.
Method
A patent can show legal inventorship, place, date, title, and sometimes assignment. It cannot by itself prove full biography, community standing, lineage, economic return, or all the technical labor behind an invention.
The package separates unique holder rank from grant rank. Blair and Rillieux each appear more than once in the grant sequence.
Early claims use surviving-record language because the 1836 Patent Office fire damaged the X-patent archive.
CultureUp does not collapse Black American, African American, Creole, immigrant, or Indigenous Black identity into one label without a source trail.
Why patents belong here
CultureUp reads patents as records of legal recognition, skilled work, place, property capacity, institutional access, and source gaps. The archive is useful only when the proof and the limits stay visible together.
A patent can show a named inventor, date, title, residence, and public legal recognition. It should not be treated as a full biography or a complete technical-labor history.
New York, Glen Ross, New Orleans, and West Windsor are not incidental details. They attach invention memory to migration, land, skilled trade, agriculture, industry, and household work.
The damaged X-patent archive, race-data gaps, and unstable first-claim traditions are not footnotes. They explain why CultureUp uses careful surviving-record language.
How to read this archive
Each public card shows what the reviewed source trail can support today. Under-review claims stay visible without being promoted into sitemap-indexable profiles.
Grant rank counts patent grants. Unique-holder rank counts people. Repeat patentees appear more than once in the grant sequence.
Look for patent number, patent title, issue date, place, source grade, and whether the record is an X-patent or later utility patent.
A source may support a patent number without supporting biography, identity, ownership, commercial success, or lineage.
If a stronger public source changes a date, person, title, or sequence claim, CultureUp should update the source trail instead of stretching the current record.
Chronological holder cards
These are the first three profile routes in the package. They stay separated from later additions so CultureUp does not blur the public launch sequence with the next expansion lane.
New York, New York
Jennings belongs at the start of this CultureUp patent trail because the public source record ties his 1821 dry-scouring patent to free Black citizenship, skilled trade, abolitionist work, and the damaged X-patent archive.
Glen Ross, Montgomery County, Maryland
Blair's seed-planter and cotton-planter patents show Black agricultural invention entering the federal patent record before the Civil War, while also exposing how rarely the record marked race directly.
New Orleans, Louisiana
Rillieux's patent trail belongs in a Black patent archive because it shows early Black participation in U.S. industrial chemistry, while requiring careful Louisiana Creole identity language.
Next ten records
This expansion adds the next patent-holder profiles with defensible public source trails, while keeping Henry Lee and Samuel R. Scottron in noindex source review until their record conflicts are resolved.
After Jennings, Blair, and Rillieux, the next public records move through domestic technology, agriculture, public safety, rail infrastructure, and Black women's patent memory. CultureUp treats each row as a source-controlled patent record first, not as private lineage proof or unsupported first-language.
West Windsor, New Jersey
Hawkins enters this package as a patent-record page first: a West Windsor inventor whose 1845 gridiron patent shows domestic and culinary technology in the antebellum Black patent trail.
Albany, New York
Deitz enters the Reconstruction-era sequence through an Albany shoe patent, with the spelling variant preserved instead of hidden.
Amelia County, Virginia
Jones moves the patent archive into Black women's patent history and agricultural machinery through an 1868 Amelia County record.
Albany, New York
Elkins enters the Albany patent-memory cluster through a domestic labor-saving invention issued in 1870.
Dowagiac, Michigan
Martin brings the next-ten sequence into public safety through an 1872 fire-extinguisher improvement tied to Dowagiac, Michigan.
Ypsilanti, Michigan
McCoy's first patent profile starts with steam-engine lubrication, rail infrastructure, and industrial labor rather than phrase folklore.
Baltimore, Maryland
De Leon extends the Black women inventors and domestic technology lanes through an 1873 Baltimore cooking-apparatus patent.
Somerville / Salem, Massachusetts
Latimer's first CultureUp patent profile starts chronologically with his 1874 railroad-car water-closet patent, co-invented with Charles W. Brown.
Backlog 3
This backlog extends Patented Memory beyond the first public-release sequence and the Reconstruction-era next-ten sprint.
This backlog extends Patented Memory beyond the first public-release sequence and the Reconstruction-era next-ten sprint. These profiles move the archive into shoe machinery, steam-boiler furnaces, domestic technology, furniture, elevators, signal systems, ironing boards, public safety, Black beauty enterprise, and modern medicine.
These entries are not a claim that every chronological gap has been closed. They are the next source-led profiles CultureUp is preparing. Public ranks will be revised only when patent records, identity evidence, name variants, residence conflicts, and source limits are reconciled.
Lynn, Massachusetts
Matzeliger's 1883 lasting-machine patent moves Patented Memory into shoe machinery and industrial labor, with careful Suriname-born, U.S.-based identity language.
Cincinnati, Ohio
Woods enters Backlog 3 through an 1884 Cincinnati steam-boiler furnace patent, before later profiles expand his broader electrical and rail patent memory.
Washington, D.C.
Reed's 1884 dough kneader and roller patent belongs in the Backlog 3 public-record layer with biography and first-language kept carefully caveated.
Chicago, Illinois
Goode's 1885 cabinet-bed patent anchors a furniture and domestic-technology profile while CultureUp keeps first-language and business claims source-led.
Scaling Sprint 4
This sprint strengthens the bridge between the early Reconstruction-era sequence and the later major inventor profiles.
This sprint strengthens the bridge between the early Reconstruction-era sequence and the later major inventor profiles. It adds patent-record candidates in food tools, fire safety, writing tools, hair care, landscape machinery, rail safety, and sport. These entries are not final rank corrections until CultureUp reconciles identity evidence, name variants, residences, source limits, and patent records.
Oakland, California
Ashbourne's 1875 biscuit-cutter patent is a chronology-gap candidate in domestic food tools and baking technology, held noindex until identity evidence is ledgered.
Chambersburg, Pennsylvania
Winters's 1878 fire-escape ladder patent is a public-safety chronology-gap candidate held noindex while name/OCR and identity evidence are reconciled.
Cincinnati, Ohio
Johnson's 1884 egg-beater patent is a kitchen-labor chronology-gap candidate held noindex until identity evidence is ledgered.
Philadelphia, Pennsylvania
Purvis's 1890 fountain-pen patent is a writing-tools chronology-gap candidate held noindex until identity evidence is ledgered.
Scaling Sprint 5
This sprint adds systems-era and modern anchor profiles without converting them into final chronology rank corrections.
Sprint 5 moves Patented Memory into home heating, agricultural chemistry, mobile refrigeration, electronics, audio, home safety, optical transmission, space-science instrumentation, and commercialization. The cards preserve co-inventors and assignees where the patent records name them, because inventor, employer, assignee, licensee, and beneficiary are different public-record facts.
Morristown, New Jersey
Parker's 1919 heating-furnace patent lets CultureUp read domestic heating as a twentieth-century systems record without turning the patent into adoption or commercialization proof.
Tuskegee, Alabama
Carver's paint-and-stain patent belongs in Patented Memory as agricultural chemistry and materials work, not as a generic famous-inventor shortcut.
Minneapolis, Minnesota
Jones's vehicle air-conditioning patent belongs in CultureUp's systems lane because it connects mobile refrigeration, co-invention, corporate assignment, and public logistics memory.
Washington, District of Columbia
Kenner belongs in the health and home-accessibility queue, but CultureUp keeps the route noindex until the sanitary-belt primary patent trail is reconciled.
Scaling Sprint 6
This sprint adds advanced science and networked-systems profiles while preserving co-inventor, assignee, employer, and source-review discipline.
Sprint 6 expands Patented Memory into deeper twentieth-century and modern systems: food preservation, industrial chemistry, steroid recovery, assistive technology, gamma-electric power and detection, bioluminescence, electrogasdynamics, polymer materials, microcomputer architecture, EEO compliance software, and VoIP network performance.
Chicago, Illinois
Hall's profile reads food chemistry and industrial chemistry through patent records that name co-inventors and corporate assignees, not as a solo folklore shortcut.
Chicago, Illinois
Julian's route treats soybean sterols, industrial chemistry, and medicine-adjacent materials as a source-led patent record with Glidden assignment and co-inventor credit visible.
Newark, New Jersey
Blount Griffin's profile centers assistive technology and patient agency through a portable receptacle support patent while holding broader self-feeding claims to source review.
Urbana, Illinois
Sampson's profile reads the gamma-electric cell as a nuclear/electrical systems record with George H. Miley preserved as co-inventor and solar-cell claims kept out.
Backfill Sprint 7
This sprint fills everyday-infrastructure gaps with domestic labor, food service, child mobility, Black enterprise, and personal-care patent records.
Sprint 7 is a backfill layer, not a final chronological-rank rewrite. It makes common tools, care work, food systems, movement, and enterprise visible while keeping patent facts separate from identity, ownership, commercialization, and impact claims.
Washington, District of Columbia
Bailey's combined truss and bandage record belongs in an everyday health-support lane, but the route stays noindex until the name/OCR trail and identity source are reconciled.
Baltimore, Maryland
Richardson's child-carriage record moves Patented Memory into caregiving mobility, attendant labor, city movement, and assignment records with source limits visible.
Newark, New Jersey
Stanard's route reads compact cooking, food storage, buffet-car service, and cold-air circulation through two patent rows while preserving the Stanard spelling.
Dayton, Ohio
Sampson's clothes-drier record belongs in domestic labor history: drying frames, stove heat, smoke/fire risk, and household technology without absolute-first overclaiming.
Backfill Sprint 8
This sprint adds print, paper, doors, street rail, mail, music, barber-service, office-calculation, and recovery-work lanes while preserving identity review and source limits.
Sprint 8 is a public-tools and recovery-work layer, not a final chronological-rank rewrite. It makes civic infrastructure visible: printing presses, paper receptacles, door-holding devices, street-rail switches, pencil sharpeners, musical instruments, shampoo head-rests, office-calculation files, and the Baker/Murray recovery trail that explains why Black patent history has to be reconstructed.
Downing and Love are promoted as source-led Sprint 8 profiles because their attached rows are strong enough for public reading. Lavalette, Dorsey, Flemming, Brown, Bailiff, Baker, and Davidson stay noindex,follow until identity evidence, exact title records, or patent-family reconciliation is complete.
Washington, District of Columbia
Lavalette's printing-press patent belongs in the public-record tools lane, but the route stays noindex until identity evidence and promotion language are reconciled.
Washington, District of Columbia
Dorsey's door-holding device belongs in a public-buildings and access-tools lane, but CultureUp keeps it noindex and refuses the doorknob myth shorthand.
Source review pending
Flemming's musical-instrument patent can support a cultural-tools route only if CultureUp preserves the Euphonica title and refuses guitar-invention shorthand.
Source review pending
Brown's receptacle-for-papers patent belongs in the print, paper, and recordkeeping lane, but identity and biography claims remain under review.
Grant sequence
This hub shows a curated preview. Use the timeline and source ledger for the broader row-by-row record without turning the front page into a heavy data dump.
Thomas L. Jennings / 1821-03-03
Earliest currently verified Black American patentee in the reviewed public source trail; original X-patent specification remains unrecovered.
Henry Blair / 1834-10-14
Early Black agricultural patent record; public transcription notes legibility gaps and should be paired with images for deeper archive work.
Henry Blair / 1836-08-31
Second known Blair patent; grant rank differs from holder rank because Blair appears more than once.
Norbert Rillieux / 1846-12-10
NARA case-file context strengthens the public source trail for Rillieux's sugar-making improvements.
William A. Lavalette / 1878-09-17
Sprint 8 identity-review record. The patent row supports printing-press facts, but identity evidence is required before indexable promotion.
Osbourn Dorsey / 1878-12-10
Sprint 8 myth-resistance record. Use the patent title, door-holding device, not a broad doorknob claim.
Robert F. Flemming Jr. / 1886-03-30
Sprint 8 source-review record. The musical-instrument and Euphonica title trail requires reconciliation before promotion.
Henry Brown / 1886-11-02
Sprint 8 identity-review record. Treat as recordkeeping and paper-security infrastructure until public identity evidence is ledgered.
Philip B. Downing / 1890-06-17
Sprint 8 civic-systems candidate. This row supports a street-railway switch; the letter-box/mailbox claim remains source review until exact row reconciliation.
George Washington Murray / 1894-04-10
Sprint 7 backfill record. Murray is both a patent holder and a public-memory actor in the Baker/Murray recovery trail.
John Lee Love / 1895-07-09
Sprint 8 public-tools candidate. The plasterer's hawk row supports trade-tool memory and portable work systems.
John Lee Love / 1897-11-23
Sprint 8 public-tools candidate. The pencil-sharpener row supports desk, office, paperweight, and writing-infrastructure memory.
Charles Orren Bailiff / 1898-10-11
Sprint 8 identity-review record. The patent supports barber/service equipment facts, but identity evidence is required before promotion.
Charles S. L. Baker / 1900-01-01
Sprint 8 source-review placeholder. Exact friction-heater patent rows are required before promotion.
Shelby J. Davidson / 1910-01-01
Sprint 8 source-review placeholder. Exact adding-machine and tabulating-device patent rows are required before promotion.
George Washington Carver / 1925-06-09
Sprint 5 systems-era candidate. Patent and public-archive context support Carver's materials work; commercial, educational, and agricultural-extension claims require separate sources.
Percy L. Julian / 1942-02-17
Sprint 6 advanced science record. The patent row preserves John Wayne Cole as co-inventor and The Glidden Company as assignee.
Frederick McKinley Jones / 1942-12-01
Sprint 5 systems-era candidate. The record must preserve Joseph A. Numero as co-inventor and U.S. Thermo Control Co. as assignee.
James E. West / 1964-01-14
Sprint 5 modern systems candidate. The page must preserve Gerhard M. Sessler as co-inventor and Bell Telephone Laboratories as assignee.
George R. Carruthers / 1969-11-11
Sprint 5 modern systems candidate. The patent row supports image-converter facts and the federal assignee; Apollo and NASA memory require separate public context sources.
Marie Van Brittan Brown / 1969-12-02
Sprint 5 modern systems candidate. The record preserves Albert L. Brown as co-inventor and does not turn the patent into a complete history of modern surveillance.
Henry T. Sampson Jr. / 1971-07-06
Sprint 6 advanced science record. The patent row preserves George H. Miley as co-inventor and does not convert the gamma-electric cell into a solar-cell claim.
Mark E. Dean / 1985-07-09
Sprint 6 networked computing record. The patent row preserves Dennis L. Moeller as co-inventor and IBM as assignee.
Lonnie G. Johnson / 1986-05-27
Sprint 5 commercialization candidate. Patent facts are not the same as licensing terms, toy-market performance, or ownership benefit.
Proof limits
The package uses patents as public records, not as private proof systems. That protects readers from both erasure and overclaiming.
Source review
The source-review route and staged next-profile page are noindex,follow and excluded from the sitemap. These cards show the claims and profiles that could improve the archive once sources are stronger.
