Patent holder profile

Mary B. Kenner and the home-access patent review

Kenner belongs in the health and home-accessibility queue, but CultureUp keeps the route noindex until the sanitary-belt primary patent trail is reconciled.

Why this belongs on CultureUp

Kenner is a public-record memory story.

This belongs on CultureUp because the patent record connects invention to place, public institutions, work systems, laboratories, employers, federal or corporate assignment, and the limits of public records.

Sprint 5 priority 4 / not final rankStatus: noindex_draftSource grade: B+

Patent: 4354643: Bathroom Tissue Holder
Issue date: 1982-10-19
Place: Washington, District of Columbia
Record strength: Patent-record facts are attached, but the strongest public claim remains under source review.
Identity evidence: Public context source attached where available; CultureUp does not use the patent row alone as race, ancestry, lineage, or Indigenous Black identity proof.
Sprint priority: 4 / not final rank
Cluster: Health, accessibility, and home safety
Needed before promotion: Attach the primary sanitary-belt patent record and source limits before indexable promotion.
Why this record matters: The route protects a high-value health and home-accessibility story from becoming stronger than the primary source trail.

Article profile

Read the person, place, invention, and record separately.

CultureUp keeps each layer visible so a patent record does not get stretched into claims the source trail cannot support.

The patent record

4354643 was issued on 1982-10-19 for Bathroom Tissue Holder.

The person in the record

The attached public context sources support a reader-facing profile frame. Any deeper life history, family record, school record, employment file, or community memory needs its own source trail.

Place attached to the claim

Washington, District of Columbia is the public place anchor used for this route. CultureUp does not infer local family continuity from the patent row alone.

The invention

The invention is summarized from the public patent title and source trail. Technical, market, institutional, and adoption claims stay limited to what the attached sources can support.

Business, labor, and use

Modern patent records often separate inventor, employer, assignee, licensee, and beneficiary. CultureUp keeps those categories apart instead of treating a patent as proof of ownership, wealth, adoption, or public impact.

What the record cannot prove

The patent record does not by itself prove full biography, race, ancestry, Indigenous Black identity, commercialization, institutional adoption, economic benefit, modern product lineage, or community memory.

Identity and correction note

CultureUp treats this as Black American patent memory only through public, reviewable sources. The page does not certify ancestry, descent, tribe, nationality, family history, or private identity.

Send stronger patent images, assignment records, employer records, licensing documents, public biographies, or source corrections through CultureUp's correction path.

Patent records do not prove final rank, private identity, solo credit when co-inventors appear, employment ownership, commercialization, adoption, or later public impact.

Noindex,follow until the source-review blocker is resolved.

Employer, assignee, and inventor status are not interchangeable. CultureUp names assignees when the patent record does.

Do not publish a strong sanitary-belt claim from this route until the primary patent record is ledgered.

CultureUp source review / source review pending

Supports: Keeps the sanitary-belt claim in review until a primary patent record is attached to the source ledger.
Limit: This review row does not prove the sanitary-belt patent claim. It prevents CultureUp from publishing a strong claim before primary patent evidence is ledgered.
