Patent-Pending Technology · U.S. App. No. 19/253,946

The patent-pending engine for real-time home equity.

EquityRail enables lending institutions to take a home equity line from application to funding in a single session — and to manage its risk continuously for the life of the line — as one patent-pending workflow. This site is an interactive working demonstration of the claimed workflow — U.S. Utility Patent Application No. 19/253,946 — designed to be licensed or integrated by the platforms and institutions that power home equity lending.

Borrower Side

Homeowners

One application, offers from funding institutions under their own brands, and equity designed to spend anywhere Visa, Mastercard, Apple Pay, or Google Pay is accepted.

EquityRail — The Claimed System

The Claims, Running

Don't read the patent. Drag it.

Three core claims of U.S. App. No. 19/253,946, implemented live on this page. What takes twenty pages of patent language takes ninety seconds with a slider — this is the mechanism your engineers would be licensing.

CLAIM 5 · ADAPTIVE LIMIT ALGORITHM

Limits that track collateral.

As valuation data streams in, every line's credit limit recalculates against the configured LTV ceiling — up and down, automatically.

$187,000
available credit limit
Live home value$540,000
Configured LTV ceiling
Existing liens$245,000
"New Credit Limit = (MedianValuationValue × ConfiguredLTV) − ExistingLiens, where ConfiguredLTV is set by the financial institution."
CLAIM 7 · AUTOMATED HALT & RESUME

Draws that police themselves.

Configurable soft pulls monitor the score. Below the halt threshold, draws stop; they resume only at the recovery threshold — hysteresis by design, no flapping.

DRAWS ACTIVE
bank-configured: halt < 550 · resume ≥ 620
Soft-pull FICO score700

Drag below 550 to trigger the halt — then notice draws stay halted until the score recovers to 620.

"…halts loan draws if the credit score falls below a bank-set threshold (e.g., FICO < 550) and resumes when the credit score meets a recovery threshold (e.g., FICO ≥ 620), based on configurable soft credit pulls."
CLAIM 6 · RATE = LOOKUP(SCORE, LTV)

Pricing from a bank-loaded table.

Each institution loads its own rate matrix. Tap any cell — the engine prices every line from the score tier and LTV, continuously refreshed by soft pulls.

7.24%
660–719 FICO at 80% LTV · variable APR
FICO ↓ LTV →70%80%90%
"…the smart contract applies an interest rate based on a lookup table: InterestRate = Lookup(CreditScore, LTV)."

Illustrative figures. The full claim set — 20 claims across platform, method, and system — also covers configurable monitoring intervals, DTI-based controls, and tokenized settlement.

What the Claimed System Unifies

How the claimed workflow differs from a conventional HELOC stack.

Existing lending systems automate individual steps of a static product. The claimed invention automates the entire lifecycle as one continuously managed process — after closing, for the life of the line.

The novelty is not automated HELOCs — pieces of this exist across the industry. The claimed invention is the unified system: real-time valuation-driven limits, continuous creditworthiness monitoring with automated draw control, and tokenized settlement operating as one interdependent process. That combination is what is pending before the USPTO — and what existing loan origination systems were never architected to do.

Interactive Patent Demonstration

Walk a loan through the claimed system.

This demonstration illustrates how the patented system would operate inside a financial institution — it does not represent a live banking platform. Three stops, about three minutes, on a phone.

Two Ways In

License it, or run it under your brand.

EquityRail is not seeking to become a retail lender. The objective is to license or sell the patent-pending technology to — or integrate it with — established financial institutions and software providers.

The Inventor

Built by someone who lived the problem.

Kelvyn C. Walker Sr. has spent more than 20 years in the real-estate and lending industry — including three years as a licensed mortgage broker and years of hands-on real-estate investing — watching home equity lending work the same way, at the same speed, decade after decade. A HELOC still takes weeks of appraisals and paperwork, and its terms freeze the day it closes, no matter what the collateral or the borrower does next. EquityRail is his answer: the invention claimed in U.S. App. No. 19/253,946, demonstrated end to end on this site. Based in Jacksonville, Florida.
