PortalWall® Priority

Origin. Record. Continuity.

The Foundation

On April 24, 2017, I filed the patent application that issued as U.S. Patent No. 10,329,758.

That filing established the enclosure-level architectural baseline for:

• Bonded diaphragm panel assemblies
• Airflow-enabled drying and conditioning
• Decoupled spandrel-level drainage and moisture management (PortalWall® WDSA™)
• Integrated enclosure performance logic

This was not a component filing.

It was a system-level architectural framework.

PortalWall® begins there.

Ownership and Status

I remain the sole inventor and owner of U.S. Patent No. 10,329,758.

No assignment, transfer, conveyance, or license of ownership rights has occurred involving:

• VEEV
• Lennar
• New Hudson Facades / The Related Companies
• Hydronic Shell
• Or any affiliated entity

No indirect discussion or third-party representation constitutes a transfer of rights.

PortalWall® remains independently owned and controlled.

Subsequent Industry Activity

Following my April 2017 filing:

• July 2017 — New Hudson Facades filed applications addressing spandrel-level drainage configurations.
• July 11, 2018 — VEEV filed applications directed to prefabricated bonded wall assemblies incorporating airflow elements.

Public USPTO records reflect later assignment activity involving VEEV-associated assets and Lennar-affiliated entities.

Distinct systems may coexist in the marketplace.

What matters is boundary clarity and accurate recognition of earlier-filed architectural territory.

The matter is not priority.

The matter is proper delineation of enclosure-level invention.

Present Position

PortalWall® remains:

• Independently owned
• Available for licensing and partnership
• Commercially deployable

Ongoing procedural activity at the USPTO involving third-party filings does not alter ownership of U.S. Patent No. 10,329,758.

Clarity of record ensures clarity of market.

The BIG 3

When enclosure-level innovation advances, it attracts attention.

Over time, three distinct industry initiatives emerged in adjacent architectural territory:

1. Spandrel-level drainage refinements (without full system-level decoupling)
2. Prefabricated bonded wall assemblies
3. Vertical mechanical integration approaches

Each represents partial exploration of territory originally addressed at system level in April 2017.

Confusion arises when fragments are mistaken for foundations.

PortalWall® is the foundation.

The Objective

This page exists for one reason:

Record integrity.

PortalWall® was conceived, filed, and patented as an enclosure-level architectural system.

It remains so.

The work continues — confidently, clearly, and independently. 

Yonatan Zvi Margalit holds exclusive patent rights (US 10,329,758 B2) to an innovative window wall assembly system featuring our Within-Wall™ Cavity technology integrated within our PortalWall® Construct. This patented system encompasses a comprehensive architectural solution that creates a controlled cavity space between an insulated structural panel and an exterior architectural fascia panel, incorporating advanced moisture management, thermal performance, and structural integrity features. Our intellectual property protects the parts and the complete assembly, including the unique fastening systems, air and water management channels, U-shaped receptor and sill configurations, and the distinctive dry-side structural reinforcement with perpendicular airflow capabilities that define this next-generation building envelope system.
