As of today, I remain the sole inventor and owner of U.S. Patent No. 10,329,758, filed April 24, 2017.

No agreement has been executed in which I assigned, transferred, conveyed, or otherwise included my patent rights in any transaction involving VEEV, Lennar, or any affiliated entity.

To date:

• No member of Lennar leadership has requested assignment of my patent rights.
   
• No formal agreement has been executed between myself and Lennar or its counsel.
   
• No conveyance of ownership has occurred.
   

Any future alignment, license, acquisition, or resolution would necessarily be conducted directly and formally with the appropriate authorized representatives.

No indirect arrangement, intermediary discussion, or third-party representation constitutes a transfer of my rights.

I remain independent.

On April 24, 2017, I filed the patent application that later 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
   
• Spandrel-level (floor-line) drainage and moisture management
   
• Integrated enclosure performance logic
   

This filing represents the chronological foundation of the architectural system disclosed and claimed.

The matter at issue is not priority.

It is accurate boundary delineation and proper treatment of earlier-filed prior art.

On April 24, 2017, I met with senior representatives of The Related Companies and affiliated entities to present advancing enclosure-level concepts and related structural innovations.

In July 2017, New Hudson Facades filed patent applications directed to floor-line drainage and drying configurations.

Those filings addressed structural territory involving spandrel-level drainage assemblies — subject matter also addressed in my earlier-filed disclosures.

For clarity:

I have never conveyed, assigned, licensed, or transferred rights in my patented designs to New Hudson Facades, The Related Companies, or any affiliated entity.

No authorization has been granted to practice or commercialize my patented subject matter.

The New Hudson filings appear narrower in scope, focused primarily on spandrel-level configurations. Later VEEV filings operate in broader enclosure-level territory involving bonded assemblies and airflow logic.

Distinct systems may coexist provided boundaries are clearly delineated and respected.

When multiple later-filed initiatives operate in overlapping architectural territory, clarity of record and delineation of inventorship boundaries become essential to avoid market confusion.

On July 11, 2018, VEEV filed patent applications directed to prefabricated bonded wall assemblies incorporating airflow and conditioning elements.

These filings operate in enclosure-level architectural territory.

On September 8, 2023, I communicated directly with VEEV leadership regarding potential structural overlap. During that discussion, distinctions were asserted based on intended application in prefabricated housing.

From that date forward, actual notice of U.S. Patent No. 10,329,758 existed.

Following VEEV’s restructuring, certain VEEV-associated patent assets were transferred to Lennar-affiliated entities, as reflected in publicly recorded USPTO assignment documents.

Public USPTO records reflect that counsel for Lennar-affiliated entities, including Morrison & Foerster LLP, continue prosecution and review of certain applications.

On December 15, 2025, a Lennar-affiliated application that had previously been allowed was withdrawn from issuance and is currently undergoing further examination before the United States Patent and Trademark Office.

This reflects ongoing procedural activity. No further characterization is offered.

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.

Any representation suggesting inclusion of my patent rights within a broader asset transaction is incorrect.

PortalWall® and its associated architectural systems remain independently owned and available for licensing, partnership, and commercial deployment.

I am consulting with counsel to ensure that all public statements remain accurate and appropriately framed.

As additional verified information becomes available through formal legal and administrative processes, updates will be provided as necessary.

The objective is clarity, record integrity, and continued forward progress.

Yonatan Zvi Margalit
Inventor and Owner
U.S. Patent No. 10,329,758

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.
