US 12,420,199 B2 · Granted 23 Sep 2025
Cross Game Play holds a granted U.S. patent on delivering a player's avatar and owned assets into multiple 3D platforms at runtime. We filed in May 2023. Since then, Netflix and Epic Games have publicly committed to the cross-game future this portfolio was built for, and AI is speeding it up.
FIG. 01 — The problem
Outfits, items and progress are bound to one title on one engine. When a game sunsets or a player moves on, what they paid for stays behind.
Every engine and platform wants its own mesh, rig and texture pipeline. Content gets re-authored over and over without adding any new gameplay.
Opening the gates is only valuable if each destination can still decide what comes in, in what form, and under whose rules.
Our vision
A persistent digital identity — your avatar, your items, your achievements — that travels with you across games, engines and worlds, while every destination stays in charge of its own gate.
FIG. 02 — The granted system
A content database holds the user's 3D avatar model and the assets they own.
An SDK sits inside each platform's own customisation module and requests the avatar through an API.
The content delivery module fetches the model and assets and delivers them to the SDK at runtime.
The player edits the avatar inside each game, using that engine's own tools.
New assets picked up in one game flow back to storage, so the identity keeps growing wherever the player goes.
Simplified from claim 1 of US 12,420,199 B2. Not claim language.
FIG. 03 — The trust stack
Moving a file is easy. Moving it in a way a destination will trust is the hard part. The granted patent is the foundation. The family of applications built on top of it covers each question a destination needs answered before it lets something in.
The destination decides. Verification isn't advisory.

Granted · Appl. 18/323,529 · Filed 25 May 2023
Claim 1, in part — “…a Software Development Kit (SDK) module adaptively integrated with the in-engine avatar customization module of each one of the multiple 3D rendering platforms…”
In preparation
A pipeline of 20+ further applications is in drafting. It covers the enforcement layer: rights, likeness, conformance and AI-assisted creation. Details are shared under NDA only.
*Estimated from the 25 May 2023 filing date plus 307 days of term adjustment, subject to maintenance fees and any disclaimers. Published status checked against Google Patents on 27 Oct 2026. Filed-but-unpublished status is from USPTO filing receipts and our portfolio records. See disclosures.
FIG. 05 — The market
Players spent more on games in 2025 than ever before, and a large share of it goes on in-game items. Today almost none of those items can leave the game they were bought in. Whoever makes them portable, on terms destinations accept, sits right in the path of that spending.
For what becomes US 12,420,199 B2: runtime delivery of avatars and assets into multiple 3D platforms.
18 claims issued, with continuation and CIP applications already filed.
To build avatars that let subscribers “carry their personas and fandom across different games.” Ready Player Me had raised $72M in venture funding. [2]
Fortnite cosmetics are named as the first proof point for using outfits across games, alongside a “shared economy for smart assets” and LLM access to the editor through MCP. [3][4]
Third parties are named only to show public market direction. Nothing here alleges infringement or implies any affiliation.
FIG. 06 — The thesis
AI has made writing code, generating art and shipping features cheap. Anything that can be built can now be rebuilt, faster and by anyone. What can't be rebuilt is a legal right.
With the best AI models, a competitor can rebuild software fast. They can't give themselves a May 2023 priority date.
AI can write the code. It can't backdate a filing.
What remains
The right to exclude.
A U.S. patent grants “the right to exclude others from making, using, offering for sale, or selling the invention throughout the United States.”
— Cover page, US 12,420,199 B2
Intangible assets now make up over 90% of the market value of the S&P 500. [5]
AI is pushing that trend further. When execution is abundant, value moves to whatever can't be copied. Every studio, engine and platform that builds cross-game portability with AI tools is building in the space this portfolio maps onto. That doesn't shrink the opportunity. It multiplies the number of conversations.
FIG. 07 — AI and the portfolio
AI makes assets cheaper to convert and create. A model can rebuild an outfit for a new engine or generate a whole world. The result is more assets moving between games, not fewer. Each one still has to be stored against a player's identity, delivered into each engine at runtime, and opened in that game's own customisation tools. That is the architecture claimed in our granted patent. AI doesn't replace that step; it sends more traffic through it. On top of that foundation, our filed applications cover the questions AI makes urgent: where an asset came from, who owns it, and whether a destination lets it in.
Illustrative · An AI-rebuilt asset arrives at a destination
A licensed outfit, owned by a player in one title.
A model regenerates it for a new engine. The file is new, so file-based protection sees nothing.
ACCEPT
Where AI changes the game, and the portfolio coverage that maps to it
Cheaper conversion means more assets moving between games. Each one still has to be delivered into each engine at runtime and saved back to the player's identity.
Copy protection fails once a model can recreate an item from a picture of it.
A generated world doesn't exist until runtime, so it can't pre-approve what players bring into it.
Companions and characters with memory need their identity and behaviour to survive a move between titles.
When an owned asset shows up in rendered or generated content, its owner needs to be counted and paid.
Engines are opening their editors to AI models. Epic is exposing Unreal Engine 6 to Claude, Gemini and custom models through MCP. [3]
Descriptions are simplified and are not claim language. Pending applications may not issue, and the scope of any issued claims may differ.
FIG. 08 — How the portfolio creates value
Engines, platforms and publishers building cross-game avatars and items license the rights to do it.
A conversion pipeline and SDK move avatars and items between engines. It's currently at prototype stage.
Transfer and marketplace economics on the assets that move, with creators keeping a share each time an item changes hands.
No commercial terms have been set. Nothing here is a projection.
