Whole-patent summary
Current Public-Information Position
Granted patent
18 issued claims.
Strong public correspondence
Multiple environment, user-control, performance, dynamic-condition, virtual-equipment and racing-surface features.
Partial public correspondence
Virtual participants, temporal race visualization and real-world motorsport context.
Core unresolved limitations
Physical race-event feed. Physical participant movement. Corresponding event-derived virtual participants. User competition against those participants.
Current legal position
No formal infringement conclusion.
Current commercial position
Sufficient technical and strategic relevance to justify further legal and commercial review.
Granted United States Patent
US 12,528,021 B2
System and Method for Facilitating Virtual Participation in a Racing Event
A granted U.S. patent position directed to the technical bridge between physical racing-event data and interactive virtual participation.

Patent Position Mapping
Final legal qualification
This presentation is based upon publicly available information and is intended solely to facilitate preliminary technical, intellectual-property and commercial review. References to technical correspondence do not constitute legal conclusions regarding infringement, validity, enforceability or claim construction. Those matters require consideration of the complete factual record, prosecution history, applicable prior art, confidential technical information where relevant and advice from appropriately qualified United States patent counsel.
Final presentation principle
The Controlling Reference Point
The granted patent remains the controlling reference point.
The iRacing technology ecosystem has been assessed against the patent — not the patent retrospectively fitted to iRacing.
The analysis identifies substantial technical correspondence, clearly preserves unresolved limitations, and provides a basis for informed legal and commercial review.
U.S. Patent No. 12,528,021 B2
Granted United States Patent Position
Patent Position Mapping — iRacing
A public-information technical and claim-level review identifying areas of correspondence, unresolved implementation questions and potential strategic IP relevance.
