Inventors
- Richard D. Haney (Employer not specified in the patent document at the time of filing, but he was the original assignor to X One Inc.)
Original assignee
X One Inc. was the original assignee. It is unclear from the patent text whether X One Inc. shipped a product embodying the claims. Their primary line of business, as inferred from the patent, appears to be related to developing and providing location-based services and applications for cellular wireless devices. Their current status is "Assignor" in the most recent assignment, suggesting they transferred ownership.
