U.S. Patent 5,838,906, Filed in October, 1994, Issued November 17, 1998
Inventors: Michael D. Doyle, David C. Martin and Cheong Ang

First demonstrated publicly in 1993, this invention lifted the glass for the first time from the hypermedia browser, enabling Web browsers for the first time to act as platforms for fully-interactive embedded applications. The patent covers Web browsers that support such currently popular technologies as ActiveX components, Java applets, and Navigator plug-ins. Eolas' advanced browser technology makes possible rich interactive online experiences for nearly one billion Web users, worldwide.

MetaMAP: The First Open-Linking Hypermedia System
Method and apparatus for identifying features of an image on a video display
U.S. Patent 4,847,604, Filed in August, 1987, Issued July 11, 1989
Inventor: Michael D. Doyle

The MetaMAP system pioneered the use of clickable image maps in distributed hypermedia systems. It is also believed that the MetaMAP application was the first example of an "open-linking" hypermedia navigator, since it employed link references external to any single database. Previously, hypermedia systems were self-contained, representing all links between objects within a single monolithic database. A single small MetaMAP navigator application, on the other hand, could navigate through a potentially unending series of linked documents, no matter how large the collection of navigable documents might be. Later systems, such as the World Wide Web, similarly employed an open-linking architecture. The efficiencies that allowed the first MetaMAP application to provide instant object identification for tens of thousands of clickable objects in high resolution biomedical images, displayed on a 4.77MHz IBM PC, now enable the latest MetaMAP systems to deliver immensely-large multidimensional navigable image spaces for a variety of vertical applications. The patent also covers image space collision detection technology believed to be currently in widespread use throughout the computer game industry.

Transient Key Time Stamps
Method and system for transient key digital time stamps
U.S. Patent 6,381,696, Filed Sept of 1998, Issued April 30, 2002
Inventor: Michael D. Doyle

The Transient Key technology was inspired by the belief that real security can only be achieved by ensuring truth. If one can irrefutably and objectively prove that a piece of data existed at a point in time, and hasn't been changed since then, the truth represented by that data can be protected indefinitely. Now a part of the X.9.95 ANSI national standard for secure financial timestamps, this invention uses concepts such as transient secret cryptographic keys and distributed cross-certification chains to provide a system for irrefutably certifying the time and state of any digital data, without the need for a third-party certificate authority. This technology has become especially important in light of recent efforts by the U.S. Congress to tighten controls in the areas of information integrity assurance and data privacy protection. Dr. Doyle's Transient Key Time Stamp invention is a tool that can be used by any company that wishes to bring itself into full compliance with the Sarbanes-Oxley Act. Aetna, one of the world's largest health insurance companies, found that the Doyle transient-key invention was the only technology available that would allow them to satisfy the most difficult portions of the HIPAA regulations: "We have relationships with all the top software developers. We asked each of them if they could provide a scalable software solution that guarantees data integrity and proof of time. They said that nothing currently exists that would meet our needs.--- So far [Eolas-invented] ProofMark is the only viable solution we've seen that meets our needs." -- Mac Welch, CTO of Aetna, 2000.

Widely witnessed proof of time
System and method for widely witnessed proof of time
U.S. Patent 7,047,415, Filed April 26, 2001, Issued May 16, 2006
Inventors: Michael D. Doyle, Paul F. Doyle, Glenn Bernsohn, Jeff Roberts, Kirk Wolf, and Stephen Goetze,

A system for authenticating records without reliance upon a trusted third party. A first server provides a sequential series of certifications associated with discreet, non-overlapping time Intervals. The server can provide selected information to a second server which, in turn, incorporates the request and associated information in a cross-certification. The cross-certification is then provided to more other servers. Accordingly, a "chain-mail" of certifications among a variety of servers is provided. The system thus provides effective protection against a breach of security in any one server, resulting in increased reliability in the authentication of records.

Graphical indicia for the certification of records
System and method for graphical indicia for the certification of records
U.S. Patent 7,017,046, Filed April 26, 2001. Issued March 21, 2006
Inventors: Michael D. Doyle, Robert G. Hamilton, Marc V. Perrone, Paul F. Doyle, and Glenn Bernsohn

A system and method for authenticating records. Certification information may be encoded in graphical form. This graphical form, or design, may be referred to as an "Indicia." The record at issue may be printed out by a computer or stored electronically and bear on it an indicia that relates to the authenticity of the document. The indicia (and record) may then be scanned and interpreted by the computer to authenticate the record.

The ProofMark technology has been acquired by Proofspace, Inc., which no longer has any affiliation with Eolas.

zMap: Moving hotspots on video clips
Method and apparatus for identifying features of multidimensional image data in hypermedia systems

U.S. Patent 6,616,701, Filed on May 23, 1998, Issued September 9, 2003
Inventor: Michael D. Doyle

This invention turns full-motion video into a fully-interactive experience. Imagine, for example, being able to view a movie trailer and being able to click on individual actors, as they move across the screen, to bring up Web pages with more information on their bios, other films, etc. Or imagine that you're watching a video of the 1996 NBA finals, and being able to click directly on any of the players at any time to retrieve their stats, where they are now, etc. The zMap technology makes all that possible, and more.

Browser API Simulation
Method and system for hypermedia browser API simulation to enable use of browser plug-ins and applets as embedded widgets in script-language-based interactive programs

U.S. Patent 6,857,124, Filed on Jan 11, 1999, Issued February 15, 2005
Inventor: Michael D. Doyle

This invention provides the capability for high-level extensible scripting language interpreters to incorporate and employ Web browser plug-ins as components within script-based programs. A script interpreter extension is described which simulates the plug-in API interface of a Web browser, from the point of view of the browser plug-in, to allow program scripts to cause browser plug-ins to be launched and manipulated, in a manner similar to the scripting platform's native widgets, from within the executing program script. This system allows general program development systems to benefit from the large number of embeddable applications, in the form of browser plug-ins, that are available to easily expand the functionality of these development platforms at run-time, as well as to provide runtime binding of component logic with remotely-networked data objects.

The SAGA System
Method and system for multidimensional morphological reconstruction of genome expression activity
U.S. Patent application 20020048766, Filed in 2000
Inventors: Michael D. Doyle, Betsey S. Williams, Maurice Pescitelli, George Michaels

The SAGA system (Spatial Analysis of Genomic Activity) enables the automated large-scale discovery of the precise three-dimensional morphological distribution of the simultaneous gene expression activity of tens of thousands of genes in any biological tissue. The system combines the advantages of microarray chip technology with advanced 3-D visualization methods and advanced data analysis to provide a "snapshot" of the expression activity of all known genes within the spatial context of the biological structure.
