Seer Technologies awarded Distributed Computing Patent; Validation of the unique capabilities Seer brings to IS organizations and to the second generation of client server.

CARY, N.C.--(BUSINESS WIRE)--January 10, 1995--Seer Technologies Inc., a leading supplier of client/server application development solutions, today announced that it has been awarded U.S. Patent No. 5,295,222 for its distributed computing software facility.

The newly patented technology is an important part of the company's flagship Seer HPS product line. Seer HPS products provide an integrated tool set for designing, implementing and maintaining high-volume, multi-platform distributed applications.

The Seer Distributed Computing Patent is actually a patent for technology that supports the design, implementation and maintenance of partitioned client/server software. The patent grants Seer the right to prevent competitors from including the technology in their products made, used or sold in the United States. A corresponding patent has been granted in Australia, and related patent applications are pending in other countries.

"This patent award is an endorsement of the unique and significant capabilities that Seer's technology brings to IS organizations and to the second-generation client/server computing market," said Dennis McKinnie, vice president and general counsel, Seer Technologies. "Seer is completely committed to continuing its emphasis on research and development in the client/server arena, and is presently pursuing an active intellectual property protection program, including routine patenting of software inventions, because we are confident that our basic technologies can ably withstand the rigors of the patent approval process."

"I am pleased that our vision for distributed computing has been so widely accepted by our customers and validated by both the market and the U.S. Patent Office," said Vivek Wadhwa, executive vice president and chief technology officer at Seer.

Seer's patented technology enables the design and generation of applications that are partitioned and distributable across a heterogeneous computer network, including "three-tiered" environments. This capability provides users with great flexibility in implementing their applications across the enterprise. With Seer's technology, an application under development is modeled in several different ways in a centralized repository, and the models are used to generate computer code for the various hardware components of the network. New and upgraded application code is then automatically distributed to the hardware components.


Seer Technologies is a fast growing, privately held company founded to create and market tools and services for the design, development, deployment and management of multi-platform distributed applications. Its products and services are used by more than 5,000 developers around the world. The company was founded in 1990 and is based in Cary, N.C. Today, Seer Technologies employs more than 700 people in 27 offices throughout the U.S., Europe and Asia.

U.S. Patent No. 5,295,222 Wadhwa et. al.

U.S. Patent No. 5,295,222, which is assigned to Seer Technologies Inc., was issued on March 15, 1994, and will expire upon the conclusion of a 17-year period on March 15, 2011. The Seer 222 patent is a utility patent directed to an integrated software development facility for designing, implementing and maintaining computer programs for multiprocessor, heterogeneous, distributed operating environments.

The patent covers technology included in the Seer HPS family of products, and gives Seer the valuable right to prevent competitors from using the patented technology in their products.

Creating and distributing partitioned application software to run on networked multiprocessor systems, all with different types of operating systems, is a difficult process. The patented technology automates much of this process, including distribution of new or modified application code to the places where it is to run, and facilitates both re-use of parts of previously developed applications in new software development and modification of applications to handle new hardware or operating system configurations.

The patented technology is a method for creating computer source code and executable computer programs that are distributable across multiple hardware environments or platforms. The application development method can be broadly broken down into four phases: creation, repository storage, generation, and distribution.

In the creation phase, the application system being designed is defined by four models, each expressed in the form of an entity-relationship diagram.

The four models are:

o Data definition model, which describes the data to be used by

the program;

o Process definition model, which describes the procedures of

the program;

o A hardware configuration model, which describes the

connectivity data and operating environment requirements for

the network; and

o A logic model, which represents an application program in

terms of Seer's rules language.

In the repository storage phase, entity-relationship diagrams are stored in the same centralized database or repository.

In the generation phase, these four models are used to generate partitioned computer program modules, each of which is made up of computer code that is supported by the operating environment. Each computer program module is associated with its target hardware component.

In the distribution phase, the partitioned computer program modules are distributed through the network to the target hardware components.
