1999 Mathematica Developers Conference
Patent Formulas Processed by Mathematica
Wolfram Research, in cooperation with the holder of the U.S. patent database contract, has developed a system for handling mathematical formulas in United States patents.
Thousands of patents have been processed using the Mathematica system and delivered to the U.S. Patent and Trademark Office.
The contractor for the patent database, Reed Technology and Information Services Inc. (RTIS), uses the Mathematica system to create both printed and electronic forms of mathematical formulas from the original materials submitted by inventors.
All mathematical formulas in all U.S. patents and in the official U.S. Patent Gazette are now typeset using Mathematica.
To meet the government's stringent typographic requirements and to ensure the most rapid and efficient formula entry, Wolfram Research worked closely with RTIS to develop the system.
"RTIS is excited about using Mathematica in high-volume production of mathematical items for U.S. patents. Our training time and processing time have been significantly decreased and our editors are thrilled with the clear interface customized by Wolfram Research," stated Paul Karleen, Operations Project Manager at RTIS.
Theodore W. Gray, Director of User Interfaces at Wolfram Research, noted, "The development and successful deployment of this system demonstrates that Mathematica is a powerful, practical platform for the creation of customized solutions to specialized computing problems. Any application requiring either sophisticated mathematical, typographic, or business logic implementation is a candidate for a Mathematica solution."
Making use of Mathematica's flexible and programmable user interface elements and high-level symbolic language, the system presents a streamlined, highly tuned interface to the production floor workers who enter formulas in over 3000 patents processed weekly by RTIS. The system is deployed on a large network of Windows NT workstations at the RTIS Horsham, Pennsylvania production facility.
The Mathematica system automatically creates multiple electronic files for each formula, including EPS, TIFF, notebook (NB file), and MathML. MathML is a new Internet standard representation of mathematical formulas developed largely by Wolfram Research and is now an official web standard. "This means that our solution lends itself well to web display and distribution," says Paul Karleen.
As part of the consulting process, Wolfram Research's technical staff contributed mathematical and scientific understanding to the typesetting process. The result is higher quality typography and a higher level of mathematical fidelity in the printed and electronic representations.
Wolfram Research provided tools and training to allow RTIS operators to correctly distinguish varying uses of commonly confused symbols such as e, i, j, and d, each of which is used in two fundamentally different ways in mathematical formulas.
MathGroup Marks Milestone
More than 20,000 messages have now been posted to MathGroup since its inception in 1988. MathGroup, a technical discussion newsgroup, is a free service of Steven M. Christensen and Associates, Inc.
Christensen, one of the first Mathematica users
and creator of MathTensor, started MathGroup shortly following the official introduction
of Mathematica. Members of the group post their questions to the mailing list and
usually receive rapid and expert help with their Mathematica questions. Many of the
world's leading experts on Mathematica, both inside and outside of Wolfram
Research, read and respond to user comments and problems.

Wolfram Research Applies for Cursor Tracker Patent
You don't have to be an experienced Mathematica user to appreciate the
functionality of the cursor-tracking capability of Mathematica 4. In this age
of high-resolution, multicolor computer display technology, temporarily losing track of
your cursor's position is a frequent occurrence. In particular, when navigating
mathematical expressions that are more two-dimensional than linear in nature, the cursor
can unexpectedly jump to a new position.
New Look for the Integrator
The heart of The
Integrator is Mathematica's built-in Integrate function, the same function used
when Mathematica is accessed directly. Visitors to the page can type in an integral and The Integrator's web server
sends a MathLink message to the Mathematica kernel, which then does the integral
using the built-in Integrate function. The result is sent via MathLink from the
kernel to the Mathematica front end, which produces typeset output. This output
then returns to the kernel, where it is sent back to the web server.
Virginia Tech Supports Mathematica Site License Renewal
Judging from the response of the Virginia Tech faculty and students who pressed for the
renewal of the site license, Mathematica has been well integrated into the courses
and laboratories at the institution. In August 1999, Virginia Polytechnic Institute
and State University (VA Tech) renewed its Unlimited Mathematica Academic Site
License for another three years.
