N.Y. Times, Saturday, June 25, 1988 I.B.M. Challenging Its Competitors' Use Of Key Technology The International Business Machines Corporation has begun warning its competitors that it thinks they are infringing on patents for the hottest new technology in computer design. By challenging its competitors, the world's largest computer maker is trying to assert the right to a technology that engineers think will dramatically improve tomorrow's computers -- ones that will be small and low-priced yet have much of the power of today's largest mainframe machines. If I.B.M. is successful, it could make it harder for other major computer and semiconductor makers to shift the balance of power in the industry in their direction, analysts said. The new technology, on which I.B.M. was a pioneer, is called RISC, short for reduced instruction set computer. Other manufacturers of RISC microprocessors and computers said they were surprised by the I.B.M. move, and several industry executives said they were not sure that the computer maker could fairly claim patent infringement. Among the dozens of competitors who are staking their futures on RISC are Sun Microsystems Inc., the Xerox Corporation, the Unisys Corporation and the American Telephone and Telegraph Company. I.B.M., which took the step after a wide-ranging review of its patents completed in April, said it hoped to increase revenue by licensing all of its technology, including RISC. "We are in the process of approaching companies where we think there may be an area of potential infringement or where we are suggesting that they wish to consider licensing some of our patents," said Jack D. Kuehler, I.B.M.'s vice chairman and the company's highest-ranking engineers [sic]. Immediately after the April review I.B.M. said it would permit competitors to license patents protecting its new PS/2 line of personal computers. But those competitors would also have to agree to the retroactive acquisition of licenses for other patents that protect the popular I.B.M. person computer line introduced in 1981. Previously, I.B.M. has had cross-licensing agreements with many large computer companies. As a result, the company has not aggressively policed the use of its patents by other companies. The April move is now seen by industry analysts as the first step in the new patent policy. Patents In Many Areas Mr. Kuehler declined to say in what areas the company might move next. However, I.B.M. holds patents in several areas, from computer data storage technology to sophisticated software organizers known as relational data bases. The company also has a patent in word processing. I.B.M. declined to state which companies it had approached about in infringing on the company's RISC technology. Officials at the Mips Computer Company, a Sunnyvale, Calif., maker of a RISC computer, said that they had not been contacted by I.B.M. They noted that the company had conducted extensive research into patents in the RISC field when it was founded in 1985. "It's not clear to me what they could claim that could affect the technology we've done," said John Hennessy, Mips's chief scientist and a faculty member at Stanford University. "It might be other companies' machines that have difficulties. I think we can trace every single thing we've done to work done at Stanford and Berkeley." He said that Mips had licensed technology that had been developed by an academic research project at Stanford. Executives at the Hewlett-Packard Company, Sun Microsystems, Motorola Inc., Fujitsu America, LSI Logic Inc., Advance [sic] Micro Devices Inc. and the Cypress Semiconductor Corporation -- all makers of RISC computers or microprocessors -- said that they had not been contacted by I.B.M. I.B.M. officials said that they were concerned about the possible perception that the company was attempting to steamroller the computer industry. But they stressed that events in the past year had led them to a commitment to re-evaluate the company's entire patent portfolio. "We have a much greater awareness of the need to protect our intellectual property and to recover appropriate value for it," Mr. Kuehler said. "We spend a lot of money and people's time developing our technology." The company has more than 9,000 United States patents and more than 23,000 related patents around the world. The RISC computer design concept involves radically streamlining the microprocessor, the heart of the personal computer and the driving force behind the modern computer industry. The new design approach eliminates many of the instructions for handling data built into the microprocessor and instead processes data by performing simpler steps repeatedly at faster speeds. Research into RISC was originally conducted during the mid-1970's by John Cocke, an I.B.M. computer scientist at the company's Thomas J. Watson laboratory in the Yorktown Heights, N.Y. Mr. Cocke's group developed a prototype machine called the 801 Minicomputer that was completed in 1980. In the early 1980's a number of academic researchers at institutions like the University of California at Berkeley and Stanford pursued independent RISC projects that led to commercial RISC chips. In fact, the Berkeley researchers coined the term RISC. More recently, virtually every major computer maker has introduced a RISC-based computer or announced plans to develop a system based on a RISC chip developed by a major semiconductor vendor. The rush to RISC foreshadows a major change in the computer industry. Modern chips are becoming so complex that the distinction between semiconductor makers and computer makers is beginning to disappear. "Over the next decade what you'll is an abrupt move out of the specialized computer room and onto the desk that will be based on the newest generation of RISC," said John East, a senior vice president at Advanced Micro Devices, a Sunnyvale, Calif., semiconductor maker. "RISC will be so close to the power of a mainframe that people won't want the extra cost and aggravation of a specialized computer room." I.B.M. executives dispute this view. They think that the rise of the RISC microprocessor will instead increase the growth rate of mainframe computers that will serve as the center of elaborate distributed computing centers. The increased power available on the desktop will be saked up in increasingly exotic ways like voice recognition and speech synthesis, Mr. Kuehler said. Impact of I.B.M. Move Analysts said that I.B.M.'s decision to pursue patent protection may have an impact on the leading RISC makers. "It will change the basis of the RISC business, and Sun must be quaking in its boots," said Stewart Alsop, publisher of P.C. Letter, an industry newsletter. "I doubt that I.B.M. had made a strategic decision to go after Sun, but the end result is that it ends up affecting Sun because they have been the only one who has been successful in commercially establishing RISC." Sun recently introduced an advanced RISC microprocessor and licensed it to a number of chip makers. The Sun design, called SPARC, has been adopted by major computer makers including Xerox, Unisys, and A.T.&T. I.B.M. said that the company now holds more than a dozen patents covering RISC design and has applied for more than a hundred more, Mr. Kuehler said. Mr. Kuehler said the company has continued to invest heavily in RISC research and has made progress toward developing a second-generation RISC technology. The company's first commercial RISC-based work station [sic], the I.B.M. PC RT, has been a commercial disappointment. However, the company is expected to introduce more powerful RISC work stations [sic] later this year.
