3. Numerical Technologies, Inc. Phase Shifting Circuit Manufacture Method and Apparatus Patent Number 6,258,493 July 2001 l Important to semiconductor manufacturing to create the features, lines and shapes on semiconductor wafers l Describes method through which limits on optical lithography can be overcome in order to shrink the size of integrated circuits, enabling more transistors to be placed on wafers of a given size l Cited by 42 later patents, age and technology would expect 4 citations. l March 2003 - Synopsys Inc. purchased Numerical for approximately $250 million…noting lithography technology as a major reason l Numerical built extensively on IEEE science, citing six separate IEEE papers. Levenson, M. et al., ‘Improving Resolution in Photolithography with a Phase-Shifting Mask,” IEEE Transaction on Electron Devices, vol. ED-29, No. 12, Dec. 1982, pp. 1828-1836. Paper is the foundation of phase-shifting technology. Source: The Influence of IEEE on Key Patents, Patrick Thomas, PhD, Anthony Breitzman, PhD; 1790 Analysitics, LLC, 12 January 2006

4. High Value Patent 6,233,550 University of California l ‘Method and apparatus for hybrid coding of speech at 4kbs,’ May 2001 l Speech coding and compression is an important component of communication systems. l Patent cites 37 previous publications. Out of these, 27 are articles in IEEE journals including articles ‘M-LCELP Speech Coding at 4 Kbps” and ‘High-Quality Speech Coding at 2.4 to 4.0 KBPS Based on Time-Frequency Interpolation”. l Scientific papers are an important pre-cursor to this patent on speech compression technology. l Patent cited by 26 subsequent patents; seven times the average number of citations received by patents in the same technology class and year Source: The Influence of IEEE on Key Patents, Patrick Thomas, PhD, Anthony Breitzman, PhD; 1790 Analysitics, LLC, 12 January 2006

5. Patents Exchange Monopoly Rights for Disclosure  Novel  Useful  Non-obvious  Turns invention into intellectual property  Protects the IP for up to 20 years  Encourages companies to divulge innovations for the public good

6. Hi-Tech Business Focus on Patents l Much of the high-tech economy relies on patents. l Most of the value of companies comes not from tangible assets (plants and equipment) but from intangible assets (patents, trademarks, copyrights) l Patents are the most tangible of intangible assets l Patent protection encourages innovation l All of the top patenting companies build upon science & technology

7. Patents with Scientific References l Contain new leading-edge ideas l Patents that only reference earlier patents are likely to be incremental improvements on earlier patented technologies
