1. Herman is involved on the basis of application 09/488,960, filed 21 January 2000.
2. Barnes is involved on the basis of U.S. Patent 6,144,679, granted 7 November 2000,
based on application 09/232,169, filed 15 January 1999.
3. The real party in interest for Herman is Gregory S. Herman (Paper 3%).
4. The real parties in interest for Barnes are Science Applications International
Corporation (SAIC) and National Aeronautical and Space Administration (NASA) (Paper 23).
5. The subject matter pertains to a method and apparatus for producing a terahertz
electromagnetic wave by mixing two electromagnetic waves of specified wavelength using a
nonlinear crystal.
6. The involved Herman application contains claims 1-32.
7. The involved Barnes patent contains claims 1-32.
8. Herman claims 1-32 correspond directly to and are identical to Barnes claims 1-32.
9. The interference was declared with counts 1-32.
10. The counts 1-32 are Barnes' claims 1-32, respectively.
11, Count 1 is identical to Barnes patent claim 1 and is as follows:
A method for generating a terahertz band electromagnetic wave using a nonlinear crystal
having a Reststrahlen band of wavelengths including a fundamental Reststrablen
wavelength, the method comprising the steps of:
generating a first coherent electromagnetic wave of a first center wavelength shorter than
the fundamental Reststrahlen wavelength;
generating a second coherent electromagnetic wave of a second center wavelength shorter
than the fundamental Reststrahlen wavelength; and
mixing in the nonlinear crystal the first electromagnetic wave with the second
