`

`U.S. Patent No. 8,321,213
`IPR2022-00888
`
`I, Raymond O'Keefe Cruitt, state and declare as follows:
`
`1.
`
`I have prepared this Declaration in connection with Google LLC' s
`
`("Petitioner") Petition for inter partes review of U.S. Patent No. 8,321,213 ("the
`
`'213 patent"), which I understand will be filed concurrently with this Declaration. I
`
`have been asked to assume that May 25, 2007, is a date that is relevant for
`
`determining what is prior art to the '213 patent.
`
`2.
`
`I am currently Research Analyst at Finnegan, Henderson, Farabow,
`
`Garrett & Dunner LLP, 901 New York Avenue NW, Washington, DC 20001-
`
`4413.
`
`3.
`
`4.
`
`I am over 18 years of age and am competent to make this Declaration.
`
`I make this Declaration based on my own personal knowledge, based
`
`on my knowledge of library science practices.
`
`5.
`
`I earned a Master of Library Science ("MLS") degree from the
`
`University of North Carolina at Greensboro in 2004, and have worked as a
`
`librarian in various libraries, including law libraries, since then. I have been
`
`employed in the Research Information Center at Finnegan since 2019.

`
`The IEEE Xplore Database is a digital library used for accessing
`
`journal articles, conference proceedings, and other materials from the Institute of
`
`Electrical and Electronics Engineers (IEEE) and publishers. IEEE Xplore provides
`
`a date of publication for journals that IEEE Xplore represents is the "very first
`
`instance of public dissemination." See IEEE Xplore, Publication Dates, available
`
`at https://ieeexplore.ieee.org/Xplorehelp/working-with-documents/publication(cid:173)

`
`III. Public Availability
`
`A.
`
`Boll (Exhibit 1003)
`

`
`Evidence of Boll's publication and availability to the public includes
`
`the April 1979 date of the periodical "IEEE Transactions on Acoustics, Speech, &
`
`Signal Processing," which is identified on pages 113-120 ofExhibit 1003.
`
`Additional evidence is the copyright date of"© 1979 IEEE" on page 113 of

`

`

`U.S. Patent No. 8,321,213

`
`Exhibit 1003. In my opinion, this demonstrates that Boll was published in the IEEE
`
`Transactions on Acoustics, Speech, & Signal Processing periodical in April 1979.
`
`10.
`
`Further evidence of the publication and public accessibility of Boll is
`
`found in Appendix A, which is the IEEE Xplore database record of the IEEE
`
`Transactions on Acoustics, Speech, & Signal Processing periodical that includes
`
`Boll. Appendix A lists the "Date of Publication," which IEEE states is the "very
`
`first instance of public dissemination," as April 1979. Appendix A additionally
`
`identifies numerous citations to Boll, including 1629 IEEE citations, 1141 citations
`
`from "other publications" (2,770 total citations), and 305 patent citations. These
`
`citations include other publications and patents that cite to Boll, including many
`
`that pre-date May 25, 2007, the date I understand is relevant for determining what
`
`is prior art to the '213 patent. See Appendix A. For example, patent citation
`
`number 305 is U.S. Patent. No. 4,628,529 to Borth et al., which issued on
`
`December 9, 1985. Id at 33-34. In my opinion, this confirms Boll was published,
`
`cataloged, and publicly available to the public well before May 2007.

`Abstract:
`A stand-alone noise suppression algorithm is presented for reducing the
`spectral effects of acoustically added noise in speech. Effective performance of
`digital speech processors operating in practical environments may require
`suppression of noise from the digital wave-form. Spectral subtraction offers a
`computationally efficient, processor-independent approach to effective digital
`speech analysis. The method, requiring about the same computation as high-
`speed convolution, suppresses stationary noise from speech by subtracting the
`spectral noise bias calculated during nonspeech activity. Secondary procedures
`are then applied to attenuate the residual noise left after subtraction. Since the
