`
`NAV-2001
`
`3 of 43
`
`

`

`application”) filed on August 28, 2008. Petitioner in the Inter Partes Review
`
`proceeding of the ‘840 patent relies on Boucher ‘552 for purposes of an argument
`
`under 35 U.S.C. § 103(a). In particular, the Petitioner alleges that Claims 1-2, 23,
`
`30, and 73 of the ‘840 patent are obvious under 35 U.S.C. § 103(a) over Jong, C.D.
`
`et al., Hyrdography, (1st ed. 2002) (“Hydrography”), an introductory-level textbook
`
`published in 2002 (See, RAY-1003), in view of Boucher ‘552.
`

`
`11.
`
`Prior to August 28, 2008, the effective filing date of Boucher ‘552,
`
`Mr. Maguire had reduced to practice, tested, and successfully operated the claimed
`
`invention of, at least, Claims 1, 2, 23, 30, and 73 of the ‘840 patent in the United
`
`States.
`
`12.
`
`In support of the foregoing statement of Paragraph 11, attached as
`
`Exhibit A is a partially redacted email from Mr. Maguire to me and other Navico
`
`engineers. (Only names and dates have been redacted.) At that time, Mr. Maguire,
`
`NAV-2001
`
`9 of 43
`
`

`

`these other engineers, and I were working in sonar technology and employed by
`
`Navico, Inc. I have reviewed the non-redacted version of Exhibit A, and declare
`
`that the email is dated and was sent prior to August 28, 2008.
`
`(a) Mr. Maguire states “Here are some images we have from a side-scan
`
`prototype gone wrong. The elements were potted facing almost strait [sic] down.”
`
`The “elements” Mr. Maguire tested were “side-scan” sonar elements, referring to
`
`long and narrow rectangular transducer elements. The transducer elements were
`
`maintained (“potted”) in their housing facing down, rather than to the side.
`
`(b) Mr. Maguire states “you do get great images of what is in the water
`
`column and a good idea of the bottom structure directly below the boat.” The
`
`“water column” refers to the water between the transducer element and the lake
`
`bottom. The “bottom structure” refers to, for example, submerged trees and rocks
`
`on the lake bottom.
`
`(c) Mr. Maguire includes two actual images produced by the transducer
`
`element connected to a sonar module during the testing. The images show trees
`
`and lake bottom structure directly below the boat as it traveled across the surface.
`
`(d) The sonar module included a sonar signal processor to process the sonar
`
`return signals and a transceiver to provide communication between the linear
`
`downscan transducer and the sonar signal processor. The sonar signal processor
`
`NAV-2001
`
`10 of 43
`
`

`

`included a display to create an image of the underwater environment as shown in
`
`the two images in Mr. Maguire’s e-mail.
`
`(e) Mr. Maguire states “I think this could be a nice complement to side-scan
`
`or may make a good standalone product.” The “complement to side-scan” refers to
`
`the ability of the downscan transducer elements to generate images below the boat
`
`in the gap between the port and starboard side-scan transducer images.
`
`13.
`
`In further support of the statement of Paragraph 11, attached as
`
`Exhibit B is a partially redacted first excerpt from a Lab notebook by Mr.
`
`Maguire. This first excerpt is entitled “Lake Testing” and details “Lab #10 down-
`
`scan.” I have reviewed the non-redacted version of Exhibit B, and declare that it is
`
`dated prior to August 28, 2008, and accurately reflects testing performed prior to
`
`August 28, 2008.
`
`(a) Mr. Maguire states “Tested Lab #10 as down-scan (pointed down),” and
`
`confirms the presence of me and three other Navico engineers. “Lab#10” refers to
`
`one of many Navico prototype sonar transducers for downscan imaging.
`
`(b) Mr. Maguire states “Lab #10 contains one xdcr.” The reference to
`
`“xdcr” is common short-hand for “transducer,” and the reference to “one xdcr”
`
`refers to a single rectangular, i.e., linear, transducer element.
`
`NAV-2001
`
`11 of 43
`
`

`

`(c) Mr. Maguire states “Images looked very good even at 800 KHz.,”
`
`Navico tested its rectangular downscan transducers at this frequency.
`
`(d) Mr. Maguire includes an image of the Lab #10 housing mounted to a
`
`boat. The housing was mounted to the stern of the boat, extending in a fore-to-aft
`
`position parallel to the surface of the water. This housing and mounting confirm
`
`the testing of Lab #10 “as down-scan (pointed down),” and illustrate positioning
`
`the rectangular transducer to project its fan-shaped beam down, perpendicular to
`
`the surface of the water.
`
`14.
`
`In further support of the statement of Paragraph 11, attached as
`
`Exhibit C is a partially redacted second excerpt from a Lab notebook by Mr.
`
`Maguire. This second excerpt is entitled “Lake Testing” and details “Lab #9, 10,
`
`11, 13.” I have reviewed the non-redacted version of Exhibit C, and declare that it
`
`is dated and accurately reflects testing performed prior to August 28, 2008.
`
`(a) The second excerpt refers to “Testing side and down scan at dive park,”
`
`and states “Down-scan did well at 800KHz, but could not image the bus or plane
`
`very well at 455KHz. The down scan lab#10 looked good in deep water (110 ft).”
`
`This refers to testing the rectangular downscan transducer element Lab #10
`
`attached to a boat on the water, and generating good images of a submerged bus
`
`and airplane at 800 kHz, but not at 455 kHz.
`
`NAV-2001
`
`12 of 43
`
`

`

`(b) The reference to generating images at 800 kHz and 455 kHz refers to
`
`operating the downscan transducer element at one of at least two frequencies.
`
`(c) Another excerpt states “Lab#13 used one side and one down,” and
`
`concludes “Should be OK to put down and sides in same housing and fire at same
`
`time.” This refers to placing multiple parallel rectangular transducer elements in
`
`the same housing with the “down” transducer pointed down below the watercraft
`
`and the “side” transducers pointed to the side of the watercraft (port and starboard).
`
`(d) Additional linear downscan transducer elements were tested (e.g., Lab
`
`#14, #15, #16, etc.) prior to August 28, 2008, including transducer elements
`
`approximately 120 mm long by 3 mm wide.
`
`15.
`
`In further support of the statement of Paragraph 11, attached as
`
`Exhibit D is a copy of pages from a partially redacted Lab notebook kept by Mr.
`
`Maguire. I recognize the handwriting as that of Mr. Maguire and recognize his
`
`signature on the page. One excerpt states “Lake testing on [date A] and [date B]
`
`indicated that there may be a use to making a down scan xdcr to give greater
`
`definition of the water column and ground below the boat.” I have reviewed the
`
`non-redacted version of Exhibit D, and declare that the section detailed on page 17,
`
`and date A and date B referred to in the above quotation, are dated and accurately
`
`reflect testing performed prior to August 28, 2008.
`
`NAV-2001

`

`

`(a) The notebook section includes the drawing below:
`
`1. The drawing shows a linear housing mounted to the stern of a
`
`watercraft with a single line therein denoting a rectangular transducer
`
`element.
`
`2. The drawing includes two handwritten notes with arrows pointed at
`
`the transducer. The notes state: “xdcr with rectangle element array”
`
`and “rectangular elements pointed strait [sic] down.”
`
`3. The drawing shows a down-facing fan-shaped beam emitted by the
`
`rectangular element and includes a note stating “rectangular element
`
`gives desired beam angle of ~1° x 50°.”
`
`4. The drawing shows the orientation of the transducer housing,
`
`transducer element therein, and fan-shaped beam with respect to the
`
`NAV-2001
`
`14 of 43
`
`

`

`watercraft, the surface of the water, and the direction of travel of the
`
`watercraft, as represented by the arrow pointing from the stern to the
`
`bow of the watercraft.
`
`(b) Mr. Maguire includes another drawing and states “result: gives great
`
`definition of bottom directly below the boat and excellent target definition of
`
`targets in the water column. Trees look like trees and rocks look like rocks.
`
`Basically side-scan with no shadows. Screen will look like this with trees.”
`
`The fan-shaped sonar beams are emitted as the boat travels. The sonar returns are
`
`received and processed for each fan-shaped region to create an image of the
`
`NAV-2001
`
`15 of 43
`
`

`

`underwater environment as a composite of images arranged in a progressive order
`
`(moving right to left) corresponding to the travel of the watercraft, as shown in the
`
`drawing of Exhibit D and images of Exhibit A.
`
`16. As further support for the statement of Paragraph 11, the following is a table
`
`that lists each claimed element of Claims 1, 2, 23, 30, and 73 and matches that
`
`element with at least one corresponding Exhibit that provides evidence of
`
`conception and reduction to practice of the claim element by Mr. Maguire prior to
`
`August 28, 2008.
