204:1 Mr. Eraker, did you invent determining

204:2 camera geometry using plurality of images?

204:5 - 204:7 Eraker, David 08-03-2021 (00:00:07) Eraker_220515_1947.3

204:5 THE WITNESS: I don't believe so.

204:6 Q. (BY MR. MARTON) Okay. Did you invent point

204:7 clouds?

204:9 - 204:12 Eraker, David 08-03-2021 (00:00:13) Eraker_220515_1947.4

204:9 THE WITNESS: I don't believe so.

204:10 Q. (BY MR. MARTON) Did you -- did you invent the

204:11 use of geometric proxies and point clouds for generating

204:12 a 3D model?

204:14 - 204:14 Eraker, David 08-03-2021 (00:00:01) Eraker_220515_1947.5

207:19 THE WITNESS: Yeah, I'm not sure based upon

207:20 what I've seen.

208:1 - 208:3 Eraker, David 08-03-2021 (00:00:09) Eraker_220515_1947.8

208:1 Q. So, is it possible that the Google Art Project

208:2 model of The White House invalidates Claim 1 of the '673

208:3 patent?

208:8 - 208:8 Eraker, David 08-03-2021 (00:00:02) Eraker_220515_1947.9

208:8 THE WITNESS: Yeah, I'm not sure.

209:3 A. Yes.

209:4 Q. And it is a demonstration of a virtual model of

209:5 a -- of The White House?

209:9 - 209:16 Eraker, David 08-03-2021 (00:00:22) Eraker_220515_1947.11

209:9 THE WITNESS: I mean, we keep going over

209:10 this, Ryan. I mean, I don't know. I mean, I can't tell

209:11 just based on looking at these videos exactly what's

209:12 going on with this system or how it relates to our --

209:13 relates to the claims. I'm not a patent lawyer.

209:14 Q. (BY MR. MARTON) Okay. Well, it's a

209:15 demonstration of a digital representation of a 3D space,

209:16 correct?

209:18 - 210:4 Eraker, David 08-03-2021 (00:00:38) Eraker_220515_1947.12

209:18 THE WITNESS: Yeah, I'm not sure.

209:19 Q. (BY MR. MARTON) So The White House is a 3D

209:20 space, correct?

209:21 A. I'm not sure.

209:22 Q. You don't know if The White House is a 3D

209:23 space?

209:24 A. Yeah. I'm not sure.

209:25 Q. Okay. And do you know if the video shows a

210:1 digital representation of The White House?

210:2 A. I'm not sure.

210:3 Q. Okay. Do you know if image data was captured

210:4 to create this model of The White House?

210:7 - 211:8 Eraker, David 08-03-2021 (00:04:22) Eraker_220515_1947.13

210:7 THE WITNESS: Yeah, I'm not sure.

210:9 before this, there were people moving trollies around

210:10 The White House taking pictures, right?

210:11 A. I'm not sure.

210:12 Q. You don't -- you don't remember that? I'm

210:13 going to show you that video again. Oops. That's not

210:14 the video. My apologies.

210:15 (Video playing.)

210:16 Q. (BY MR. MARTON) So that video, which as you

210:17 can see from the screen is from April 4th, 2012, shows

210:18 cameras on trollies, correct?

210:19 A. I mean, Ryan, you keep asking me to speculate

210:20 on how this system works and I -- I just don't know.

210:21 Q. Well, I'm asking you, did you see cameras on

210:22 trollies in that video?

210:23 A. I mean, I saw a trolly. It's not clear what is

210:24 going on with the device.

210:25 Q. So you -- you can't tell if there's a camera on

211:1 that trolly?

211:2 A. I'm not sure.

211:3 Q. You can't tell if images of the different rooms

211:4 in The White House are being captured?

211:5 A. Yeah, I'm not sure.

211:6 Q. So you can't tell if each space in The White

211:7 House there are images captured to create a model of The

211:8 White House from that video?

211:11 - 211:19 Eraker, David 08-03-2021 (00:00:38) Eraker_220515_1947.14

211:11 THE WITNESS: Yeah, I'm not sure how the

211:12 Google system is working, Ryan.

211:13 Q. (BY MR. MARTON) That video just showed that

211:14 trollies moved around to the different rooms in The

211:15 White House to capture images, right?

211:16 A. I'm not sure.

211:17 Q. Okay. And do you know if image data that was

211:18 captured by those cameras was composited together to

211:19 create contiguous image of a scene?

211:22 - 212:1 Eraker, David 08-03-2021 (00:00:08) Eraker_220515_1947.15

211:22 THE WITNESS: Yeah, I don't know. I'm not

211:23 sure.

211:24 Q. (BY MR. MARTON) The person in the video said

211:25 that that's what was happening, right?
