` Q. Good morning, Dr. Shahbakhti. 11:12:09
` A. Good morning. 11:12:11
` Q. So I introduced myself to you 11:12:12
`before we started, but I'll just introduce 11:12:14
`myself again. Again, I'm Jacob Zambrzycki, 11:12:16
`I'm with the law firm of Crowell & Moring, and 11:12:18
`we represent BMW against Paice and The Abell 11:12:20
`Foundation in several IPR proceedings. Today 11:12:26
`we're here with respect to one of those IPR 11:12:28

`Number 7,237,634, which I'll refer to as 11:12:33
`the '634 patent today. Is that all right? 11:12:38
` A. That is correct. And nice to meet 11:12:42
`you virtually. 11:12:43
` Q. Likewise. 11:12:46
` So you understand the deposition 11:12:49
`today has to do with the IPR concerning 11:12:50
`the '634 patent, correct? 11:12:51
` A. That is correct. 11:12:53
` Q. Great. I know you've been deposed 11:12:54
`a few times in connection with these IPRs with 11:12:58
`BMW, but I would like to go over some of the 11:13:01
`ground rules anyway just to refresh you on 11:13:03
`those. 11:13:07
` So first of all, as you know, I'm 11:13:07
`going to be asking you a number of questions 11:13:09
`today. You are to answer the questions to the 11:13:10
`best of your ability. 11:13:13
` Your counsel may make objections 11:13:15
`from time to time, but unless he instructs you 11:13:16
`not to answer, you are required to answer the 11:13:18
`question. 11:13:21
` Do you understand that? 11:13:22
` A. I do. 11:13:23

` Q. And it's important that you 11:13:24
`understand each question I ask you, so if for 11:13:27
`any reason you don't understand a question, 11:13:30
`whether you believe I'm misusing terminology 11:13:32
`or you think it's a stupid question, it makes 11:13:34
`no sense, please let me know if that's the 11:13:36
`case, if you don't understand the question 11:13:38
`that I ask. Is that okay? 11:13:40
` A. I will do. 11:13:41
` Q. Okay. And because we are taking 11:13:43
`this deposition remotely and via Zoom, you 11:13:46
`know, there may be some issues with the 11:13:51
`connection, and I may go in and out perhaps, 11:13:53
`or you may have some issues hearing me. If 11:13:56
`that happens, let us know as well, and that 11:13:58
`way just ask me to repeat the question and I 11:14:00
`would be happy to do that. 11:14:04
` A. Sure. Will do. 11:14:05
` Q. Okay. Let's try not to talk over 11:14:06
`each other. I'll try not to cut you off. I 11:14:10
`apologize if I do. I don't mean to. Also, if 11:14:12
`you can wait for me to finish my question and 11:14:15
`give your attorney an opportunity to object, 11:14:18
`just so we can avoid talking over each other 11:14:20

`for the court reporter's sake. 11:14:22
` A. Sure. Will do. 11:14:24
` Q. What else? Let's see. I'll try to 11:14:25
`take a break every hour or so. If you need a 11:14:38
`break before then for whatever reason, let me 11:14:41
`know. No problem. As long as there's no 11:14:43
`question pending, I'm happy to take a break. 11:14:45
`So just don't hesitate to let me know. 11:14:49
` A. Thanks. Will do. 11:14:52
` Q. And do you have any materials with 11:14:52
`you today at this deposition, Dr. Shahbakhti? 11:14:57
` A. The only thing I have, I have a 11:14:59
`folder on my desktop, and then this is the 11:15:05
`declaration that I have. That's how I 11:15:07
`received it from counsel. That's all I have. 11:15:10
` Q. Just your declaration? 11:15:12
` A. That's correct. 11:15:13
` Q. Okay. Got it. 11:15:14
` Are you aware of any reason why you 11:15:17
`wouldn't be able to testify to the best of 11:15:18
`your abilities today? 11:15:21
` A. No. 11:15:22
` Q. Are you on any medication that 11:15:23

`and accurately here today? 11:15:27
` A. No. 11:15:29
` Q. Is there any other reason why you 11:15:29
`are unable to give truthful and accurate 11:15:31
`testimony here today? 11:15:33
` A. No. 11:15:34
` Q. Okay. And finally, you understand 11:15:34
`that you're testifying under oath just the 11:15:38
`same as if you were to testify in court, is 11:15:40
`that right? 11:15:43

`use the chat function to send you a document 11:15:49
`that I would like you to take a look at. 11:15:53

` know how to use it. Okay. Let me know 11:16:00
` when you've received the document. 11:16:21

` A. I don't clearly remember. I might 11:17:29

` Q. How many hours would you estimate 11:20:26

`the -- all together. On this IPR. 11:20:41
` A. I would say it's kind of hard to 11:20:48
`separate these three IPRs, because they are 11:20:51
`all connected in terms of the content that 11:20:54
`they are offering, and in particular this IPR 11:20:59
`and the first IPR the claims are very much the 11:21:04
`same. So they are all relevant and connected. 11:21:06
` If I put the time that I have spent 11:21:09
`on preparing the declaration and also the 11:21:12
`depositions, it is easily over 200 hours. 11:21:15
` Q. And you're saying that's easily 11:21:21
`over 200 hours for all three IPRs? 11:21:23
` A. That is correct. I'm saying 11:21:26
`easily, so it might be even more than 250 11:21:37
`hours. 11:21:39
` Q. Sure. Okay. 11:21:40
` MR. ZAMBRZYCKI: I'm sending you 11:21:43
` now in the chat what has been previously 11:21:44

` could open that up and let me know once 11:21:50
` you've done so. 11:21:52

` Q. Okay. So exhibit 2017, that's your 11:22:08
`CV, is that correct? 11:22:10
` A. Yes, that's my CV dated 11:22:12
`February 9, 2021. 11:22:18
` Q. Okay. And was your CV accurate as 11:22:19
`of that date? 11:22:22
` A. Yes. 11:22:24
` Q. Are there any changes or updates to 11:22:25
`your CV, as you sit here today, since what was 11:22:28
`listed there on 2/9/2021? 11:22:31
` A. For professors the CV go up, so the 11:22:35
`number of pages will keep increasing as you 11:22:41
`have more publications, more activities that 11:22:44
`you do. So definitely there are updates. 11:22:46
` Q. Okay. So there has been additional 11:22:49
`publications since the time that you prepared 11:22:52
`this original CV? 11:22:55
` A. It should be. And I also involved 11:22:58
`in different activities. For example, I was 11:23:00
`on the review panel for the U.S. Department of 11:23:02
`Energy Vehicle Technology Program. So that 11:23:07

` A. Nothing to change. 11:25:05
` Q. Did you personally write this 11:25:06
`declaration? 11:25:08
` A. The process -- the process that I 11:25:09
`have gone through this, basically this 11:25:17
`declaration expressed my opinion, so every 11:25:20
`sentence and every word in this declaration 11:25:26
`represents my opinion, and the way we 11:25:29
`prepared -- I prepared this declaration was 11:25:34
`that I had meetings with counsel, expressed my 11:25:37
`opinions for the items related that I was 11:25:42
`asked to provide opinion for, and they 11:25:45
`prepared a draft, and then I edited and go 11:25:49
`through every sentence and every words, edited 11:25:54
`that, and then this comes to the declaration 11:25:59
`that we see today. And at the end, every 11:26:04
`sentence there, it's representing my opinion. 11:26:09
` Q. So Dr. Shahbakhti, I'm sending you 11:26:12

`document, Dr. Shahbakhti? 11:26:49
` A. Yes, I do recognize this document. 11:26:49

`time and varying the SP accordingly." 11:27:55
` Do you see that? 11:27:58
` A. Yes, I see that. 11:27:59
` Q. And you understand that that 11:27:59
`limitation is one of the limitations that's in 11:28:02

`please. 11:28:25
` A. Okay. I am at column 41. 11:28:36
` Q. Okay. And if you could take a look 11:28:37
`beginning at line 4 of column 41. It states, 11:28:40
`"It is also within the scope of the invention 11:28:44
`to make the setpoint SP to which the road load 11:28:47
`is compared to control the transition from 11:28:51
`mode 1 to mode 4 somewhat 'fuzzy,' so that SP 11:28:54

` Q. Would you agree that this is a 11:29:06
`disclosure in the '634 patent describing that 11:29:09
`claim limitation that we just looked at as it 11:29:15
`pertains to varying the SP accordingly? 11:29:18
` MR. RIFFE: Objection; calls for a 11:29:21
` legal conclusion. 11:29:23
` (The witness reviews document.)
` A. So first I'm going to read the 11:32:01
`claim, and then going to the -- the column you 11:32:02
`mentioned, and after that I'm going to refer 11:32:06
`to a part in my declaration. So -- 11:32:08
` Q. Dr. Shahbakhti, that's -- okay. So 11:32:13
`let's not do that. So -- 11:32:15
` MR. RIFFE: Counsel -- 11:32:17
` MR. ZAMBRZYCKI: I withdraw the 11:32:19
` question. I withdraw the question. 11:32:20
` Let's move on. 11:32:21
` Q. Dr. Shahbakhti, what were you just 11:32:22
`reading just now when I asked you the question 11:32:23
`and then you paused for several minutes before 11:32:25
`you responded to me? 11:32:27
` A. I look at the -- the paragraph that 11:32:28
`you asked me to look at it. I look at my 11:32:32

` Q. Okay. So I asked you about one 11:32:37
`sentence in column 41, lines 4 through 8, 11:32:39
`correct? 11:32:44
` A. That is correct. 11:32:45
` Q. Right. And you paused for several 11:32:46
`minutes and then you came back and you said 11:32:48
`you have to read the claim, read the patent 11:32:50
`and read the declaration again, is that right? 11:32:52
` A. I did not mean that. What I meant 11:32:56
`is that in order to properly answer your 11:32:58
`questions, that's how I'm going to formulate 11:33:01
`it and provide you a precise answer. So I was 11:33:05
`planning to provide you precise answer by 11:33:08
`first reading the words of the claim and then 11:33:10
`going to the words in the sentence you read, 11:33:12
`and then refer it to elsewhere a good example 11:33:15
`inside the declaration. Because my 11:33:20
`understanding is that we want to have a 11:33:21
`precision in your statement. 11:33:23
` So what I have, what I was trying 11:33:25
`to explain to you, it will clearly answer your 11:33:28
`question. 11:33:30
` Do you want me to do that, or do 11:33:30
`you want to skip the question? 11:33:32
