STEPHEN WICKER, Ph.D., DEFENDANTS' WITNESS, 6 PREVIOUSLY SWORN 7 DIRECT EXAMINATION (CONTINUED) 8 BY MR. APPLEBY: 9 Q. Welcome back, Dr. Wicker. 10 A. Good morning. 11 Q. I want to pick up where we left off yesterday 12 afternoon and maybe just take a brief step back so we 13 can reset where we were. 14 15 MR. APPLEBY: Could I have Slide -- yeah -- 10-31 brought up? 16 In fact, we were using a board. 17 Your Honor, may Dr. Wicker come back down 18 to the easel and the boards? 19 THE COURT: 20 MR. APPLEBY: 21 Q. Yes, he may. Thank you. (By Mr. Appleby) And, Dr. Wicker, can you 22 remind us what we were looking at here with this board 23 yesterday -- late yesterday afternoon? 24 25 A. Okay. This is a piece of the W-CDMA standard. It has to do with what are called channelization codes. Page 7 1 We talked a bit about channels last night. 2 The channels are basically individual pathways 3 through which data can be transmitted, and these codes 4 establish distinct channels. 5 specific codes that are used to create these channels. 6 The OVSF codes are the We talked a lot about this term. It's kind of 7 long, orthogonal variable spreading factor codes. 8 they form a tree, a very nice tree. 9 on its side. And This tree is lying But these are the various codes that form 10 the OVSF codes, which can be used to create channels in 11 W-CDMA. 12 Q. 13 14 And how many of those codes would be used to create a channel? A. Well, in theory, there's an arbitrarily large 15 number of codes. 16 reality, and in particular for the application we're 17 talking about here, there are 15 codes that can be used 18 to create channels, one code for each channel. 19 Q. It could just keep going. But in So that was -- I just want to emphasize that 20 one point. 21 many of those codes would I use? 22 A. So if I want to create a single channel, how Okay. Well, it's one code per channel. So, 23 for example, you could use this one code. 24 create one channel. 25 actually create four orthogonal channels by using those That would create one. That would We could Page 8 1 2 four codes. Q. Okay. Now, I think when we broke yesterday 3 afternoon, we were talking about whether these 4 orthogonal variable spreading factor codes were new with 5 W-CDMA and HSDPA. 6 7 Were they new in those standards? A. No. In fact, the underlying math is quite 8 old, but the codes themselves and their arrangement in 9 this tree goes back to the early '90s at least. 10 Q. Okay. 11 Let me show you -- 12 13 14 15 MR. APPLEBY: Let's bring up on the monitors Defendants' Exhibit 150. Q. (By Mr. Appleby) And, Dr. Wicker, if you could identify what we're looking at for us. A. Okay. This is an international patent 16 application -- international application. 17 been given to the inventor, Klein Gilhousen. 18 his name right there (indicating). 19 And it has There's Dr. Klein Gilhousen is one of the original 20 founders of Qualcomm. 21 name, Qualcomm, Incorporated. 22 23 24 25 Q. In fact, there's the applicant's And when was this international patent application filed? A. Let's see. There is an effective date here of 20th of July, 1993, right there (indicating). Page 17 1 A. Okay. This is the portion of the claim -- 2 and, again, it's Claim 5 of the '326 patent. 3 portion of the claim that adds the overlay to the 4 existing orthogonal channels. 5 code generator that's required. 6 over here so you can see it. 7 8 It's the So we have an overlay And so I've copied that There's a second encoder for encoding those overlay codes. 9 And that's right here. And then storage to store set of orthogonal 10 codes. 11 overlay -- sorry -- to store the various orthogonal 12 codes, which are called for up at the top. 13 14 Q. There has to be storage to store the various Now, did you find these highlighted elements in HSDPA-compatible base stations? 15 A. No. 16 Q. So I'd like to start walking through that 17 conclusion. 18 Before I get there, I'd like to ask whether the Court 19 has given us a construction for the term overlay code? 20 A. Yes, it has. 21 Q. And can you explain what that construction is? 22 A. That construction is over -- let me clear 23 that. 24 there (indicating). 25 That construction is over here. You can see it An overlay code is an additional code that Page 18 1 2 subdivides an orthogonal channel. Q. Now, in this version of Claim 5 that we now 3 have on the monitor, I see there's some highlighting in 4 blue and some highlighting in pink. 5 6 7 Could you tell us first what the highlighting in blue represents? A. The highlighting in blue represents the 8 original channels, the orthogonal channels that are to 9 be subdivided. 10 It includes a first encoder, an orthogonal code set, and orthogonal code generator. 11 So this is the part -- thinking back to the 12 very beginning when we were talking about the problem 13 that the patent solved, these are the original channels. 14 For example, the four orthogonal channels that 15 16 17 serve the neighborhood to begin with. Q. So these elements relate to that just classic CDMA; is that fair? 18 A. Yes, that's fair. 19 Q. Now, moving down the claim, we see elements 20 21 highlighted in pink. A. Okay. What does that represent? These elements represent the overlay 22 codes. 23 existing orthogonal codes so we can take care of the new 24 folks that have moved into the neighborhood who want 25 service, but we didn't have orthogonal channels for. This is the solution, what we put on top of the Page 22 1 multiply it by the first encoder. 2 channels, our original 4 channels, and so we have these 3 4 packets of data that have now been spread. 4 got 16 users. 5 encoder to apply the overlay codes and the result will 6 be 16 packets of data that we can now send at the same 7 time to our 16 users. 8 9 10 That creates our 4 But we've So what we're going to do is use a second And so they will all be getting the service. They will all be able to watch the movies and et cetera. Q. Okay. Now that we've taken a look at the 11 patent, I want to step back to the claim, Claim 5 of the 12 '326 patent; and ask you whether you found the pink 13 overlay code elements in HSDPA-compatible base stations? 14 A. The pink part? 15 Q. The pink part. 16 A. There were no overlay codes in HSDPA. 17 Q. Did you find an overlay code generator in 18 You asked about the pink? HSDPA-compatible base stations? 19 A. No. 20 Q. And did you find overlay codes? 21 A. No. 22 Q. And did you find a second encoder? 23 A. No. 24 Q. And could you explain your conclusions on 25 those points? No. Page 23 1 A. Yes. What I found was that it was a 2 straightforward CDMA system. 3 encoding orthogonal codes to create separate channels, 4 but there was no subdivision of those channels. 5 was no additional code that was used to subdivide any of 6 the existing channels. 7 occasion that couldn't change. 8 9 It had an encoder for There We simply had a fixed channel on I showed you the channels on the chart. were some data channels. This is the chart. There So there 10 are data channels and control channels. 11 change. Nothing here is subdivided by overlay codes. 12 Q. For the channels that we see on this chart, That doesn't 13 these are the channels that are used in HSDPA and 14 W-CDMA; is that correct? 15 A. That's correct. 16 Q. How many codes are used on each one of these 17 channels? 18 A. One. As I showed before, there is, for 19 example, one code of length 16 for channel 0. 20 to do. 21 Every one of these channels going down this list is one 22 code. 23 Q. It's hard One code of 116 for channel 1 and so forth. Now, we see on this chart that data channels 24 have a spreading factor of 16. 25 factor chosen? When was that spreading Page 24 1 A. That spreading factor was chosen when HSDPA 2 was first invented, when it was first put together by 3 the standards group. 4 5 6 Q. Does -- the spreading factor on the data channels for HSDPA, does that ever change? A. 7 No. No. It's fixed. If you used HSDPA from day one up until now, 8 it's going to be spreading factor 16 on the data 9 channels. 10 Q. Now, looking at these control channels, for 11 instance, the AICH, what is the spreading factor on that 12 channel? 13 14 15 16 17 18 A. The AICH is the one on the bottom, and the spreading factors, as you can see, is 256. Q. And when was that spreading factor for that channel, the AICH channel, chosen? A. Again, from the very beginning. It's been that way and it hasn't changed. 19 Q. 20 ever change? 21 A. No, not in HSDPA. 22 Q. Now, so after looking at these channels, does Can the spreading factor on the AICH channel 23 the -- do HSDPA-compatible base stations have an overlay 24 code generator? 25 A. No, they don't. Page 25 1 2 Q. And do they have a second encoder to apply an overlay code generator? 3 A. No. 4 Q. Now, you were in the courtroom when Dr. Wells, 5 Wi-LAN's expert, testified that HSDPA base stations met 6 this limitation, were you not? 7 A. Yes, I was. 8 Q. So let me show you a demonstrative that 9 10 Dr. Wells used. Do you recall Dr. Wells using this demonstrative in the course of his testimony? 11 A. Yes, I do. 12 Q. And do you recall Dr. Wells testifying that 13 this demonstrative, in his view, showed that HSDPA base 14 stations use overlay codes? 15 A. Yes. 16 Q. And do you agree with that conclusion? 17 A. No. 18 Q. And why not? 19 A. I think he's misreading the chart, because 20 what we see here is that -- in this particular example, 21 here we've got 14 high-speed physical downlink shared 22 channels that are using 14 different codes. 23 I believe he pointed to this code here 24 (indicating) and said that it had been subdivided to 25 create these channels. That's simply not right. These Page 26 1 channels down at the bottom, these control channels, 2 have a single sequence. 3 4 It's got spreading factor 256. This code of spreading factor 16 is never used. In fact, it can't be used. 5 If you've got this particular set of length 6 256 sequences, this code is blocked. 7 at all. 8 subdividing this particular sequence; you can't use that 9 sequence. You can't use it 10 It's not a matter of taking overlay codes and We're instead using different sequences down 11 here of length 256 to create our reliable control 12 channels. 13 14 15 Q. There's still only one code for each channel. Have you seen other documents that confirm your opinion on this point? A. Yes. 16 17 MR. APPLEBY: Exhibit 28. And can you pull up the whole -- yes. 18 19 20 21 Let's put up Plaintiff's Thank you. Q. (By Mr. Appleby) And what are we looking at here, Dr. Wicker? A. Okay. This is a document from something -- I 22 think I've got a copy here. 23 It's a document from Qualcomm University. 24 creates these documents to teach their incoming 25 engineers and others how the technology works. Well, maybe not. Qualcomm Page 27 1 And this particular one is for HSDPA. It 2 says: Understand -- actually, it says: 3 HSPA. There might have been some confusion earlier. 4 5 HSPA is high-speed packet access. actually two directions. 6 7 It's It's uplink and downlink. HSDPA, high-speed downlink packet access is part of HSPA. 8 9 Understand Q. Okay. And when did you first see the document? 10 A. I'm pretty sure it was at least a year ago. 11 Q. This was a document that Wi-LAN was relying on 12 in its case, was it not? 13 A. Yes. 14 Q. So let's move back to the slides, and I'm 15 Yes, I did see it here in court. going to show you a diagram that's in this -- 16 17 MR. APPLEBY: Can you go to the next slide? 18 Q. (By Mr. Appleby) And what we are looking at 19 here, this is a diagram that appears in the document we 20 just looked at. 21 A. Okay. This is another -- yet another OVSF 22 tree. 23 code is associated with each channel. It's got the sequences, and it's showing how one 24 25 In this case, once again, we have our data channels. There's 15 of those, so we pick out 15 codes, Page 28 1 as it says there, for our 15 channels. 2 3 Now, we've also got control channels, and the control channels are down here (indicating). 4 Now, these control channels are using 5 sequences of length 128 and 256, as I showed you on that 6 chart earlier. 7 not subdividing this channel. 8 channel is actually blocked. 9 What that says, though, is that we're Quite the opposite. That There's some language right here that explains 10 what that X means. 11 thank you -- blocked by lower code in tree. 12 It says: Blocked by lower code -- So what that means is, not only is this 13 channel not being subdivided; it can't be used at all. 14 It's blocked by the use of these sequences down here, 15 the sequences of length 128 and 216. 16 Q. Now, looking at those control channels that 17 you were just pointing out, those were established in 18 the standard in 2002; is that right? 19 A. That's correct. 20 Q. So given that those control channels are 21 established in the standard, can this code that's 22 circled in red as spreading factor 16 ever be used in 23 HSDPA? 24 25 A. No. No, it can't. It's been blocked by the use of these sequences down here for the control Page 29 1 channels. 2 in tree. 3 Q. It specifically says: Blocked by lower code If I use this code here, I can't use this one. Can an orthogonal channel spread with that 4 code circled in red, ever be created in HSDPA at any 5 time? 6 7 8 9 10 A. No. If you did, you would interfere with your control channels. Q. Now, do you recall Dr. Wells testifying that a 256 chip OVSF code includes an orthogonal code and an overlay code? 11 A. Yes. 12 Q. Do you agree with that conclusion? 13 A. No. 14 Q. And why not? 15 A. I think it goes against the Court's claim 16 construction, first. 17 said the overlay codes are additional codes. 18 portions of a code or expansions of a code; it's an 19 additional code. 20 Q. The Court's claim construction Not And just so we're clear on what Dr. Wells is 21 calling the overlay code and the orthogonal code, in his 22 view, the first 16 bits of the 256 chip code were the 23 orthogonal code? 24 understood? 25 A. Is that -- was that what you That's correct. Page 30 1 2 3 4 5 6 Q. And what did you understand the overlay code to be? A. The overlay code was the actual code itself; in other words, the length 256 code. Q. So the overlay code was the entire 256 chips in Dr. Wells' view. Is that what you understood? 7 A. That was my understanding. 8 Q. He wasn't saying that it was the first 16 bits 9 10 11 for the orthogonal code and the remaining 40 were the overlay code. A. That's not what he testified to, was it? That's correct. He was actually using the 12 first 16 bits twice. 13 both the orthogonal code and part of the overlay code. 14 15 16 Q. He said the first 16 bits were And do you think it's proper to use the first 16 bits twice to satisfy the overlay code construction? A. No. I think the Court was clear that it's an 17 additional sequence. 18 twice. 19 Q. You can't count the same sequence Now, do you recall Dr. Wells testifying that, 20 in his opinion, an OVSF code was equivalent to an 21 orthogonal code and an overlay code? 22 A. Yes. 23 Q. And do you agree with that testimony? 24 A. No. 25 Q. Why not? Page 31 1 A. Well, what the patents call for is this 2 ability to use overlay codes to subdivide existing 3 orthogonal channels, so you can serve more users, take 4 care of more subscribers. 5 The simple use of one code doesn't do that. 6 It doesn't give you that ability to expand the system to 7 cover more people. 8 9 10 And furthermore, using two codes and using one code, that's substantially different. 13 14 One code uses one encoder; two codes have two encoders that are required. 11 12 You've just got one code. So they seem like very different things to me. Q. Do you find the differences to be substantial or insubstantial? A. I would say they're substantial, because 15 basically you've got one system that's fixed, it can 16 serve a certain number of users, and that's it -- 17 namely, the HSDPA; it's got 15 data channels; it's 18 fixed -- whereas, the other system, the one that's 19 described in the patent is flexible; you can subdivide 20 channels by using additional overlay codes to serve more 21 subscribers. 22 Q. I think that's a substantial difference. Now, do you recall Dr. Wells testifying that a 23 256 chip code could be viewed as a 16 chip code 24 multiplied by another 16 chip code. 25 Do you recall that? Page 32 1 A. Yes. 2 Q. And do you agree with Dr. Wells that that 3 means that it's equivalent to an overlay code and an 4 orthogonal code? 5 A. No. 6 Q. Why not? 7 A. Well, first off, he's simply underlying some 8 underlying mathematics that have been well-known for a 9 long time. 10 Secondly, he could have done 16-by-16 or he 11 could have done 4-by-4-by-4-by-4, and then we've got 12 four codes. 13 place if we're going to count them like that. 14 can't be right. 15 Q. You know, we can have codes all over the That That can't be what the claims mean. And is that type of multiplication, a 16-bit 16 code times another 16-bit code, does that ever happen in 17 HSDPA? 18 A. No. 19 Q. Now, were OVSF codes known before Airspan 20 filed for its patents? 21 A. Yes. 22 Q. And did we see that earlier? 23 A. Yes. 24 Q. Can you explain that? 25 A. Basically, OVSF codes, the underlying Page 34 1 of the overlay code patents? 2 A. No. 3 Q. Now, I'd like to direct your attention to 4 another aspect of Claim 5, and I have advanced the 5 slide. 6 7 Could you tell us what we're looking at here? A. Okay. This is the portion of the claims that 8 covers selective operability. 9 this a little bit yesterday afternoon. 10 I think we talked about But basically what it says is: A second 11 encoder, selectively operable instead of the TDM 12 encoder. 13 So you've got this ability to go back and 14 forth. 15 first solution that uses overlay codes and then the 16 second solution that uses time division multiplexing. 17 What this language tells me is that you can Remember, there's two solutions. 18 choose either one. 19 but both are available. 20 21 Q. There's the You can't do both at the same time, You can pick one or the other. And do the patents illustrate how this might operate? 22 A. Yes. 23 Q. So I have put up the Figure 7B of the patents, 24 25 and could you describe what we're looking at here? A. Okay. There's a lot of stuff going on here, Page 47 1 have to have buffers. 2 The buffers are what hold the data while you operate on 3 it. 4 inventors knew that. An engineer would expect that. The people who wrote the patent knew that; the 5 So when they contrasted on-the-fly with 6 storing the entire set, they knew there were going to be 7 buffers, but they're saying there's a difference between 8 generating them on-the-fly, like the base stations do, 9 and storing all of them so you just read them out of 10 memory. 11 So I think what the claims are calling for is 12 storing all of the orthogonal codes so when you need 13 one, you simply read it out of memory. 14 to generate it again; you read it out of memory. 15 simply latching in one code is not the same as storing 16 all the codes so you don't have to generate them. 17 18 19 Q. You don't have And And the claim language is storage arranged to store the set of orthogonal codes; is that right? A. That's right. And, of course, the language, 20 the set of codes, means all the codes, the codes that we 21 talked about earlier in the claim. 22 Q. Okay. Sir, I'd like to summarize your 23 opinions on Claim 5 with respect to Alcatel-Lucent's 24 base stations. 25 And could you summarize them for us? Page 48 1 A. Okay. What we see here, once again, are the 2 last two claim elements. 3 elements call for a number of things that are simply not 4 present. 5 And the last two claim The accused products do not have an overlay 6 code generator. 7 apply overlay codes. 8 store the set of orthogonal codes. 9 set of codes. 10 They do not have a second encoder to And they do not have storage to They don't store the They generate them on-the-fly when they need them. 11 Since those three claim requirements are not 12 present, these last two elements here cannot be 13 satisfied. 14 the claim is not infringed. 15 16 Q. And if all the elements aren't satisfied, So now I'd like to turn to the other two asserted claims in the '326 patent, Claim 2 and Claim 9. 17 Have you reached a conclusion about whether 18 Claim 2 would be infringed by HSDPA-compatible base 19 stations? 20 A. Yes, I have. 21 Q. And what is that conclusion? 22 A. Claim 2 is not infringed either. 23 Q. And why not? 24 A. Well, we look at Claim 2, and we can see some 25 of the same language. We need an overlay code Page 51 1 a dependent claim. 2 Claim 7 as well as the additional stuff in Claim 11. 3 Q. It includes everything that's in And so what conclusion have you reached as to 4 whether Claim 11 is infringed by HSDPA-compatible base 5 stations? 6 A. It's not infringed. 7 Q. And why is that? 8 A. Well, if we look at Claim 7 -- and remember 9 Claim 7 is included in Claim 11 -- we have a number of 10 familiar requirements. 11 generator, the second encoder, and there's the storage 12 requirement. 13 Okay. There's an overlay code It looks like we've repeated the 14 same -- overlay code generator, storage arrange, 15 store -- I think that's actually in the original claim. 16 Anyway, so what we've got are a series of 17 elements that I've already shown you are not present. 18 There is no overlay code generator. 19 encoder to apply overlay codes. 20 to store the set of orthogonal codes. There's no second And there's no storage 21 Claim 7 requires that, but it's not present. 22 Claim 11 requires everything in Claim 7, so Claim 11's 23 not infringed either. 24 25 Q. And would your conclusion be the same for Alcatel-Lucent's base stations in particular? Page 55 1 A. Yes. 2 Q. Do you agree that that's what this patent 3 describes? 4 A. No. 5 Q. And why not? 6 A. Well, you can see that from the language of 7 the patent. 8 code division multiplexed channel out of commission. 9 What the patent's calling for is taking a You're not taking something out of commission 10 if I simply take it from one user and give it to 11 another. 12 13 We're locking them out from all users, not simply reassigning them. 14 Q. 15 patent. 16 17 18 That's not what that means. So let's turn to the asserted claims of this I want to look at Claim 11 to start with. And can you tell us what we have highlighted here? A. Okay. Claim 11 is on the left, and what I've 19 done is I've highlighted portions of two of the claim 20 elements, the analyzer portion, which I've blown up 21 here, and the channel controller portion, which I've 22 blown up here (indicating). 23 The analyzer is what determines how much 24 interference from other cells is there. 25 analyzer for receiving parameters -- I'll skip some of So it says an Page 66 1 Q. Now, we've been talking about interference, 2 this being an example of interference from within the 3 cell, but are there other factors beyond interference 4 that could affect the value of a CQI? 5 A. Yes. 6 Q. And so let's talk about what some of those 7 things might be. 8 9 10 11 And could you explain what we're looking at here on this Slide 67? A. Okay. affect CQI. This is a variety of things that can Some of them have already been discussed. 12 But, remember, CQI is an indication by the 13 phone of what it thinks it can receive successfully. 14 So if there are obstructions, interference 15 from inside and outside the cell, that's going to affect 16 what the phone can receive. 17 But one thing to note, the quality of the 18 phone is actually an issue. 19 tables for different kinds of phones. 20 There are different CQI If we have a really nice phone, it's what we 21 call high sensitivity, it's able to pick signals up out 22 of the noise and do so very well. 23 So its CQI, in a given situation, is going to 24 be higher than a less expensive phone, may not be as 25 well designed, not as sensitive. It's not as good at Page 67 1 picking signals out of the noise. 2 So we may have two phones that are seeing 3 exactly the same conditions, but they'll have different 4 CQIs because one is better at pulling signals out of a 5 noise than the other. 6 7 A couple of other things I have listed: control plays a factor. 8 9 Power Distance. The further you are from the antenna, the less the signal quality. 10 Weather. 11 In fact, it's a serious problem for satellites 12 as well. 13 communications. 14 Heavy rain affects signal quality. communications. 15 16 Q. But heavy rain does affect cellular Lightning definitely affects cellular Now, if I had a smartphone in my hand and I walked into a building, could that affect my CQI? 17 A. Yes. 18 Q. And is that interference from other cells? 19 A. No. 20 Q. And if I walked into an elevator with my 21 phone, could that affect my CQI? 22 A. It will definitely affect your CQI. 23 Q. And is that interference from other cells? 24 A. No. 25 Q. If I'm in a rainstorm, could that affect my Page 68 1 CQI? 2 A. Yes, it will. 3 Q. Is that interference from other cells? 4 A. No. 5 Q. If I'm moving in my car, could that affect my 7 A. Yes. 8 Q. Is that interference from other cells? 9 A. No. 10 Q. Now, can a base station ever tell why a mobile 6 11 12 CQI? unit, a smartphone, reports a change in its CQI? A. No. A variation in the CQI could be caused by 13 many factors. 14 base station, and the base station won't know where the 15 CQI changed. 16 Q. 17 Those factors are not reported to the Is CQI a parameter indicative of interference from other cells? 18 A. No. 19 Q. And why do you say that? 20 A. There are many situations in which the 21 interference from other cells may actually improve, but 22 the CQI gets worse. 23 So you cannot look at the CQI, and in 24 particular, you can't look at changes in CQI and make 25 any determination about what's happening with Page 69 1 interference from other cells. 2 Q. Okay. 3 4 5 You simply don't know. MR. APPLEBY: So let's turn back to Claim 11. Q. (By Mr. Appleby) And have you formed an 6 opinion, Dr. Wicker, as to whether HSDPA-compatible base 7 stations have the analyzer required by Claim 11? 8 A. Yes. 9 Q. And what is that opinion? 10 A. It's not present. 11 Q. And why do you say that? 12 A. There is nothing in the handsets that's able 13 to tell how much interference is being -- is coming from 14 adjacent cells. 15 Q. There's simply no way to do it. And, therefore, the base station has no 16 information regarding whether a handset is experiencing 17 interference from other cells? 18 A. 19 That's right. The base station will simply know roughly what 20 the handset thinks it can receive. 21 into that particular number. 22 Q. 23 24 25 Many factors come So let's move to the last element of Claim 11. And could you remind us again what the last element requires. A. Okay. That's the channel controller. This is Page 70 1 the portion of the claim that takes that estimate of how 2 channels are being affected by other cell interference 3 and takes some of those cells out of the people, takes 4 them out of commission, and says: 5 be used by anybody in the cell, because of this 6 interference from other cells. 7 8 Q. These channels cannot And do HSDPA-compatible base stations satisfy that element of Claim 11? 9 A. No. 10 Q. And why do you say that? 11 A. We talked a lot about HSDPA and the 15 data 12 channels. 13 within the cell if there's data to send. 14 situation in which one of those channels is locked out, 15 taken out of use because of interference from other 16 cells. 17 Q. They're going to be allocated to someone There is no It simply doesn't happen. Looking back at this demonstrative that we 18 used earlier in the day, is there anything on this 19 figure that -- that relates to that opinion? 20 21 22 A. Yes. What this shows, once again, our 15 codes, they create 15 data channels. Okay. Going this way, as we go from TTI to 23 TTI, transmission time interval to transmission time 24 interval, all those channels are being used. 25 being assigned to different users at different times; They're Page 81 1 2 All right. I'd like to walk through those. So let's talk about the overlay code generator. 3 What you actually, sir, are saying is that the 4 overlay code generator is not there because it is not 5 separate from the orthogonal code generator. 6 two code generators, don't you, sir? You want 7 A. No. 8 Q. I'm sorry? 9 A. No. 10 Q. Well, that's -- that's the position you've 11 taken in this case, is that you need the overlay code 12 generator to be separate from the orthogonal code 13 generator. They can't both operate together. 14 A. I don't agree. 15 Q. Well, sir, what you're trying to do is simply 16 insert into the claim, additional language that doesn't 17 appear in the claim. 18 claim that it is separate from the orthogonal code 19 generator; that they have to be separate generators. 20 You're trying to insert into the And the reason for that is because HSDPA uses 21 one code generator, doesn't it? 22 codes from the same generator, doesn't it, sir? It generates one set of 23 A. That's correct. 24 Q. Well, let's look at overlay code. 25 Again, your construction of overlay code is that it has to be Page 82 1 separate from the orthogonal code. 2 shoehorn that language into the claim, even though it 3 doesn't appear. 4 5 So you'd like to So the overlay code has to be separate from the orthogonal code. That's your approach? 6 A. I do agree that it has to be separate. 7 Q. Okay. Let's look at the second encoder. Yes. You 8 want the second encoder to be separate from the first 9 encoder. 10 Again, you need to see two different encoders 11 because HSDPA uses one encoder, and the Alcatel-Lucent 12 base stations products use one encoder. 13 you want to shove into the claim language that it is a 14 separate -- that the second encoder is separate from the 15 first encoder, don't you, sir? 16 A. I don't agree. 17 Q. So then -- all right. And so, again, 18 the next -- to the next point. 19 All right. Let me -- let me go to Let's look at your -- the 20 orthogonal code generator is a storage arranged to store 21 the set of orthogonal codes. 22 23 And this is DDX 10-53. Do you remember talking about that with Mr. Appleby? 24 A. Yes, I do. 25 Q. And actually, during your testimony, you said Page 84 1 2 Q. All right. to the three -- 3 4 5 Let's talk about -- let's go back MR. WEAVER: Can you pull up Claim -- sorry. Q. (By Mr. Weaver) Let's talk about the '327 6 patent for a minute, and I want to walk you through what 7 you discussed with Mr. Appleby. 8 9 10 Now, you argue that the Alcatel-Lucent products don't infringe the '327 patent because the CQI doesn't measure essentially only intercell interference. 11 Isn't that what you're arguing? 12 A. Yes. 13 Q. And it doesn't just need to be indicative of. 14 So we can strike that language. 15 measuring whether the wireless link is subject to 16 interference solely from signals generated by other 17 cells. 18 19 It needs to be only That's really your opinion, isn't it, sir? A. It is my opinion that the analyzer has to 20 receive parameters indicative of, and I'm simply 21 interpreting that word indicative. 22 23 24 25 Q. So you interpreted the word "indicative of" to mean only measuring the interference from other cells? A. That's right. from other cells. It indicates the interference Page 85 1 Q. And you went through testimony where you said 2 there's interference that's caused by other things, 3 correct? 4 A. That's correct. 5 Q. There's intercell interference. 6 in an elevator. 7 It might be You said those things could happen. But, sir, if you hold all of those things 8 constant and the interference from another cell changes, 9 you'd agree that the CQI that's measured would change, 10 don't you? 11 12 A. If everything was kept constant, including the type of phone, the sensitivity of the phone -- 13 Q. Correct. 14 A. -- the only thing that changed was other cell 15 interference, then you're correct. 16 change only because of the other cell interference 17 change. 18 Q. 19 All right. Yes, the CQI would So let's look at what happens as a result of that. 20 Now, you've said that the claim requires that 21 you selectively reduce the number of code division 22 multiplexed channels in the channel pool from the entire 23 cell. 24 25 So no one in the cell can use those channels; that's your opinion? Page 88 1 2 codes? A. That's correct. 3 MR. WEAVER: 4 Can you pull that up? 5 Q. Can I have DDX 61, please? (By Mr. Weaver) Now, I want to go back to the 6 '327 for a second, because you were pointing out that -- 7 that in the specification that you remove channels from 8 the whole pool -- or from the whole cell, rather, when 9 you have interference. 10 Do you recall that? 11 A. Yes, that's correct. 12 Q. So DDX 61 is the slide you used during your 13 presentation. 14 A. Yes, it is. 15 Q. And "preferably" is the word that's on that 16 chart, isn't it? 17 specification, isn't it, sir? That's language from the 18 A. Yes, that's correct. 19 Q. So that's an embodiment. 20 embodiments disclosed in the patent. 21 It's one of the with me? You would agree 22 A. Yes. 23 Q. And trying to limit the claims to the 24 embodiment shown in the patent would be improper, 25 wouldn't it? Page 89 1 A. That would -- that's correct, yes. 2 Q. Okay. 3 4 MR. WEAVER: Q. Let's go back to the slides. (By Mr. Weaver) Now, you also said that 5 Alcatel-Lucent's base stations do not have what is 6 called -- any kind of storage; is that correct? 7 A. No, I didn't say that. 8 Q. I apologize. 9 10 any kind of storage. You didn't say it didn't have You said they didn't have storage as required by the -- Claim 5. 11 A. That's correct. 12 Q. Okay. 13 Well, let's look at that software again, if we can. 14 You see down here (indicating) -- 15 16 MR. WEAVER: up, Jennifer, please, right here in the middle. 17 18 19 And if you could blow this Oh, it's a PowerPoint. Q. All right. (By Mr. Weaver) So if you focus on this section (indicating) -- do you see that? 20 A. Yes. 21 Q. And you see where I've highlighted ROM? 22 A. Yes, I do. 23 Q. And that's read-only memory, isn't it? 24 A. That's correct. 25 Q. Okay. So it is, in fact, using ROM, isn't it, Page 100 1 A. That's correct. 2 Q. Claim 5 also requires a first encoder, right? 3 A. That's correct. 4 Q. And that's the first encoder to apply the 5 orthogonal codes from the orthogonal code generator, 6 right? 7 A. Yes. 8 Q. And there is another element in the claim that 9 10 requires a second encoder to apply overlay codes; is that right? 11 A. That's correct. 12 Q. Now, if we look at the Court's construction of 13 overlay code, the Court construed overlay code as an 14 additional code that subdivides an orthogonal channel, 15 right? 16 A. That's correct. 17 Q. Did you apply that construction? 18 A. Yes. 19 Q. And you were asked a lot of questions about 20 whether you were using the word "separate." 21 recall that? 22 A. Yes. 23 Q. Is that the construction you applied, or did Do you 24 you apply the construction that an overlay code must be 25 an additional code that subdivides an orthogonal Page 101 1 channel? 2 3 4 A. The construction that I used was an additional code. Q. 5 So let's talk about what Dr. Wells is doing. Dr. Wells says that the 256-chip spreading 6 factor code that's used on control channels is both an 7 orthogonal code and an overlay code. 8 Is that your understanding? 9 A. That's correct. 10 Q. So when he does that, what is he calling the 11 orthogonal code in that 256 OVSF chip -- OVSF code that 12 is used to create the control channel? 13 14 15 16 17 18 19 A. He's referring to the first 16 bits of the 256-bit OVSF code as the orthogonal code. Q. And what is he calling the overlay code in that 256-chip OVSF code? A. He's referring to the entire 256-chip sequence as the overlay code. Q. So he's not saying that the first 16 chips are 20 the orthogonal code and the additional 240 chips are the 21 overlay code. He's not saying that, is he? 22 A. That's not my understanding. 23 Q. And he's actually taking the first 16 chips of 24 that code and counting them twice to get both an 25 orthogonal code and an overlay code; is that correct? Page 102 1 A. That's correct. 2 Q. Do you think that meets the Court's 3 construction? 4 A. No. 5 Q. Why not? 6 A. It's not an additional code. 7 8 9 10 He's using the same code bits twice. Q. Now, you were also asked about other opinions you might have about some of the other elements, and you certainly are an expert in this case, right? 11 A. Yes. 12 Q. And you provided opinions on the claims for 13 all three claims of the patents we discussed today, 14 right? 15 A. That's right. 16 Q. And you provided opinions on elements other 17 than the ones we discussed this morning? 18 A. That's correct. 19 Q. Now, you understand that we've had a limited 20 amount of time here. I think we have 15 hours a side. 21 A. Yes, that's my understanding. 22 Q. So we've focused on a subset of your arguments 23 so that we could streamline the presentation. 24 25 Is that your understanding? A. Yes. Page 117 1 the high -- that can't be used for high-speed downlink 2 data, because it's frankly too small of a pipe, isn't 3 it, at that point? 4 5 6 A. I think it would be more accurate to say it's simply too slow. Q. The data rate is too slow. Too slow. 7 Let me go back to the overlay code. 8 Now, you agree with me that the basis of your 9 opinions is that the overlay code must be separate from 10 11 12 13 the orthogonal code. A. My use of the construction was for additional. I understood additional to mean a separate sequence. Q. So you agree with me, your opinions are based 14 upon your view of the Court's construction that an 15 additional code must be a separate code. 16 A. That's correct. 17 Q. And so if the Ladies and Gentlemen of the Jury 18 don't agree with you, then your opinions are not 19 appropriate in this case. 20 A. If they feel that I'm not using the 21 construction properly, then they can -- they can take 22 the consequences -- excuse me -- conclude from that that 23 I'm not doing it properly. 24 25 Q. All right. Thank you. MR. WEAVER: Your Honor, Plaintiffs move Page 118 1 Defendants' Exhibit 173. 2 THE COURT: 3 MR. APPLEBY: 4 THE COURT: 5 MR. WEAVER: 6 THE COURT: 7 Be admitted. Thank you, Your Honor. All right. MR. APPLEBY: 9 11 No objection. Any further redirect? 8 10 Any objection? Just briefly. REDIRECT EXAMINATION BY MR. APPLEBY: Q. You were asked some more questions about the 12 overlay code. 13 code that subdivides an orthogonal channel? Has Dr. Wells pointed to an additional 14 A. No. 15 Q. And why is that? 16 A. There isn't one. 17 Q. There's only a single OVSF code used on each 18 19 20 21 22 channel in HSDPA; isn't that right? A. That's correct. One channel/one code. There are no additional codes. Q. Now, just a couple of questions on CQI. You were asked a question about if we hold all 23 other things constant and we have interference from 24 other cells, then that CQI will be indicative of other 25 cell interference. Page 124 1 You understand the question? 2 THE WITNESS: 3 THE COURT: 4 Yes, Your Honor. Any objection from Defendants? 5 MR. APPLEBY: 6 THE COURT: 7 No objection. Any objections from Plaintiffs? 8 MR. WEAVER: 9 THE COURT: No, Your Honor. All right. I continue to be 10 amazed at our East Texas juries' comprehension of the 11 technology. 12 You may bring the jury in. 13 (Pause in proceedings.) 14 (Jury in.) 15 THE COURT: 16 All right, Dr. Wicker. 17 Please be seated. The jury has some questions for you. 18 The first question: Is there 19 documentation in patent '327 that states that the first 20 and second code generator can actually be one code 21 generator? 22 THE WITNESS: 23 given in terms of two separate generators. 24 25 THE COURT: No. All the examples are Based on that, does the HSDPA standard specify being separate generators or both Page 143 1 Q. Now, when you mentioned that -- as part of 2 your investigation, you reviewed the HSDPA standards, 3 correct? 4 A. That's correct. 5 Q. Did you see any reference to overlay codes in 6 the HSDPA standard? 7 A. No, I did not. 8 Q. Well, did you also -- you understand the Court 9 has construed the various terms in the patents, right? 10 A. That is correct. 11 Q. What is the Court's construction for overlay 12 13 14 15 code? A. It is an additional code that subdivides an orthogonal channel. Q. Did you use that claim construction in 16 analyzing whether the Ericsson base stations or Sony 17 Mobile products infringe these patents? 18 A. Yes, I did. 19 Q. So you mentioned product documentation. Did 20 you look at any textbooks or other resources to assist 21 in your investigation? 22 23 24 25 A. Yes. I looked at textbooks, articles, along with the standards. Q. Now, I want to step back to another slide that the jury has seen a couple of times already. Can you Page 145 1 2 Q. And when you talk about a length of 256, what are you referring to? 3 A. 4 in the code. 5 add up to 256. You're referring to the number of bits that's If you count the number of bits, you would 6 Q. And now are bits the same as codes? 7 A. No, they are not. 8 Q. How are -- how many -- how many possible 9 values are there for a bit? 10 A. There's only two. 11 Q. There's only two? 12 A. For a bit, yes. 13 Q. Okay. 14 What are those possible values under the HSDPA standard? 15 A. They would be 1 or negative 1. 16 Q. Is there any limitation on the number of codes 17 18 that are possible? A. No, there are not. They could be up to 19 uncountably long codes, based on that recursion function 20 we saw earlier. 21 22 23 24 25 Q. Now, how does the HSDPA standard define the codes that are used? A. It defines them in these standards documentation. Q. And when it says that the OVSF codes are Page 146 1 2 3 channelization codes, what does that mean? A. That means that you use these OVSF codes -- a single OVSF code to create a single channel. 4 Q. Just a single code? 5 A. Yes. 6 Q. What do the -- what do the patents require? 7 A. The patents require an orthogonal code and an 8 overlay code that's an additional code that subdivides 9 an orthogonal channel. 10 Q. And what are you showing in this slide? 11 is -- I think is a figure that we just saw when 12 This Dr. Wicker was up here. 13 14 A. Again, we're showing the OVSF code tree here from a Qualcomm document. 15 Q. When was the first time you saw this document? 16 A. The first time I saw it was when I was looking 17 at the preliminary infringement contentions from the 18 Airspan patents. 19 Q. And when you say the preliminary infringement 20 contentions, you're referring to a document that Wi-LAN 21 served as part of this lawsuit? 22 A. That is correct. 23 Q. Okay. And is it your understanding that those 24 infringement contentions where Wi-LAN first sets forth 25 its allegations of infringement? Page 147 1 A. Yes, it is. 2 Q. You've highlighted some things in this -- on 3 this figure. 4 highlight? 5 A. What -- what did you high -- what did you Well, once again, this figure shows that when 6 you assign a code to a particular channel, you block 7 other assignments. 8 9 10 11 So the X shows what's being blocked in the OVSF code tree. Q. And I think there was some discussion about this position right here (indicating). 12 Do you see that? 13 A. Yes. 14 Q. Is that a channel? 15 A. No. 16 Q. What is that? 17 A. That's a code word in the code tree. 18 Q. Can there be a channel created at that 19 particular location under the HSDPA standard? 20 A. No. 21 Q. And why is that significant in light of 22 whether the overlay patent -- how is that significant 23 with respect to what the overlay code patents require? 24 25 A. As we've heard from the Court's claim construction, the overlay code is an additional code to Page 148 1 subdivide a channel. 2 Wi-LAN has been pointing to these control 3 channels here in the bottom right; but as you can see, 4 as soon as you assign a control channel lower in the 5 tree, everything else above it is blocked. 6 use that for assignment. 7 Q. You cannot And so when you say you can't use it for 8 assignment, are you saying there's not a channel that 9 can be subdivided? 10 11 12 13 A. There's not a channel that can be subdivided in an OVSF tree. Q. And is that something that the Court's claim construction requires? 14 A. Yes, it is. 15 Q. And how is that? 16 A. Because we have a Markman order stating that 17 the overlay code is an additional code to subdivide an 18 orthogonal channel. 19 Q. 20 Let's take a look at the claim language. Based on your investigation, did you reach 21 some conclusions with respect to the Ericsson base 22 stations? 23 A. Yes, I did. 24 Q. And what did you determine? 25 A. That the Ericsson base stations accused do not Page 149 1 infringe the overlay code patents. 2 Q. And why is that? 3 A. Because, first of all, there's no overlay 4 code. 5 Q. Anything else? 6 A. There's also -- because there's no overlay 7 code, there's no overlay code generator. 8 Q. Anything else? 9 A. And since there's no overlay code, you don't 10 11 12 have a second encoder for applying the overlay code. Q. Now, you heard Dr. Wicker talking about a couple of other elements of Claim 5 of the '326 patent. 13 A. Yes, I did. 14 Q. And specifically, he was pointing to the 15 selectively operable language. 16 A. Yes, he was. 17 Q. Do you agree with Dr. Wicker's opinion 18 regarding the selectively operable language? 19 A. Yes, I do. 20 Q. How about the opinions that Dr. Wicker gave 21 with respect to the storage element? 22 A. I agree with those also. 23 Q. Now, are there other claims asserted against 24 25 Ericsson base stations from the '326 patent? A. Yes, there are. They are Claim 2 and Claim 9. Page 151 1 2 Ericsson base stations can infringe that claim? A. Again, because there's no overlay code; 3 there's no overlay code generator; there's no second 4 encoder, the Ericsson base stations do not infringe 5 Claim 11 of the '819 patent. 6 7 Q. Let's take a look at the '327 patent, which you referred to as the other cell interference patent. 8 What claims are asserted against Ericsson? 9 A. Against Ericsson, it's Claims 11 and 12. 10 Q. And are those claims the same as what 11 Dr. Wicker addressed earlier? 12 A. Yes, they are. 13 Q. If we take a look at the limitations of the 14 15 claims, what do they require? A. They require a number of things. I have 16 chosen to highlight just a portion of the claim right 17 here, which is the section talking about the analyzers 18 for receiving parameters pertaining to a wireless link 19 within the cell, indicative of whether that wireless 20 link is subject to interference from signals generated 21 by another cell. 22 And also here in the channel controller, the 23 limitation regarding selectively reduce the number of 24 code division multiplexed channels in the channel pool 25 in order to reduce the effective interference from other Page 152 1 2 cells. Q. And do you understand the allegations that 3 Wi-LAN is making with respect to Claim 11 of the '327 4 patent? 5 A. Yes, I do. 6 Q. And this is a slide that's similar to what 7 8 9 we've seen before. A. They are accusing the CQI. What factors can influence CQI? It can be influenced by any number of factors because -- 10 Q. Can you give us some examples? 11 A. As you've already heard: Obstructions, 12 interference within the cell, which is called intracell 13 interference; or interference from another cell, which 14 is called intercell interference; quality of the phone. 15 Actually, the quality of the phone's receiver 16 is most important; how the control algorithm is working 17 in a TDMA system; and also function and absolute 18 distance you are from the cell phone. 19 20 Q. And did you review any materials to determine how the CQI is -- is generated? 21 A. Yes, I did. 22 Q. Okay. 23 A. I looked at textbooks and Ericsson 24 25 And what did you look at? documentation. Q. When you say textbooks, can you give an Page 153 1 example of one of the textbooks you've looked at? 2 A. Sure. This textbook here called 3G Evolution 3 was written by four Ericsson engineers, and it discusses 4 CQI. 5 Q. 6 7 I think that book has been designated DX 283. How did you -- did you rely on that book in doing your investigation? 8 A. Yes. 9 Q. Okay. 10 And what does the 3G Evolution book say about the calculation of the channel quality indicator? 11 A. It says that the CQI -- generally, the CQI 12 represents the instantaneous channel conditions. 13 what the cell phone is receiving at this particular 14 time. It's 15 Q. Does it explicitly state the channel quality? 16 A. Well, it goes on to say the CQI is not an 17 explicit indication of channel quality. 18 before, it's actually a request from the cell phone to 19 the cell phone tower saying give me this much data; I 20 believe I can handle this much data accurately. 21 22 23 But as we heard So it just continually requests data over and over again. Q. Does the CQI provide any information to the 24 base station as to why the CQI has the particular value 25 it does? Page 154 1 2 3 4 A. No, it does not. It's just a number from 0 to Q. Does it indicate whether a particular wireless 30. link is experiencing intercell interference? 5 A. No, it does not. 6 Q. Does it indicate whether a particular wireless 7 link is subject to an obstruction? 8 A. No, it does not. 9 Q. Does it indicate whether a particular wireless 10 link is subject to interference from within the cell? 11 A. No, it does not. 12 Q. Does it indicate anything about the reasons 13 why it has the particular value it has? 14 A. No, it does not. 15 Q. Now, can the CQI be affected by the design 16 17 18 19 20 21 or -- of the mobile phone itself? A. Yes. As I stated earlier, how advanced your receivers are, can affect your CQI value. Q. Did you look at any Ericsson documentation that actually explains that? A. 22 Sure. So this is the HSDPA User Plane document from 23 Ericsson. 24 about the calculation of channel quality estimate. 25 And here in Section 8.1, they're talking The important thing to see here is that the Page 155 1 CQI, first of all, is a recommended amount of data that 2 you want to send down, such that the UE thinks he's 3 going to receive the data with only a 10-percent 4 probability of loss. 5 The base station, which is what we're talking 6 about here, perceives the UE, which is the mobile, as a 7 black box. 8 means we're not going to go look in and figure out 9 what's going on there. 10 And it's kind of an engineering term that A black box is something you don't -- kind of 11 imagine it as a teenager's bedroom. 12 know what's going on in there. 13 get the request out for the data, and you're going to 14 operate on that. 15 You don't want to All you want to do is And they go on to state that even a good 16 receiver can report higher CQI than a bad receiver, even 17 if you're in the same channel conditions. 18 Q. So that would mean if two phones were 19 experiencing the exact same amount of intercell 20 interference, they could report different CQIs? 21 A. Yes, they could. 22 Q. And so in that way, does the CQI indicate 23 whether either of those phones is experiencing 24 interference from other cells? 25 A. No, it does not. Page 156 1 2 3 Q. Now, what conclusions did you reach regarding the '327 patent? A. Okay. For at least that reason, there is no 4 receiving parameters indicative of whether the wireless 5 link is subject to interference from other cells. 6 There's also no selectively reducing the 7 number of code division channels in the pool in order to 8 reduce the effect of interference from other cells. 9 Q. Did you hear questioning about whether the 10 channel pool related to all of the channels that were 11 available for the establishment of wireless links? 12 A. Yes, I did. 13 Q. And what is your opinion with regard to that? 14 A. My opinion is that channel pool applies to the 15 central terminal. 16 central terminal and not for a particular user. The channel pool is for the entire 17 Q. 18 patent? 19 A. Yes, it is. 20 Q. And with respect to the '211 patent that's And is that how it's described in the '327 21 asserted against Sony Mobile, can you describe the 22 investigation that you performed? 23 A. Sure. So for Sony Mobile, I reviewed the Sony 24 Mobile documentation and the source code from Qualcomm 25 associated with that. Page 157 1 Q. If we take a look at the '211, Claim 5, it 2 appears similar to the Claim 5 of the '326 patent we 3 were discussing earlier, correct? 4 A. Correct. 5 Q. But are there any differences? 6 A. There's a subtle difference. As you all heard 7 earlier, we're now talking about the receiver side, so 8 we have the base station sending us a signal, the 9 receiver gets the signal in its antenna. 10 11 12 13 So we now use a decoder instead of an encoder. Q. So what does the Claim 5 of the '211 patent require? A. So I've highlight -- highlighted some of the 14 requirements here. 15 about, again, those orthogonal codes and orthogonal code 16 generator, and now we have a first decoder. 17 In the top part, we're talking Later on in the claim, we have the overlay 18 portion where the claim discusses an overlay code, an 19 overlay code generator, and a second decoder. 20 Q. Now, does the -- does the same construction of 21 overlay code apply to the '211 patent that it did for 22 the patents asserted against the base station 23 manufacturers? 24 A. Yes, it does. 25 Q. And what is that construction? Page 158 1 2 A. That the overlay code is an additional code that subdivides an orthogonal channel. 3 Q. Now, the requirements for the handset side, in 4 other words, the '211 patent side, are they the same as 5 for the transmitter side? 6 A. The requirements for what? 7 Q. For the codes. 8 A. For the codes. 9 For the codes, yes, they're the same codes that the transmitter sends, because it's 10 the only way the other side can understand. 11 that's been encoded, you use the same key to decode it. 12 So we're still talking about these OVSF codes. 13 14 Q. Something Now, do the Sony Mobile phones have an overlay code? 15 A. No, they do not. 16 Q. Well, what do they have? 17 A. They have a single OVSF code per channel as 18 19 20 21 required by the standards. Q. And is that because, like you were saying, you have to use the same codes on both sides? A. Right. In order to sync up and hear what the 22 person from the other side is saying from the cell phone 23 tower, you need to have the same code on both sides. 24 Q. And how do you know which code to use? 25 A. It's been assigned to a channel. Page 161 1 both you and Dr. Wicker on a number of points. 2 putting the '211 patent to the side, the one that 3 relates to the mobile phones, is it fair to say that you 4 and Dr. Wicker essentially have the same opinions with 5 respect to the reasons why the Ericsson and 6 Alcatel-Lucent base stations do not infringe the base 7 station patents? 8 9 A. I don't know all of his opinions. And with The only ones I know are the ones that he presented here today. 10 Q. And you agree with those, right? 11 A. I'm sorry? 12 Q. And you agree with those? 13 A. Yes, I agree with those. 14 Q. And those are the ones you went through in 15 your testimony, right? 16 A. That is correct. 17 Q. All right. Now, so you agree with Dr. Wicker 18 that in the definition of overlay code, when it says 19 additional, that the Court's claim construction means 20 separate, correct? 21 A. I agree with Dr. Wicker that the Court's claim 22 construction, when you apply ordinary meaning to it, it 23 requires a separate code. 24 25 Q. All right. And, again, like Dr. Wicker said when he was on the stand, if the jury disagrees with Page 162 1 your reading of that term, then the jury's free to 2 disregard your opinions, correct? 3 A. The opinions regarding the overlay code, yes. 4 Q. Now, Dr. Wicker also, I believe, said this 5 morning that you could use the same hardware and 6 software to provide a first encoder and a second encoder 7 for an orthogonal code generator and overlay code 8 generator. 9 10 11 12 13 Do you remember that testimony? A. I think you're confused. I don't understand your question. Q. All right. Do you remember the testimony about the first encoder and the second encoder? 14 A. Yes, I do. 15 Q. All right. You remember the testimony about 16 the orthogonal code generator and the overlay code 17 generator, right? 18 A. Yes, I do. 19 Q. All right. Now, there was testimony about 20 whether those have to be separate; in other words, 21 separate hardware, separate software for the first 22 encoder and the second encoder. 23 24 25 A. Okay. So we're talking about the first encoder and second encoder? Q. Correct.
