They do not have transcripts.

I am pretty sure they don't have transcripts in the jury room, otherwise they
wouldn't need it to be read back to them

I think you are optimistic. They may want to rehear Dr Mitchell testimony to
make sure they understand what he said.
Or there may be a specific point two jurors don't recall the same and they try
to determine who is right.

These are two possibilities. I am sure there can be many more. The plain truth
is we don't know what is in their mind except that they have questions about the
key issue and are actively working to get answers.

That could be the case, but it is also possible that someone remembers something
from that testimony but others do not recall it and want clarification. It
could be either positive or negative.

I recently served on a jury on a criminal trial. The very first thing presented
was a transcript from a previous hearing. We were NOT given the transcript for
reference at deliberation time, but some of us had taken good notes of that
portion of the case. The verdict did, in fact, end up hanging on that very

After the verdict, the attorneys came in for a brief post-mortem (with our
assent) and someone asked why we weren't given the transcript. The prosecutor
said he did not even consider it because he did not think the defense attorney
would agree (I forget the reason he said it could/would be disallowed). The
defense attorney said she would not have objected - although given that we came
in with a verdict of guilty, largely based on that evidence, she may well be
inclined to object in such a situation in the future.

I have no idea if we could have asked for it to be read back to us; that never
came up.

Dr. Mitchell's Testimony

I hope what they ask to be read back includes the cross examination by Google

I'm a bit more optimistic than PJ about how much of it will make sense to the
jury. From their questions they seem to be able to focus in and can tell which
are the important details even if they don't have a technical understanding of
it. For example, they may not know the technical arguments about whether a
symbolic reference can be indirect, but they were able to realize that for the
purpose of the patent case it might have to be direct only and that they could
tell if it was direct or not in Android's instructions. That is a result that a
techie might not reach because of preconceived notions of the meaning of
"instruction contains a symbolic reference".

Reading over Mitchell's testimony vs Parr's and trying to keep the mindset of
not knowing what "simulation" and "pattern matching" really
mean, Mitchell does come across as trying to stretch the semantics a bit too
far. In particular his supermarket example doesn't work for me. He gives an
example of pattern matching in every day life to show that it is a form of
simulating. But people don't think of what they are doing when they plan their
trip through the aisles as "running a simulation". If anything, the
example shows how what people do is the simpler thing called "pattern
matching" and it is not the complicated-sounding thing called

On the other hand my optimism or someone else's pessimism or doubts will not
influence the jury decision one way or the other.

Maybe this is what they're looking for:
Looking at the ‘520 patent, claim 1.

Google: Fair to characterize the executable code as pattern matching?

Dr. Mitchell: Not exactly.

Google: There are patterns that appear in the dex bytecode that is analyzed?

Dr. Mitchell: There is a reputing pattern of four instructions.

[Shows the Java bytecode for those four instructions. Dr. Mitchell argues that they aren’t a repeating pattern.]

Google shows the next four lines and they are the same, just the arguments incremented by one. It repeats another few times just in this slide.

Google: Could this be analyzed using pattern matching?

Dr. Mitchell: Potentially.

Here's an interesting quote
Authored by: Anonymous on Thursday, May 17 2012 @ 08:38 PM EDT
Mitchell's testimony
Oracle: Do Dalvik instructions contain symbolic references?

Dr. Mitchell: Yes.

Dr. Mitchell: What are they?

Dr. Mitchell: The field indexes.

Oracle: But those are numbers, does it matter?

Dr. Mitchell: Not at all, a number can be a symbolic reference.

I must have missed that one before. It should be a clear and simple issue of whether these indexes are memory offsets, or if they are like hash lookups.

The jury want's to make sure Dr. Mitchell never teaches again

I think the jury is on to Dr. Mitchell. By asking for a read back, his
intellectual dishonesty gets highlighted for the world to see.
