`
`I would like to schedule a meet and confer to discuss next steps regarding the
`identification of representative products.
`
`In Ii ht of the Federal Circuit’s recent decision
`
`reserves the right to update its position for any reason, including in the event that this
`Court (or any court of appeal) adopts a different construction of the “substantially
`flexible” claim terms.
`
`In order to move forward with the selection of representative products, I would like to
`discuss the following issues:
`
`1. Whether Samsung has already identified all products sold between 2008 and
`2018 that meet the above criteria.
`
`2. How the parties will handle the Samsung semiconductor products for which
`Samsung has not, to date, supplied complete die thickness data.
`
`3. How the parties will select representative products from the complete set of
`accused products.
`
`Please let me know if there is a time early next week when you are available to discuss
`these issues.
`
`In addition, it’s been almost a month since I sent the below email, but have not
`received any meaningful response. Please let us know your thoughts on the below
`issues this week.
`
`Thanks,
`

` I
`
` 
`
`
`
` am surprised to hear that you believe you’ve produced your supplier
`documents. From what I can see, your April 22 production contained no email. For
`many months, we’ve been asking for your communications with your dielectric
`suppliers about dielectric stress. Will you be producing those?
`
`Relatedly, your April 22 production is missing the standard metadata. Can you please
`provide an overlay with that information?

`Nosson,  
`
`We provide some comments to your email below.  
`
`For the first category of V‐NAND products that you have raised below, the examples you provided do not persuade us 
`that Samsung’s list of stacked die products is incomplete.  
`
`You refer to V‐NAND products with multiple “layers,” but we are not convinced that “layers” mean “stacks” of chips, as 
`you seem to be reading this term.  For example, page 3 of the white paper that you cited states in part: “NAND flash 
`capacity is determined by the number of memory cells that can populate a NAND chip” and “The 32‐layer stacks of cells 
`are connected to over 2 billion channel holes that have been etched from the top layer of the NAND to the 
`bottom.”  The following webpage also explains that stacked “chips” is entirely distinguishable from NAND “layers,” such 
`that one single chip can contain multiple such layers: https://thememoryguy.com/nand‐flashs‐layers‐of‐layers‐of‐
`layers/.  In contrast, we have identified products with stacked chips.  Thus, we don’t agree that a publication paper 
`describing V‐NAND products with 24 or 32 layers suggests that Samsung has failed to disclose additional stacked 
`products with more than 16 stacked chips.      
`
`As for your second example below, we are surprised that Elm is raising image sensor products for the first time at this 
`late stage, when the parties have been treating this case as directed to stacked memory products for several years 
`now.  Given that, we do not believe that your suggestion that Samsung has been misleading or not diligent in providing a 
`complete list of stacked die products is justified.  If Elm believes now that image sensor products should be added to the 
`case, we would appreciate more reasonable time for investigation than the very short notice that you have given us to 
`identify an entirely new category of products.   
`
`Given the seriousness of Elm’s apparent attempt to substantially expand the scope of this case, we believe it would only 
`be fair if, in the meantime, Elm amends its infringement contentions so that they provide Samsung more meaningful 
`notice of Elm’s theory of infringement with respect to the new image sensor products.  We believe that amended 
`infringement contentions would be especially instructive here given the issue above with respect to multiple layers or 
`chips, and Elm’s confusing use of terms recently, e.g., semiconductor “layer” instead of “substrate,” or stacked 
`“semiconductor product” instead of “memory product” (see Elm’s Common Interrogatory Nos. 4‐5).  At the very least, 
`Samsung is entitled to a full understanding of Elm’s bases for why it believes that image sensor products are reasonably 
`similar to the stacked memory products accused to date.   
`
`Therefore, please confirm that if it is Elm’s intention to add image sensor products to the case Elm will amend its 
`infringement contentions accordingly.

` 
`Soyoung,
`
`Your email asserts that Samsung has already provided a complete list of all stacked
`semiconductor products sold from 2008 to the present that Samsung knows to contain
`more than one circuit layer, where at least one circuit layer is stacked above or below
`another circuit layer, and where at least one of the layers has a thickness of 50µm or
`less. We fear that this is simply not true and is, instead, another disturbing example of
`Samsung seeking to gain a litigation advantage through obfuscation and
`concealment.
`
`One example of the possible gaps in the data Samsung has provided to date relates to
`Samsung’s V-NAND products. According to the following white paper-- 
`https://www.samsung.com/semiconductor/global.semi.static/2bit V-
`NAND technology White Paper-1.pdf -- Samsung has been producing V-NAND
`memory products with 24 layers since 2013, and with 32 layers since 2014. The
`largest stack that Samsung has identified to us in this case is 16 layers. So it’s clear
`that these V-NAND products have not been identified in discovery. Given the number
`
`2
`
`

`

`Case 1:14-cv-01430-LPS Document 380-1 Filed 11/30/20 Page 9 of 86 PageID #: 24041
`
`of layers in these products. we believe it is highly likely that at least one of the layers is
`50pm or less.
`
`Another example of a possible gap in the data Samsung has provided relates to
`camera chips included in Samsung‘s Galaxy phones. We understand that. at least as
`of 2016. Samsung‘s phones have included an image sensor chip stacked. via TSVs.
`with a DRAM memory chip. None of the products Samsung has identified in the
`litigation appear to include an image sensor chip stacked with DRAM Given the
`nature of the image sensing technology used in Samsung‘s phones we believe it is
`highly likely that at least one of the chips in these products has a thickness of 50pm or
`less.
`
`Please let us know why these products have not been identified to us in litigation to
`date,
`
`
` Please let us know whether Samsung has any other
`
`
`
`recommendations for how to move forward with these products.
`
`Thanks.

`Nosson,
`
`In response to this and your previous email, Samsung has identified all products that you have asked about based on a
`reasonable search. You have not given any basis for your suspicion that the list of products that Samsung has identified
`
`is incomplete.
`
`In any event, we will forward this spreadsheet on for Samsung to review.

`
`Further, we have repeatedly informed you that Samsung does not have the requested thickness information. Whether
`that is difficult for you to believe is irrelevant to the fact that this information has not turned up after months of
`
`Samsung’s diligent searches.
`
`Finally, we ask that you propose preliminary suggestions for addressing products for which no thickness information
`exists and arriving at a list of representative products. We believe that this is Elm’s burden, not Samsung’s. Otherwise,
`
`we don’t think that we will make much progress on these issues or that a call would be very productive at this point.

`
`Soyoung,
`
`Following—up on the below email, and given your failure to offer any time to talk, we
`wanted to email you some additional details about the information we’re seeking from
`Samsung. In that vein, I’ve attached a spreadsheet that contains the following data:
`
`1. Column A: Pre-stay products missing thickness data: This lists the more than
`200 Samsung products identified in Elm's June 3, 2016 identification of accused
`products for which Samsung has not produced die thickness data.
`
`2. Column B: Pre-stay products that contain one die at 50pm or less: This lists the
`18 Samsung products included in the pre-stay identification of accused products
`that Elm provided on June 3, 2016, and that the ’43 spreadsheet indicates have
`at least one die at 50pm or less (note that this list is a subset of the 50 products
`identified in Column D).
`
`
`
`4. Column D: Post—stay products that contain one die at 50pm or less: This lists the
`50 Samsung products identified in the ’42 and ’43 spreadsheets as including at
`least one die that is 50pm or less.
`
`We would like Samsung to let us know, this week, whether Column D in the attached
`spreadsheet lists every Samsung semiconductor product sold from 2008 to the present
`that Samsung knows to contain more than one circuit layer, where at least one circuit
`layer is stacked above or below another circuit layer, and where at least one of the

`incomplete, please also let us know when Samsung will be able to complete this list. If
`Samsung cannot commit to a reasonable timeframe in which to complete this list, then
`we intend to raise this issue with the Court.

`Subject: RE: Elm Discovery Correspondence
`
`Soyoung,
`
`I would like to schedule a meet and confer to discuss next steps regarding the
`identification of representative products.
`
`In light of the Federal Circuit’s recent decision, Elm currently intends to accuse of
`infringement all Samsung semiconductor products that contain more than one circuit
`layer, where at least one circuit layer is stacked above or below another circuit layer,
`and where at least one of the layers has a thickness of 50 microns or less. Elm
`reserves the right to update its position for any reason, including in the event that this
`Court (or any court of appeal) adopts a different construction of the “substantially
`flexible” claim terms.
`
`

`

`Case 1:14-cv-01430-LPS Document 380-1 Filed 11/30/20 Page 14 of 86 PageID #: 24046
`In order to move forward with the selection of representative products, I would like to
`discuss the following issues:
`
`1. Whether Samsung has already identified all products sold between 2008 and
`2018 that meet the above criteria.
`
`
`
`
`
`2. How the parties will handle the Samsung semiconductor products for which
`Samsung has not, to date, supplied complete die thickness data.
`
`3. How the parties will select representative products from the complete set of
`accused products.
`
`
`
`Please let me know if there is a time early next week when you are available to discuss
`these issues.
`
`In addition, it’s been almost a month since I sent the below email, but have not
`received any meaningful response. Please let us know your thoughts on the below
`issues this week.
`
`
`Thanks,
`

`Soyoung,

`
`
` 
`
` I
`
` am surprised to hear that you believe you’ve produced your supplier
`documents. From what I can see, your April 22 production contained no email. For
`many months, we’ve been asking for your communications with your dielectric
`suppliers about dielectric stress. Will you be producing those?
`
`Relatedly, your April 22 production is missing the standard metadata. Can you please
`provide an overlay with that information?

`Re: Elm 3DS Innovations, LLC v. Samsung Elecs. Co. Ltd., et al.,
`C.A. No. 14-cv-1430-LPS-CJB, D. Del.
`
`
`
`Dear Counsel,
`
` In the hopes of ensuring a productive conversation on Tuesday, this letter provides a more
`detailed description of the minimal discovery commitments that Elm expects Samsung to make
`during that conversation. Nothing in this letter is intended to limit the scope of any pending
`discovery requests. Nor should this letter be construed as a commitment from Elm not to pursue
`additional discovery on any issue. Instead, this letter is intended to help guide the conversation and
`to put Samsung on notice that, if it refuses to commit to provide discovery substantially along the
`lines outlined in this letter, Elm intends to immediately move to compel.
`
`Samsung must immediately provide the information it committed to provide on
`August 1. After our July 30 meet and confer, I sent you an email outlining the middle ground
`approach I proposed in order to avoid immediately filing a motion to compel. You agreed to that
`approach but, since then, have failed to hold up your end of the deal. In particular, you agreed to
`“investigate the die thickness issue,” said that you expected to “provide to Elm a complete list of all
`multi-layer semiconductor products that contain a layer that is 50 microns or less within the next
`two to three weeks,” and agreed to “promptly produce US sales data for any such products” that
`were not listed in the spreadsheet I had sent you.
`
`Although a month has passed, you have not provided us a complete list of all such products,
`or sales data for them. Samsung must commit to provide that list no later than Friday, Sept. 6, and
`provide US sales data for any such products that were not included in the Samsung-Elm-000062354
`spreadsheet no later than Friday, Sept. 13.
`
`In order to avoid any disagreements about the propriety or scope of these updates, Elm
`provides the following notes explaining what the September 6 and 13 updates must entail:
`
` •
`
` These updates will include every Samsung memory product that contains more than one
`die, where at least one die is stacked above or below another die, and where at least one
`of the die has a thickness of 50 microns or less.
`
`

`Samsung is providing.

`the present that Samsung knows to contain more than one circuitlayer, Wh
