CHRISTOPHER J. BURKE, Magistrate Judge.
At Wilmington, Delaware this
1. Here, Defendant has moved to strike Plaintiff's amended infringement contentions on the ground that such amendment was untimely. (D.I. 320 at 2; see also Default Standard for Discovery, Including Discovery of Electronically Stored Information ("ESI") at ¶ 4 n.3 (noting that initial disclosure of infringement contentions may be later supplemented); Fed. R. Civ. P. 26(e) (noting that, in general, a party must timely supplement its discovery-related responses if it learns that its prior responses are incomplete or incorrect)) The basis for Defendant's challenge (at least as Defendant articulated it in its briefing) is that in Plaintiff's amended infringement contentions, Plaintiff has for the first time identified new "product families" as accused products; Defendant argues that the late addition of these "dozens of additional product families" to the case will do damage to the case schedule and cause it prejudice. (D.I. 320 at 1 (emphasis omitted)) Plaintiff, for its part, responds that it has done no such thing. Instead, Plaintiff states that in its amended infringement contentions it did not identify new product families; instead, it merely identified "sub-families within the accused product families already identified." (D.I. 325 at 1 (emphasis in original))
2. As an initial matter, the Court agrees with Plaintiff that—with regard to issues of infringement and invalidity in this case—discovery relating to Defendant's products has proceeded on a product-family-by-product-family basis. Indeed, Defendant has repeatedly emphasized to the District Court that it is appropriate for the parties to make accusations on a product family basis, explaining that this is so because (at least for purposes of this case) products that are a part of each Defendant product family can be understood to share the same material underlying product architecture. (See, e.g., D.I. 178 at 1 (Defendant asserting that it "has referred to [its] product prior art on which it intends to rely by product family name,[] because each family is based on the same architecture, underlying RTL description, design rules, and circuit layouts" and noting that "[Plaintiff] itself has taken this approach in identifying accused products") (certain emphasis in original, certain emphasis omitted)); id. at 2 (Defendant emphasizing that it "has stated that it will produce documents regarding the products that [Plaintiff] has charted and/or identified by family name in its infringement contentions") (emphasis added); Transcript of June 18, 2019 Hearing at 10-11 ("[District Court]: So is it OK for [Plaintiff] to identify products then in the same manner in which you are identifying them? ... [Defendant's Counsel]: We have not objected. We've been providing discovery relating to the entire family, not because we say there's some deficiency in their naming of a product [on a] product[-]family basis.") (emphasis added); id. at 43 ("[District Court]: I'm good with the family. I'm just going to require that you [i.e., Defendant] identify, to the extent you've not already, you need to identify the family[.]") (emphasis added); id. at 45 (same))
3. Therefore, so long as there is sufficient record information to allow the Court to conclude that what Plaintiff has done in its amended infringement contentions is to merely identify products that fall within an already-identified Defendant product family (i.e., "sub-families")—as opposed to identifying new Defendant product families—then such amendment would not be untimely or otherwise problematic.
4. On this front, with regard to Plaintiff's amended contentions relating to United States Patent Nos. 8,081,026 (the "'026 patent") and 7,246,027 (the "'027 patent"), there is enough record evidence for the Court to conclude that the allegedly newly-added product families at issue (i.e., Amber Lake Y and Whiskey Lake) are not new product families, and instead are considered by Defendant to be product sub-families subsumed within a previously-identified family (i.e., the Skylake family). (D.I. 320, ex. 1 at 4-7, 15-17; D.I. 325, exs. 4-5) In that regard, Plaintiff has provided the Court with deposition testimony from Defendant's Rule 30(b)(6) witness and from another Defendant engineer confirming that this is correct. (D.I. 325 at 1; id., ex. 14 at 51-52; D.I. 358, ex. A at 67-68) Thus, Defendant's motion is DENIED as it relates to the identification of these sub-families.
5. However, with regard to Plaintiff's amended contentions relating to United States Patent Nos. 7,523,331 (the "'331 patent") and 7,247,552 (the "'552 patent"), the record is less clear. From the documents provided by the parties, it is hard for the Court to tell if what Plaintiff is referring to as product "families" and "sub-families" really are groupings that are considered by Defendant to be such families/sub-families.
6. Therefore, by no later than
