`
`dates.3 See 157 Cong. Rec. S5429 (Sept. 8, 2011) (Sen. Kyl) (“High-technology
`
`companies … are often sued by defendants asserting multiple patents with large
`
`numbers of vague claims, making it difficult to determine in the first few months of
`
`the litigation which claims will be relevant. . . . [I]t is important that the section
`
`315(b) deadline afford defendants a reasonable opportunity to identify and
`
`understand the patent claims that are relevant to the litigation.”)
`
`Factor 3 – The Court has little substantive investment: Apart from the
`
`Markman proceedings, the district court has not invested other substantive efforts
`
`and the litigation is not “advanced.” Summary judgment is still months away, and it
`
`is unlikely the court will tackle invalidity until trial. Fact discovery and depositions
`
`are ongoing. The bulk of the parties’ work lies ahead. See IOENGINE at *14.
`
`Nor did the litigation give Apple a tactical advantage. Because Maxell did not
`
`substantively respond to Apple’s invalidity contentions, Apple could not have used
`
`any substantive insight gained in the litigation in its IPR filings. (Paper 11, at 12.)
`
`
`3 Maxell argues it served Apple with a letter identifying the challenged patent on
`
`May 17, 2018. That letter (Ex. 2001) listed 80 different patents and 647 possible
`
`claims. Maxell’s suggestion that this letter should be part of this analysis is patently
`
`unreasonable.
