`R2 Solutions LLC v. Databricks, Inc.
`No. 4:23-cv-01147-ALM (E.D. Tex.)
`
`Re:
`
`
`Jessica:
`
`We are in receipt of Databricks’ document production served on July 16. As you know,
`P.R. 3-4 required Databricks to “produce or make available for inspection and copying …
`[s]ource code, specifications, schematics, flow charts, artwork, formulas, or other documentation
`sufficient to show the operation of any aspects or elements of [the] Accused Instrumentalit[ies]
`identified by the patent claimant in its P.R. 3-1(c) chart[s]….” P.R. 3-4(a).
`
`While it appears that Databricks has produced some open-source code for Spark and
`some alleged prior art systems, it does not appear that Databricks has produced any of its own
`source code. Please confirm that Databricks will make its source code available for inspection by
`no later than Tuesday, August 13. Otherwise, please let us know your availability to meet and
`confer in advance of bringing this issue to the Court.
`
`Finally, as you consider Databricks’ document collection and production deficiencies,
`please note the following categories of documents that R2 expects to see. The list below is not
`meant to be exhaustive; rather, R2 expects to receive a copy of “all documents, electronically
`stored information, and tangible things that are in the possession, custody, or control of
`[Databricks] relevant to the claims or defenses of any party.” See Order Governing Proceedings
`(ECF 18). As used herein, the term “document” includes all of the types of information described
`in FRCP 34, and the term “Databricks” includes Databricks and its affiliates.
`
`Categories
`
`1. Computer code (compiled or not, in any language, including SQL) for each Accused
`Instrumentality.
`
`2. All documents describing, illustrating, and/or summarizing computer code responsive
`to Category 1, above.
`
`3.
