WORD TO INFO INC, Plaintiff,
GOOGLE INC., Defendant.




         Plaintiff Word to Info, Inc. ("WTI") brings these two separate lawsuits - one against defendant Facebook Inc. ("Facebook") (No. 15-cv-03485-WHO) and the other against Google Inc. ("Google") (No. 15-cv-03486-WHO) - accusing both defendants of infringing the same seven patents, United States Patent Nos. (1) 5, 715, 468 ("the '468 patent"); (2) 6, 138, 087 ("the '087 patent"); (3) 6, 609, 091 ("the '091 patent"); (4) 7, 349, 840 ("the '840 patent"); (5) 7, 873, 509 ("the '509 patent"); (6) 8, 326, 603 ("the '603 patent"); and (7) 8, 688, 436 ("the '436 patent").

For the reasons discussed below, WTI's motions to amend are GRANTED, and Google's motion to strike WTI's original infringement contentions is DENIED AS MOOT.


         I.WTI v. FACEBOOK

         A. Basic Procedural History

         WTI initiated its action against Facebook on December 14, 2015 in the United States District Court for the Northern District of Texas. Dkt. No. 1. On May 8, 2015, WTI served Facebook with infringement contentions pursuant to the Northern District of Texas's Amended Miscellaneous Order No. 62, paragraph 3-1, which the parties describe as "substantively similar" to this district's Patent Local Rule 3-1. Joint Case Management Statement at 2-3, 13 (Dkt. No. 69). On July 23, 2015, the case was transferred to this district. Dkt. No. 49. The parties have since continued to treat the infringement contentions served on May 8, 2015 as the operative infringement contentions in the case.

         During the initial case management conference on November 10, 2015, I set a schedule for reducing the asserted claims and prior art references, requiring (1) WTI to preliminarily elect no more than 10 claims per patent and 32 claims in total by December 14, 2015, and then to finally elect no more than 5 claims per patent and 16 claims in total by 28 days after the claim construction ruling; and (2) Facebook to preliminarily elect no more than 18 references per patent and 50 references in total by February 5, 2016, and then to finally elect no more than nine references per patent and 25 references in total by 14 days after WTI's final election of asserted claims. Dkt. No. 73.

         At the end of the case management conference, Facebook asked to confirm "that in the December date when we get the reduction in claims, it's a full citation to the code that they've had access to, these are final contentions at this point, . . . that's what your Honor is anticipating."[1]Hearing Tr. at 21 (Dkt. No. 78). I stated, "Under the local rules, that's what I'm anticipating." Id. WTI added, "Final except for leave to amend with good cause, " and I responded, "Right." Id.
