SUE L. ROBINSON, District Judge.
At Wilmington this 23rd day of May, 2013, having considered defendant Texas Instruments, Inc.'s ("TI's") motion for leave to file an amended answer and the papers submitted therewith;
IT IS ORDERED that said motion (D. I. 128) is denied, as follows:
1. Background. Plaintiff Cradle IP, LLC ("Cradle") filed this action against Tl on December 16, 2011, accusing a number of Tl's microprocessor chips and devices (the "accused devices") of infringing three patents, including United States Patent No. 6, 647, 450 ("the '450 patent"). (D.I. 1) Tl filed its answer on February 6, 2012. (D.I. 12) In response to allegations related to the '450 patent, paragraph 19 of the answer states:
19. Tl admits that it does or has made, manufactured, used, sold, or offered to sell microprocessor and OMAP devices utilizing split transaction buses with target device command buffers (insofar as that phrase is given its common meaning and not necessarily the meaning that may be ascribed to it as a result of any claim construction), including devices AM389xSitara ARM Microprocessors, OMPA34xx devices, OMPA35xx devices, OMAP36xx devices, and OMAP4xxx devices if "xx" or "xxx" means a combination of numbers and letters unspecified. Tl denies the remainder of the allegations contained in Paragraph 19 of the Complaint.
(D.I. 10 at ¶ 19) (emphasis added) The phrases "split transaction buses" and "target device command buffers" do not appear in any claim of the '450 patent, although the terms "split transaction global bus" and "command FIFO" do.
2. On August 16, 2012, Tl responded to Cradle's second set of interrogatories with a non-infringement contention that the accused OMAP devices do not perform the limitations recited in claim 22 of the '450 patent, including "a) sending a command from a master device to a split transaction global bus" or "b) placing the command in a command FIFO of a target device." (D.I. 130, ex. Cat 9, 11, 13, 14, 16) On September 13, 2012, Tl responded to Cradle's amended first set of interrogatories by stating, in part, that "there are no Tl products that are multi-processor systems with split-transaction bus systems where such systems have command buffers in target devices, including but not limited to split-transaction bus systems that utilize Open-Core Protocol or any protocol that requires generating an acknowledgement that commands are received." ( Id., ex. D at 8)
3. Tl now proposes to amend paragraph 19 of its answer to read:
19. Tl admits that it does or has made, manufactured, used, sold, or offered to sell microprocessor and OMAP devices, including devices AM389xSitara ARM Microprocessors, OMPA34xx devices, OMPA35xx devices, OMAP36xx devices, and OMAP4xxx devices if "xx" or "xxx" means a combination of numbers and letters unspecified, but denies that its OMAP devices utilize split transaction buses with target device command buffers. Tl denies the remainder of the allegations contained in Paragraph 19 of the Complaint.
(D.I. 128, ex. A at ¶ 19) (emphasis added) Tl first contacted Cradle on December 4, 2012 with its request to amend the answer. (D. I. 130, ex. E) The parties then conferred but could not reach an agreement on Tl's proposed amendment. ( See id., exs. F, G, H, I, J, K) Tl filed the motion for leave to amend its answer on January 23, 2013. (D.I. 128)
4. Standard. The Federal Rules of Civil Procedure require courts to freely give leave to amend "when justice so requires." Fed.R.Civ.P. 15(a)(2). The court may exercise its discretion to deny leave to amend in situations in which the moving party has delayed seeking leave and the delay "is undue, motivated by bad faith, or prejudicial to the opposing party." Bjorgung v. Whitetail Resort, LP, 550 F.3d 263, 266 (3d Cir. 2008) (citation omitted). After a pleading deadline has passed, courts have required the movant to also satisfy the more rigorous "good cause" standard of Federal Rule of Civil Procedure 16(b)(4). See, e.g., ICU Med. Inc. v. RyMed Techs., Inc., 674 F.Supp.2d 574, 577-78 (D. Del. 2009); Cordance Corp. v. Amazon.com, Inc., 255 F.R.D. 366, 371 (D. Del. 2009).
5. Discussion. Tl contends that the proposed amendment will conform its answer to its interrogatory responses and ensure that Cradle cannot characterize paragraph 19 to the jury as an admission of infringement. (D. I. 129 at 1-2) Cradle opposes the motion on grounds of undue delay and prejudice. Specifically, it asserts that Tl's delay in seeking amendment is undue because the proposed amendment contravenes the scheduling order without explanation. (D.I. 150 at 6-7) With respect to prejudice, Cradle argues that permitting the amendment would amount to allowing Tl to retract an admission and would require the reopening of fact discovery. (/d. at 7-9)
6. Undue delay. Tl posits that its delay would not place an unwarranted burden on the court or Cradle because it put Cradle on notice of its proposed amendment before any depositions occurred and before the close of fact discovery. (See D.l. 170 at 3-4) However, the consideration of undue delay "requires that [the court] focus on the movant's reasons for not amending sooner." Cureton v. Nat'l Collegiate Athletic Ass'n, 252 F.3d 267, 273 (3d Cir. 2001); see also Bjorgung, 550 F.3d at 266. Tl's motion was filed on January 23, 2013, more than two months after the November 1, 2012 deadline for the amendment of pleadings as set by the scheduling order. (D.I. 16) Tl asserts that it contacted Cradle on December 4, 2012 with a draft of its proposed amended answer after discovering that paragraph 19 of its original answer might be interpreted inconsistently with its discovery responses and non-infringement contentions. (D.I. 129 at 5; D. I. 130, ex. E) Although this assertion explains why Tl now seeks to amend, it does not explain why Tl did not seek to amend before the expiration of the deadline to amend pleadings. The proposed amendment is not based on any new evidence that has emerged during discovery. Rather, paragraph 19 relates to information that has been in Tl's possession all along, and Tl does not contend that the structure of the accused devices has changed since it filed the answer. ( See D.I. 130, ex. G) Given the lack of proper justification, Tl's delay is undue.
7. A finding of undue delay, without a finding of prejudice, may justify denial of a motion to amend "when the amendment is grounded on bad faith or dilatory motive, truly undue or unexplained delay....'" lnline Connection Corp. v. AOL Time Warner Inc., 237 F.R.D. 361, 369 (D. Del. 2006) (quoting Heyl & Patterson lnt'l, Inc. v. F.D. Rich Housing of the Virgin Islands, Inc., 663 F.2d 419, 425 (3d Cir. 1981)). Courts in this circuit have denied motions to amend based solely on undue delay when a long delay was unexplained. See Lorenz v. CSX Corp., 1 F.3d 1406 (3d Cir. 1993) (affirming denial to amend where the district court made no finding of prejudice but leave to amend was filed nearly two years after the prior amendment); USX Corp. v. Barnhart, 395 F.3d 161 (3d Cir. 2004) (affirming denial of leave to amend on the ground of unreasonable delay where the movant waited more than three years to amend). Here, Tl notified Cradle of its desire to amend approximately one month after the deadline and then filed its motion to amend approximately one and a half months later. Although the court finds that there is undue delay, the delay in this ...
