6 LINKSMART WIRELESS TECHNOLOGY, Case No. 2:18-cv-00862-MMD-NJK LLC, 7 ORDER Plaintiff, 8 v.

9 GOLDEN NUGGET, INC., et al.,

10 Defendants. 11 12 I. SUMMARY 13 Plaintiff Linksmart Wireless Technology, LLC alleges that Defendants Golden 14 Nugget, Inc., Landry’s Inc., Las Vegas Sands Corp., and MGM Resorts International1 15 infringe U.S. Reissued Patent No. RE46,459 (ECF No. 1-1 (the “’459 Patent”))2 in this 16 consolidated patent case3 because they have systems at their hotels that ask guests for 17 login information the first time those guests connect to the WiFi. (ECF No. 1.) Before the 18 Court are: (1) Defendants’ motion to strike the infringement expert report of Plaintiff’s 19 expert Mr. Erik de la Iglesia (ECF No. 204 (“Defendants’ Motion”)); (2) Plaintiff’s motion to 20 strike at least portions of invalidity expert reports from Defendants’ expert, Mr. Ed Tittel 21 (ECF No. 212 (“Plaintiff’s Motion”)); and (3) two unopposed motions to seal (ECF Nos. 22 23 1Defendants Caesars Entertainment Corporation and Wynn Las Vegas LLC settled. 24 (ECF No. 213.) The Court granted a joint stipulation to dismiss them on March 15, 2021. (ECF No. 232.) Thus, this order does not refer to them, though some of the briefs either 25 refer to them or initially included them.

26 2The ’459 Patent reissued from U.S. Patent No. 6,779,118. (ECF No. 110 at 5.)

27 3The Court consolidated Case Nos. 2:18-cv-00864-MMD-NJK, 2:18-cv-00865- MMD-NJK, 2:18-cv-00867-MMD-NJK, and 2:18-cv-00868-MMD-NJK under this case. 28 1 205, 216).4 As further explained below, the Court will grant Defendants’ Motion primarily 2 because Mr. de la Inglesia offers opinions not disclosed in Plaintiff’s initial infringement 3 contentions, and instead based on amended infringement contentions the Court already 4 struck, deny Plaintiff’s Motion because Mr. Tittel’s supplemental report does not violate 5 the applicable timeliness rules, and he offers opinions in his opening report fairly disclosed 6 in Defendants’ infringement contentions, and grant the unopposed motions to seal 7 because the parties have proffered compelling reasons to grant them. 8 II. BACKGROUND 9 The Court incorporates by reference the relevant factual background provided in 10 the Court’s claim construction order, and does not recite it here. (ECF No. 137 (“Claim 11 Construction Order”) at 1-3.) As pertinent to these motions, in the Claim Construction 12 Order, the Court construed the term “redirection server” to mean “a server configured to 13 redirect a user to a location on the public network that is different from the network location 14 in the user’s request[.]” (Id. at 5-10.) This is the construction advanced by Defendants, not 15 Plaintiff. (Id.) 16 On Defendants’ motion, the Court recently struck Plaintiff’s amended infringement 17 contentions for noncompliance with LPR 1-12, and alternatively because Plaintiff did not 18 show the diligence required for Plaintiff to obtain the Court’s leave to file amended 19 infringement contentions, had Plaintiff sought such leave. (ECF No. 203 (“Prior Order”).) 20 The Court issued the Prior Order on January 20, 2021. (Id.) 21 Meanwhile, the parties were preparing and serving expert reports. As pertinent 22 here, Plaintiff served Mr. de la Inglesia’s expert report on infringement on January 7, 2021. 23 (ECF No. 207 (sealed) at 3.) On that same day, Defendants served Mr. Tittel’s invalidity 24 expert report. (ECF No. 212-4 at 35.) On January 15, 2021, Defendants served a 25 supplemental expert report authored by Mr. Tittel. (ECF No. 212-5 at 3.) Defendants move 26

27 4The Court reviewed the corresponding responses, replies, and accompanying 28 1 to strike Mr. de la Inglesia’s report in its entirety, and Plaintiff moves to strike Mr. Tittel’s 2 initial report in part, and his supplemental report in its entirety. (ECF Nos. 204, 212.) 3 III. DISCUSSION 4 The Court first addresses Defendants’ Motion, then Plaintiff’s Motion, and then the 5 pending motions to seal. 6 A. Defendants’ Motion 7 Defendants argue the Court should strike Mr. de la Inglesia’s expert report because 8 it is based entirely on theories of infringement raised for the first time in the amended 9 infringement contentions the Court struck in its Prior Order. (ECF No. 204 at 2.) 10 Defendants more specifically argue that Mr. de la Inglesia offers previously undisclosed 11 literal infringement opinions based on the Court’s construction of “redirection server,” and 12 theories based on the doctrine of equivalents also not disclosed in Plaintiff’s operative 13 infringement contentions. (Id.) Plaintiff counters that its infringement theory has never 14 changed. (ECF No. 216-2 (sealed) at 5-6.) As to Defendants’ literal infringement argument, 15 Plaintiff argues it has always contended that Defendants infringe by redirecting users to 16 Defendants’ login portal page when those users attempt to connect to the internet. (Id.) As 17 to Defendants’ doctrine of equivalents argument, Plaintiff argues that Defendants’ 18 argument is inconsistent with Defendants’ arguments regarding their own invalidity report. 19 (Id. at 7.) The Court agrees with Defendants. 20 1. Doctrine of Equivalents 21 Beginning with the parties’ doctrine of equivalents arguments, Plaintiff’s argument 22 is largely beside the point. (Id. at 19-20.) The level of detail provided in Defendants’ 23 invalidity contentions is irrelevant to the question of whether the Court should strike the 24 portions of Mr. de la Inglesia’s expert report opining on infringement under the doctrine of 25 equivalents. Moreover, in response, Plaintiff acknowledges Defendants’ argument that 26 Plaintiff’s boilerplate reservation of rights as to the doctrine of equivalents in its operative 27 infringement contentions is insufficient, but then declines to address it. (Id. at 19.) 28 /// 1 More relevant to Defendants’ actual argument, Plaintiff does not dispute that the 2 only mention of the doctrine of equivalents in its initial, operative infringement contentions 3 is: “To the extent [Defendant] contends that other limitations are not literally infringed, 4 Linksmart asserts that the limitation is infringed under the doctrine of equivalents and 5 reserves the right to supplement these disclosures if and when [Defendant] makes such 6 contentions.” (Id. at 19.) This sentence appears at the beginning of Plaintiff’s infringement 7 contentions, and is not linked to any particular claim or claim limitation. (Id.; see also ECF 8 No. 189-12 at 4.) Plaintiff’s statement, which amounts to a reservation of rights to assert 9 the doctrine of equivalents, does not comply with LPR 1-6(e) (requiring a statement of 10 “[w]hether each limitation of each asserted claim is alleged to be literally present or present 11 under the doctrine of equivalents in the Accused Instrumentality”). Plaintiff also does not 12 dispute that Mr. de la Inglesia provides opinions that include specific, targeted applications 13 of the doctrine of equivalents throughout his report. (ECF Nos. 204 at 8 (providing several 14 references), 207 (sealed) at 114 n.23, 138-139, 140, 146, 152, 184 n.34, 202, 204, 208, 15 211, 243 n.46, 268-69, 271, 275-76, 278-79 (offering infringement opinions as to specific 16 claim limitations under the doctrine of equivalents), 216-2 (sealed) at 19-20 (declining to 17 dispute that Mr. de la Inglesia offers all of these specific doctrine of equivalents opinions).) 18 Thus, Mr. de la Inglesia is making specific doctrine of equivalents assertions Plaintiff did 19 not make in its operative infringement contentions.5 20 But the “purpose of requiring parties to disclose the basis for their contentions is to 21 make them explicit and streamline patent litigation.” Thought, Inc. v.
