Opinion

1 2 3 4 UNITED STATES DISTRICT COURT 5 NORTHERN DISTRICT OF CALIFORNIA 6 7 MLC INTELLECTUAL PROPERTY, LLC, Case No. 19-cv-03345-EMC

8 Plaintiff, ORDER GRANTING IN PART AND DENYING IN PART MICRON, 9 v. MICRON SEMICONDUCTOR, AND MICRON CONSUMER’S MOTIONS 10 MICRON TECHNOLOGY, INC., et al., TO DISMISS; AND FINDING IM FLASH’S MOTION TO DISMISS 11 Defendants. MOOT 12 Docket Nos. 33, 38, 39, 64s

13 14 The instant case is a patent infringement action. The plaintiff is MLC Intellectual 15 Property, LLC (“MLC”). MLC has sued Micron Technology, Inc. (“Micron”) and nine affiliated 16 entities, the bulk of which appear to be wholly-owned subsidiaries: 17 (1) Micron Consumer Products Group, Inc. (“Micron Consumer”). 18 (2) Micron Semiconductor Products, Inc. (“Micron Semiconductor”). 19 (3) IM Flash Technologies (“IM Flash”).1 20 (4) Lexar Media, Inc. (“Lexar”). 21 (5) Micron Semiconductor Asia Pte. Ltd. (“Micron Singapore”). 22 (6) Micron Europe, Ltd. (“Micron Europe”). 23 (7) Micron Japan, Ltd. (“Micron Japan”). 24 (8) Micron Memory Taiwan Co., Ltd. (“Micron Taiwan”). 25 26 1 IM Flash does not appear to be a wholly-owned subsidiary. See FAC ¶ 6 (alleging that IM Flash 27 “is a joint venture formed in 2006 with Intel Technologies . . . to manufacture NAND Flash 1 (9) Micron Semiconductor (Xi’an) Co., Ltd. (“Micron China”).2 2 The first four subsidiaries are based in the United States. The remaining five subsidiaries are 3 foreign companies. Micron and all subsidiaries shall hereinafter be referred to as the “Micron 4 Defendants.” According to MLC, the Micron Defendants infringe, directly and/or indirectly, the 5 ‘571 patent. 6 Currently pending before the Court are three motions to dismiss. The motions have been 7 filed by: (1) Micron; (2) Micron Semiconductor; and (3) Micron Consumer. These three 8 defendants shall hereinafter be referred to as the “Moving Defendants.” Micron Semiconductor 9 and Micron Consumer shall hereinafter be collectively referred to as the “Micron Subs.” 10 Having considered the parties’ briefs and accompanying submissions, as well as the oral 11 argument of counsel, the Court hereby GRANTS in part and DENIES in part the motions to 12 dismiss. 13 I. FACTUAL & PROCEDURAL BACKGROUND 14 As alleged in the operative first amended complaint (“FAC”), MLC is the owner of the 15 ‘571 patent. The patent is titled “Electronically alterable non-volatile memo with N-Bits per cell.” 16 The invention claimed in the ‘571 patent

17 generally relates to a multi-level electrically alterable non-volatile memory device that includes memory cells with more than two 18 predetermined memory states. The device can be programmed, in accordance with input information, to one of a predetermined 19 number of memory states. Each memory state has associated with it a reference voltage. A reference voltage can be selected based upon 20 the input information (i.e., desired memory state), and the reference voltage can be compared to a voltage of the memory cell. A control 21 signal is generated that indicates whether the cell has been programmed to the desired memory state. A programming signal 22 can be controlled by the status of the control signal. Controlling the application of the programming signal is based upon the selected 23 reference signal. 24 FAC ¶ 22. 25 MLC has sued both Micron and a number of affiliated entities for infringement of the ‘571 26

27 2 It is not clear from the operative first amended complaint (“FAC”) whether MLC also intended 1 patent. 2 Prior to filing the instant action, MLC filed a suit for infringement of the same ‘571 patent 3 against Micron only. This action – hereinafter referred to as MLC I – is still pending before Judge 4 Illston. See generally MLC I, No. C-14-3567 SI (N.D. Cal.). MLC I has been heavily litigated. 5 Judge Illston has conducted several claim construction hearings as well as hearings on several 6 summary judgment motions. During MLC I, MLC tried to expand the scope of the litigation in at 7 least two ways: (1) to add nine Micron subsidiaries as defendants and (2) to add new accused 8 products based on Design IDs beyond the 13 that were undisputedly at issue in MLC I. Judge 9 Illston rejected both of MLC’s attempts. 10 In particular, Judge Illston made the following rulings that are relevant to the instant case. 11 (1) Order on MLC’s motion to amend. In November 2018, shortly before the close 12 of fact discovery, MLC moved for leave to file a first amended complaint. MLC wanted to add 13 Micron’s subsidiaries to MLC I. See Docket No. 233 (motion). All of the subsidiaries were the 14 same as those in the instant case, except MLC did not mention Micron Taiwan and instead 15 referenced Micron Semiconductor B.V. See MLC I (Docket No. 233) (motion). As noted above, 16 it is not clear whether MLC intended to implicate Micron Semiconductor B.V. in the instant 17 action. See note 2, supra. 18 In January 2019, Judge Illston denied MLC’s motion to add Micron’s subsidiaries to MLC 19 I. She held that MLC’s proposed “amendment is not appropriate because [it] would cause Micron 20 undue prejudice and would create undue delay in this case”; in particular, “[t]he Court would have 21 to reopen fact discovery and set an entirely new pretrial schedule” if it were to permit the 22 amendment, plus the new defendants “would almost certainly file motions challenging the 23 pleadings and jurisdiction and venue, particularly since five of the proposed defendants are foreign 24 entities” and further “would likely seek to revisit claim construction and file additional summary 25 judgment motions.” MLC I (Docket No. 288) (Order at 2). Judge Illston added that, “[i]f MLC 26 wishes to pursue claims against the subsidiaries (which MLC has previously asserted was 27 unnecessary because MLC contends that Micron is liable for all allegedly infringing sales), MLC 1 (2) Order on MLC’s motion to compel discovery. In December 2018, after the close 2 of fact discovery, MLC filed a motion to compel discovery in MLC I. The motion was related to 3 Design IDs. Although MLC had claimed infringement based on specific Micron products, it 4 learned through discovery that Micron essentially “categorized” its products by Design ID. Thus, 5 a given Design ID would cover multiple products. 6 In its motion to compel, MLC asked Judge Illston to compel Micron to provide 7 information for “all Design IDs for MLC/TLC NAND Flash devices.” MLC I (Docket No. 258) 8 (Mot. at 1) (emphasis in original). According to MLC, the accused products in the case “were – 9 and always have been – all of Micron’s MLC and TLC NAND Flash products.” MLC I (Docket 10 No. 258) (Mot. at 3) (emphasis in original), and, although Micron had previously identified 13 11 Design IDs to cover the accused products, it now appeared that there were some additional Design 12 IDs. 13 Micron opposed the motion to compel, arguing that MLC had not, in fact, accused “all 14 MLC/TLC NAND Flash products” and that the only relevant products were those specifically 15 identified in MLC’s infringement contentions, all of which were covered by the 13 Design IDs. 16 MLC I (Docket No. 274-3) (Opp’n at 1) (arguing that “MLC’s repeated attempt to use motions 17 practice to obtain discovery on unaccused products (especially after the close of fact discovery) is 18 a waste of the Court’s and the parties’ resources[;] [n]ow is not the time to relitigate this case anew 19 based on new discovery requested by MLC for products it did not accuse of infringement”). 20 Micron also argued that MLC had not acted diligently to identify or accuse additional Micron 21 products. See MLC I (Docket No. 274-3) (Opp’n at 14). 22 In January 2019, Judge Illston denied MLC’s motion to compel discovery.
