Opinion

DSS TECHNOLOGY MANAGEMENT, Case No. 14-cv-05330-HSG INC., ORDER ON DSS'S MOTION TO Plaintiff, AMEND INFRINGEMENT CONTENTIONS AND APPLE'S v. CROSS-MOTION TO STRIKE APPLE, INC., REDACTED VERSION Defendant. Re: Dkt. Nos. 213, 215, 219, 220, 231, 233, 246 Pending before the Court is DSS’s motion to amend infringement contentions, Dkt. Nos., 215 (“Mot.”), 220 (“Opp./XMot.”), 232 (“Reply”), and Apple’s cross-motion to strike DSS’s infringement expert report, Dkt. Nos. 220, 234 (“XOpp.”), 249 (“XReply”). The parties also filed related motions to seal portions of its briefs and accompanying exhibits. Dkt. Nos. 213, 219, 231, 233, 246. For the reasons provided below, the Court DENIES DSS’s motion to amend infringement contentions and GRANTS Apple’s cross-motion to strike DSS’s infringement expert report.1 Plaintiff DSS Technology Management, Inc. filed its complaint against Defendant Apple, Inc. on November 26, 2013, in the Eastern District of Texas, alleging infringement of U.S. Patent Nos. 6,128,290 (the “’290 patent”) and 5,699,357 (the “’357 patent”). Dkt. No. 1. DSS later withdrew all infringement allegations as to the ’357 patent, so presently only the ’290 patent is at issue. SeeDkt. No. 96 at 2, 4. DSS alleges that Apple’s development and sale of computers and 1 other devices (iMacs, Mac Minis, Mac Pros, iPhones, iPads, and iPods) that provide wireless 2 Bluetooth connections to peripheral devices (such as keyboards and mice) infringes the ’290 3 patent. Specifically, DSS alleges that the ’290 patent “solved the problem of how to connect 4 peripherals wirelessly to a computer but still have sufficient battery life to be practical.” Mot. at 6. 5 This was achieved by “a communication scheme whereby the computer would place the 6 peripheral[ devices] on a schedule as to when the devices might periodically communicate with 7 the computer.” Jd. As opposed to keeping the Bluetooth transmitter in these peripheral devices 8 always on, this “low duty cycle” reduced the peripheral devices’ battery power consumption by 9 turning the transmitter on for only short periods. There are two modes in which a device may 10 operate to effectuate this “low duty cycle:” Bluetooth Sniff Mode and Sniff Subrating Mode. Dkt. 11 No. 213-7 at 129. Both reduce battery power consumption by negotiating periods of time when 12 the peripheral device’s Bluetooth transmitter turns back on. Jd. Sniff Subrating Mode “further 13 reduc[es] the active duty cycle” and saves power by specifying lower maximum access points. 14 Jd? Bluetooth Sniff Subrating Mode is an optional functionality. Jd. at 668. 15 On March 13, 2014, DSS served initial Preliminary Infringement Contentions (“PICs”) on 16 Apple. See Dkt. No. 214-1 (Mot. Ex. 15). After correspondence with Apple, DSS served 17 || Amended PICs on May 2, 2014, which added information about the accused products. Dkt. No. Zz 18 214-3. The contentions contain three claim charts—only Exhibit B (for the ’290 patent for “Apple 19 Bluetooth v4.0 Products”) and Exhibit C (for the ’290 patent for “Apple Bluetooth v2.1 Products’’) 20 are atissue. Dkt. No. 215-18 (Ex. B, Ex. C). Exhibit B states that “[t]his particular set of 21 Preliminary Infringement Contentions maps Apple’s products that make use of the Bluetooth 4.0 22 standard... for wireless communications between a device and its peripherals to the claims of . . . 23 the 290 patent.” Jd. Ex. B at 1. Similarly, Exhibit C states that “[t]his particular set of 24 Preliminary Infringement Contentions maps Apple’s products that make use of versions of the 25 Bluetooth standards between versions 2.1 . . . and 4.0 for wireless communications between a 26 27 lo... we a . .
