1 2 3 4 UNITED STATES DISTRICT COURT 5 NORTHERN DISTRICT OF CALIFORNIA 6 SYNCHRONOSS TECHNOLOGIES, INC., 7 Plaintiff, 8 v. 9 DROPBOX INC., et al., 10 Defendants. 11 United States District Court Northern District of California Case No. 16-cv-00119-HSG ORDER GRANTING DROPBOX’S MOTION FOR SUMMARY JUDGMENT AND DENYING AS MOOT SYNCHRONOSS’S MOTION FOR SUMMARY JUDGMENT Re: Dkt. Nos. 275, 297, 306, 313, 315, 317, 322, 324, 326, 330, 333 12 13 Pending before the Court are cross-motions for summary judgment filed by Plaintiff 14 15 Synchronoss Technologies, Inc. (“Synchronoss”) and Defendant Dropbox, Inc. (“Dropbox”), 16 briefing for which is complete. Dkt. Nos. 317 (“Dropbox Mot.”), 333, 362, 368 (“Dropbox 17 Opp.”), 387 (“Dropbox Reply”), 389. The Court held a hearing on these motions on June 14, 18 2019. For the reasons discussed below, the Court GRANTS Dropbox’s motion for summary 19 judgment, and thus DENIES AS MOOT Synchronoss’s motion for summary judgment. 20 I. 21 22 BACKGROUND This case concerns two patents related to data synchronization: U.S. Patent Nos. 6,671,757 (“the ’757 Patent”) and 7,587,446 (“the ’446 Patent”) (collectively, “the Asserted Patents”). The ’757 Patent 23 A. 24 The ’757 Patent is titled “Data Transfer and Synchronization,” and claims a system and 25 method for “efficiently, quickly and easily synchronizing devices which can couple to the Internet, 26 or any network.” See ’757 Patent, 3:23–25. Synchronoss alleges that Dropbox directly infringes 27 claims 1, 8, 9, 14, 16, 21, 24, 26, and 28 of the ’757 Patent. See Dkt. No. 316-6 (“Alpaugh 28 Report”) ¶ 2(i). Independent claim 1 provides: 1 2 3 4 5 6 7 8 9 10 Claim 1 1. A system for synchronizing data between a first system and a second system, comprising: a first sync engine on the first system interfacing with data on the first system to provide difference information in a difference transaction; a data store coupled to the network and in communication with the first and second systems; and a second sync engine on the second system coupled to receive the difference information in the difference transaction from the data store via the network, and interfacing with data on the second system to update said data on the second system with said difference information; wherein each said sync engine comprises a data interface, a copy of a previous state of said data, and a difference transaction generator. The ’757 Patent’s two other independent claims, claims 16 and 24, include similar limitations as claim 1: United States District Court Northern District of California 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 Claim 16 16. A system, comprising: a first device including at least a first data file and first differencing code, the first device having an input and an output coupled to a network to receive first device data change transactions from, and provide change transactions generated by the first differencing code based on said at least one data file to, said network; a data store coupled to the network having at least one data structure coupled to store change transactions; and a second device including at least a second data file and second differencing code, the second device having an input and an output coupled to the network to receive said first device data change transactions from, and provide second change transactions generated by the second differencing code based on said at least second data file to, said data store; wherein said first differencing code includes a first sync engine having a first data interface, a first copy of a previous state of said data, and a first difference transaction generator, and said second differencing code includes a second sync engine having a second data interface, a second copy of a previous state of said data, and a second difference transaction generator. Claim 24 24. An Internet synchronization system, comprising: a storage server having an Internet connection; a first device coupled to the Internet and including a first device sync engine interfacing with data on the first device, the first device in communication with at least the storage server; and a second device coupled to the Internet and including a second device sync engine interfacing with data on the second device, the second device in communication with at least the storage server; 2 1 wherein each said device sync engine comprises a data interface, a copy of a previous state of said data, and a difference transaction generator. 2 3 4 two systems or devices by transmitting from one system to another certain “difference 5 information,” which the parties agree means “information that comprises only the changes to one 6 system’s data which have occurred on that system, and instructions for implementing those 7 changes.” See Dkt. No. 168 at 3. This difference information is transmitted through what is called 8 a “data store.” See, e.g., ’757 Patent, 3:43–45. 9 United States District Court Northern District of California In short, the ’757 Patent discloses a system and method for synchronizing data between B. The ’446 Patent 10 The ’446 Patent incorporates the ’757 Patent in its entirety, and is titled “Acquisition and 11 Synchronization of Digital Media to a Personal Information Space.” The invention “comprises a 12 method for acquiring and maintaining a digital music store in personal information space, 13 comprising: maintaining a personal information space identified with a user including data capable 14 of being used on a client device, and transferring at least a portion of the data from the personal 15 information space to an Internet-coupled device in response to a user request.” ’446 Patent, 3:45– 16 51. Synchronoss alleges that Dropbox directly infringes claims 1, 2, 6–15, 18 and 19 of the ’446 17 Patent. See Alpaugh Report ¶ 2(ii). Independent claim 1 provides: 18 Claim 1 19 1. A method of transferring media data to a network coupled apparatus, comprising: (a) maintaining a personal information space identified with a user including media data comprising a directory of digital media files, the personal information space being coupled to a server and a network; (b) generating a first version of the media data in the personal information space; (c) generating a digital media file, in response to an input from the user, comprising a second version of the media data in a same format as the first version in the personal information space, the second version including an update not included in the first version; (d) obtaining difference information comprising differences between the first version of the media data and the second version of the media data; and (e) transferring a digital media file over the network containing the difference information from the personal information space to the network coupled apparatus in response to a sync request made from a web browser at the network-coupled apparatus by the user. 20 21 22 23 24 25 26 27 28 3 1 Nine dependent claims add narrowing limitations such as (1) “including the step, prior to step (a), 2 of receiving information into the personal information space,” see ’446 Patent, Claim 2; and (2) 3 including a “directory of digital media files” to comprise the media data, see id., Claim 6. Additionally, claim 11 is independent, and provides: 4 5 Claim 11 11. A system for transferring digital media between a plurality of network coupled devices, comprising: a personal information store identified with a user containing digital media comprising a directory of digital media files readable by an application program; and a processing device, a server and a network coupled with the personal information store, the processing device including: an application data store holding a version of the digital media in the personal information store, and a device engine to: a) generate a digital media file, in response to an input from the user, comprising a second version of the media data in a same format as the first version in the personal information store, the second version including an update not included in the first version; (b) obtain difference information comprising differences between the first version of the media data and the second version of the media data; and (c) transfer a digital media file over the network containing the difference information from the personal information space to the network coupled apparatus in response to a sync request made from a web browser at the network-coupled apparatus by the user. 6 7 8 9 10 United States District Court Northern District of California 11 12 13 14 15 16 Claim 11 has three dependent claims. See id. at 14:58–64. 17 II. 18 LEGAL STANDARD A motion for summary judgment should be granted where there is no genuine issue of 19 material fact and the movant is entitled to judgment as a matter of law. Fed. R. Civ. P. 56; 20 Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 247–48 (1986). The purpose of summary 21 judgment “is to isolate and dispose of factually unsupported claims or defenses.” Celotex v. 22 Catrett, 477 U.S. 317, 323–24 (1986). The moving party has the initial burden of informing the 23 Court of the basis for the motion and identifying those portions of the pleadings, depositions, 24 answers to interrogatories, admissions, or affidavits which demonstrate the absence of a triable 25 issue of material fact. Id. at 323. 26 If the moving party meets its initial burden, the burden shifts to the non-moving party to 27 present facts showing a genuine issue of material fact for trial. Fed. R. Civ. P. 56; Celotex, 477 28 U.S. at 324. The Court must view the evidence in the light most favorable to the nonmovant, 4 1 drawing all reasonable inferences in its favor. T.W. Elec. Serv., Inc. v. Pac. Elec. Contractors 2 Ass'n, 809 F.2d 626, 630–31 (9th Cir. 1987). Summary judgment is not appropriate if the 3 nonmoving party presents evidence from which a reasonable jury could resolve the disputed issue 4 of material fact in the nonmovant’s favor. Anderson, 477 U.S. at 248. Nonetheless, “[w]here the 5 record taken as a whole could not lead a rational trier of fact to find for the non-moving party, 6 there is no genuine issue for trial.” Matsushita Elec. Indus. Co. v. Zenith Radio, 475 U.S. 574, 587 7 (1986) (internal quotation marks omitted). Infringement is a question of fact. Frank’s Casing Crew & Rental Tools, Inc. v. 8 United States District Court Northern District of California 9 Weatherford Int'l, Inc., 389 F.3d 1370, 1376 (Fed. Cir. 2004). The patent holder has the burden to 10 prove that each accused product “includes every limitation of [an asserted] claim.” Dolly, Inc. v. 11 Spalding & Evenflo Cos., 16 F.3d 394, 397 (Fed. Cir. 1994). The Court can resolve the issue on 12 summary judgment only if “no reasonable jury could find that every limitation recited in the 13 properly construed claim either is or is not found in the accused device.” Frank's Casing Crew, 14 389 F.3d at 1376 (internal quotation mark omitted); see also TechSearch, L.L.C. v. Intel Corp., 15 286 F.3d 1360, 1371 (Fed. Cir. 2002) (“[A]ll of the elements of the claim, as correctly construed, 16 must be present in the accused system.”). “Any deviation from the claim precludes” a finding of 17 literal infringement. Telemac Cellular Corp. v. Topp Telecom, Inc., 247 F.3d 1316, 1330 (Fed. 18 Cir. 2001). The absence from the accused product of one limitation in the claim means that, as a 19 matter of law, there is no literal infringement of that claim. Frank's Casing Crew, 389 F.3d at 20 1376. 21 III. 22 DROPBOX’S MOTION FOR SUMMARY JUDGMENT Dropbox moves for summary judgment on three grounds: (1) Dropbox does not directly 23 infringe the asserted patents; (2) the Dropbox system does not satisfy each limitation of the 24 asserted ’757 Patent claims; and (3) the asserted ’446 Patent claims are invalid and otherwise not 25 infringed. 26 A. 27 Turning first to whether there is direct infringement, which is a threshold issue, Dropbox 28 Direct Infringement argues that it is entitled to summary judgment on all asserted claims because Synchronoss has not 5 1 identified any evidence to establish that Dropbox has directly infringed either the ’757 or ’446 2 Patent. 3 United States District Court Northern District of California 4 1. Direct Infringement of the ’757 Patent As to the ’757 Patent, Synchronoss’s expert characterizes the infringement as relating to a 5 three-part system: a “first and second system,” which operate on “Dropbox desktop client” 6 machines, and a Dropbox central server. See, e.g., Alpaugh Report ¶¶ 96, 100, 105, 142, 148, 154, 7 182, 188, and 192. These systems correspond to the three common aspects of the asserted claims: 8 (1) a first “system” or “device” comprising specific software—specifically, a first “sync engine,” 9 “differencing code,” or “device sync engine,” depending on the claim at issue; (2) a second 10 “system” or “device” comprising similar software; and (3) a central “data store” or “storage 11 server” through which synchronization occurs. See ’757 Patent, 46:58–47:8, 48:1–24, 48:51–64. 12 Dropbox contends that it is entitled to summary judgment that it does not directly infringe 13 the asserted ’757 Patent claims because “there is no genuine dispute that Dropbox does not make, 14 use, sell, or offer to sell the accused system.” Dropbox Mot. at 8. In particular, Dropbox argues 15 that only its customers “use” the patented system for purposes of infringement, because only 16 Dropbox customers “put the invention into service, i.e., control the system as a whole and obtain 17 benefit from it.” Id. at 8–9 (quoting Centillion Data Sys., LLC v. Qwest Commc’ns Int’l, Inc., 631 18 F.3d 1279, 1284 (Fed. Cir. 2011)). Nor does Dropbox “make,” “sell,” or “offer to sell” the 19 accused system, according to Dropbox, for two reasons. Id. at 9–11. First, the required 20 configuration of two systems or devices in communication with a data store or storage server only 21 exists after the user downloads and installs the desktop client. Id. at 9. In other words, Dropbox 22 does not make, sell, or offer to sell an infringing “complete invention.” Id. at 8–9 (quoting Rotec 23 Indus., Inc. v. Mitsubishi Corp., 215 F.3d 1246, 1252 & n.2 (Fed. Cir. 2000)). Second, the 24 accused system requires both software and hardware, but Dropbox undisputedly does not make, 25 sell, or offer to sell any hardware. Id. at 10. 26 Synchronoss responds to Dropbox’s arguments in three ways. First, although Synchronoss 27 does not dispute that to directly infringe, Dropbox must make, sell, or offer to sell a “complete 28 invention,” Synchronoss nonetheless contends that Dropbox’s argument “misreads the claims and 6 1 rejects the Court’s claim construction.” Dropbox Opp. at 7. In particular, Dropbox relies on the 2 Court’s construction of the term “[first/second] system,” which is: 3 4 5 6 United States District Court Northern District of California 7 a collection of elements or components organized for a common purpose, and may include hardware components of a computer system, personal information devices, hand-held computers, notebooks, or any combination of hardware which may include a processor and memory which is adapted to receive or provide information to another device; or any software containing such information residing on a single collection of hardware or on different collections of hardware” 8 Id.; Dkt. No. 168 at 9–10. Synchronoss focuses exclusively on the language “or any software 9 containing such information residing on a single collection of hardware or on different collections 10 of hardware” to argue that Dropbox directly infringes the ’757 Patent by making, selling, and 11 offering for sale software that infringes once it is “in residence” on a user’s hardware. Dropbox 12 Opp. at 7–8. More to the point, Synchronoss claims that “[t]he participle phrase ‘residing on 13 hardware’ describes location; it is not an independent requirement of the claims.” Id. at 8. “In 14 other words,” Synchronoss contends, “the asserted claims are claiming the ‘software’ residing on 15 hardware, but not the hardware itself.” Id. 16 Contrary to Synchronoss’s position, the Court’s claim construction order unambiguously 17 held that “[first/second] system” did not cover software alone. See Dkt. No. 168 at 10 18 (“Defendants’ third argument concerning stand-alone software does not apply here, as the Court 19 understands the ’757 Patent’s use of the term ‘software’ to reference software in combination with 20 a hardware component or element.”). In fact, when discussing this claim term at the Markman 21 hearing, Synchronoss disclaimed any notion that the asserted claims need not encompass 22 “hardware,” as it now suggests: 23 26 [Counsel for Dropbox]: To the extent, Your Honor, that construction means -- again, we believe that Synchronoss has advanced the position in its briefing that that language seems to indicate just software. To the extent the construction is -- to the extent the code [sic] understands that language to be software in combination with hardware, we think that’s -- we think that’s appropriate as a construction. 27 The Court: And that’s what the specification says verbatim. 28 [Counsel for Synchronoss]: That's what our proposed construction 24 25 7 1 2 3 The Court: Right. So it sounds like no one’s arguing that a device could be software completely detached from hardware, correct? 4 [Counsel for Synchronoss]: That’s correct, Your Honor. 5 United States District Court Northern District of California actually says, "or any software containing such information residing on a single collection of hardware or on different collections of hardware," Your Honor. Dkt. No. 165 at 30:3–19. 6 At the hearing on the pending motions, Synchronoss’s principal argument in support of its 7 “in residence” theory of direct infringement was that the present claims are “exactly” like those in 8 Uniloc USA, Inc. v. Microsoft Corp., 632 F.3d 1292 (Fed. Cir. 2011). The Court disagrees. The 9 Uniloc court in fact rejected an argument similar to Synchronoss’s here, holding that the 10 defendant’s non-infringement argument based on the claims requiring both client-side and remote 11 components was “severely hampered by the language of” the claim, which “focuse[d] exclusively 12 on the ‘remote registration station.’” Id. at 1309. And liability for direct infringement could rest 13 with the defendant because “only one party, Microsoft, ma[de] or use[d] the remote registration 14 station.” Id. Unlike in Uniloc, the claimed systems here comprise both a storage server and two 15 client devices. See ’757 Patent at 46:58–47:8, 48:1–24, 48:51–64. And critical to the present 16 dispute, unlike Microsoft in Uniloc, Dropbox does not make nor use the entire claimed 17 combination of components. 18 Synchronoss next argues that notwithstanding the need for Dropbox users to complete the 19 invention, Dropbox may be liable for “divided infringement” under Akamai Technologies, Inc. v. 20 Limelight Networks, Inc., 797 F.3d 1020 (Fed. Cir. 2015). Dropbox Opp. at 9–10. Divided 21 infringement refers to a narrow situation where absent third parties are involved in practicing steps 22 in a claimed method, but where the third parties’ acts “are attributable to the [defendant] such that 23 [the defendant] is responsible for the infringement.” Akamai, 797 F.3d at 1022. Courts “will hold 24 an entity responsible for others’ performance of method steps in two sets of circumstances: (1) 25 where that entity directs or controls others’ performance, and (2) where the actors form a joint 26 enterprise.” Id. Whether a single entity “directs or controls the acts of another” turns on “general 27 principles of vicarious liability,” including whether the alleged infringer “acts through an agent 28 (applying traditional agency principles) or contracts with another to perform one or more steps of 8 1 a claimed method,” or where the “alleged infringer conditions participation in an activity or 2 receipt of a benefit upon performance of a step or steps of a patented method and establishes the 3 manner or timing of that performance.” Id. at 1022–23. The Court finds Synchronoss’s reliance on Akamai unavailing. Synchronoss does not United States District Court Northern District of California 4 5 allege that Dropbox forms a joint enterprise with its users. Nor has Synchronoss put forward any 6 evidence that Dropbox adequately directs or controls the user’s performance. For example, 7 Synchronoss does not contend that Dropbox conditions its users’ receipt of a benefit upon 8 performing certain actions that manifest infringement. Instead, Synchronoss merely relies on 9 Dropbox’s provision of instructions for using its software to demonstrate Dropbox’s control. 10 Dropbox Opp. at 9. But those facts, at most, might support a theory of induced infringement, a 11 theory of liability Synchronoss does not advance in this case. 12 As a final salvo, Synchronoss argues that summary judgment is at least unwarranted 13 because Dropbox has admitted to using the accused software on its own hardware. Dropbox Opp. 14 at 7. But the only factual support for this is a passing deposition statement that Dropbox 15 employees have stored PDFs on Dropbox. See Dkt. No. 367-12, at 40:23–41:10. No one argues, 16 however, that storage alone constitutes infringement of the ’757 Patent, and thus this statement 17 alone does not warrant denying Dropbox’s motion for summary judgment as to direct 18 infringement of the ’757 Patent. 19 Because there is no genuine dispute that Dropbox does not make, use, sell, or offer to sell a 20 complete infringing invention, the Court GRANTS Dropbox’s request for summary judgment that 21 it does not directly infringe the ’757 Patent.1 22 2. Direct Infringement of the ’446 Patent Dropbox next moves for summary judgment that it does not directly infringe the ’446 23 24 Patent. Dropbox Mot. at 11–12. The ’446 Patent contains both system and method claims. As to 25 the system claim (claim 11 and corresponding dependent claims), Dropbox argues that it does not 26 27 28 Because the Court grants Dropbox’s request for summary judgment that it does not directly infringe the ’757 Patent, the Court need not consider Dropbox’s alternative ground for summary judgment: that the Dropbox system does not satisfy each limitation of the asserted ’757 Patent claims. 9 1 United States District Court Northern District of California 1 directly infringe “for the same reason it does not directly infringe the claims of the ’757 Patent: 2 they recite a system that includes both hardware and software elements configured in a certain 3 way, and Dropbox neither sells nor configures the complete accused system.” Id. at 11. In 4 particular, claim 11 requires a “processing device.” And yet, Synchronoss only maintains that the 5 “processing device” limitation is satisfied in Dropbox’s accused system by a “computer . . . 6 together with the Dropbox desktop client.” See Alpaugh Report ¶ 262. As was true with the ’757 7 Patent, however, there is no dispute that Dropbox’s customers complete the system by supplying 8 their own computers. 9 Synchronoss’s only response concerning the system claims is to repeat its characterization 10 of the Court’s claim construction order and the phrase “any software containing such information 11 residing on a single collection of hardware or on different collections of hardware.” Dropbox 12 Opp. at 11 (“As discussed above, this limitation is met once the Dropbox software is in residence 13 on any hardware . . . and where the software resides has no impact on whether Dropbox 14 infringes.”). As discussed above, the Court finds this argument unavailing. 15 As to the ’446 Patent’s method claims (claim 1 and corresponding dependent claims), 16 Dropbox contends that under Akamai, direct infringement of a method claim only “occurs where 17 all steps of a claimed method are performed by or attributable to a single entity.” Dropbox Mot. at 18 12; 797 F.3d at 1022. Here, however, claim 1 includes a step of “generating a first version of the 19 media data,” which Dropbox contends that Synchronoss’s expert admits is performed by the 20 Dropbox user. Compare ’446 Patent, 13:53–54, with Alpaugh Report ¶ 222 (noting that this is 21 accomplished through “[u]ploading one or more photo or video files to Dropbox”). As 22 Synchronoss responds, however, Dropbox takes claim 1 out of context. Although it may be 23 necessary for a user to upload a photo or video before Dropbox’s software begins functioning, that 24 does not necessarily mean that the generation of a first version of the media data is performed by 25 the user. Instead, as Synchronoss’s expert states, the Dropbox software does the generation once 26 it receives the uploaded photo or video. Alpaugh Report ¶ 222. It is thus not undisputed that 27 Dropbox is entitled to summary judgment as to the asserted method claims of the ’446 Patent. 28 Because there is no genuine dispute that Dropbox does not make, use, sell, or offer to sell a 10 United States District Court Northern District of California 1 complete infringing invention, the Court GRANTS Dropbox’s request for summary judgment that 2 it does not directly infringe the ’446 Patent’s systems claims. But the Court DENIES Dropbox’s 3 request for summary judgment on this ground as to direct infringement of the ’446 Patent’s 4 method claims. Invalidity and Non-Infringement of the ’446 Patent 5 B. 6 Dropbox further argues that summary judgment is warranted in its favor as to all asserted 7 claims of the ’446 Patent because: (1) the claims are invalid as indefinite; and (2) Dropbox does 8 not infringe the claims for various reasons. For reasons that follow, the Court GRANTS 9 Dropbox’s request for summary judgment as to the ’446 Patent on the grounds that the relevant 10 claims are invalid as indefinite.2 The Court thus does not reach Dropbox’s alternative arguments 11 concerning non-infringement. As to definiteness, Dropbox contends that one particular impossibility permeates all of the 12 13 claims: the claims require “generating a [single] digital media file” that itself “compris[es] a 14 directory of digital media files.” Dropbox Mot. at 20–23. Claim 1 demonstrates this dispute, and 15 thus is worth repeating here: 16 Claim 1 17 1. A method of transferring media data to a network coupled apparatus, comprising: (a) maintaining a personal information space identified with a user including media data comprising a directory of digital media files, the personal information space being coupled to a server and a network; (b) generating a first version of the media data in the personal information space; (c) generating a digital media file, in response to an input from the user, comprising a second version of the media data in a same format as the first version in the personal information space, the second version including an update not included in the first version; (d) obtaining difference information comprising differences between the first version of the media data and the second version of the media data; and 18 19 20 21 22 23 24 25 26 27 28 Because the Court otherwise grants Dropbox’s request for summary judgment as to the ’446 Patent’s system claims, the Court here need only address the ’446 Patent’s method claims. The analysis that follows, however, applies equally to the system and method claims. Thus, even if Dropbox did not prevail on its direct infringement argument, summary judgment in Dropbox’s favor as to the system claims would be warranted on these independently sufficient grounds. 11 2 1 2 3 As written, (c) requires generating “a digital media file . . . comprising a second version of 4 the media data in the same format as the first version.” The “first version of the media data” 5 referenced in (b), however, relates back to (a), which is described as “comprising a directory of 6 digital media files.” Thus, according to Dropbox, the claims recite an impossibility, as a single 7 generated digital media file cannot itself comprise a directory of digital media files. Dropbox 8 Mot. 21. 9 United States District Court Northern District of California (e) transferring a digital media file over the network containing the difference information from the personal information space to the network coupled apparatus in response to a sync request made from a web browser at the network-coupled apparatus by the user. “[A] patent is invalid for indefiniteness if its claims [under Section 112, ¶ 2] read in light 10 of the specification delineating the patent, and the prosecution history, fail to inform, with 11 reasonable certainty, those skilled in the art about the scope of the invention.” Nautilus, Inc. v. 12 Biosig Instruments, Inc., 572 U.S. 898, 901 (2014). “Some modicum of uncertainty” is allowed, 13 but “a patent must be precise enough to afford clear notice of what is claimed, thereby appris[ing] 14 the public of what is still open to them.” Id. at 909 (internal quotation marks omitted). 15 “Otherwise there would be a zone of uncertainty which enterprise and experimentation may enter 16 only at the risk of infringement claims.” Id. (internal quotation marks and brackets omitted). 17 When asked about the apparent impossibility in claim 1, Synchronoss’s expert—Mr. 18 Alpaugh—conceded that “[a] digital media file cannot contain a directory of digital media files.” 19 See Dkt. No. 316-10 (“Alpaugh Tr.”) at 154:19–20. And Synchronoss’s 30(b)(6) designee echoed 20 that “if someone were to suggest that ‘media data’ always means ‘directory of digital media files’ 21 . . . then Clause C would not make sense. See Dkt. No. 316-12 at 175:15–176:5. Thus, rather than 22 defend the claim’s language, Synchronoss has sought to rewrite the claims. Mr. Alpaugh in 23 particular stated that “comprising was admittedly the wrong choice of words and perhaps the 24 better word here would have been resulting in a second version or some other choice.” Alpaugh 25 Tr. at 156:25–157:3 (emphasis added). 26 Dropbox contends that such claim redrafting to avoid invalidity under Section 112 27 contravenes well-settled Federal Circuit law. See Dropbox Mot. at 22–23 (citing Process Control 28 Corp. v. HydReclaim Corp., 190 F.3d 1350, 1357 (Fed. Cir. 1999), Allen Eng’g Corp. v. Bartell 12 1 Indus., Inc., 299 F.3d 1336, 1349 (Fed. Cir. 2002), and Trs. of Columbia Univ. v. Symantec Corp., 2 811 F.3d 1359 (Fed. Cir. 2016)). In response, Synchronoss argues that it and Mr. Alpaugh do not 3 suggest redrafting the claims, but rather that a person of ordinary skill in the art “would have 4 perceived the claims as drafted” to mean something different than what was written. Dropbox 5 Opp. at 21. But that is a distinction without a difference. To say that a person of ordinary skill 6 would understand that “red” means “blue,” is the same thing as rewriting “red” as “blue.” See 7 Allen Eng’g Corp., 299 F.3d at 1349 (“Allen argues that one of skill in the art would understand 8 that the term ‘perpendicular’ in the claim should be read to mean ‘parallel.’ Allen stretches the 9 law too far. It is not our function to rewrite claims to preserve their validity.”). Synchronoss further argues that summary judgment is inappropriate because claims “need United States District Court Northern District of California 10 11 not be perfectly clear to be deemed definite.” Dropbox Opp. at 19–20 (citing Nautilus, Inc., 572 12 U.S. at 910, Festo Corp. v. Shoketsu Kinzoku Kogyo Kabushiki Co., 535 U.S. 722, 731 (2002), 13 Minerals Separation v. Hyde, 242 U.S. 261, 270 (1916), and Invitrogen Corp. v. Biocrest Mfg., 14 L.P., 424 F.3d 1374, 1384 (Fed. Cir. 2005)). But Synchronoss misses the point, as there is a 15 difference between imprecise or ambiguous drafting and retrospective editing. And in this sense, 16 the Court finds this case is most similar to Allen Engineering Corp., where the Federal Circuit 17 rejected a patentee’s argument that “one of skill in the art would understand that the term 18 ‘perpendicular’ in the claim should be read to mean ‘parallel.’” 299 F.3d at 1349. The Federal 19 Circuit explained that “[i]t is not our function to rewrite claims to preserve their validity,” and “it 20 is of no moment that the contradiction is obvious.” Id. So too here. That Synchronoss admits that 21 the impossibility of its claim, as written, is apparent such that a person of ordinary skill in the art 22 would understand that it means something other than what is written does not render the claim 23 language definite; it does the opposite. For these reasons, the Court GRANTS Dropbox’s motion for summary judgment in its 24 25 favor as to all asserted claims of the ’446 Patent because the claims are invalid as indefinite under 26 Section 112. 27 // 28 // 13 United States District Court Northern District of California 1 IV. CONCLUSION 2 The Court GRANTS Dropbox’s motion for summary judgment as to all claims of 3 infringement on the grounds that (1) Synchronoss failed to show that Dropbox directly infringes 4 any claims of the ’757 Patent or the system claims of the ’446 Patent, and (2) the asserted claims 5 of the ’446 Patent are invalid as indefinite. 6 Because the Court grants Dropbox’s motion for summary judgment, the following motions 7 are DENIED AS MOOT: (1) Synchronoss’s motion for summary judgment, see Dkt. No. 333; (2) 8 the pending motions to strike portions of various expert reports, see Dkt. Nos. 275, 297, 306; and 9 (3) the pending Daubert motions, see Dkt. Nos. 313, 315, 322, 324, 326, 330. A separate order 10 will issue concerning the pending administrative motions to file under seal portions of the briefing 11 on these motions. The clerk is directed to enter judgment in favor of Defendant and to close the 12 file. 13 14 IT IS SO ORDERED. Dated: 6/17/2019 15 16 HAYWOOD S. GILLIAM, JR.
