Stragent, LLC v. BMW of North America, LLC, et al Doc. 108 Case 1:20-cv-00510-JDW Document 108 Filed 08/09/22 Page 1 of 16 PageID #: 8382 IN THE UNITED STATES DISTRICT COURT FOR THE DISTRICT OF DELAWARE STRAGENT, LLC, Case No. 1:20-cv-00510-JDW Plaintiff, v. BMW OF NORTH AMERICA, LLC, et al., Defendants. STRAGENT, LLC, Plaintiff, Case No. 1:20-cv-00511-JDW v. MERCEDES-BENZ USA, LLC, et al., Defendants. STRAGENT, LLC, Plaintiff, Case No. 1:22-cv-00293-JDW v. VOLVO CAR USA, LLC, Defendant. MEMORANDUM In this series of related lawsuits, Stragent, LLC alleges that various car manufacturers, including Defendants BMW of North America, LLC, BMW Manufacturing Co., LLC, Mercedes-Benz USA, LLC, and Volvo Car USA, LLC, infringe four of Stragent’s Dockets.Justia.com Case 1:20-cv-00510-JDW Document 108 Filed 08/09/22 Page 2 of 16 PageID #: 8383 patents. Those patents relate to automotive electronic control units’ sharing of information between different networks that might use different protocols. Stragent contends that the Defendants’ manufacture, use, sale, and/or offer for sale of vehicles that contain Automotive Open System Architecture technology infringes those patents. The Parties have submitted to the Court for construction six terms from the four patents in suit, Patent Nos. 9,705,765 (the “‘765 Patent”), 10,002,036 (the “‘036 Patent”), 10,031,790 (the “‘790 Patent”), and 10,248,477 (the “‘477 Patent”). The Court held a hearing on June 29, 2022, and now resolves the disputed constructions. I. LEGAL STANDARD “It is a ‘bedrock principle’ of patent law that ‘the claims of a patent define the invention to which the patentee is entitled the right to exclude.’” Phillips v. AWS Corp., 415 F.3d 1303, 1312 (Fed. Cir. 2005) (quotation omitted). Claim construction is a matter of law. See Teva Pharm. USA, Inc. v. Sandoz, Inc., 135 S. Ct. 831, 837 (2015). “[T]here is no ‘magic formula or catechism’” for construing a patent claim, nor is a court “barred from considering any particular sources or required to analyze sources in any specific sequence[.]” Phillips, 415 F.3d at 1324. Instead, a court is free to attach the appropriate weight to appropriate sources “in light of the statutes and policies that inform patent law.” Id. (citation omitted). A court generally gives the words of a claim “their ordinary and customary meaning”, which is the “meaning that the term would have to a person of ordinary skill in 2 Case 1:20-cv-00510-JDW Document 108 Filed 08/09/22 Page 3 of 16 PageID #: 8384 the art at the time of the invention, i.e., as of the effective filing date of the patent application.” Id. at 1312-13 (quotations omitted). Usually, a court first considers the claim language; then the remaining intrinsic evidence; and finally, the extrinsic evidence in limited circumstances. See Interactive Gift Exp., Inc. v. Compuserve, Inc., 256 F.3d 1323, 1331-32 (Fed. Cir. 2001). While “the claims themselves provide substantial guidance as to the meaning of particular claim terms[,]” a court also must consider the context of the surrounding words. Phillips, 415 F.3d at 1314. In addition, the patent specification “‘is always highly relevant to the claim construction analysis’ and indeed is often ‘the single best guide to the meaning of a disputed term.’” AstraZeneca AB v. Mylan Pharms. Inc., 19 F.4th 1325, 1330 (Fed. Cir. 2021) (quotation omitted). But, while a court must construe claims to be consistent with the specification, the court must “avoid the danger of reading limitations from the specification into the claim ….” Phillips, 415 F.3d at 1323. This is a “fine” distinction. Comark Communications, Inc. v. Harris Corp., 156 F.3d 1182, 1186–87 (Fed.Cir.1998). In addition, “[e]ven when the specification describes only a single embodiment, the claims of the patent will not be read restrictively unless the patentee has demonstrated a clear intention to limit the claim scope using ‘words or expressions of manifest exclusion or restriction.’” Hill-Rom Svcs., Inc. v. Stryker Corp., 755 F.3d 1367, 1372 (Fed. Cir. 2014) (quotation omitted) (alterations in original). A court may refer to extrinsic evidence only if the disputed term’s ordinary and accustomed meaning cannot be discerned from the intrinsic evidence. See Vitronics Corp. 3 Case 1:20-cv-00510-JDW Document 108 Filed 08/09/22 Page 4 of 16 PageID #: 8385 v. Conceptronic, Inc., 90 F.3d 1576, 1584 (Fed. Cir. 1996). Although a court may not use extrinsic evidence to vary or contradict the claim language, extrinsic materials “may be helpful to explain scientific principles, the meaning of technical terms, and terms of art that appear in the patent and prosecution history.” Markman v. Westview Instruments, Inc., 52 F.3d 967, 980 (Fed. Cir. 1995). Extrinsic evidence is used “to ensure that the court’s understanding of the technical aspects of the patent is consistent with that of a person of skill in the art[.]” Phillips, 415 F.3d at 1318. The Federal Circuit has cautioned against relying upon expert reports and testimony that is generated for the purpose of litigation because of the likelihood of bias. Id.; see also Daubert v. Merrell Dow Pharms., Inc., 509 U.S. 579, 595 (1993) (“Expert evidence can be both powerful and quite misleading because of the difficulty in evaluating it.”) (quotation omitted). Ultimately, “[t]he construction that stays true to the claim language and most naturally aligns with the patent’s description of the invention will be . . . the correct construction.” Renishaw PLC v. Marposs Societa’ per Anzioni, 158 F.3d 1243, 1250 (Fed. Cir. 1998). It follows that “a claim interpretation that would exclude the inventor’s device is rarely the correct interpretation[.]” Modine Mfg. Co. v. U.S. Int'l Trade Comm'n, 75 F.3d 1545, 1550 (Fed. Cir. 1996), abrogated on other grounds by, Festo Corp. v. Shoketsu Kinzoku Kogyo Kabushiki Co., 234 F.3d 558 (Fed. Cir. 2000), vacated, 535 U.S. 722 (2002). 4 Case 1:20-cv-00510-JDW Document 108 Filed 08/09/22 Page 5 of 16 PageID #: 8386 Case 1:20-cv-00510-JDW Document 108 Filed 08/09/22 Page 6 of 16 PageID #: 8387 that that mode ”allows inspection of the system while it is running rather than what it does.” (D.I. 63, 100.) The construction of “debugging mode” should parallel the agreed construction of “diagnostic mode” by defining what the mode “allows.” The Court can assume that when the inventors described two modes, juxtaposed together in the claim language, they had similar intent. In addition, having consistent constructions of different modes will aid the jury in understanding the claims. So the Court’s construction defines what the distinct mode allows based on the language of the specification. The Court rejects Stragent’s alternative proposed approach for several reasons. First, it focuses on the definition of “debugging,” rather than “debugging mode.” Although Stragent complains that the Defendants’’ proposed construction does not define what “debugging” is, Stragent did not ask the Court to construe the word “debugging;” it joined in a request to construe “debugging mode.” Notably, Stragent agreed to a construction of “diagnostic mode” without seeking to define “diagnostic” or “diagnose.” That agreement demonstrates that the construction of a “mode” does not necessarily require the construction of the descriptive word in the name of the mode. Stragent’s focus on the word “debugging,” rather than “debugging mode,” means that its arguments miss the mark. Second, Stragent’s proposed construction relies almost entirely on extrinsic evidence—a technical definition of “debugging.” But Stragent has not shown a need to resort to extrinsic evidence, particularly when the specification speaks to the construction. 6 Case 1:20-cv-00510-JDW Document 108 Filed 08/09/22 Page 7 of 16 PageID #: 8388 Contrary to Stragent’s arguments, reading the claim term in view of the specification is not the same as limiting the claim to the described embodiment. Finally, in light of the Parties’ agreed-upon construction of “diagnostic mode,” Defendants’ proposed construction of “debugging mode” makes clear that the two modes are not the same. In fact, the mirroring constructions will make it easier for the jury to understand that while diagnostic mode permits inspection of the system while it is running, debugging mode permits the same inspection but is different because it can also allow the network to run in a fail-safe reduced operation mode. That is, it can do something that diagnostic mode does not do. As a result, this construction does not run afoul of the presumption that “the use of these ‘two terms in a claim requires that they connote different meanings.’” Neville v. Found. Constructors, Inc., 972 F.3d 1350, 1357 (Fed. Cir. 2020) (quotation omitted). The Court agrees that both a POSITA and the jury will understand what is meant by a fail-safe reduced operation mode and, therefore, adopts Defendants’ proposed construction. 7 Case 1:20-cv-00510-JDW Document 108 Filed 08/09/22 Page 8 of 16 PageID #: 8389 Case 1:20-cv-00510-JDW Document 108 Filed 08/09/22 Page 9 of 16 PageID #: 8390 Case 1:20-cv-00510-JDW Document 108 Filed 08/09/22 Page 10 of 16 PageID #: 8391 Case 1:20-cv-00510-JDW Document 108 Filed 08/09/22 Page 11 of 16 PageID #: 8392 Case 1:20-cv-00510-JDW Document 108 Filed 08/09/22 Page 12 of 16 PageID #: 8393 require storing the information before sharing it. Second, neither the specifications nor the accompanying figures require that information be stored before it can be shared. Third, though not binding on this Court, the PTAB concluded that the same term in parent patent(s) did not require that the information be stored. Because neither the claim language nor the intrinsic evidence explains what it means to “share” the information, the Court may rely on extrinsic evidence for guidance. See Vitronics, 90 F.3d at 1584 n.6. Stragent points to the technical definition of “share,” which means “[t]o make files, directories, or folders accessible to other users over a network.” Microsoft Computer Dictionary, 477 (5th Ed. 2002); see also Newton’s Telecom Dictionary, 1133 (30th Ed. 2016) (defining “share” as “[t]o make resources … available to network users”). This definition is consistent with the Parties’ respective proposals that sharing refers to “permitting the information … to be used by another process” and “making the information accessible.” However, the Court adopts Defendants’ proposed construction because it is the simpler of the two and is more consistent with the technical definition of “sharing.” The Court will not adopt the remaining portion of Defendants’ proposed construction: “without requiring storage of the information.” The “explicit claim language” does not support this negative limitation. Omega Eng’g, Inc, v. Raytek Corp., 334 F.3d 1314, 1322 (Fed. Cir. 2003). Nor have Defendants “identified any express disclaimer or independent lexicography in the written description that would justify adding that 12 Case 1:20-cv-00510-JDW Document 108 Filed 08/09/22 Page 13 of 16 PageID #: 8394 negative limitation.” Id. at 1323. Because none of the accepted bases for importing a negative limitation is present here, the Court will not adopt this portion of Defendants’ proposal. Likewise, the Court will not adopt Stragent’s proposed construction because it rests on a misunderstanding of the term “the information.” Although the claims are not identical, claim 1 in the ‘790 Patent provides a representative sample of the claim language at issue. The first reference to “information” in that claim is “information associated with a message received ….” (‘790 Patent, 12:44-45.) Subsequent references to “the information” in the claim refer back to that first reference. Stragent contends that the information must have been “stored” (D.I. 66 at 15), but the claim language does not impose that requirement. To the contrary, the claim discusses the possibility that the apparatus will not store the information “in the event the storage resource is not available.” (E.g., ‘790 Patent 12:65.) Most importantly, the sharing of information occurs pursuant to claim limits separate from the limits that discuss accessing storage resources, so in theory one could satisfy limits concerning sharing without first requiring storage. Thus, Stragent’s proposed construction that the information being shared must first have been stored, is at odds with the plain language of the patent. 13 Case 1:20-cv-00510-JDW Document 108 Filed 08/09/22 Page 14 of 16 PageID #: 8395 Case 1:20-cv-00510-JDW Document 108 Filed 08/09/22 Page 15 of 16 PageID #: 8396 these definitions, the Court will construe the disputed term as: “choose options for organizing data in the nonvolatile memory.” Defendants’ proposal rests on an assumption that the configuration described in the disputed claim term occurs in “configuration mode,” but they do not point to anything in the intrinsic evidence to support that assumption. Even if Defendants are correct that any configuration of the data structure occurs in configuration mode, they do not offer any explanation why the Court should construe the term to refer to making a change, as opposed to making an update. The specification discloses updating as an action that can happen in configuration mode. (See ‘477 Patent, 10:9-12, 11:28-33.) Despite this, Defendants argue that “configure” must mean “change.” Finally, Defendants do not propose any construction for “data structure.” Stragent’s reliance on intrinsic evidence also falls short. The specification on which Stragent relies describes a bulletin board embodiment and discloses that “[t]he bulletin board manager (501) contains an upgrade and configuration manager (507)” that “is necessary to configure the data structure of the bulletin board ….” (‘477 Patent, 4:39-44.) This specification sheds no light on what “configure” or “data structure” means. Instead, it tracks the language of the claim itself, which is not helpful. Beyond that, Stragent bases its argument on extrinsic evidence, but its proposed construction has no connection to the extrinsic evidence that it cites. In short, Stragent gives the Court no reason to adopt its construction. 15 Case 1:20-cv-00510-JDW Document 108 Filed 08/09/22 Page 16 of 16 PageID #: 8397 III. CONCLUSION The Court will construe the disputed claims as described above, and it will adopt the Parties’ agreed-upon constructions. An appropriate Order follows. BY THE COURT: /s/ Joshua D.
