Opinion

1 2 3 4 5 6 7 UNITED STATES DISTRICT COURT 8 NORTHERN DISTRICT OF CALIFORNIA 9 ARSUS, LLC, 10 Case No. 20-cv-00313-RS Plaintiff, 11 v. CLAIMS CONSTRUCTION ORDER 12 TESLA MOTORS, INC., 13 Defendant. 14

15 16 INTRODUCTION 17 In the operative Second Amended Complaint, plaintiff Arsus, LLC alleges defendant Tesla 18 Motors, Inc.’s “Autopilot” system offered in Tesla automobiles infringes United States Patent No. 19 8,634,989 (“the ’989 Patent”) and United States Patent No. 10,259,494 (“the ’494 Patent”), both 20 of which are entitled “Rollover Prevention Apparatus.” The parties now seek construction of the 21 claims of the ’989 patent.1 The heart of the dispute is whether the patent claims an apparatus that 22 physically prevents a human driver from steering a vehicle to the point where it will rollover, or 23 whether an autopilot system that will not steer to the point of rollover can infringe, even if a 24 human driver can disengage the autopilot merely by turning the steering wheel to resume human 25 control—and thereby potentially steer the vehicle beyond the point of rollover. 26

27 1 The record is unclear as to whether Arsus is still pursuing its claims under the ’494 Patent or 1 Tesla argues the claims should be treated as “means-plus-function” claims under 2 35 U.S.C. 112(f) (previously 35 U.S.C. 112, sixth paragraph).2 Alternatively, Tesla proposes 3 constructions of the claim language that would explicitly include language referring to the 4 presence of a human driver and/or exclude autonomous driving systems. Arsus, in turn, insists 5 none of the claims refer to a human driver or should be construed to include a limitation that 6 excludes autonomous systems. 7 While the claims lack the familiar “means for” language invoking 35 U.S.C. 112(f), they 8 only describe the claimed “apparatus” in terms of its functions, and do not recite structure that 9 performs those functions. Accordingly, the claims must be construed as reaching only the structure 10 described in the specification that correspond to those claimed functions, and any equivalents 11 thereto. Otherwise, the claims would extend to any and every system that performs the function of 12 preventing vehicle rollover. Arsus cannot reasonably claim it has a patent on the basic idea of 13 preventing rollover, without regard to how a particular system attempts to achieve that result. 14 15 BACKGROUND 16 The specification of the ’989 patent asserts “[v]ehicle rollover—generally defined as 17 vehicular accident in which a vehicle turns over on its side or roof—is an extremely dangerous 18 form of a vehicle crash.”

19 While there may be several factors for a vehicle to be turned or steered beyond the vehicle threshold of roll such as driver hurry or 20 impatience and driver inexperience, a well know[n] cause for excessive turning or steering to the point of vehicle roll is the 21 occurrence of an object such as a tumble weed or squirrel suddenly appearing in the driver[’]s path (hereafter referred to Sudden Object 22 Appearance or SOA). In such SOA, even the most experienced drivers can feel the inherent and immediate urge to rapidly turn the 23 steering wheel. It is just such turning of the steering wheel that causes many vehicle rollovers. 24

25 2 Tesla also asserts the claims are improper under that section because they are “single means 26 claims,” rather than claims “for a combination” as permitted under the statute. This order’s conclusion that the claims can only be interpreted through the “means-plus-function” lens does not 27 reach the separate issue as to whether they might be invalid as “single means claims.” 1 ’989 Patent, 1:35-45. 2 This and other passages in the specification clearly imply the claimed invention 3 contemplates an apparatus that physically prevents a driver from steering the vehicle to the point 4 of rollover. As Arsus points out, however, the claim language includes no express reference to a 5 driver. The order denying Tesla’s motion to dismiss the operative complaint concluded:

6 Arsus’s argument that the Tesla system infringes because it prevents the autopilot from oversteering is not so inconsistent with the 7 language of the claims on their face as to permit resolution at the pleading stage. 8 9 Claims construction, of course, does not address infringement. Additionally, this order 10 does not find the claims should be construed expressly to require a human driver. Instead, as 11 noted, the claims will be found to be governed by section 112(f) (or, more precisely, the sixth 12 paragraph of section 112 as in effect when the patent issued) and therefore limited to the 13 corresponding structure in the specification, and any equivalents thereof. 14 15 LEGAL STANDARD 16 Claim construction is a question of law to be determined by the courts. See Markman v. 17 Westview Instruments, Inc., 52 F.3d 967, 979 (Fed. Cir. 1995). “Ultimately, the interpretation to be 18 given a term can only be determined and confirmed with a full understanding of what the 19 inventors actually invented and intended to envelop with the claim.” Phillips v. AWH Corp., 415 20 F.3d 1303, 1316 (Fed. Cir. 2005) (quoting Renishaw PLC v. Marposs Societa’ per Azioni, 158 21 F.3d 1243, 1250 (Fed. Cir. 1998)). Accordingly, a claim should be construed in a manner “most 22 naturally align[ed] with the patent’s description of the invention.” Id. 23 The first step in claim construction is to look to the language of the claims themselves. “It 24 is a ‘bedrock principle’ of patent law that ‘the claims of a patent define the invention to which the 25 patentee is entitled the right to exclude.’” Phillips, 415 F.3d at 1312 (quoting Innova/Pure Water, 26 Inc. v. Safari Water Filtration Sys., Inc., 381 F.3d 1111, 1115 (Fed. Cir. 2004)). A disputed claim 27 term should be construed in a manner consistent with its “ordinary and customary meaning,” 1 which is “the meaning that the term would have to a person of ordinary skill in the art in question 2 at the time of the invention, i.e., as of the effective filing date of the patent application.” Id. at 3 1312–13. The ordinary and customary meaning of a claim term may be determined solely by 4 viewing the term within the context of the claim’s overall language. See id. at 1314 (“[T]he use of 5 a term within the claim provides a firm basis for construing the term.”). Additionally, the use of 6 the term in other claims may provide guidance regarding its proper construction. See id. (“Other 7 claims of the patent in question, both asserted and unasserted, can also be valuable sources of 8 enlightenment as to the meaning of a claim term.”). 9 A claim should also be construed in a manner consistent with the patent’s specification. 10 See Markman, 52 F.3d at 979 (“Claims must be read in view of the specification, of which they 11 are a part.”). Typically, the specification is the best guide for construing the claims. See Phillips, 12 415 F.3d at 1315 (“The specification is . . . the primary basis for construing the claims.”); 13 Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1582 (Fed. Cir. 1996) (“[T]he specification is 14 always highly relevant to the claim construction analysis. Usually, it is dispositive; it is the single 15 best guide to the meaning of a disputed term.”).
