`
`IV. THE PURPORTED INVENTION
`A. The Background of the ’671 Patent
`The ’671 patent has an earliest effective U.S. filing date of April 30, 2007,
`
`and refers to automobile systems operating on a Controller Area Network (CAN)
`
`bus.7
`
`

`6 Ex. 1005, Installation Manual For A Multimedia Interface 1280
`7 The ’671 patent is a continuation of application No. 14/846,811, which is a
`continuation of application No. 11/742,574, filed on April 30, 2007.
`
`3
`
`
`
`In 1985, Robert Bosch GmbH developed the Controller Area Network
`
`(CAN), which has emerged as the standard in-vehicle communication network.
`
`See generally Bosch. A CAN bus system provides a serial bus communication
`
`protocol used by Electronic Control Units (ECUs), also referred to as nodes. CAN
`
`protocols create a communication path linking all ECUs on the bus, enabling them
`
`to communicate with each other. The CAN bus system is a message-based system
`
`and all messages transmitted over the CAN bus are seen by all ECUs on that bus.
`
`See Johansson,8 8; Negley, 4-7.
`
`The ‘671 patent suggests that an aftermarket emergency call device was
`
`needed for vehicle owners who stopped paying subscription fees for “On Star”
`
`type services. See ’671 patent, 1:13-17, 4:56-5:20. However, the challenged
`
`claims are much broader.
`
`B. The Purported Solution
`Independent claim 6 calls for a vehicle having 1st factory-installed device,
`
`with a processor programmed to receive a 1st message having a message identifier
`
`from a 2nd factory-installed device over a vehicle data bus, a retrofit device with a
`
`processor connected to the vehicle data bus, and the retrofit device’s processor is
`
`programmed to transmit a 2nd message through a 2nd data bus that mimics the 1st
`
`
`8 Ex. 1011: Johansson, Vehicle Applications Of Controller Area Network,
`Handbook of Networked and Embedded Control Systems, 2005, pages 741-765.
`
`4
`
`
`
`message. Independent claim 10 claims a similarly-structured vehicle.
`
`Independent claim 1 claims a method of electrically disconnecting a vehicle
`
`data bus between two factory-installed apparatuses, and installing a retrofit device
`
`at the disconnection point to achieve a structure similar to that claimed in claims 6
`
`and 10.
`
`Dependent claims 16-18 (formerly dependent application claims 17-19,
`
`discussed below) include elements copied directly from Applicant’s Admitted
`
`Prior Art (“AAPA”), Lobaza.
`
`V.
`
`SUMMARY OF THE RELEVANT PROSECUTION HISTORY
`A copy of the ’67 patent’s file history, accessed from PAIR, is provided as
`
`Exhibit 1002. The ’671 patent as originally filed on April 9, 2017 included 19
`
`claims. Ex. 1002, 121-23.
`
`The May 23, 2017office action rejected claims 1-7, 9-13, and 17-19, and
`
`objected to claims 8 and 14-16. Application claims 17-19 claimed the second
`
`factory-installed apparatus as having, respectively, pre-impact limitations dealing
`
`with detecting objects in front of a vehicle, automatic braking and use of a parking
`
`aid system. These claims were rejected under 35 USC 112(a), first paragraph, for
`
`failing to comply with the written description requirement. Ex. 1002, 71.
`
`In a May 25, 2017 response, the applicant addressed the §112 rejection by
`
`copying, verbatim from Lobaza at 4:44-67, material dealing with a pre-impact
`
`5
`
`
`
`sensing system detecting objects in front of a vehicle, automatic braking, and aided
`
`parking. Ex. 1002, 58. The copied material was added to the specification at 7:28
`
`[“a pre-impact system 304”], and additional text at 7:34-58. The applicant also
`
`modified Figs. 3 and 4 by adding a “pre-impact system block 304.” Id. The
`
`applicant also argued that Kennedy did not show the claimed limitations, despite
`
`the clear fact that Lobaza did show those claimed features. Id., 59. These
`
`application claims 17-19 issued as claims 16-18, reciting features drawn from
`
`Lobaza.
`
`VI. CLAIM CONSTRUCTION
`The Board uses the same claim construction standard used by Article III
`
`federal courts, which is set forth in Phillips v. AWH Corp., 415 F.3d 1303 (Fed.
`
`Cir. 2005) (en banc) and its progeny, and includes “construing the claim in
`
`accordance with the ordinary and customary meaning of such claim as understood
`
`by one of ordinary skill in the art and the prosecution history pertaining to the
`
`patent.” See 37 C.F.R. § 42.100(b).
`
`A. Claim Construction
`The correct constructions of the ’671 patent terms are provided below.
`
`These constructions are consistent with the plain and ordinary meaning of the
`
`claims as would be understood by a person of ordinary skill in the art (“POSITA”)
`
`at the time of the invention, and the Phillips claim construction standard.
`
`6
`
`
`
`“data bus” (claims 1, 4, 6, 9-10, 13-15, 19)
`1.
`Independent claims 1, 6, and 10 each recite a “data bus,” and this term also
`
`appears in dependent claims 4, 9, 13-15, and 19. Construed in view of the
`
`specification and prosecution history, a POSITA would understand a “data bus” to
`
`refer to “a contiguous network providing a communication channel for two or
`
`more modules.” Leale, ¶59.
`
`The ’671 patent specification does not define a “data bus” but generally
`
`discloses a vehicle data bus as a network connecting a variety of apparatuses for
`
`electronic data communications. In one exemplary embodiment, the “data bus 212
`
`… may be a Class 2 or CAN vehicle data bus or any other suitable bus known in
`
`the art for electronic data communication.” ’671 patent, 7:30-33; see also Lobaza,
`
`4:40-43 (providing the same disclosure to describe “vehicle’s data bus 108”). The
`
`’671 patent also illustrates a vehicle “data bus” as a network for connecting
`
`apparatuses and providing a channel for data communications in various drawings,
`
`including FIGs. 2A, 2B, 2C, 3 and 4.
`
`Claim 9 of the ’671 patent also recites that the “vehicle data bus is a CAN
`
`network.” ’671 patent, 12:8-9. A POSITA at the time of the invention of the ’671
`
`patent would have understood the CAN acronym to stand for “Controller Area
`
`Network,” as developed by Robert Bosch GmbH. See generally Bosch. This is
`
`consistent with the use of the term, “CAN bus” in other references that pre-date the
`
`7
`
`
`
`’671 patent’s earliest filing date, including Munoz, who defines a “CAN-bus” as “a
`
`broadcast differential serial bus that has been incorporated as a standard interface
`
`on numerous automobile systems.” Munoz, 1:31-33.
`
`At the time of the ’671 patent’s date of invention, a POSITA would have
`
`understood that a “data bus” provides a channel between modules directly
`
`connected to the bus. Leale, ¶59. However, a discontinuity in the channel or
`
`network defines a limit of the data bus. This is also consistent with the ’671
`
`patent.
`
`FIG. 4 of the ’671 patent illustrates an embodiment of a vehicle
`
`communication system in which the “telecommunication apparatus 200 is in
`
`communication with vehicle data bus 212 using an indirect connection made
`
`t[h]rough emergency call apparatus [214], as will be explained in more detail with
`
`respect to FIG. 6 and FIG. 7.” ’671 patent, 7:59-64 (emphasis added).
`
`8
`
`
`
`Describing FIG. 7, the ’671 patent explains that the emergency call
`
`
`
`apparatus 214/710 includes two separate bus interfaces: one bus interface 700 to
`
`communicate with the electronic modules connected to vehicle data bus 212, and
`
`the other bus interface 504 to communicate with the telecommunication apparatus
`
`200 via a separate bus. Id., 8:60-67.

`
`
`
`
`These separate bus interfaces are “electrically insulated from each other,”
`
`and during normal operation, the emergency call apparatus 214/710’s control
`
`processor 500 acts “as a bidirectional gateway between” the separate bus
`
`interfaces. Id., 9:1-7. These disclosures confirm to a POSITA that the data bus
`
`connecting the telecommunications apparatus 200 and the emergency call
`
`apparatus 214/710 is not part of the vehicle data bus 212, but instead is a separate,
`
`or second, data bus, accessed via a separate bus interface 504. Ex. 1003, ¶¶100-05.
`
`Therefore, a POSITA would understand FIG. 4 and FIG. 7 as disclosing a vehicle
`
`data bus 212, and a separate, or second, data bus connecting the emergency call
`
`apparatus 214 and telecommunication apparatus 200. Id.
`
`2.
`
`“adding a second data bus” (claim 1) / “wherein the second
`data bus is added to the vehicle during a retrofit” (claim 19)
`Claims 1 and 19 each recite claim language directed to adding a second data
`
`bus. The “adding a second bus” step of claim 1 should be construed by the Board
`
`10
`
`
`
`as “adding a communication channel.” Leale, ¶59. The ’671 patent does not
`
`define the claimed term of “adding a second bus,” or comparable language.
`
`However, claim 1’s step of “adding a second bus,” and corresponding disclosure in
`
`the specification, neither requires nor precludes the installation of additional
`
`physical wiring serving as the second bus’s conductor. See ’671 patent, 9:47-
`
`10:15. Rather, the step of adding second data bus provides a communication
`
`channel between the 1st factory-installed apparatus (200) and the retrofit apparatus
`
`(214). Leale, ¶¶98-105.
`
`This interpretation is consistent with the specification’s discussion of adding
`
`a retrofit emergency call apparatus: “During the retrofit….. the electrical
`
`connection between the emergency call push button switch and the
`
`telecommunication apparatus is separated and the emergency call push button
`
`switch is rewired and connected to the emergency call apparatus.” ’671 patent,
`
`2:48-53, 6:65-7:24. The addition of the retrofit apparatus between two existing
`
`apparatuses includes rewiring of the existing electrical connections, but does not
`
`expressly require the installation of additional wiring.
`
`“responds” (claim 12)
`3.
`The word “responds” should be interpreted to mean “act on” which is
`
`consistent with the understanding of a POSITA in the field of CAN systems.
`
`Leale, ¶63; Negley, 6-7, 13, Figure 8.
`
`11
`
`
`
`The CAN system is a message-based system where every node listens to
`
`every message on the bus. Id., 6. A standard data frame of a CAN bus message
`
`includes a identifier field of 11 or 29 bits as a message identifier, and nodes use the
`
`identifier field to determine if a message should be acted on. Id., Figure 6, Figure
`
`8. To distinguish between messages on the bus the processor in an ECU will
`
`check the message identifier field against filter and mask registers to see if there is
`
`a match and to determine if an incoming message should be accepted and acted
`
`upon. Id., 9-12.
`
`VII. PERSON HAVING ORDINARY SKILL IN THE ART
`As explained in M.P.E.P. § 2141.03, a number of factors may be considered
`
`in determining the proper level of skill of a POSITA:
`
` (A) “type of problems encountered in the art;” (B) “prior art
`solutions to those problems;” (C) “rapidity with which
`innovations are made;” (D) “sophistication of the technology;
`and” (E) “educational level of active workers in the field.
`A POSITA at the time of the purported invention would have had a
`
`bachelor’s degree in engineering with relevant coursework, or at least two years of
`
`work experience in the design, operation, and functioning of CAN systems. Leale,
`
`¶51. Additional work experience could substitute for a bachelor’s degree, and
`
`additional education or training could substitute in part for work experience. Id.

`VIII. BRIEF DESCRIPTION OF THE PRIOR ART AND EVIDENCE OF
`CAN BUS STANDARDS
` “A reference will be considered publicly accessible if it was disseminated or
`
`otherwise made available to the extent that persons interested and ordinarily skilled
`
`in the subject matter or art exercising reasonable diligence, can locate it.” GoPro,
`
`Inc. v. Contour IP Holding LLC, 908 F.3d 690, 693 (Fed. Cir. 2018). As discussed
`
`below, each prior art reference relied upon was publicly accessible under this
`
`standard.
`
`A. U.S. Patent No. 7,737,831 (“Munoz”)
`Munoz was not of record during the prosecution of the ’671 patent. Munoz
`
`was filed on February 6, 2007, prior to the earliest effective filing date of the ’671
`
`patent, and is prior art against the ’671 patent under pre-AIA 35 U.S.C. § 102(e).
`
`B. U.S. Patent No. 6,812,832 (“Lobaza”)
`As already introduced in Section V above, Lobaza is Applicant Admitted
`
`Prior Art (see ’671 patent, 1:36-38), and material from Lobaza was copied into the
`
`’671 patent specification during prosecution. Lobaza issued on Nov. 2, 2004.
`
`C. Installation Manual For A Multimedia Interface 1280 (“Dietz”)
`Audiotechnik Dietz Vertrieba GmbH, Benzstrasse 12 D-67269 Gruntadt,
`
`sold a retrofit 1280 multimedia interface for playing TV in a moving vehicle and
`
`provided to its customers a six-page installation guide (in German and English)
`
`13
`
`
`
`dated “30.11.04” (November 30, 2004). This guide (“Dietz”) is submitted as Ex.
`
`1005. Neither Dietz nor the 1280 Multimedia Interface was of record during the
`
`prosecution of the ’671 patent, and Dietz’s publication date of November 30, 2004
`
`is more than one year prior to the earliest effective filing date of the ’671 patent.
`
`Dietz was publicly accessible at least as early as October 21, 2005. Leale, ¶¶28-
`
`30. Dietz is prior art under pre-AIA 35 U.S.C. §§ 102(a) and (b).9
`
`D. Robert Bosch GbmH, “CAN Specification, Version 2.0” (“Bosch”)
`This 1991 Bosch CAN Specification, referenced as CAN 2.0A, used or
`
`supported an 11-bit or standard identifier. In 1995, Bosch modified the protocol
`
`and introduced CAN 2.0B that supported an extended 29-bit identifier. The CAN
`
`protocol was internationally standardized in 1993 as ISO 11898-1. See Johansson,
`
`10. Bosch was publicly accessible at least as early as December 2005, more than
`
`one year prior to the earliest effective filing date of the ’671 patent. Leale, ¶¶35-
`
`36. Bosch is prior art under pre-AIA 35 U.S.C. §§ 102(a) and (b).
`
`E. “Getting Control Through CAN,” Sensors, October 2000, Vol. 17,
`#10 (“Negley”)
`Negley was not of record during the prosecution of the ’671 patent. Negley
`
`9 Ex. 1012 is an Invoice dated October 21, 2005 to Perzan Auto Radio, Inc., 6409
`
`Market Street, Upper Darby PA 19082 for an Order No. 101505, that included a
`
`U.S. sale of Dietz’s Multimedia Interface 1280.
`
`14
`
`
`
`was published in October 2000 in a Sensors publication more than one year prior
`
`to the earliest effective filing date of the ’671 patent. Leale, ¶¶31-33. Negley is
`
`prior art under pre-AIA 35 U.S.C. §§ 102(a) and (b).
`
`F. SAE Technical Paper Series, 930005, “A Gateway For CAN
`Specification 2.0 Non-Passive Devices,” by Szydlowski (“SAE”)
`SAE was not of record during the prosecution of the ’671 patent. SAE was
`
`published in 1993, more than one year prior to the earliest effective filing date of
`
`the ’671 patent, and was publicly accessible at least as early as 1993. Leale, ¶34.
`
`SAE is prior art under pre-AIA 35 U.S.C. §§ 102(a) and (b).
`
`G. Background on Controlled Area Networks (CAN) Systems
`The ’671 patent and the prior art all function using “Controlled Area
`
`Networks” or CAN communication systems. A POSITA would understand the
`
`operation of CAN systems according to the protocols disclosed in Bosch, Negley,
`
`and SAE. These references provide evidence of the state of knowledge in the art
`
`as of the ’671 patent’s earliest effective filing date. Leale, ¶43.
`
`A POSITA would have understood that CAN systems employ well-known
`
`protocols in a message-based system using four types of frames that have a unique
`
`and fixed structure, including data frames that are used to broadcast data from a
`
`transmitter to the other nodes on a CAN bus and include an identifier field using
`
`identifier bits as a message identifier. See Bosch, 12-13, 45-47; Leale, ¶55.
`
`15
`
`
`
`ECUs connected to a CAN bus have a processor that converts received data
`
`from a CAN bus level to a level the CAN controller uses, and converts transmitted
`
`data from the CAN controller level to the CAN bus level. Leale, ¶¶40-43; Negley,
`
`4-7.
`
`ECUs on the CAN bus receive all messages transmitted over the CAN bus
`
`and examine the identifier field so that the identifier bits can be compared against
`
`the ECU’s filters and masks to see if ther
