`INTRODUCTION
`
`
`
`Patent Owner American Vehicular Sciences LLC (“AVS”) submits the
`
`following Motion to Amend under 37 C.F.R. § 42.121 in connection with the
`
`above-captioned inter partes review of U.S. Patent No. 8,036,788 (“the 788
`
`patent”). AVS respectfully submits that its Motion satisfies AVS’s burden of proof
`
`that its proposed substitute claims are patentable and supported by written
`
`description.
`
`II. LISTING OF SUBSTITUTE CLAIMS
`AVS seeks to cancel claims 1, 3, 4, 6, 7, 8, 11, 15, 16 and 18 of the 788
`
`patent.1 Proposed substitute claims 22 through 31 are set forth below, with
`
`additions to the language of the corresponding issued claim indicated by
`
`underlining and any deletions indicated by bracketing. Substitute claims 22 and 24
`
`are independent claims to which additional limitations have been added. The
`
`remaining substitute claims are dependent claims that are only being amended to
`
`reflect the change in dependency.
`
`
`1 For clarity, AVS notes that it is simultaneously filing a Patent Owner’s Response
`
`in this inter partes review. AVS’s Patent Owner’s Response requests that the
`
`patentability of claim 9 be confirmed. AVS is not seeking to cancel claim 9 and
`
`AVS has not proposed a substitute claim for claim 9.

`Patent Owner’s Motion To Amend
`IPR2013-00417
`III. CLAIM CONSTRUCTION
`For purposes of this Motion to Amend only, AVS does not contest the
`
`
`
`Board’s construction of claim terms in the originally-issued claims. (Paper 14 at 8-
`
`12.) In particular, AVS does not contest the Board’s construction of, and/or
`
`commentary regarding, the terms: “component”; “sensor”; “triggering event”; and
`
`“diagnostic or prognostic message.”
`
`Claim 22 adds the following limitations: “during operation of the vehicle on
`
`a road” and “wherein the diagnostic or prognostic message includes an
`
`identification of the at least one component or subsystem and an identification of
`
`whether the at least one component or subsystem should be either repaired or
`
`replaced.” Many of the words appearing in the added language were present in the
`
`original claim language and/or have already been construed by the Board, e.g.,
`
`“component” and “diagnostic or prognostic message.” Of the remaining words,
`
`AVS believes that these words are ordinary words whose meaning can be readily
`
`understood. Nevertheless, for the sake of clarity and out of an abundance of
`
`caution, AVS offers the following proposed constructions of the words “repaired”
`
`and “replaced.”
`
`The specification assigns no special meaning to the word “repaired.” The
`
`ordinary meaning of the word “repair,” as supported by its dictionary definition, is
`
`“to restore to a sound or healthy state.” (Ex. 2006; Ex. 2002 at ¶ 47.) As AVS’s
`
`
`
`5
`
`
`
`Patent Owner’s Motion To Amend
`IPR2013-00417
`
`expert, Mr. Kennedy explains, in the context of these claims, e.g., vehicles
`
`operating on a road, one of ordinary skill in the art would understand the word
`
`“repair” or “repaired” to mean “to restore the identified component to meet
`
`original specified design requirements.” (Ex. 2002 at ¶ 47.)
`
`The specification likewise assigns no special meaning to the word
`
`“replaced.” The ordinary meaning of “replace,” as supported by its dictionary
`
`definition, is “to put something new in place of.” (Ex. 2006; Ex. 2002 at ¶ 47.)
`
`AVS’s expert explains that in the context of these claims, e.g., vehicles operating
`
`on a road, one of ordinary skill in the art would understand the word “replace” or
`
`“replaced” to mean “to put something different in place of the identified
`
`component that meets the original specified design requirements.” (Ex. 2002 at ¶
`
`47.) In the context of these claims “replace” or “replaced” would not be limited to
`
`“new” elements because often times in the automotive industry, broken vehicular
`
`elements are replaced not with “new” elements, but with refurbished ones. (Id.)
`
`Claim 24 adds the following limitations: “during operation of the vehicle on
`
`a road” and “wherein the diagnostic or prognostic message includes an
`
`identification of the at least one of the plurality of different components or
`
`subsystems of the vehicle and an identification of whether the at least one of the
`
`plurality of different components or subsystems of the vehicle should be either
`
`repaired or replaced.” These claim limitations are substantially similar to the claim
`
`
`
`6
`
`
`
`Patent Owner’s Motion To Amend
`IPR2013-00417
`
`limitations added to claim 22. The constructions set forth above with respect to
`
`claim 22 apply to claim 24.
`
`IV. SUPPORT FOR THE PROPOSED CLAIMS
`Support for claim 22 can be found in the original-filed application that led to
`
`the 788 patent (Ex. 1007). For example, the application repeatedly describes and
`
`depicts diagnostic monitoring occurring while the vehicle is operating on the road.
`
`(See, e.g., Ex. 1007 at Figs. 3, 5-6; p. 11, 24, 28, 812; Ex. 2002 at ¶ 49.) Moreover,
`
`the application describes diagnostic or prognostic messages that contain an
`
`identification of the component or subsystem and an identification of whether the
`
`component or subsystem needs to be repaired or needs to be replaced. (Ex. 1007 at
`
`16-17, 19, 22, 28-31, 72, 78-79.) For example, the specification states that the
`
`diagnostic system can “diagnose the vehicle’s own problems,” which includes
`
`providing an identification of specific components, e.g., tires, and providing an
`
`identification of whether those components need to be, for example, rotated or
`
`balanced, on the one hand, or replaced, on the other hand. (Id. at 19, 22.) Mr.
`
`Kennedy explains that one of ordinary skill would understand this to mean that a
`
`diagnostic or prognostic message is generated and includes identifying the
`
`
`2 Page numbers refer to the page numbers of the exhibit, not the page numbers of
`
`the specification.
`
`
`
`7
`
`
`
`Patent Owner’s Motion To Amend
`IPR2013-00417
`
`component and identifying whether the component needs to be repaired or
`
`replaced. (Ex. 2002 at ¶ 50.)
`
`The application also supports the overall combination recited by claim 22
`
`because, for example, the application states that the information discussed above
`
`can be sent to a dealer or other service center, e.g., a remote site. (Ex. 1007 at 19;
`
`Ex. 2002 at ¶ 50.) Additional support for the original limitations is also in the
`
`priority specification. (Ex. 1007 at 16-17, 28-31, 72, 78-79; Ex. 2002 at ¶ 51.)
`
`The priority application filed on June 7, 1995 provides similar disclosures
`
`regarding the invention recited in claim 22. (Ex. 2007 at 1, 4-6, 10-13, 15, 20-
`
`24.)3, 4
`
`
`3 Proposed dependent claim 23 is being amended solely to change the dependency.
`
`Support for claim 23 can be found in both applications. (Ex. 1007 at 12-13, 79
`
`(disclosing that the “triggering event” can be “failure, predicted failure, or fault
`
`code generation”); Ex. 2007 at 4-5, 10-11, 15-19; Ex. 2002 at ¶ 56 n.3.)
`
`4 The citations to page numbers in the priority application refer to the handwritten
`
`page numbers in the bottom margin. The fact that the application for the 788
`
`patent may have provided more detailed information regarding some of the claim
`
`limitations does not mean that the priority application is insufficient. See, e.g.,
`
`
`
`8
`
`
`
`Patent Owner’s Motion To Amend
`IPR2013-00417
`
`As discussed above, the limitations added to claim 24 are substantially
`
`similar to the limitations added to claim 22. For the same reasons as discussed
`
`above with respect to claim 22, support for claim 24 can also be found in the in the
`
`original-filed application that led to the 788 patent and the priority application.5
`
`V.
`
`PATENTABILITY OF THE PROPOSED CLAIMS
`
`The prior art cited in Toyota’s Petition and discussed below is the closest
`
`prior art of which AVS is aware with respect to the subject matter of the 788
`
`patent, including the added limitations of the substitute claims. (See Ex. 2002 at ¶
`
`57, 70.) Additionally, according to Toyota’s expert, the prior art cited in Toyota’s
`
`Petition is the closest prior art with respect to the subject matter of the 788 patent
`
`of which Toyota is aware. (Ex. 2003 at 26:4-9.) AVS also provides the
`
`declaration of its expert, Mr. Kennedy, who reviewed the prior art known to AVS,
`
`e.g., prior art from this and related inter partes reviews, prior art cited on the front
`
`
`Paperless Accounting, Inc. v. Bay Area Rapid Transit Sys., 804 F.2d 659, 664
`
`(Fed. Cir. 1986).
`
`5 Proposed dependent claims 25-31 are being amended solely to change the
`
`dependency. Support for these claims can be found in both the original and
`
`priority applications. (Ex. 1007 at 11-13, 16-19, 21-32, 79-80; Ex. 2007 at 4-5,
`
`10-11, 15-19, 22-25; Ex. 2002 at ¶ 56 n.3.)
`
`
`
`9
`
`
`
`Patent Owner’s Motion To Amend
`IPR2013-00417
`
`of the 788 and related patents, and references cited in invalidity contentions
`
`submitted by Toyota in the co-pending litigation.
`
`Claim 22 amends original claim 1 to recite that the monitoring for triggering
`
`events occurs “during operation of the vehicle on a road” and that “the diagnostic
`
`and prognostic message includes an identification of the at least one component or
`
`subsystem and an identification of whether the at least one component or
`
`subsystem should be either repaired or replaced.” Claim 24 likewise amends claim
`
`4 to recite that the diagnostic module monitors a plurality of different components
`
`or subsystems of the vehicle “during operation of the vehicle on a road” and that
`
`“the diagnostic or prognostic message includes an identification of the at least one
`
`of the plurality of different components or subsystems of the vehicle and an
`
`identification of whether the at least one of the plurality of different components or
`
`subsystems of the vehicle should be either repaired or replaced.” As Mr. Kennedy
`
`explains, performing this detailed level of diagnosis on-board an automobile was
`
`not known in the prior art in June 1995. (Ex. 2002 at ¶¶ 57-64.) Nor would one of
`
`ordinary skill in the art have been motivated to modify the prior art to arrive at the
`
`invention of claims 22 and 24. (Id. at ¶¶ 63, 66-68, 77-78.)
`
`The prior art in 1995 as it related to on-board vehicle diagnostics was
`
`primitive. As explained by Mr. Kennedy, in 1995 vehicles had sensors that
`
`provided information to the vehicle’s processor for use in operating the vehicle,
`
`
`
`10
`
`
`
`Patent Owner’s Motion To Amend
`IPR2013-00417
`
`e.g., in making the engine run. (Ex. 2002 at ¶ 61.) If the processor detected that
`
`the sensor output was outside a preset range, the processor could generate a fault
`
`code. (Id.) These fault codes provided minimal information—namely, that
`
`something was potentially wrong on the vehicle. (Id.) Fault codes were not being
`
`used in 1995 to pin-point the specific cause of the problem; rather they were used
`
`to narrow the scope of investigation with respect to the potential problem. (Id.)
`
`Thus, fault codes were not being used to, for example, identify whether a particular
`
`component needed to be repaired or whether the particular component needed to be
`
`replaced. (Id. at ¶¶ 61-62) For example, the fault codes could not tell you that you
`
`had to replace a certain component, as opposed to repairing that component. (Id.)
`
`The closest prior art in the automotive context of which AVS is aware
`
`discloses these types of basic automotive “diagnostic” systems. (See Ex. 2008
`
`U.S. Patent No. 5,157,160 to Asano (disclosing that “abnormal codes” and data are
`
`sent to a remote location for further analysis); Ex. 1002 (disclosing that “diagnostic
`
`codes” and data are sent to human expert for further analysis); Ex. 1004 (disclosing
`
`detecting an abnormality on the vehicle and sending data to a remote location for
`
`further analysis). Indeed, the prior art cited by Toyota and applied by the Board in
`
`this inter partes review disclosed these basic automotive fault code “diagnostic”
`
`systems. While this prior art disclosed things such as “abnormal codes” and “fault
`
`codes,” as Mr. Kennedy explains, these prior art systems would not provide
`
`
`
`11
`
`
`
`Patent Owner’s Motion To Amend
`IPR2013-00417
`
`information about whether the identified component needed to be repaired or
`
`whether it needed to be replaced. (Id. at ¶¶ 72-75.) Additionally, while there was
`
`some disclosure in the prior art of using a fault detection system to identify a
`
`component with a fault, again, those systems would not provide information about
`
`whether the identified component needed to be repaired as opposed to being
`
`replaced. (Ex. 2010, Wei Bin Zhang, “Vehicle Health Monitoring for AVCS
`
`Malfunction Management,” IEEE Vehicle Navigation & Information Systems
`
`Conference, 1993); Ex. 2009 (disclosing a diagnostic system for tires that only told
`
`you that there was a problem with a tire, not that it had to be repaired as opposed to
`
`being replaced); Ex. 2002 at ¶¶ 62, 76.)
`
`AVS is also not aware of diagnostic systems in 1995 in other applications
`
`that could identify whether any particular component needed to be either repaired
`
`or replaced. (Ex. 2002 at ¶ 78.) But even if such diagnostic systems existed, it
`
`would not have been obvious to use those systems in automotive applications.
`
`(Id.) As Mr. Kennedy explains, one of ordinary skill in the art in the automotive
`
`industry would not have looked to complex vehicular applications, e.g., airplanes,
`
`trains, when trying to solve an automotive problem. (Id.) That is because systems
`
`used on-board airplanes and trains are designed to operate in very different
`
`environments under very different considerations. (Id.) Thus, it would not have
`
`been within the ordinary creativity or basic skill set of those of ordinary skill in the
`
`
`
`12
`
`
`
`Patent Owner’s Motion To Amend
`IPR2013-00417
`
`art to look to complex aerospace or locomotive systems and modify those systems
`
`for use on automobiles.
`
`Nor would it have been obvious for one of ordinary skill in the art to modify
`
`the closest automotive prior art to arrive at the invention claimed in claims 22 and
`
`24. As explained by Mr. Kennedy, in 1995, processors were very expensive and
`
`processing and memory capacity on-board a vehicle was very limited. (Id. at ¶¶
`
`58-59, 64, 66-68, 77.) His opinions were confirmed by others. (See, e.g., Ex. 1002
`
`at 1:24-32 (discussing “on-board computing power limitations”).) As a result, in
`
`1995, those of ordinary skill in the art were not motivated to come up with
`
`solutions that involved adding such elements to the vehicle or that involved
`
`increasing the processing capacity of the processor on-board the vehicle. (Ex.
`
`2002 at ¶¶ 66-68, 77.) To develop an invention that could specifically identify
`
`components and identify whether they needed to be either repaired or replaced
`
`would have required adding elements to an automobile and would have necessarily
`
`required processing capacity on-board the vehicle that was not available in 1995.
`
`(Id.)
`
`The added features of the substitute claims would not have been within the
`
`ordinary skill in the art in terms of the ordinary creativity in 1995, e.g., a system
`
`on-board the vehicle that would be able to generate the specific type of diagnostic
`
`information of an identification of whether a component needed to be either
`
`
`
`13
`
`
`
`Patent Owner’s Motion To Amend
`IPR2013-00417
`
`repaired or replaced. (Id. at ¶¶ 63, 66-68, 77.) Moreover, the added features of
`
`claims 22 and 24 were not known in the art in June 1995, in either automotive or
`
`other applications, to AVS’s knowledge. (Id. at ¶¶ 70-78.) Nor as Mr. Kennedy,
`
`explains would a person of ordinary skill in the art have access to reference books
`
`in 1995 that would have taught a diagnostic system that could determine whether a
`
`specific component need to be repaired or whether a specific component needed to
`
`be replaced. (Id. at ¶ 63.) Rather reference books and conventional practice would
`
`have taught the basic fault code analysis that is described above. (Id.) A person of
`
`ordinary skill in the art in 1995 would not have been motivated to come up with
`
`the specific diagnostic system and method recited in claims 22 and 24. (Id. at ¶¶
`
`63, 66-68, 77.) Rather, those of ordinary skill in the art were motivated to think in
`
`terms of having a vehicle generate only basic faults codes because of, for example,
`
`the limited processing capacity of processors on-board the vehicle in 1995. (Id.)
`
`The invention of claims 22 and 24 was a significant advancement over the
`
`prior art. (Id. at ¶ 65, 69.) Despite the limitations in the art, the inventor of the 788
`
`patent figured out a way to move past the basic fault code diagnosis that was
`
`occurring on automobiles in 1995. His invention was a significant and useful
`
`advance over the prior art because having the vehicle conduct its own detailed
`
`diagnostic assessment allows for a more real-time diagnosis of the vehicle’s
`
`problems. (Id.) This in turn allows for the vehicle maintenance to be completed in
`
`
`
`14
`
`
`
`Patent Owner’s Motion To Amend
`IPR2013-00417
`
`a more efficient and timely manner such that vehicle breakdowns can be avoided.
`
`(Id.)
`
`
`
`In light of the above, AVS respectfully submits that proposed claims 22 and
`
`24 are patentable over the prior art. None of the prior art (including the closest
`
`prior art) recites an invention as recited by claims 22 and 24. Moreover, such an
`
`invention was not known in the prior art and would not have been an obvious
`
`modification over the prior art. Rather, providing a detailed diagnosis on-board the
`
`vehicle was a significant improvement over the prior art. AVS respectfully submits
`
`that dependent claims 23 and 25-31 are patentable over the prior art for the same
`
`reasons.
