`FORD 1207
`
`
`
`Case No: IPR2015-00758
`Attorney Docket No. FPGP0104IPR4
`
`attached as Exhibit 1220.
`
`6.
`
`I received my Bachelor of Science Degree in Mechanical Engineering
`
`from the University of Michigan, Ann Arbor in 1982 and my Master of Science
`
`Degree in Mechanical Engineering from Oakland University in 1986.
`
`7.
`
`8.
`
`I further am a licensed “Professional Engineer” in the state of Michigan.
`
`As shown in my resume, most of my career has been in the field of
`
`automotive engineering that includes numerous positions in both the academia and
`
`industry settings.
`
`9.
`
`After receiving my Master’s degree, I began work at General Motors
`
`where I had several assignments involving automotive design, advanced engineering
`
`and manufacturing. Over the course of my years at General Motors, I was involved in
`
`all aspects of the vehicle design process, from advanced research and development to
`
`manufacturing.
`
`10.
`
`Specifically, my work at General Motors included aspects of engine and
`
`fuel system design relating to the production of fuel sending units, and modeling the
`
`effects of fuels and EGR on vehicle performance and emissions.
`
`11. After leaving General Motors, I continued my education at the
`
`University of Michigan where I was awarded a Ph.D. in Mechanical Engineering in
`
`1991. My thesis was directed to automotive engineering, including the design and
`
`development of systems and models for understanding combustion in automotive
`
`engines.

`
`
`FORD 1207
`
`
`
`Case No: IPR2015-00758
`Attorney Docket No. FPGP0104IPR4
`
`12. Upon completion of my Ph.D., I joined the faculty of the U.S. Naval
`
`Academy where I led the automotive program in mechanical engineering. As part of
`
`my responsibilities while at the Academy, I managed the laboratories for Internal
`
`Combustion Engines and Power Systems.
`
`13.
`
`I further taught automotive and mechanical engineering courses while at
`
`the U.S. Naval Academy. Some of the courses I taught were directed specifically to
`
`design and operation of internal combustion engines in both conventional and hybrid
`
`vehicles. I also taught courses pertaining to the design and operation of hybrid
`
`vehicles.
`
`14.
`
`In addition to my work at the U.S. Naval Academy, I also served as
`
`faculty advisor for the USNA Society of Automotive Engineers (SAE). During this
`
`time I served as project director for the research and development of hybrid electric
`
`vehicles.
`
`15. My work with regards to hybrid electric vehicles included extensive
`
`design and modifications of the powertrain, chassis, and body systems. This
`
`development work included the design, modifications and implementation of alternate
`
`fuel delivery and injection systems.
`
`16.
`
`Some of the hybrid electric vehicle work that I worked on at the U.S.
`
`Naval Academy was published in a bound 1994 SAE special publication. I have
`
`attached as Ex. 1221 a true and accurate copy of the 1994 paper that was submitted
`
`on behalf of my team for this competition. (See e.g., Ex. 1221 at 6-11.)

`
`FORD 1207
`
`
`
`Case No: IPR2015-00758
`Attorney Docket No. FPGP0104IPR4
`
`17. While at the Naval Academy, I also taught classes in mechanical
`
`engineering at Johns Hopkins University.
`
`18.
`
`In 1995, I joined the faculty of Lawrence Technological University
`
`where I served as Director of the Master of Automotive Engineering Program and
`
`Associate Professor in the Mechanical Engineering Department.
`
`19. The master’s program in automotive engineering is a professionally
`
`oriented program aimed at attracting and educating practicing engineers in the
`
`automotive industry.
`
`20.
`
`In addition to teaching and designing the curriculum for undergraduate
`
`and graduate students, I also worked in the automotive industry closely with Ford
`
`Motor Company on the development of a hybrid electric vehicle.
`
`21.
`
`Specifically, I served as project director on a cooperative research project
`
`to develop and design all aspects of a hybrid electric vehicle. While in many instances
`
`we used standard Ford components, we custom designed many automotive
`
`subsystems. As part of this project, we completely redesigned and replaced the
`
`existing powertrain including the fuel storage, delivery and injection systems. We also
`
`did analytical and actual testing of the systems.
`
`22. While at Lawrence Technological University, I also served as the faculty
`
`advisor on several student based hybrid vehicle competitions that were sponsored
`
`primarily by Ford Motor Company, General Motors Company, and Chrysler
`
`Corporation.
`

`
`
`FORD 1207
`
`
`
`Case No: IPR2015-00758
`Attorney Docket No. FPGP0104IPR4
`
`23. These competitions required the complete design of hybrid vehicle,
`
`including the design of the powertrain. These competitions also required the complete
`
`design of the software and hardware required to control the hybrid vehicle.
`
`24. Attached as Exhibits 1222 and 1223 are true and accurate copies of the
`
`competition papers that were submitted for the 1996 and 1997 competitions for
`
`which I served as the faculty advisor. (Ex. 1222 & Ex. 1223.)
`
`25. During my time at Lawrence Technological University, I further served
`
`as advisor for 145 automotive graduate and undergraduate project students. Many of
`
`the graduate students whom I advised were employed as full time engineers in the
`
`automotive industry. This service required constant interaction with the students and
`
`their automotive companies which included the major automotive manufacturers (e.g.,
`
`Ford, Chrysler, General Motors, Toyota, etc.) along with many automotive suppliers,
`
`including those that supply fuel delivery systems (e.g., Denso, Delphi and Bosch).
`
`26. Currently, I am employed as a Professor of Mechanical Engineering &
`
`Director of the Advanced Engine Research Laboratory (AERL) at Kettering
`
`University—formerly known as “General Motors Institute.”
`
`27. At Kettering University I develop curriculum and teach courses in
`
`mechanical and automotive engineering to both undergraduate and graduate students.
`
`For one of my classes on automotive powertrains, a fellow professor (Craig Hoff) and
`
`I co-authored a textbook titled “Introduction to Automotive Powertrains.” A true and
`
`accurate copy of excerpts from this textbook is attached as Exhibit 1239. The full
`
`Page 12
`
`
`
`FORD 1207
`
`
`
`Case No: IPR2015-00758
`Attorney Docket No. FPGP0104IPR4
`
`version of this textbook is around 400 pages long and is used in my course to give
`
`engineering students an
`
`introductory understanding of the fundamentals of
`
`automotive engines, automotive transmissions, and how to select those components
`
`to provide the optimum compromise between acceleration performance, gradeability
`
`performance and fuel economy performance. (Ex. 1239 at 2.) Further, this textbook is
`
`based on my personal collection of class notes that I had been using to teach such
`
`fundamental automotive principles as far back as the mid-1990’s.
`
`28.
`
`Since coming to Kettering, I have advised over 90 undergraduate and
`
`graduate theses in automotive engineering. Further, I actively pursue research and
`
`development activities within automotive engineering.
`
`29. My work requires constant involvement with my students and their
`
`sponsoring automotive companies which have included not only those mentioned
`
`above, but also Walbro, Nissan, Borg Warner, FEV, Inc., U.S. Army Automotive
`
`Command, Denso, Honda, Dana, TRW, Tenneco, Navistar, and ArvinMeritor.
`
`30. As is further shown by resume, I have published over 50 peer reviewed
`
`technical articles and presentations involving topics in automotive engineering.
`
`31. Automotive and mechanical engineering topics covered in these articles
`
`include development of hybrid vehicles, mechanical design and analysis of
`
`components and systems, vehicle exterior design
`
`including aerodynamics,
`
`development of alternative fuel vehicles and fuel systems, thermal and fluid system
`
`design and analysis, selection and design of components and sub-systems for
`

`Attorney Docket No. FPGP0104IPR4
`
`optimum system integration, and system calibration and control.
`
`32.
`
`I have also chaired or co-chaired sessions in automotive engineering at
`
`many technical conferences including sessions involving powertrain development and
`
`control in automotive engineering.
`
`33. Additionally, while acting as director of the AERL, I am responsible for
`
`numerous laboratories and undergraduate and graduate research projects, which
`
`include On-road and Off-road engine and chassis testing laboratories. Projects have
`
`included the design and development of fuel injection systems for off-road vehicles,
`
`fuel compatibility studies of vehicle storage and delivery systems, modification of fuel
`
`delivery systems to accommodate alternative fuels, the development of electric
`
`vehicles, and other extensive modifications and development of vehicular
`
`powertrains.
`
`34.
`
`I also serve as faculty advisor to the Society of Automotive Engineers
`
`International (SAE) of the local Student Branch and for the “SAE Clean Snowmobile
`
`Challenge,” and “SAE Aero Design” collegiate design competitions. At the national
`
`level, I have served as a director on the SAE Board of Directors, the Engineering
`
`Education Board, and the Publications Board.
`
`35.
`
`Further, I have chaired the Engineering Education Board and several of
`
`the SAE Committees.
`
`36.
`
`I also actively develop and teach Continuing Professional Development

`
`CPD courses are directed to automotive powertrain, exterior body systems, hybrid
`
`electric vehicle design, and include extensive engine performance, emissions, and
`
`economy considerations. These courses are taught primarily to engineers who are
`
`employed in the automotive industry or governmental entities.

`
`Finally, I am a member of the Advisory Board of the National Institute
`
`for Advanced Transportation Technology at the University of Idaho. In addition to
`
`advising, I also review funding proposals and project reports of the researchers
`
`funded by the center.
`
`II. RELEVANT LEGAL STANDARDS
`
`38.
`
`I have been asked to provide opinions on the claims of the ’634 Patent
`
`in light of the prior art.
`
`39.
`
`I have been informed that a claimed invention is unpatentable if a prior
`
`art reference teaches every element of the claim. I have also been informed that a
`
`claimed invention is unpatentable if the differences between the invention and the
`
`prior art are such that the subject matter as a whole would have been obvious at the
`
`time the alleged invention was made to a person having ordinary skill in the art to
`
`which the subject matter pertains. I have further been informed that an analysis
`
`regarding whether a claim is obvious takes into account factual inquiries including the
`
`level of ordinary skill in the art, the scope and content of the prior art, and the
`
`differences between the prior art and the claimed subject matter.
`
`40.
`
`I have been informed that the Supreme Court has recognized several
`

`
`
`FORD 1207
`
`
`
`Case No: IPR2015-00758
`Attorney Docket No. FPGP0104IPR4
`
`rationales for combining references or modifying a reference to show obviousness of
`
`the claimed subject matter. Some of these rationales include the following: combining
`
`prior art elements according to known methods to yield predictable results; simple
`
`substitution of one known element for another to obtain predictable results; a
`
`predictable use of prior art elements according to their established functions; applying
`
`a known technique to a known device to yield predictable results; choosing from a
`
`finite number of identified, predictable solutions, with a reasonable expectation of
`
`success; and some teaching, suggestion, or motivation in the prior art that would have
`
`led one of ordinary skill to modify the prior art reference or to combine prior art
`
`reference teachings to arrive at the claimed invention.
`
`III. QUALIFICATIONS OF ONE OF ORDINARY SKILL IN THE
`ART
`
`41.
`
`I have reviewed the ’634 Patent, those patents cited in the ’634 Patent as
`
`well as the prior art documents. Based on this review and my knowledge of hybrid
`
`electric vehicles, including my work on multiple hybrid vehicles during the course of
`
`the 1990’s, it is my opinion that a person of ordinary skill in the art would have either:
`
`(1) a graduate degree in mechanical, electrical or automotive engineering with at least
`
`some experience in the design and control of combustion engines, electric or hybrid
`
`electric vehicle propulsion systems, or design and control of automotive
`
`transmissions, or (2) a bachelor’s degree in mechanical, electrical or automotive
`
`engineering and at least five years of experience in the design of combustion engines,

`

`
`
`Case No: IPR2015-00758
`Attorney Docket No. FPGP0104IPR4
`
`electric vehicle propulsion systems, or automotive transmissions.
`
`42.
`
`I have been informed that this determination regarding ordinary skill is
`
`made at the time of the invention, which I understand that the patentee purports as
`
`being the September 14, 1998 filing of U.S. Provisional Application No. 60/100,095
`
`(“the ’095 Provisional,” Ex. 1241). As I also discussed in my “Qualifications and
`
`Professional Experience” (¶¶5-37) above, I am familiar with the level of knowledge
`
`and the abilities of a person having ordinary skill in the art at the time of the claimed
`
`invention based on my experience in the industry (both as an employee and as a
`
`professor).
`
`IV. STATE OF THE ART
`
`43.
`
`It is my opinion that Hybrid-Electric Vehicles (hybrid vehicles) were
`
`conceived over 100 years ago in an attempt to combine the power capabilities of
`
`electric motors and internal combustion engines1 (ICE) to satisfy all the driver
`
`demand required to propel a vehicle. My opinion is supported by a true and accurate
`
`copy of excerpts from the 1998 textbook titled the “History of the Electric
`
`Automobile” authored by Ernest Wakefield. (Ex. 1224 at 11.)2
`
`
`1 An engine could also be referred to as a “heat engine” and is commonly known to
`
`be a part of the overall “Auxiliary Power Unit” of a hybrid vehicle (i.e., “APU”).
`
`2 Ex. 1224 is stated as being copyrighted in 1998 and available from the Society of
`
`Automotive Engineers (SAE). (Ex. 1224 at 2.)

`
`
`FORD 1207
`
`
`
`Case No: IPR2015-00758
`Attorney Docket No. FPGP0104IPR4
`
`44.
`
`For instance, Wakefield describes a functioning hybrid vehicle that was
`
`designed and built by Justus Entz in May 1897. (Ex. 1224 at 11-13.)
`
`45. My opinion is also supported by hybrid vehicle patents that I am aware
`
`of that extend as far back as 1909 for U.S. Patent No. 913,846 to Pieper that was
`
`granted for a “Mixed Drive Auto Vehicle.” (Ex. 1224 at 13-14.)
`
`46. As is explained by Wakefield, the hybrid vehicle disclosed by the Pieper
`
`patent was likewise assembled as a functioning hybrid vehicle that was publically used.
`
`(Id.)
`
`47. Also explained by Wakefield, well-known hybrid vehicles were built and
`
`publically used by Baker and Woods in 1917. (Ex. 1224 at 21-23.)
`
`48. Based on my experience and knowledge, well before September of 1998
`
`a known goal of using hybrid vehicles was the possibility of operating the engine at its
`
`“optimum efficiency.” For instance, a 1976 SAE paper states:
`
`From almost
`
`the beginning of
`
`the Automotive Age, various
`
`combinations of drive systems have been tried in order to achieve
`
`vehicle performance characteristics superior to those that can be
`
`obtained using a single type of drive. These efforts have been made in
`
`the name of many worthwhile goals such as increased vehicle
`
`acceleration capability, audible noise reduction, operation of an
`
`engine or turbine at optimum efficiency, reduction of noxious
`
`emissions, and improved fuel economy.

`
`(Ex. 1225 at 1, emphasis added.)3
`
`49.
`
`It is my understanding that based on events in the 1970’s, a renewed
`
`interest in hybrid vehicles emerged as a means to combat the U.S. dependency on oil
`
`and to meet increased air pollution reduction goals. (See e.g., Ex. 1226 at 3,4 Ex. 1227
`
`at 3.5)
`
`50.
`
`It is my understanding that in 1976 the U.S. government enacted Public
`
`Law 94-413 pertaining to the “Electric and Hybrid Vehicle Research, Development,
`
`and Demonstration Act” that was to “encourage and support accelerated research
`
`
`3 Ex. 1225 is a true and accurate copy of an SAE paper titled “Hybrid Vehicle for Fuel
`
`Economy” that was published by L.E. Unnewehr et al. that I understand was
`
`published on February 1, 1976.
`
`4 Ex. 1226 is a true and accurate copy of a SAE paper titled “Hybrid/Electric Vehicle
`
`Design Options and Evaluations” authored by Andrew Burke that I understand was
`
`published on February 1, 1992.
`
`5 Ex. 1227 is a true and accurate copy of a paper titled “Challenges for the Vehicle
`
`Tester in Characterizing Hybrid Electric Vehicles” authored by Michael Duoba that I
`
`understand was published by the U.S. DOE on August 1, 1997.

`
`into, and development of electric and hybrid vehicle technologies.” (Ex. 1228 at 4.)6
`
`51. As a result of this law, it is my understanding that multiple fully
`
`functional hybrid and electric vehicles were developed by automotive corporations.
`
`(Ex. 1228 at 4.)
`
`52.
`
`It is also my understanding that during the 1980’s and 1990’s, Ford
`
`Motor Company and Toyota Motor Company were involved in the design and
`
`development of both hybrid and electric vehicles. (See e.g., Ex. 1225 at 1; Ex. 12297 at
`
`4.)
`
`53.
`
`It is further my understanding that collegiate competitions intensified
`
`hybrid vehicle research during the 1990’s starting with the 1993 Ford Hybrid Electric
`
`Vehicle Challenge. As indicated by Ex. 1221, I personally participated in the 1993
`
`Ford Hybrid Electric Vehicle Challenge. (Ex. 1221 at 6.) By 1994 these collegiate
`
`competitions had grown to include teams from over 38 universities representing more
`
`than 800 students. (Ex. 1228 at 10.)
`
`54. As I mentioned in my “Qualifications and Professional” section above, I
`
`6 Ex. 1228 is a true and accurate copy of the “Electric and Hybrid Vehicles Program –
`
`18th Annual Report to Congress for Fiscal Year 1994” that I understand was
`
`published by the U.S. Department of Energy in April 1995.
`
`7 Ex. 1229 is a true and accurate copy of excerpts from a SAE special publication that
`
`I understand was published in February 1998. (Ex. 1229 at 2.)

`
`was personally involved with the U.S. Naval Academy’s hybrid vehicle design that was
`
`entered in the 1993 “Ford Hybrid Vehicle” and the 1994-1995 competitions. (Ex.
`
`1221 at 6.)
`
`55.
`
`I was also personally involved with Lawrence Technological University’s
`
`hybrid vehicle design that was entered in the 1996 and 1997 “Future Car” hybrid
`
`electric vehicle competitions. (Ex. 1222 at 6; Ex. 1223 at 10.)
`
`56. Based upon the level of research and development prior to 1998, it is my
`
`opinion that various hybrid vehicle “architectures” were well-known. (See e.g., Ex.
`
`1230 at 4 & 7-8)8. Hybrid vehicle “architectures” may also be generally referred to as
`
`hybrid “topologies” or “configurations.” As I explain in detail below, known hybrid
`
`vehicle “architectures” included what was commonly referred to as: (1) “series” hybrid
`
`vehicles (¶¶61-69 below); and (2) “parallel” hybrid vehicles (¶¶70-72 below). As I
`
`further explain in detail below, “parallel” hybrid vehicle architectures were further
`
`known to include: (1) one motor “parallel” hybrid vehicle architectures (¶¶73-86
`
`below); and (3) two motor “parallel” hybrid vehicle architectures (¶¶87-107 below).
`
`57. As I explain further below, these varying hybrid vehicle architectures
`
`differed in how the powertrain (i.e., the engines and motors) was arranged and
`
`
`8 Ex. 1230 is a true and accurate copy of an SAE special publication titled “Strategies
`
`in Electric and Hybrid Vehicle Designs” that I understand was published in February
`
`1996.

`
`connected to the wheels. The various architectures were done in order to achieve
`
`many of the goals I mentioned above in ¶48, including operating the engine at its peak
`
`efficiency. (See e.g., Ex. 1225 at 1; Ex. 1230 at 4 & 7.)
`
`58.
`
`It is my opinion that well before September of 1998 computer based
`
`microprocessor controllers were implemented to refine the control the engine,
`
`motor(s), transmission, and clutching mechanisms of the hybrid vehicle. For instance,
`
`my opinion is supported by a September 1988 paper which states:
`
`Automating the operation of a vehicle transmission allows the control of
`
`the engine and transmission system to be integrated, giving substantial
`
`benefits in terms of vehicle performance, energy efficiency and
`
`driveability. Although such a statement
`
`is applicable to
`
`internal
`
`combustion {ic} engine vehicles, electric vehicles and hybrid-electric
`
`vehicles the details relating to how the engine/transmission should be
`
`controlled are quite different. The main thrust of this paper is to
`
`consider the automa
