Executive Summary
The purpose of this study is to analyze the importance given by selected major automobile
companies in the electric car segment to innovation, based on their Patent Portfolios.
Apart from providing an account of innovation and technological development taking
place in the automobile, specifically to electric car segment, the analysis of the patenting
activity provides an insight into the current trends in the intellectual property generation
activity. The study summarizes results of the research that was conducted on Toyota
Motor Corporation, Tesla Motor Inc., The Ford Motor Company, Nissan Motor Company
Ltd and General Motors Company.
This report covers filing trends of the above mentioned companies along with status of
Patents, International Patent Classification and Priority Date. The study also provides the
filing trends and status in the field of engineering to which they belong, along with details
of all Patents filed by these companies since 2008.
The electric car industry is still in the nascent stage of growth. The electric car market is
majorly concentrated in US and Japanese market. There is an increasing trend in the
formation of Joint Ventures in research of electric battery technology by the automobile
companies. Electronic and electronic components manufacturing companies like
Samsung are filing patents in the electric car segment. This shows that electronic
companies are planning to enter the electric automobile market. Developing low cost
batteries, providing long range and government support are essential for success of
mass-market electric vehicle industry.
The major automobile companies have filed patents in electrical machinery and
transport segments. This shows that the investment is majorly done in battery and power
train technologies. Though Tesla motors started recently in 2003, it is competing with
top automobile companies like Toyota, Nissan, Ford and General Motors which were
established nearly 100 years ago. Tesla patents are referred by all the major automobile
companies and automobile component manufacturing companies. Tesla motors are
followed by General motors which show that GM considers Tesla a direct competitor
for the company in the electric car segment. Tesla motors did not cite any other patents
filed by other automobile companies. This shows that Tesla motors is leading other
automobile companies in technology research. Toyota motors have cited patents of all the
other major automobile companies which shows that Toyota is following technological
research of all the other major automobile companies.

Introduction
Automotive industry is one of the key sectors for all major countries in the world. The
automobile sales in 2013 have grown by 4.2% over sales in 2012 accounting to 82.84
million vehicles. The US (7.6%) and China have recorded highest growth in sales of cars
and trucks in the world. 1
The first electric vehicle was produced in 1930s. But the use of electric vehicles (EVs) was
replaced by petroleum-fueled internal combustion engines (ICEs) in 1900s. Because of
increasing and volatile fuel prices, deteriorating urban air quality and climate change,
renewed interest in the electric vehicles, stricter fuel regulations and to mitigate risk
from petroleum price fluctuations, the technology shift is accepted by the automobile
manufacturers. Alternate technologies include Battery electric vehicles (BEVs), Plug-in
Hybrid electric vehicles (PHEVs) and Fuel cell electric vehicles (FCEVs), Hydrogen cars
etc. Various governmental poli¬cies around the world are providing financial incentives
for vehicle electrification, setting standards for lower fleet-average fuel consumption and
even mandating the introduction of electrified vehicles.
Electric vehicles are rapidly emerging as a viable alternative to conventionally fuelled
vehicles. They are found to be one of the most promising ways to reduce emission of
greenhouse gases and other pollutants. The increasing demand in sale of electric and
plug-in hybrid vehicles has yet to create an impact. Though the sales of plug-in electric
vehicles have increased from 53,000 vehicles in 2012 to 90,000 vehicles in 2013, it
accounts for only 0.5 to 1% of the total cars and trucks sold in US in 2013.2
Electric
vehicles are mostly used as second vehicles by the people.

Investment in Research and Development acts as a good indicator for technological inno-
vation. Spending in EV RD spiked in US in 2009 due to economic stimulus and it spiked
in Japan and Germany in 2010 and 2011 respectively. There was significant increase in
RD in China in 2012. Within RD expenditure, there is relatively more focus on battery
and fuel cell RD. There is also significant funding in demonstrations of electric vehicles
reflecting government’s desire to monitor and learn from initial infrastructure and vehicle
deployment.3
Developing affordable batteries offering long driving range is the biggest
challenge to increasing sales of plug-in electric vehicles. Investment in battery and fuel
cell RD results in significant drop in battery development costs reducing cost barrier
for mass-market EV deployment. Four energy-storage technologies, Lead-Acid (Pb-Acid),
Nickel-Metal Hydride (NiMH), and Lithium-Ion (Li-Ion) batteries as well as Ultra capaci-
tors are used in current HEVs and are the only technologies of inter¬est for the foresee-
able future (10+ years).
There is an increasing trend in favor of filing of patents and safeguarding Intellectual
Property in electric vehicle industry by major automobile companies. The major areas
are the Electric machinery and Transport, together accounting for % of all patents filed
indicating an emphasis in improving battery and powertrain technology and conforming
to stricter environmental norms. This trend is only going to increase with environmental
concern becoming not only an obligation and responsibility but also a value statement
in itself.

The Automobile Sector- Segment-wise Market Share 4
About half of the world’s vehicles are produced by top nine manufacturers in U.S. The
electric automobile market is mainly dominated by developed markets like US, Japan,
France etc. The electric vehicle market in China is also steadily increasing. The sales of
electric vehicles in US and Japan cover 62% of the global market.5 Nissan Leaf and
Chevy Volt are top selling electric cars in the world. PHEVs have more market momentum
compared to BEVs indicating customers’ desire for fuel flexibility for greater range. There
has been recent increase in sales of BEVs like Nissan Leaf, Tesla Model S etc.

Scope of the Study Research Methodology
This study provides an insight into the Patent Portfolio of key global Automobile companies,
namely Toyota Motor Corporation, Tesla Motor Inc., The Ford Motor Company, Nissan
Motor Company Ltd. and General Motors Company.
The analysis looks at all the Patents applied by the above mentioned companies in
USA. This includes Patents at all stages – application, publication and granted - of their
lifecycle. For each company, the following data is presented in addition to the complete
list of patents filed:
• International Patent Classification (IPC), category wise Status
• Granted Patents and Pending Applications
• Timeline of Patent filings, year wise
• Citation analysis
Apart from a comparative look at these five Automobile companies and an insight into
the areas of possible patent generation, this report also highlights certain key aspects of
patenting for Automobile companies in the world.
Patent databases such as Thomson Reuter’s Delphion and several other Patent information
sites mentioned below were searched for Patents filed by companies indicated. As on
31st March 2014, records of all the Patent documents filed by the above mentioned
companies were extracted and analyzed. The results of the search have been tabulated
in Exhibits. The entire process was verified using multiple Patent databases to ensure
accuracy of the results. The Patent Database of United States Patent and Trademarks
Office (USPTO) were searched for ‘Live Patents’, and these results are also recorded in
the report.
It is important to note that the Patent applications filed during the last 18 months are
not reflected in the report since Patent databases only include patents in the publication
phase. In most cases, patent applications get published 18 months after the date of filing
as per the Patent filing norms except in the case of early publications, where they may
appear in the patent databases a little sooner. For this reason, all graphs indicate data
until and including the year 2008 only, to ensure uniform comparison across companies.

automobiles, trucks, and buses under the names Nissan and Datsun. The company also
designs and manufactures such products as communications satellites, pleasure boats,
and machinery. During the 1960s, when Nissan entered the world market, production
and sales grew phenomenally as the company established assembly plants in several
countries outside Japan. By the late 1990s, however, Nissan was struggling, and in 1999
it entered into a partnership with the French carmaker Renault.
Of the major manufacturers, Nissan has been the most aggressive in promoting all-
electric vehicles, not only in the U.S., but also around the world. By the end of 2012,
production of the Nissan Leaf and its battery pack was shifted from Japan to Smyrna for
the U.S. market, lowering production costs and better positioning Nissan to trim $6,400
from the base price of the 2013 model. Nissan also developed a more heat resistant
battery to address concerns of premature degradation and range loss in extremely hot
climates. The all-electric e-NV200 commercial van is scheduled for 2014 and a luxury
EV is planned with the Infiniti LE sedan. For the 2014 model year, Nissan also introduced
new hybrid technology with the Nissan Pathfinder.

Founded in : 1937
Chairman : Takeshi Uchiyamada
President and CEO : Akio Toyoda
Country : Japan
Toyota is the first automobile company to produce successful mass – produced hybrid car.
“The current capabilities of electric vehicles do not meet society’s needs, whether it may be
the distance the cars can run, or the costs, or how it takes a long time to charge.”
- Takeshi Uchiyamada, Vice – Chairman
The company concentrated mostly on the production of hybrid vehicles.
Toyota is the highest spending company in RD in the world. Tesla partnered with Toyota
to produce the Model S at the former NUMMI plant in Fremont, California, which opened
on October 27, 2010 and was rechristened the Tesla Factory.
In 2013, Toyota announced their intent to commercialize fuel cell vehicles and to bring
their first fuel cell vehicle to market by 2015. Toyota’s strategy for fuel cell vehicles differs
somewhat from other manufacturers; they are combining the efficiency benefits of their
electric Synergy hybrid system with a hydrogen tank and fuel cell stack. This provides
long-range electric operation and refueling times of about three minutes. Beyond the
dedicated Prius hybrid family, Toyota has expanded their hybrid Synergy drive throughout
their lineup in models like the Camry, Highlander, Avalon, and various Lexus models. For
full electric vehicles, Toyota worked with Tesla to develop the latest version of the RAV4
EV and they have also produced the Scion iQ EV, both of which were introduced as 2013
models with limited availability in California. The Toyota Prius, first introduced in 2000, is
by far the hybrid model with the most sales – about 220,000 in 2012 and 2013. Toyota
has a large line-up of hybrid models with eight different models sold in 2013. The Camry
Hybrid is Toyota’s second-largest hybrid seller. In 2005, Toyota began selling two hybrid
sport utility vehicles, the Lexus RX450h and the Toyota Highlander.

Appendix – I: Electric Car Market in India.
India is the world’s second-largest two wheeler manufacturer and fourth-largest producer
of commercial vehicles. Two wheelers dominate production volumes; in FY13, the segment
accounted for about three quarters of the total automotive production in the country.
Production of automobiles in India is growing at CAGR of 11.8 percent over 2005-13.
Passenger cars are the fastest growing segment, representing a CAGR of 12.9 percent6
.
Cost and Quality remain as bottlenecks of India’s auto industry in theto global marketplace.
Global OEMs like General Motors, Ford, Toyota and Hyundai have expanded their
operations over the past years. While Ford and Toyota continue to leverage India as a
source of components, Hyundai and Suzuki have acknowledged India as a key market
for a compact-car segment.
The electric vehicle market in India is nascent but growing rapidly. The total number of
electric two-wheelers on road is about 400,000 and about 1,500 electric passenger cars
in India. The availability of skilled engineers, low manufacturing cost and access to both
hardware and software uniquely positions India as a pioneer market for Electric vehicles.
So far only 2 companies were involved in Electric vehicle development in India, Mahindra
Reva (formerly Reva electric) and Tata Motors. The only major manufacturer and seller
of EV passenger cars in India is Mahindra-Reva, which opened a new plant and plans to
launch several new models to the Indian and overseas market. Similarly, the only seller
of passenger hybrid cars is Toyota Kirloskar. Lohia Auto manufactures electric 3-wheelers,
while there are quite a few electric two-wheeler manufacturers including Hero Electric
and Electrotherm. The Society of Manufacturers of Electric Vehicles (SMEV) estimates two-
wheeler makers and importers sold about 100,000 EV units in 2011, which would be
about one-tenth of the total scooters sold.
The combination of high fuel prices and government support is steadily increasing the
demand of Electric vehicles in India. In 2008, Government of India hads waived the
excise duty on electric vehicles and State governments have announced tax cuts to reduce
pollution levels in cities. Also in 2008, the Delhi government announced the subsidy of
29.5 percent discount for the small electric car Reva. Chandigarh government offered
a subsidy of 15 percent on battery-operated vehicles. Bangalore government gave 4
percent VAT waiver for the initial five years after the launch of the car and on registration
costs. The Government support is essential for success of electric vehicles. This is indicated
from the drop in sales of electric car Reva after the subsidy provided by the government
of Delhi wais cancelled.

The major challenges for implementation and adoption of electric technology in India
are:
• Needs Appreciation for definite guidelines and regulations and difficulties in
physical implementation.
• Needs Appreciation for electric vehicle charging infrastructure and quality and
availability of grid power.
• Low domestic availability of advanced electronics and controls and high-cost
of battery technology.
• Requires large investments and therefore considered high risk by stakeholders.
• Consumer acceptance and increasing awareness of the consequences of
buying EVs.
Government Incentives:
• In August 2012, the Government of India approved a Rs. 230 billion plan to
spur electric and hybrid vehicle production over the next eight years, setting
itself an ambitious target of 6 million vehicles by 2020.
• On the recommendations of the Prime Minister’s Group on Technology –
Manufacturing of Electric Vehicles in India, a core group was constituted by
the Department of Heavy Industry (DHI) in 2009 and a very elaborate
policy document was prepared. DHI took approval from the Government for
setting up the fully empowered apex body at a very senior level with
members drawn from all stakeholders, and for putting this initiative which
will encompass all policy related matters on various issues on a mission
mode approach.
• Accordingly, the National Council on Electric Mobility (NCEM) was set up.
Under the NCEM, a National Board on Electric Mobility (NBEM) was
proposed which would go into greater details of the various projects and
initiatives that need to be undertaken under this endeavor. Both the Council
and Board are serviced by a specialized technical secretariat seated in
National Automotive Testing and RD Infrastructure Project (NATRIP) and
the National Automotive Board (NAB).
• In the 2012 Union Budget, the Finance Minister announced a concessional
excise duty of 10% for fuel cell or hydrogen cell technology. The excise duty
on a CNG conversion kit has been reduced to 5%, while import of hybrid
parts has been exempted from custom duty and a concessional rate of 5%
excise has been proposed to incentivize their domestic production.
• Several initiatives including battery-operated Green rickshaws in New Delhi
and the Tata Starbus range of buses including hybrid CNG low-floor buses
have been introduced. Delhi has also subsidized sales by giving buyers a
15% rebate on the price of the vehicle.
