Nano Fuel Additives: Overview
• Nano Fuel Additive technology is a new concept of reduction of friction and wear through
the use of nanotechnology
• Transportation is one of the biggest sources of greenhouse gas emissions. Many people
have advocated a change in consumer behaviour as the best way to reduce
consumption. an approach which has seen more activity is on the fuel production side.
Fuel formulations and additive packs are now being designed to improve fuel
consumption and reduce harmful emissions
• Fuel additives have been one of the most prolific innovations of liquid engineering as
well as material science giving natural fuel sources additional properties which help us
drive that little extra out of them. Whether it’s an additive to alter a fuels burn rate,
increase surface area, prevent corrosive effects or simply color, innovators have
developed a range of additives over the years which give these fuels an added property
which serves a pressing need from consumers

Search Strategy and Sequence of steps
Using PatSeer database a sequence of steps was used to create search query. The table below shows sequence of steps we
followed. We combined keyword with relevant IPC, CPC, US and Japanese Classes to restrict the result set to relevant
records. The results were then collapsed by Simple Families. The publications included in the report are updated as of 15th
November 2014.

Highlights
• Charts are generated on overall number of records and Simple Families, using Patent
iNSIGHT Pro and PatSeer
• For analysis, records were categorized as different Nanoparticles, Applications, Types
• This report presents data:
 on the basis of different class (IPC/CPC/US/FI) for fuel additives and related
technologies
 across different companies, technologies in nano fuel additives

Publication Trend (By Individual Publications)
The chart shows number of patents and applications published in the last 20 years for all. The number of
applications published have steadily increased from 2006-2010 and tapered later. The decline in filings post
2010 is most likely due to unpublished applications.

Top Companies (By Individual Publications)
The chart shows top 20 companies by individual records in nano fuel additives. The count represents
the number of individual publications. It can be seen maximum records are owned by Cerion
Technology followed by Afton.

Top companies (Simple Family)
The chart shows records for top 20 companies collapsed by simple families in nano fuel additives.
The count represents the number of simple family members. It can be seen General Electric which
is not one of the top 20 applicants in overall publications appears in the top 20 in this chart. Same
holds true for Massachusetts Inst Technology.

Priority Country Map – Where is research being done ?
The map shows the geographical spread of patents first filed in nano fuel additives. It shows perfect
indication of where innovation is taking place. It can be seen US has 429 filings closely followed by
China and Japan with 273 and 50 filings respectively. The strength of the colouring represents the
proportion of patent publications.

Publication Trend across key countries in last 10 years
Chart shows year wise publications for key publication countries. It can be seen that publications in
US and China appeared around 2007 with a steady increase in 2010. There was an spike in
increase in publications in China whereas in US, these tapered off.

Companies across different Nanoparticles
The chart represents the technology spread of patent portfolios of top 20 companies across various
nanoparticles. The record count represents number of simple families. James K focuses in all
nanoparticles as compared to other applicants. It can also be seen that Chinese applicants are
predominant in research across different nanoparticles.

Top Companies across different types
The chart below shows research activity of companies across different fuel types. Diesel as a fuel type
is the most researched of fuel type. Universities and institutes are equally active across different fuel
types along with companies involved.

Top Companies across different applications
The chart below shows research activity of companies across different applications. Afton Corp leads
research across different applications even if Cerion Tech has more number of overall records.

Landscape for technologies used in nano fuel additives
The contour map below represents different technologies used in nano fuel additives with respect to complete patent portfolio.
Clusters for diesel based: clean diesel oil and methanol diesel oil are close to each other as there is high degree of relevance
between the records present in those technology areas. The patents represented by dots were coloured by company.

Summary
 There is considerable difference between the Chinese and US share in
application and patents. Chinese applicants accounted for the largest number of
patents filed throughout the world
 Only 5 (CN,US,JP,WO,EP) out of the total 17 patent offices have reported growth
over the last decade. China has recorded double digit growth between 2011-2013
 Nano particles is an area where companies have a scope of carrying out research
as most of the companies focus on few of the total nano particles used as fuel
additives
 In spite of the fact that Chevron has smaller portfolio than the major companies; it
can be seen that companies like Shell and UOP have cited its records indicating a
likely overlap in their R&D focus
