With recent government emphasis on fuel economy, which will be
discussed in more detail in the Hot Topics section, and a growing
market for hybrid and alternately powered vehicles, it is no
surprise that propulsion is a category of high interest to the auto
industry. Generally, all of the categories are seeing growth, but
none has experienced the rapid rise seen in propulsion.

Many of the companies in the top ten here are also in the
top ten overall since propulsion is the largest of all of the
categories. Notably, Hyundai is seventh in this category but
third overall, suggesting that propulsion may not be the major
focus of its portfolio.
In Navigation, Japanese electronics company Seiko Epson is
at the top of the field, joined by other electronics companies
including Semiconductor Energy Lab, Panasonic, Fujitsu
and Aisin.

In addition to developing categories within the automotive
industry, this study also looks at the organizations generating
the most innovations in each field. The companies that file
the most automotive patents represent the groups that are
investing the most in new technology, and provide a glimpse
into the areas of innovation in which they are most interested.
Figure 3 shows a chart of the top 25 most frequent invention
filers in the automotive industry.

TOP AUTOMOTIVE INNOVATORS
There are representatives from Japan (Toyota, Honda, Denso,
Seiko Epson, Mitsubishi), Korea (Hyundai), Germany (Bosch,
Daimler, Continental) and the United States (GM) in the top 10.
These companies represent 20 percent of all the filings that
take place within the automotive industry.

While Toyota is the top filer overall, and leads many of the
individual categories, it is listed fourth for the handling
category. This is contrasted with Hyundai, which is the top
inventive company in this category and plays a prominent role
in most of the other categories as well.

Returning to the individual categories, it is also possible to
identify the top companies in each of the more detailed areas
in the automotive industry. Figures 4 through 8 highlight the
top 10 companies within each category.

Looking at these categories over the past five years, as
seen in Figure 2, it can be determined that the main driver
for technology development in the automotive industry is
investment in propulsion systems.
