Dow’s primary purpose in obtaining patents is to protect the results of its research for use in operations and licensing. Dow
is also party to a substantial number of patent licenses and other technology agreements. The Company had revenue related to
patent and technology royalties totaling $448 million in 2012, $437 million in 2011 and $191 million in 2010. The Company
incurred royalties to others of $185 million in 2012, $114 million in 2011 and $111 million in 2010. Dow also has a substantial
number of trademarks and trademark registrations in the United States and in other countries, including the “Dow in Diamond”
trademark. Although the Company considers that its patents, licenses and trademarks in the aggregate constitute a valuable
asset, it does not regard its business as being materially dependent on any single or group of related patents, licenses or
trademarks.
