Revenue from the EDT Business
Revenue from the EDT business unit slightly decreased to $138.6 million in the first half of 2009 from $139.1 million in the first half of 2008.
Manufacturing revenue and royalties comprise revenue earned from products we manufacture for clients and royalties earned principally on sales by clients of products that incorporate our technologies.
Manufacturing revenue and royalties decreased 3% to $126.1 million in the first half of 2009 from $129.9 million in the first half of 2008. The decrease reflects the impact of the timing of customer orders. Except as noted above, no other single product accounted for more than 10% of our manufacturing revenue and royalties in either the first half of 2009 or 2008. For the first half of 2009, 46% (2008: 45%) of these revenues consisted of royalties received on products that we do not manufacture.
Potential generic competitors have challenged the existing patent protection for several of the products from which we earn manufacturing revenue and royalties. We and our clients defend our intellectual property rights vigorously. However, if these challenges are successful, our manufacturing revenue and royalties will be materially and adversely affected.
