Product Development 

We believe that our technology platform is essential to successfully implement our strategy of expanding and enhancing our services, 

expanding in the wireless and Internet software and application services market and maintaining the attractiveness and competitiveness of our 

solutions. We have invested significant time and resources in creating our patented and patent pending technology. Product development 

expenses were $39.3 million for the year ended December 31, 2001, $40.6 million for the year ended December 31, 2000 and $15.6 million for 

the year ended December 31, 1999.  

Intellectual Property 

Our success depends significantly upon our technology. To protect our rights, we rely on a combination of copyright and trademark laws, 

patents, trade secrets, confidentiality agreements with employees and third parties and protective contractual provisions. Most of our employees 

have executed confidentiality and nonuse agreements that transfer any rights they may have in copyrightable works or patentable technologies 

to us. In addition, prior to entering into discussions with potential content providers and customers regarding our business and technologies, we 

generally require that such parties enter into nondisclosure agreements with us. If these discussions result in a license or other business 

relationship, we also generally require that the agreement setting forth the parties' respective rights and obligations include provisions for the 

protection of our intellectual property rights. For example, the standard language in our agreement provides that we retain ownership of all 

patents and copyrights in our technology and requires our customers to display our copyright and trademark notices.

We have been issued six U.S. patents, and recently acquired twenty more in connection with the eCash asset purchase in February 2002. 

Our issued patents cover private label commerce solutions; tracking the purchase of products, services and information on the Internet and on 

wireless devices; and electronic transaction technologies. We also have several foreign patents and patents pending covering some of these 

technologies. We also have over forty nine U.S. patent applications pending relating to various aspects of our technology, including technology 

we have developed for querying and developing databases, for developing and constructing Web pages, electronic commerce on line directory 

services and Web scraping. We have received a notice of allowance for one of these patent applications. From the GiantBear asset purchase, we 

acquired three pending U.S. patents relating to wireless technology and through the eCash asset purchase, we acquired one pending patent 

related to electronic transaction technology. We are preparing additional patent applications on other features of our technology. We have 

instituted a formal patent program and anticipate on going patent application activity in the future. Patents with respect to our technology may 

not be granted, and, if granted, patents may be challenged or invalidated. In addition, issued patents may not provide us with any competitive 

advantages and may be challenged by third parties.
