Appeal No. 2003-1025 Application No. 09/224,918 to determine [perform the first process] [then perform the second process]." To determine whether claim 1 has an adequate written description, we must first determine what is being claimed. Our reviewing court states, "[t]he terms used in the claims bear a 'heavy presumption' that they mean what they say and have the ordinary meaning that would be attributed to those words by persons skilled in the relevant art." Texas Digital Sys. Inc v. Telegenix Inc., 308 F.3d 1193, 1202, 64 USPQ2d 1812, 1817 (Fed. Cir. 2002), cert. denied, 538 U.S. 1058 (2003). Upon our review of Appellants' specification, we fail to find any definition of the term "upon" that is different from the ordinary meaning. We find the ordinary meaning of the term "upon" is best found in the dictionary. We note that the definition most suitable for "upon" is "on".2 In turn, we find the ordinary meaning of the term "on" is best found in the dictionary. We note that the definition most suitable for "on" is "used to indicate occurrence at a given time."3 2 The American Heritage Dictionary, Second College Edition, 1982, page 1328.
