PATENT CLARIFICATION NOTE

Adobe has a number of patents covering technology that is disclosed in the
Portable Document Format (PDF) Specification, version 1.3 and later, as
documented in PDF Reference and associated Technical Notes (the
Specification). Adobe desires to promote the use of PDF for information
interchange among diverse products and applications. 

Accordingly, the following patents are licensed on a royalty-free, non-exclusive
basis for the term of each patent and for the sole purpose of developing software
that produces, consumes, and interprets PDF files that are compliant with the
Specification: 

U.S. Patent Numbers: 

	5,634,064
        5,737,599
        5,781,785
        5,819,301
        6,028,583 

In addition, the following patent is licensed on a royalty-free, non-exclusive basis
for its term and for the sole purpose of developing software that produces PDF
files that are compliant with the Specification (specifically excluding, however,
software that consumes and/or interprets PDF files): 

U.S. Patent Number: 

	5,860,074 

The above licenses are limited to only those rights required to implement the
Specification and no others. That is to say, Adobe grants only those rights in the
above patent(s) necessarily practiced to implement the Specification, and does not
grant any rights not required to implement the Specification. The licenses do not
grant the right to practice any patent covering other technologies, such as
implementation techniques that are not explicitly disclosed in the Specification, nor
does it allow the use of any patented feature for any purpose other than as set
forth in the applicable license grant. Adobe has other patents in various fields,
none of which are hereby licensed.
