Sustainability: Impact of Patents
Degree to which the ability of archival institutions to
sustain content in a format will be inhibited by patents.
Although the costs for licenses to decode current standard
formats are often low, the development of open source
decoders will be inhibited.  Tools to transcode content in
these formats when they become obsolete may be more
costly to develop.
This factor was recently added to our list. We are
uncertain whether it will prove significant and welcome
the chance to discuss with others.
Examples:
Makers of tools for MPEG-1 moving image format do not [appear
to] require licenses
Makers of tools for MPEG-2 and MPEG-4 moving image formats
must pay for licenses and/or pass through royalties
