Making innovation commercially disadvantageous
Nokia's 2007 position paper regarding video codecs in the w3c's HTML5 standard suggested using software from 20 years ago:
A second alternative would be the reference, as a baseline, of older media compression standards, of which one can be reasonably sure that related patents are expired (or are close to expiration). One example for these codecs is ITU-T Rec. H.261, which (in its first version) was ratified in November 1988. While not competitive with today’s state of the art codecs, it’s in the author’s personal experience not that far in its performance from [...] The disadvantage of this approach is clearly the use of technologies that are two decades old, but that may be at least partly offset by the commercial advantage.[1]
(emphasis added)
So, due to software patents, Nokia sees a commercial advantage in using technology from 20 years ago.
