Some quick and dirty notes about DjVu patents. It seems to me that all them expired by now, but I am not sure.
Cf. also jwilk/didjvu#21.
I am not sure which license is appropriate for some texts included in the repository. If you notice a possible copyright violation, please report it in Issues.
I have neither time nor motivation to develop it further :-) Please consider this repository as orphaned. I would be only too happy to transfer the ownership of this repository to an interested person(s).
