Re: Software rights Extending copyright after death has a benefit to in that it helps to discourage parties with deep pockets from stealing your copyrighted material. If you took the parties to court in a world without post mortem copyright, that party could keep you locked up in court 'til you die. (Sometimes, crime does pay.) Copyright extension beyone death ensures every stealer has to pay. I'm not saying the idea of post-mortem copyright is a good one, but it has a benefit.
