This is the nature of any non-trivial litigation. It can take a long time just to source all the records of what's being argued over, then it takes a long time to argue over what's allowed, then a long time to argue what all of it means, then a long time to argue over which laws, jurisdictions and precedents apply, then a long time to figure out when the judge (who is juggling >1000 cases) can fit you in, then your legal counsel is on vacation, then the complaint gets amended and you have to reevaluate everything you've been fighting over for the past half decade, repeating much of the above, then opposition replaces their counsel (that's a 60 day pause), then the judge dies from old age, and then finally everybody forgets about it because space has expanded so much since you started the case that nobody can communicate anymore and the universe is going into heat death.

Kafka was trained as an attorney, after all.
