Its do-able, but I am certain that the law of unintended consequences was written to describe situations like these.
For example, in your suggestion, the part where we move the onus onto the courts, will gum up the courts. I live in India, where courts are constantly arbiting cases, and people know that if your case gets into court, it could be there for ever. Thats not a side effect we want to induce.
Now you could build in redundancy for that eventuality by expanding the number of people in court, justices and areas, but then in essence, you are moving the burden from department X to department N, with the added problem that those new people will be from law, and not a technical background.
I really do think that this is a case where people should just get someone whos a technocrat in charge, give him authority and funds, and then forget about it while the patent office is built back up into an institution that people respect.
