I think software patents will continue also. I doubt the Supreme Court will overturn the 20 or so years that they have allowed patents, despite the opinions of a few vocal open source guys. For one thing it would completely destroy the patent portfolios of several major companies, throw considerable doubt on the patent portfolios of other corporations, and completely trash the economy even further. They also don't seem to be laying off examiners in the CS arts. What I'm hoping is that they'll raise the bar for CS applications and require more detailed claims and a more technical description. This would solve the problem with trolls and at the same time allow solid computer software patents (and the demand for the CS degree would sky rocket). One of the problems you have at the moment is that mechanical and electrical engineers that haven't ever written higher level code (compiler design, data structures, etc.) are writing and arguing the computer patents.
What would happen to CS attorneys if they do disallow computer software?
Assuming the economy has improved; they can get a job programming computers and open a solo practice on the side doing copyrights, computer law, etc. Or they can migrate to another practice area or possibly find work doing other types of patents. The lawyers with BA's in history or poli. sci. seem to be able to find some type of work.
If the economy worsens, there won't be any patent jobs unless you have an MS in EE and graduated from a top 10 law school, so who cares what degree you have. Now you can solo, do freelance programming, and apply to legal and technical jobs. Solo practitioners doing run of the mill stuff (debt collection, creditor's rights, foreclosures, DWI, family law, etc) can function quite well in a poor economy. It's the bigger organizations and corporate work that has the problems. Plus, you won't have to pay off your loans if the economy completely tanks.
Computer people will always be in demand so at least you'll have that going for you no matter what happens. That is assuming that unemployment hasn't doubled in three months like it has been.
Oh yeah, about the patent system being "broken." People have been saying this for the past 10 or so years. They also say it about practically every other area of law. Bankruptcy is broken because of X, criminal is broken because of Y, immigration is broken because of Z, etc. Are there some problems with patent law, yes. Does it work reasonably well, yes.
