This article is much more about the evilness of patent trolls than about software patents.

My thoughts:

- Prevent the existence of trolls (for example by mandating that only patents that are central to your own business can be enforced).

- Raise the bar for the acceptability of software patents.

- Reduce the lifetime of software patents to something more in line with the software industry (a few years maybe).

But by all means, preserve software patents, they do have some value if used as they were designed for (protect companies that invest into R&D).
