A Very Good Thing Indeed.
"At present, trolls are sending out patent infringement claims to companies that own a fax machine or Wi-Fi network, and many pay up rather than going to court over the issue."
Not mentioned in the article is that any, many lawsuits are threatened, not only by patent trolls but all sorts of other attorneys as well, in many areas (i.e. product liability, all sorts of discrimination, libel and defamation, etc etc), based on the idea that the prospective defendant will prefer to settle as opposed to fight because it will be cheaper to settle than mount a defense. So this situation in is not really unique to the tech industry being threatened by patent trolls.
If they were to find a workable solution to this problem that could be implemented on a wider basis and which would benefit other industries in addition to the tech industry, it would be a very good thing indeed.
