In an ideal world I'd like a distinct patenting regime for software - shorter patent lifespans, compulsory licensing on reasonable and non-discriminatory terms, a broader experimental use right encompassing most non-commercial users - but if the CAFC is just going to fold it into the maximalism of utility patents, why bother?
(His later novels, including Next, did drop slightly in quality as time went on, but Next is still a really interesting look at almost precisely the legal issue that you describe.)
The incredibly complete bibliography that you find in his novels of hundreds of citations just tends to prove out that frequently truth really is stranger than fiction. (For example, what if someone genetically engineered advertisements into the backs of sea turtles on barrier reefs?)
