Patent Trolls?

This article, discussing the recent conference titled "Patent Trolls and Patent Property Rights" begins:

Intel Corp's David Simon, chief patent counsel for the world's biggest computer chipmaker, recalls when he used to get only about five letters a year from people accusing Intel of patent infringement and demanding cash.

That was back in 1997. Now the Santa Clara, California-based company gets that many letters in a week, Simon said in an interview.

He even received one from the owner of a patent for a drill used to make a hacksaw blade.
