For me, patent trolls are only a symptom and not the real problem. Patent trolls are a symptom of an overstretched patent system, where everybody (with enough money) can patent anything (also stupid and trivial stuff).
Where 50 years ago, one patent was made, 10 or 100 patents are made to secure any detail of the "invention". And many, many patents are made, that would have not have the smallest chance of been patented.
Remember: The patent application for the Z3 (one of the first computers) was denied. [1]
The problem is: How to distinguish small inventors (for which the patent system in former days should give security) which do not have the capital to produce their invention from so called "patent trolls". My fear is, that the legislation will fail to make a good enough distinction.
For big corporations it is a good thing to redirect the public agenda from the patent system to the smaller topic of "patent trolls". Big corporations that make many thousands patents a year, are also a part of the problem and not "patent trolls" alone.
