Get back to me when you start making sense. Speculation and patent trolling are two different things, and you are deliberately mischaracterizing the latter.
The goal of the patent system is to encourage innovation by providing the inventor/assignee a time limited right to prevent others from practicing their invention in exchange for fully divulging what the invention is and how to work it - so that when the patent expires all will have the knowledge and freedom to practice the claimed invention. The fact that some inventor/assignees can potentially sell their rights and recoup some costs can help stimulate their filing a patent on their inventions.
I agree that the “patent trolls” have provided value to the original patent holder, who for whatever reason has decided the value received is worth more than maintaining and attempting to enforce the patent on their own. Many inventors/small companies recognize they could never fund the enforcement of the rights granted by the USPTO, so they will sell those rights to someone who can.
The article’s comment that the patent system is somehow broken and discourages innovation is simply wrong. Lots of big companies come up with innovations and get patents they don’t practice for a variety of reasons. Some simply hold them as bargaining chips in case their competition asserts against them - they will have an arsenal to return fire, particularly if they think it’s something the other guy will be using. Likewise small inventors may have incentive to invent - and file the patent application explaining the invention if they know they may see some return even if they can’t bring the product to market.
