IBM is the biggest patent troll. Ever. Who else do you think get $2 billion a year from patent trolling alone? Why do you think IBM has so many patents? Many of the patents are really silly, obvious and has broad coverage. IBM was always considered the big bad company, until Microsoft took over the crown, but IBM has never ceased to being bad. Have you followed IBMs ugly maneuvours in the Mainframe market? Horrendous stories. Every competitor is sued, or bought. Why is IBM called the "Big Blue"? Because they have so many lawyers in blue suits. More lawyers than engineers at one point in time. What do IBM use all those lawyers for? At IBM, a lawyer is more profitable than an engineer, that is why. It was really dumb by SCO to attack IBM for Linux patent trolling, IBM is the king of patent trolling. Really really stupid by SCO, they should know that no one can extract patent profit from IBM. IBM is the big extractor. IBM needed that Linux case, to polish the bad IBM reputation.
Sun Microsystems never cared about patents, until IBM nearly bankrupted Sun. After that, Sun started to patent everything and the engineers had a contest to get the goofiest patent. As told by James Gosling, father of Java:

"...In Sun's early history, we didn't think much of patents. While there's a kernel of good sense in the reasoning for patents, the system itself has gotten goofy. Sun didn't file many patents initially. But then we got sued by IBM for violating the "RISC patent" - a patent that essentially said "if you make something simpler, it'll go faster". Seemed like a blindingly obvious notion that shouldn't have been patentable, but we got sued, and lost. The penalty was huge. Nearly put us out of business. We survived, but to help protect us from future suits we went on a patenting binge. Even though we had a basic distaste for patents, the game is what it is, and patents are essential in modern corporations, if only as a defensive measure. There was even an unofficial competition to see who could get the goofiest patent through the system...."
Another patent trolling story where IBM attorneys black mail Sun: "Pay us $20 million or we will find some IBM patents you do violate and sue you"

"...My own introduction to the realities of the patent system came in the 1980s, when my client, Sun Microsystems--then a small company--was accused by IBM of patent infringement. Threatening a massive lawsuit, IBM demanded a meeting to present its claims. Fourteen IBM lawyers and their assistants, all clad in the requisite dark blue suits, crowded into the largest conference room Sun had.
The chief blue suit orchestrated the presentation of the seven patents IBM claimed were infringed, the most prominent of which was IBM's notorious "fat lines" patent: To turn a thin line on a computer screen into a broad line, you go up and down an equal distance from the ends of the thin line and then connect the four points. You probably learned this technique for turning a line into a rectangle in seventh-grade geometry, and, doubtless, you believe it was devised by Euclid or some such 3,000-year-old thinker. Not according to the examiners of the USPTO, who awarded IBM a patent on the process.
After IBM's presentation, our turn came. As the Big Blue crew looked on (without a flicker of emotion), my colleagues--all of whom had both engineering and law degrees--took to the whiteboard with markers, methodically illustrating, dissecting, and demolishing IBM's claims. We used phrases like: "You must be kidding," and "You ought to be ashamed." But the IBM team showed no emotion, save outright indifference. Confidently, we proclaimed our conclusion: Only one of the seven IBM patents would be deemed valid by a court, and no rational court would find that Sun's technology infringed even that one.
An awkward silence ensued. The blue suits did not even confer among themselves. They just sat there, stonelike. Finally, the chief suit responded. "OK," he said, "maybe you don't infringe these seven patents. But we have 10,000 U.S. patents. Do you really want us to go back to Armonk [IBM headquarters in New York] and find seven patents you do infringe? Or do you want to make this easy and just pay us $20 million?"
After a modest bit of negotiation, Sun cut IBM a check, and the blue suits went to the next company on their hit list...."

IBM threatens the Mainframe software emulator TurboHercules. Mainframe emulation is so successfull that you can emulate a midsized IBM Mainframe on a decent x86 server. This is not because the emulator is good, it is because the IBM Mainframe cpus are slow, they are much much much slower than a decent x86. This is the reason IBM shut down an emulator. Remember, emulating a foreign z12 cpu architecture is 5-10x slower than running native code on x86, but still IBM was afraid of it. If the emulation was too slow to be usable, IBM would not have bothered shutting down an open source emulator. IBM released 511 patents to open source community, to polish their bad reputation, but as soon IBM discovered TurboHercules used the released patent, IBM threatened to sue, and shut the emulator down completely. You can emulate an IBM Mainframe succesfully on your laptop, that is the reason IBM is afraid of emulators.
