RATHER than name companies we could name behaviours or policies that impede GNU/Linux adoption. But companies which attack Linux using software patents are almost exclusively Microsoft, Apple, and Microsoft-tied entities such as Acacia.
Microsoft Marshals Dealmakers, Lawyers to Take On Android
[...]
On Monday, Microsoft CEO Steve Ballmer said he looks forward to collecting revenue from Android handset makers, including HTC, which has a licensing agreement with Microsoft.
The smartphone intellectual property wars are seriously heating up, as Motorola sided with HTC this week in an effort to cover its own rear. Remember those twenty patents Apple aimed at the Taiwanese OEM? Motorola says they're no good, and is trying to get them thrown out of court -- an important tactic, because if the patents do hold water and are successfully used against HTC, Apple might turn around and sue Motorola with them too. That's because there's more at stake here than OEM phones, but Android as a whole, and as such other manufacturers that implement Android might potentially be targets as well.
“Now they [Apple customers] can't type LOL, unless someone in authority puts it in a dictionary?”
--Pamela Jones, GroklawApple and Microsoft are both patenting limitations, i.e. they want a monopoly on attacking people's freedoms and basic rights. "Game console 'rejects' under-age players" says this new article about Microsoft and there are some other weird ideas thrown around at Microsoft, often to be patented sooner or later.
The good news is that Apple and Microsoft may gradually learn their lesson (Apple in Texas and Microsoft in Canada because of i4i for example). TechDirt asks, "Will The Supreme Court Review Patent Invalidation Standard In Microsoft vs. i4i Case?"
"Patent suit targets Apple, Microsoft, others over digital distribution" says this article from Apple Insider, so there is still some smacking going on. There is hope that patent trolling will increase so much that Apple and Microsoft too will decide to just abolish software patents [1, 2, 3, 4]. Check out the article "One Cheer for Patent Trolls":
As the Stanford paper suggests, in the vast majority of cases the authors studied the asserted patents were in fact junk, at least as determined at trial (judge and jury may have their own biases, of course). The inventors shouldn’t have gotten anything for them, either from the defendants or from the patent troll, because the patent never should have been granted in the first place. Again, the trolls may know better than the study suggests the real value of their holdings, and may be betting that the transaction costs of litigation will encourage defendants to settle anyway.
That bet is a game of chicken, for if the defendant chooses to litigate then both sides must absorb heavy litigation costs no matter who wins—the troll bets that the defendant will simply pay them to go away.
Patent trolls may make most of their money, in other words, from arbitraging the inefficiencies and failings of the current patent system.
Microsoft has received a patent that covers a search engine platform that is based on a "bag-of-words" and "essential pages" ranking system to make searches more efficient.
In Ex parte Venkata, App. No. 2009–007302 (BPAI, October 5, 2010), the Board held that “the claim’s body recites nothing more than software [and therefore] lacks statutory subject matter.”
