You can understand it when two such vast entities as Apple and Samsung start fighting, they'll fight over anything and everything.
However, now it seems that Samsung has annoyed that nice Englishman who makes extremely clever vacuum cleaners.
That large sucking sound you're hearing is the sound of Sir James Dyson wanting to breathe fire at Samsung for allegedly taking advantage of one of his patents.
As the BBC reports, Dyson took one look at Samsung's new Motion Sync vacuum cleaner and exclaimed: "Goodness me, that's my steering mechanism for cylinder cleaners!"
"It looks like a cynical rip-off," he told the BBC.
This is most odd, as Samsung has never been accused of cynically ripping off anyone's products. Oh, well, there was that one little case with Apple, I suppose.
Yes, there was another case in 2009, when a court insisted Samsung pays 600,000 British pounds (around $941,000) to another company for attempting to patent a "triple-cyclone" suction technology.
The victor in this case was, oh, look, Dyson.
However, this time around a company spokeswoman told the BBC: "The Samsung Motion Sync is an outcome of our own extensive research and development."
Dyson appears to be ready for a patent skirmish. He said: "We have been forced to issue proceedings in the English High Court, but I would much rather invest in research to develop new technology than have to sue."
You'd hardly expect him just to suck it up, would you?
