Voice Tech's patents, according to their abstract, involve "receiving audio data from [a] mobile device at the computer. The audio data is decoded into a command. A software program that the command was provided for is determined. At least one process is executed at the computer in response to the command. Output data is generated at the computer in response to executing at least one process at the computer. The output data is transmitted to the mobile device."

All software patents are hardware patents since the program runs on the computer.
That's the loophole that the EPO has been using to allow software patents to be granted anyway, despite their exclusion in the law.
After the failed attempt to codify their practice in law in 2005, the large companies and the patent industry decided to install their own court, the Unified Patent Court, which might go live next 1st March.
They broke the rule of law as they needed the signature of the UK, with the blessing of the European Commission Thierry Breton, the guy who was ex-CEO of Technicolor, who made a fortune with MP3 patents.
In my opinion, this is like patenting putting a blue Lego brick on a red brick because nobody bothered to write down or patent that particular combination before. There's no core novelty here, and obviously Mycroft was not stealing profits from Voice Tech Corp.
Seems like a very very real reason to be horrified by software patents.
