No patent to the obvious
Foetus is a solo musical project of Australian composer and producer James George Thirwell.
Formed in 1981, Foetus' music can be described as Industrial or No-Wave while also incorporating orchestral elements.
In his song Instead… I Became Anenome, to be found on his album Ache, Foetus incidentally comments on the non-obvious criteria of patent law:
When is an indulgence not an indulgence? When it's a necessity There's no patent on the obvious, only on the seven deadly sins
However, I would contradict that only matters referring to the seven deadly sins are open to patent protection! In my interpretation, there is implicit criticism on the patent system in that technology is patented which can be harmful for mankind and in that patents can generally be harmful considering exploitation of poorer countries. A theme which is observed in other song texts as well, for example here ("Zeitgeist destroying grindcore").
In the song title, the writer purposively uses the word "anenome" which according to my research isn't an English word, but is often mentioned as a misspell of "anemone". Anemones, however, are either flowers or sea animals, the latter allowing only certain species to accompany them (like clown fishes). Possibly this ambiguity was intended, but in any event it's not obvious. The lyrics aren't obvious for the listener neither.
