Sridhar:

I thought that the Levicorpus and Lebiacorpus spells were Snape's 
discovery and James used it against him. Also, in the HBP when Snape 
and Harry are battling, Harry tries to use SectumSempra and 
Levicorpus on Snape, but Snape says,""You dare use my own spells 
against me, Potter? It was I who invented them - I, the Half-Blood 
Prince! And you'd turn my inventions on me, like your filthy father, 
would you? I don't think so . . . no"

If Snape had noted it down in his personal book and never used it on 
anyone, how could others get those spells? I deduced that James might 
have stolen it, but I could be wrong.

Sridhar:

I guess I have come to the group late enough to have missed the
deduction, having joined recently. I will search the archives, but if
you can point out the thread, I will be grateful.

Alternatively, if you can summarize the discussion using the canon,
that would be really great.
