Patent office case law
According to a pro-free-software Venezuelan blogger, the patent office of Venezuela doesn't grant software patents. He also mentions that the patent office's computer systems run GNU/Linux, which is usually a positive sign.
Patents are granted based on the law "Ley. Art. 5 LPI.". The definition of patentable subject matter is in "Art.14. LPI" and exceptions to patentability are noted in "Art. 15". Possibly also of interest: Art. 22. LPI.
