The current Brazilian copyright law is Lei 9610/1998: Art. 43 specifies 70 years of protection for anonymous or pseudonymous works while case law related to Art. 11 + Art. 22 + Art. 24 + Art. 27 recognizes only Pessoas Físicas being as creator of intellectual works; Parágrafo único from Art. 40 sets the protection term for posthumous works. The effective law at URAA date was Lei 5988/1973, with Art. 44 setting 60 years of protection for anonoymous or pseudonymous works; the wording on corporate authorship was ambiguous: Art. 15 allows institutions or groups being credited for a work but articles such Art. 21 and Art. 25 states the irrevocability of moral rights; § 3º from Art. 42. was the responsible for setting the protection term for posthumous works.
