Added matter or added subject-matter concerns the possibility to amend a patent (application). According to Art. 123(2) of the European Patent Convention (EPC), a European patent (application) may not be amended in such a way that it contains subject-matter which extends beyond the content of the application as filed. Adding subject-matter which is not disclosed would give an applicant an unwarranted advantage and could be damaging to the legal security of third parties. (G 1/93, OJ 1994, 541) The ‘gold standard’ of the European Patent Office’s Board of Appeal is that “any amendment can only be made within the limits of what a skilled person would derive directly and unambiguously, using common general knowledge, and seen objectively and relative to the date of filing, from the whole of the documents as filed” (G 3/89, OJ 1993,117; G 11/91, OJ 1993, 125).
In Brazil amendments to claims are possible if the patent applicant can show the changes are limited to the matter initially disclosed in the patent application (Article 32 of Patent Statute 9,279 of 1996). Thus, like most other countries, Brazilian patent law contains a prohibition against added matter. However, in a separate provision, the Brazilian…
