The Case Law Blog, published by Delta Patents, focuses on developments and decisions related to European patent law. It covers topics such as procedural aspects before the European Patent Office (EPO), including oppositions, appeals, and interventions under the European Patent Convention (EPC). The blog discusses case law from the Boards of Appeal, including referrals to the Enlarged Board of Appeal on points of law like claim interpretation, patentability requirements, and procedural rules. It also addresses changes in EPO practice and regulations, such as notification and time-limit calculation rules, and procedural updates like the discontinuation of fax submissions. The content is aimed at practitioners interested in patent litigation, prosecution, and EPO procedural law.
