G1/24 - Small, But Perfectly Formed?The decision in G1/24 (Heated Aerosol) has now issued, and given the important principle of patent law involved, its brevity is impressive. At twelve pages in total including five pages of actual decision, this is among the shortest of the “short” Enlarged Board of Appeal decisions (in contrast to “long” decisions such as G1/19). “Short” decisions look to identify what question has to be answered and to provide as succinct an answer as possible, whereas “long” decisions look to tease out an answer to a complex question and often to give guidelines for applying the decision itself. G1/24 is the epitome of a “short” decision.
