 How drawings could enhance retrieval in mechanical and device patent searchingJane List World Patent Information, 2007, vol. 29, issue 3, 210-218 Abstract: In focusing on the field of searching mechanical and device patents, the author explores the available resources, their uses and their limitations. In contrast to searches in the field of chemical patents, this field does not usually provide the benefits of consistent terminology, deep level classification and indexing or direct searching of drawings (cf structural compound search in chemistry). The many challenging problems that result for the searcher and the state of the art in progress on direct searching of drawings are reviewed. Illustrative examples in the fields of medical inhalers and pump actuators are provided. It is clear that there is still a long way to go before practicable, searchable databases can be created or even one of the key initial steps in this process - the general filing and manipulation of 3D drawings in patent applications - can be realised. Methods of searching patent images and tools for faster evaluation of drawings in the full patent specification would be welcomed.
