Patent documents from the United States have a number of different types of citations associated with them. The majority of the citations are communicated between the examiner and the applicant via forms 892 and SB08. Form SB08 is better known as the Information Disclosure Statement (IDS) and is used by the applicant to communicate the prior art references that they are aware of. Form 892, on the other hand, is referred to as the List of References cited by examiner. This is the list of references identified during the examination process and represents the prior art used for the various office actions that take place during prosecution. In all cases, citations on Form 892 are hand-picked by the examiner, based on their relevance to the application at hand, and can be considered to be highly likely to be on the same topic as the case.
During this presentation, various methods, by way of a case study, will be explored for identifying and analyzing examiner citations coming from US patent documents including blocking citations that have been used in an office action during the examination of a subsequent patent application.
