Keywords: image-based PDFs, automated transformation, USPTO

Many governmental and private organizations gather massive collections of content, including legal documents, filings, and contracts. Most such collections consist of images and image-based PDFs; they’re not searchable or minable for the critical information that these organizations need to function. As data collections grow larger and are measured in terabytes, conventional conversion techniques—as efficient as they may be—are not economically feasible. The Holy Grail has always been a fully automated process without human intervention. This paper describes the implementation of such a system at the United States Patent and Trademark Office (USPTO).
