Abstract
This paper presents an overview of patents and patent applications on security embossed holograms, and highlights the possibilities offered by patent searching and analysis. Thousands of patent documents relevant to embossed holograms were uncovered by the study. The search was performed in the following databases: U.S. Patent Office, European Patent Office, Japanese Patent Office and Korean Patent Office for the time frame from 1971 through November 2005. The patent analysis unveils trends in patent temporal distribution, patent families formation, significant technological coverage within the embossed holography market and other interesting insights.
