Competitor Infringes on Proprietary Imaging Technology

This case takes place in Arkansas and involves alleged patent infringement on technology used in a proprietary imaging device. The defendants are the inventors of various imaging technologies holding patents worldwide, including several U.S. patents. The defendant believes that the plaintiffs own imaging technology practices the invention covered under his multiple U.S. patents. According to the defendant, the accused product consists of a system of text generation and recognition technology whereby text strings can be generated and printed on documents with a unique security source code directly integrated into the printed text. A reading device can then be used to capture the text stings printed on the document and detect the embedded data, which syncs the document with a digital certificate of authenticity held by a third party. An expert in intellectual property (IP) was sought to opine on the issue.

Question(s) For Expert Witness

1. Are you familiar with dot pattern technology?

2. Are you familiar with the specific patent in question in this case?

3. Do you have industry expertise in the following: 1. optical imaging and distortion correction/control 2. data compression and data decoding algorithms (Assembly and C-code language) 3. printing technology re fine dots and dot patterns

Expert Witness Response E-008421

I would be happy to review this case, it seems very interesting. I am familiar with the technology and I have served as an expert in previous patent infringement cases. I earned a Ph.D in Optical Sciences from the University of Arizona, and am a Fellow of both the International Society of Optical Engineering and the Optical Society of America. I've won many awards throughout my career in recognition of my academic and research contributions. I have also published over 75 peer-reviewed journal articles, along with five textbooks. I am generally considered to be an authority in my field and I am frequently invited to lecture as a guest speaker. I am also the former President of the International Society of Optical Engineering.
