Cyber Security Experts Discuss Alleged Intellectual Property Infringement by Network Security Firm


cyber security expert witnessThis case involves a patent that was issued to the plaintiff in the early 2000’s for controlling and mediating access to the internet from private computer networks. The patent described a number of different features that enabled network administrators to control the kind of content users on their private network would have access to, manipulating firewall-to-firewall encrypted settings as well as a number of cyber security features that prevented malicious user actions from penetrating the private internal network. Some years later, a competing service emerged offering a product that boasted a number of similar features, a product that was described as a “network traffic and content mediation system.” While some of the methods in which the competing company’s product provided their security services differed from those of the plaintiff company, it was alleged that the overall architecture of the program infringed on the plaintiff’s original patents for the 2000’s, which were still in effect when the competing product was launched.

Expert Witness Response E-090926

I am a Professor and my research is directly focused on web/content filtering. My dissertation was about how to use trust in social media to filter web content, and I have built my own web content filtering systems. All of these were academic projects – I have no commercial interest in this space. I have been a Chair and Advisory Board Member for the ACM Recommender Systems conference, the main academic community that does this kind of filtering. I also study cyber security and am part of a prominent academic cybersecurity organization. I have been an expert on a number of intellectual property-related cases, several of which are patent cases.
