This case involves the analysis of USB technology in multi-host capable devices. The plaintiff corporation holds various patents pertaining to multi-host capable USB device controllers as well as automatic switching between multiple USB host devices. The defendant company sells products which implement multi-host type USB devices in a “host to host” device that enables multi-host functionality. It was alleged that this “host to host” technology infringed upon the plaintiff’s patents. An expert in USB technology was sought to opine on the technology in question.
Question(s) For Expert Witness
- 1. Please describe your experience as it relates to USB technology and multi-host capable devices.
- 2. Have you ever served as an expert on a similar case?

I have 30+ years of experience in computer science and electrical engineering applications. I have been an expert on a similar case, and I have reviewed infringement matters. I was a testifying expert in a network communications case involving replication of USB port signals and I provided a report on patent non-infringement and invalidity for a dispute involving multi-host USB communications protocols. I have presented on communications with peripherals.

I worked within the group at a multinational technology company that invented and evangelized USBs. I have written 5 “How-To” books on USBs and run a consulting business in the area. I am familiar with all aspects of USB, including multi-host. I have reviewed similar infringement cases. I have also lectured and published regularly in the field and presented at industry and training seminars. The pertinent technology here seems pretty straightforward.
