How We Help Clients
Pre-Litigation Consulting
When Nortel Networks went out of business, its patent portfolio consisted of tens of thousands of patents, and competitors were bidding to grab large portions of it. Corporations with large IP portfolios often need help figuring out what exactly they have and how to monetize it.
Patent Infringement
Our experts have helped numerous parties in patent litigation to make sense of the technologies involved. We have opined on cases about telecommunications, as well as cases that relate to networking, such as contributory copyright infringement involving the DMCA.
Contract Disputes
High-stakes transactions require third-party independent experts to opine on critical technical aspects of the transactions. Top experts not only bring their technical expertise to answer questions, but also help drive the diligence process and define what questions to ask.
Case Studies
Patent Infringement
The patent holder was interested in analyzing the base station source code of several potential infringers. We worked with the already established claim chart to identify similar features in the source code and provided English language descriptions with citations of how and where the source code is exhibiting potentially infringing behavior. We also helped draft expert declarations.
Copyright Infringement
Our clients, the two largest bridalwear companies in the United States, complained that a cloud firewall provider enabled copycat manufacturers to commit copyright infringement by displaying our clients’ photographs. The case centered around DMCA safe harbors that rely heavily on the proper interpretation of computer networking technology terminology. We helped interpret the DMCA and put it into the proper technical context.
Patent Portfolio Evaluation
A large communications equipment manufacturer was interested in understanding the value of their newly acquired patent portfolio. We analyzed the asset by categorizing the patents by area of invention, organized them into sub-areas and families, and identified potential targets for assertion. As a second step, we analyzed a specific set of patent families against a specific target. We were able to identify sets of assertable patents across several patent families and assisted with creating initial claim charts.
