  • agricultural biology;

Our deep bench of IP litigators is experienced in prosecuting and defending claims of patent infringement for a broad range of industries, including biotech, consumer products, electronics and software. We always focus first on our clients’ goals. Our philosophy is to resolve disputes in the smartest, most cost-effective and expeditious way. In patent cases, a path to victory is often carved out in the early stages of the case where rulings on claim construction and the scope of expert testimony can frame the issues in a decisive way.

Our patent prosecutors and patent litigators effectively resolve disputes before the Patent Trial and Appeal Board (PTAB), USPTO and federal, state and appellate courts and are primed to represent clients before the PTAB. We have a track record of success in handling inter partes reviews.

In addition to offering the full range of IP services to our clients, our attorneys routinely perform due diligence reviews in connection with corporate transactions in which IP rights are involved and conduct IP audits and evaluations, assessing where a company may be at risk or may have an opportunity to maximise its intellectual capital.

Fox is consistently recognised for excellence in our IP work. Recently, IP Today ranked Fox among the top 40 law firms in procuring US trademark registrations; Best Law Firms in America ranked Fox among the top metropolitan tiers in both the patent law and patent litigation categories; James Singer, chair of Fox’s IP department and Gerard Norton, chair of the IP litigation practice group, were both named in The National Law Journal’s list of trailblazers in intellectual property; and Michael Leonard, chair of Fox’s trademarks practice, has been recognised in the WTR 1000 for seven consecutive years.
