Stinson's patent attorneys advise chemical, pharmaceutical and biotechnology companies on every aspect of intellectual property law, including patent protection and strategy, enforcement and client counseling. We also defend clients against claims of infringement. We seek to understand the underlying commercialization aspects of our clients' technologies to develop specific intellectual property and business objectives. In addition to having the legal experience to protect critical intellectual property assets, many of our patent attorneys have advanced degrees and industry experience that provide for a deeper understanding of the science underlying our clients' discoveries.
