Kait Crowder's practice focuses on intellectual property, with a primary focus on patent litigation. She assists clients with defense and with protection and enforcement of intellectual property rights through court and administrative actions.

In the past two years, Kait has tried four cases for clients such as Johnson & Johnson and NXP in which she directed and cross-examined fact and expert witnesses. She also recently played a key role in achieving a Rule 12 dismissal with prejudice due to the asserted patent claiming unpatentable subject matter.

She has played central roles in achieving case-dispositive indefiniteness rulings during Markman proceedings and also has been a key contributor in other successful invalidity challenges, noninfringement defenses, and the preservation and limitation on the scope of liability and damages claims.
