Ashley’s work spans contract disputes, indemnity actions, and a variety of IP disputes, including patent infringement actions and reexaminations, trademark and copyright matters, trademark opposition and cancellation proceedings, inter partes reviews, and disputes involving trade secrets, licensing, and contractual indemnity.

Ashley recently resolved a trademark dispute on the eve of trial for one of the world’s largest solar panel manufacturers after its internationally recognized brand and publicly traded stock symbol were accused of infringing the marks of a regional U.S. company, and helped win a motion to dismiss for an equipment manufacturer in a dispute involving false advertising claims. Other highlights include representing a technology manufacturer in a contractual indemnity dispute arising from underlying patent litigation and serving on the Willenken trial team that secured a $506 million judgment in a high-stakes pharmaceutical supply dispute in the Delaware Court of Chancery.
Before joining Willenken, Ashley practiced as a patent attorney in the Palo Alto office of an Am Law 50 firm and at IP boutiques.
