Michael T. Rosato

Michael T. Rosato is a partner at Wilson Sonsini Goodrich & Rosati in Seattle, where he leads the firm's practice in contested proceedings before the U.S. Patent and Trademark Office (USPTO). His work centers on intellectual property disputes, with a pronounced specialty in post-grant proceedings, including inter partes review (IPR) and covered business method (CBM) reviews before the Patent Trial and Appeal Board (PTAB). His practice covers a wide array of technologies, including software, electronics, mechanical devices, and life sciences. Prior to joining Wilson Sonsini, Rosato was a partner at Kilpatrick Townsend & Stockton and began his legal career at DLA Piper.

Based on the provided data, Rosato's work is defense-oriented. In his single tracked district court case, he served as lead counsel for the defendant, Monolithic Power Systems, in a semiconductor patent suit brought by Greenthread Ltd. This litigation was stayed pending the outcome of IPR proceedings initiated by Monolithic Power Systems to challenge the validity of the asserted patents at the PTAB, a strategy consistent with Rosato's focus on post-grant challenges.

Rosato has extensive experience as lead counsel in numerous IPRs and other PTAB trials, frequently representing petitioners challenging patent validity. He has been recognized by various publications as one of the most active and leading attorneys for PTAB proceedings. His representative work in this area includes acting for clients such as Align Technology, Inc., Blue Coat Systems, Inc., and Sydnexis, Inc. in PTAB matters.

He received his J.D. from the University of Washington School of Law in 2002.
