Michael (Mike) is a one of the country’s top patent litigators with a high-level background in technology and the Chair of the Litigation Practice for the firm’s Silicon Valley office. 

Mike has led teams for approximately 200 patent matters including in district courts, the PTAB, the Federal Circuit and the ITC. Mike is a first-call resource for many technology companies for their most significant and complex patent and related matters. Mike routinely counsels clients in the semiconductor, memory, telecom, medical device, networking, and virtualization spaces and has a strong focus on standards-based issues, crafting jury-friendly themes and litigating in Texas and Delaware courts.      

Prior to becoming a lawyer, Mike obtained nearly ten years of experience in industry, at Motorola focusing on trouble-shooting issues with high-tech instrumentation such as plasma etchers (as a semiconductor process technician) and in oil, gas and environmental labs focusing on mass spectroscopy and related instrumentation (as an analytical research chemist). 

Mike has guided clients through all stages of the litigation and PTAB post-grant processes, from pre-suit investigations to jury trials and ITC hearings, and through appeals of each up to the Federal Circuit. Mike has achieved great success for his clients across the country at trial and developing cases for trial, including obtaining key deposition admissions, arguing key motions winning claim construction (Markman) positions.

Mike has been featured in the Am Law “Litigator of the Week” column multiple times, including for achieving a jury trial win in a heated competitor case and an award of attorneys’ fees, treble damages and injunction post-trial. Mike has also achieved significant pre-trial victories for his defense clients including full exclusion of the plaintiffs’ damages expert reports in separate litigations and a summary judgment of no-available damages. Mike has argued in front of the PTAB multiple times and defended those wins on appeal at the Federal Circuit.

Prior to joining Winston, Mike focused on patent litigation at two nationally ranked firms in New York and Texas.
