Andre Marais is a registered patent attorney and principal of Schwegman Lundberg & Woessner. He has been included in Intellectual Asset Magazine’s IAM 1000 listing of the world’s leading patent attorneys (2012-2016), and in the IAM Strategy 300 listing of the world’s 300 leading IP strategists (2016). Andre is passionate about architecting, building and managing patent portfolios with his clients. He takes the view that patent portfolios should be valuable, strategic assets that align with a solid business strategy. Having had the good fortune to work closely with a number of Silicon Valley’s most prominent software and companies since their early days, he brings an “in the trenches” perspective to portfolio strategy and growth.

His practice focuses on strategic IP counseling and patent prosecution (US and foreign), patent validity, infringement and clearance analysis and opinions, and IP due diligence work, particularly in the networking (including Internet), software, communications and electrical/electronic technologies.

He has secured patents for, and currently represents, a number of prominent technology companies based in Silicon Valley and elsewhere, including Germany and China. Andre is a frequent speaker on intellectual property topics and is a co-author of several intellectual property publications.
