Testimonial

2026

"The longstanding cooperation between our two companies has resulted in a deep mutual understanding of requirements and our tasks."

"The high level of professionalism and the excellent network of law firms worldwide enable easy internationalisation of applications."

"Taking action by WSL Patentanwälte was prompt and professional, including outward communication towards patent offices as well as toward us as clients. We appreciated their proactive, supportive, success-oriented attitude. For instance when a patent was rejected, they informed us about follow-up possibilities and strategies. They were clearly engaged, it felt like a cooperation rather than just a paid service."

"We greatly appreciated their active presence throughout all aspects of the administrative process. For instance as one of our patents got rejected in a foreign land, with a possibility of appeal, we needed to find local legal advisors. The WSL team continued to support us and took initiative to solve problems."

"What we really like about WSL’s IP advisory service is how thoughtful and practical their advice is. They don’t just tell you what the law says, they explain what it means for your specific situation and help you figure out the best way forward."

"Their team is very responsive and easy to talk to. Even when the topic is complex, they break it down in a way that’s clear and useful. You can tell they have deep legal knowledge, but they also understand the business side of things."

Markus Zoller

"His attitude and communication skill are very good. I also would say, his comprehension is fast. He clearly made effort to understand the topic to the smallest details, which in fact may be important at some point. He also answered emails fairly fast, we always felt that attention was given."

Maximilian Knaus

"Dr Maximilian Knaus, and we simply call him Max, is a partner at WSL, and even though he’s young, he’s already made a strong name for himself. He truly understands the science behind the inventions, you can tell he shares the same excitement for technology and natural sciences as his clients do."
