"Excellent, professional and personal service that centres not just on providing patent filing/prosecution services and support, but also on offering strategic-level, nuanced IP advice that is specific to our situation and challenges."

"I like the IP service from Marks & Clerk because their response is always quick and to the point. Their daily communication is swift and smooth with an adequate depth of analysis. However, once any difficulty or trouble arises, they provide us with a very detailed analysis and with creative solutions."
