David Walters practises exclusively in the field of patents. Having spent over 10 years in a legal department or law firm setting and over 20 in the patent industry, David has extensive experience with preparing and prosecuting patent applications in Canada and managing the filing and prosecution of patent applications worldwide. He also conducts patentability and infringement searches and opinions. His clients range from small enterprises to multinational corporations, both domestic and foreign, and the majority of his work is focussed within the communications and electronics industries. He is not only able to assist Canadian companies with obtaining patent protection at home and abroad but is also well-versed in advising clients in the United States and overseas on securing patent protection in Canada.

David assists clients with navigating every stage of the patent process from the initial identification of a need for protection through to patent issuance. He has experience with coordinating applications between Canadian and foreign patent offices and working with foreign associates as necessary. He also dedicates considerable time and resources toward fully understanding how to effectively meet the needs and objectives of his clients, and he collaborates with them through each step to ensure that their priorities are met and to mitigate any issues that may arise.

David has worked in the field of patents in several capacities through the course of his career. His time as a Canadian Patent Examiner allows him to offer unique insight into the potential challenges a client may face during the examination process. He has also worked as an in-house patent agent, which has afforded him experience with the patent-related concerns and challenges that can arise within a corporate organization.

With a keen awareness of the importance of staying updated on developments in patent law and practice, David maintains a constant effort to review update services, patent office announcements and communications from our extensive network of associate law firms, which enables him to apply the most current practices possible to the work he conducts on behalf of clients.
