The complexities around patent law can be burdensome for companies looking to launch and grow, so it is important they have a strategic IP partner that allows them to focus on the bottom line. I strive to add true value to clients’ patent portfolios by leveraging my engineering background and expertise in intellectual property law. Doing so informs my ability to develop a unique, competitive patent roadmap for each client, establish solid and defensible patent portfolios, and execute on their patent strategies.
