TAKE THE IPO STANDING IP COMMITTEE PROGRAM SURVEY TODAY
Please take a few minutes to complete the IPO Standing IP Committee Program Survey, which is now open to all IPO members, including current and former committee members and even IPO members who have never joined a committee.
Your feedback will inform improvements to how committees are structured, how members are recruited and onboarded, and how IPO can offer more flexible ways to get involved, from project-based work to asynchronous contributions. Committees are one of the most valuable ways members engage with IPO, stay current on IP law and policy, and connect with peers in IP law. We want to make sure the program works for you.
Take the survey here by Friday, September 4 to help guide the future of IPO’s Standing IP Committees.
