Maysam Pessian is an associate in the Century City office of Wilson Sonsini Goodrich & Rosati. His practice focuses on patent prosecution and intellectual property counseling, serving clients in a wide range of technology fields, including the pharmaceuticals and biotechnology industries.

During law school, Maysam was an extern for licensing officers in the Invention Transfer Group at UC Irvine Applied Innovation. In this role, he performed a wide range of tasks, including preparing patentability and marketability reports on UC Irvine-owned technology; preparing targeted research reports on various private companies as a part of campus outreach efforts for collaboration; and drafting term sheets for technology licensing agreements and inter-institutional agreements. In addition, Maysam worked at the Domestic Violence Clinic at UC Irvine, where he represented victims of domestic violence in various proceedings and hearings to obtain temporary restraining orders, favorable financial terms, and permanent restraining orders in California Family Court.

Before embarking on his legal career, Maysam acquired extensive experience in immunology and neurobiology. Previously, he worked at an early-stage research company, where his work focused on various cancer vaccines and immunotherapies—specifically vaccina virus-derived oncolytic virus combination therapies. During graduate school, his research focused on the remodeling of the nervous system and functional recovery after spinal cord injury—specifically the effects of modulating Wnt-Ryk signaling. As an undergraduate, Maysam volunteered at the UC San Diego Moores Cancer Center as a research assistant in Boris Minev's laboratory, where he researched nanoparticle-delivered cancer vaccines.

On October 31, 2024, LuxWall, a leader in glass-based transparent insulation solutions to reduce energy consumption and carbon emissions from buildings, announced that it has closed a $51 million Series B funding round led by Climate Investment and Barclays Sustainable Impact Capital. New investors Carbon Equity and The Nature Conservancy participated in the round, alongside existing investors Breakthrough Energy Ventures, Prelude Ventures, 2150, Khosla Ventures, and Baruch Future Ventures. Wilson Sonsini Goodrich & Rosati advised LuxWall on IP and patent strategy in connection with the transaction.

The funding allows LuxWall to scale up production at its newly opened factory in Litchfield, Michigan, which received the support from Michigan Governor Gretchen Whitmer.
