Weil, Gotshal & Manges LLP

Weil, Gotshal & Manges LLP offers a truly comprehensive, national IP practice, encompassing patent litigation, technology and IP transactions and patent counselling.

Our patent litigation practice – which includes more than 40 attorneys in New York, Silicon Valley, Texas and Washington DC – is a trusted adviser to some of the world’s biggest names in the technology and life sciences sectors. When companies face important patent litigations and appeals – disputes where the stakes are high, the jurisdiction is unfriendly or precedent needs to be set (or broken) – they turn to Weil. We have extensive experience in all of the major patent litigation venues, including federal district courts, the International Trade Commission, the USPTO (where we have handled more than 200 inter partes review and covered business method review proceedings) and the Federal Circuit. In addition, our patent litigation team offers clients a deep, foundational understanding of their technologies, as many of our patent litigators have technical degrees and prior work experience in disciplines such as electrical engineering, computer science, mechanical engineering, chemistry and biology. Edward Reines serves as co-head of the patent litigation practice, along with Elizabeth Weiswasser and Brian Ferguson.

Our technology and IP transactions practice group comprises more than 20 lawyers in New York and Silicon Valley who spend 100% of their time on technology and IP transactions – a distinguishing feature of Weil – bringing deep expertise to client matters. We represent our clients – ranging from start-ups to Fortune 500 companies across a broad range of industries – in all stages of development. We are well known for our cutting-edge work in complex strategic transactions, licensing agreements, joint ventures, strategic alliances, R&D collaborations and outsourcing transactions. Michael Epstein is head of Weil’s technology and IP transactions practice.

Weil also offers a unique strategic IP counselling group, which provides a multidisciplinary approach to addressing IP issues for our clients, including patent portfolio analysis, IP management and dispute counselling, as well as IP transactions and acquisitions. With a keen understanding of the myriad IP issues facing our clients, our lawyers help clients to navigate the issues at hand, as well as anticipate how strategies in one area will affect efforts in another.

Clients of the group include 605, Altria, BASF, Dell, Dow Chemical, eBay, Eli Lilly, Facebook, FLIR Systems, General Electric, Globalfoundries, Illumina, Intel, Johnson & Johnson, L’Oreal, Lenovo Group, Life Technologies, Lubrizol, Micron, Nuance Communications, Oculus, Oracle, Pacific Biosciences, Sanofi, Stanford University, Tesla Motors, T-Mobile, Verizon, Under Armour, UnitedHealth and Yahoo.
