Practice

Mr. Manspeizer focuses his practice on patent litigation, with an emphasis on the pharmaceutical and biotechnology industries. His experience combines seven years as Vice President of Intellectual Property and Associate General Counsel at top-ten pharmaceutical company Wyeth, and more than a decade as an intellectual property litigator in private practice.

From 2002 to 2009, as chief intellectual property officer for Wyeth, Mr. Manspeizer led a 140-person global IP department and was responsible for all of the company’s patent, trademark, copyright and trade secret matters, as well as IP litigation, diligence, counseling, IP aspects of transactions, and public policy for the corporate and pharmaceutical, consumer, and animal health divisions. While managing the department and supervising all outside counsel activities, Mr. Manspeizer supervised multiple simultaneous US and foreign patent and trademark litigations and directed a strategic patent portfolio focus that yielded a top ranking on the Wall Street Journal’s patent scorecard for eight consecutive quarters (2007–2009). He also led the legal team and negotiated settlements related to a multi-billion-dollar product subject to multiple ANDA challenges, and designed the litigation and settlement strategy for a third-party suit alleging patent infringement by a multi-billion-dollar product.

Prior to joining Wyeth, Mr. Manspeizer spent eleven years as an IP litigator at an international intellectual property law firm, where he was a partner since 1999. There, he handled pharmaceutical and biotechnology patent litigation in US district courts, the US Court of Appeals for the Federal Circuit, and the US International Trade Commission.

Mr. Manspeizer is admitted to practice before the Court of Appeals for the Federal Circuit and the United States Supreme Court, and is registered to practice before the United States Patent and Trademark Office.
