Christopher L. May Profile Image

I am the head of the intellectual property practice at Massey & Gail LLP, focusing on patent and trademark litigation and Section 337 investigations before the International Trade Commission (ITC).  I handle patent litigation matters in a variety of technologies, including the pharmaceutical, mechanical and consumer electronic fields, and have experience in all aspects of patent litigation, including pre-litigation investigations, writing and arguing claim construction at Markman hearings, examining and cross-examining fact and expert witnesses, and management of litigation before both judges and juries at trial.  Some of my more significant cases from the past several years are as follows:

  • Certain Audiovisual Components and Products Containing the Same (Inv. No. 337-TA-837) (Fed. Cir.) – Successfully represented respondent Funai Electric Co. and its subsidiaries in an International Trade Commission investigation, resulting in finding of no violation and termination of the investigation in Funai’s favor. 
  • Estate of Martin Luther King, Jr. v. Martin Luther King, Jr. Center for Nonviolent Social Change (Ga. Sup. Ct.) – Represented the King Center in an action by the King Estate to terminate the Center’s right to use intellectual property, including the writings and spoken words of Dr. Martin Luther King, Jr., alleged to be owned by the Estate.
  • Veolia Water Solutions & Technologies Support v. Siemens Industry, Inc. et al. (E.D.N.C.) – Represented defendants in a patent infringement case concerning rotary disc filter technology. 
  • Shionogi v. Sandoz Inc. (D.N.J.) – Represented Sandoz in ANDA litigation concerning the drug doripenem.  The case was settled after briefing on claim construction.
  • Certain Integrated Circuits, Chipsets and Products Containing Same Including Televisions, Media Players, and Cameras (Inv. 337-TA-709, 786) (E.D. Tex.) – Successfully represented respondent Funai Electric Co. and its subsidiaries in a series of International Trade Commission investigations and subsequent district court litigation involving integrated circuits incorporated into Funai’s consumer electronics products, resulting in a finding of no violation and settlement on favorable terms.

In my free time, I teach classes on international intellectual property and patent litigation for the University of Maryland School of Law.  I am a native Washingtonian, and give back to my community by serving as a board member for DC Lawyers for Youth, and as a volunteer guardian ad litem for children in neglect and custody cases.

I am admitted to practice in the District of Columbia, New York, Southern District of New York, Eastern District of New York, the District of the District of Columbia, the U.S. Court of Appeals for the Federal Circuit and the U.S. Patent and Trademark Office.
