Catherine (Kate) S. Mayer is an Associate attorney within Merchant & Gould’s Alexandria, VA office. She focuses her practice on Section 337 litigation, helping companies protect their intellectual property and assets from unfair practices in importation and trade.

Focused on Section 337 Litigation

Section 337 concerns potentially unfair practices associated with the importation of products into the United States. And with so many products crossing our borders each day, companies require dedicated legal support to protect their rights.

As an IP attorney focused on Section 337, Kate helps businesses protect their intellectual property rights against unfair practices, including patent and trademark infringement and trade secret misappropriation. 

Having been a part of many successful cases before the ITC, most recently including investigations concerning patent infringement related to synthetic roofing underlayment products and trade secret protection related to lithium-ion batteries, Kate can provide the legal support you need to protect your IP and products. 

Since no business is immune to infringement, Kate supports businesses large and small in all industries.

Experience in Unfair Competition Investigations

Prior to joining Merchant & Gould, Kate spent two years practicing intellectual property and trade law in Washington, D.C., focusing on unfair competition investigations before the US International Trade Commission (ITC). She has also handled several trade secret cases, a rarity within the ITC. 

Kate’s early and focused experience in this area of the law is an uncommon accomplishment within the industry. Her additional experience includes leading training and discussions related to Section 337 strategy and procedure, as well as leading and assisting with depositions in Section 337 investigations.

From Paralegal to Litigation Attorney

Prior to becoming an attorney, Kate worked as a paralegal and legal recruitment specialist. As a paralegal, she was responsible for the preparation of complaints, motions, reports and more pertaining to Section 337 investigations. 

Her paralegal experience also included discovery, deposition, and trial preparation for high-stakes corporate litigations and arbitrations. With experience on both the client-facing and procedural sides, Kate understands the intricacies of IP law on a deeper level. Kate enjoys the challenges found in law and uses her past experience to solve them.

Kate received her Bachelor of Arts from the University of Pittsburgh. She then received her J.D. from the George Washington University Law School where she was a member of the Federal Circuit Bar Journal, Student Bar Association and Mock Trial Board and served as a student co-chair for the annual Cohen & Cohen Mock Trial Competition.

Supporting the Community

Kate also supports her community by dedicating time to pro bono work and volunteering. As an attorney, Kate has gained experience handling custody matters. As a student, Kate also volunteered at the local library and completed numerous service projects as a member of student organizations.

In her spare time, Kate enjoys indoor rock climbing, competing in Tough Mudder courses, travel, and reading.
