Gary M. Hnath

A leading authority in the area of Section 337 litigation, Gary is a former president of the ITC Trial Lawyers Association and Chair of the ITC Committee of the American Intellectual Property Law Association and the ITC Committee of the ABA’s IP Law Section. He has lectured throughout the United States and Asia and written widely on the subject of Section 337 investigations. While working at the ITC, Gary was lead counsel for the government in Certain Concealed Cabinet Hinges, which raised issues of first impression as to what constitutes a “domestic industry” under the 1988 amendments to Section 337. He is also an Advisory Expert for China’s National Advisory Center for Overseas Intellectual Property Dispute Settlement.

Gary has successfully represented both patent holders and companies accused of infringement in cases involving a variety of technologies, including high-intensity sweeteners; coenzyme Q10; toner cartridges; sleep apnea products; laminated packaging; linear actuators; medical devices for vein harvesting; personal computers; acetic acid; wireless local area networks; ground fault circuit interrupters; agricultural vehicles; multiplexers used in space satellites; gear couplings used in industrial machinery; and neodymium-iron-boron magnets, to name just a few. He was lead counsel for the first company in China to win a Section 337 case after trial at the ITC. His recent notable victories for clients at the ITC include the successful defense of two manufacturers in China accused of infringing four process patents for the manufacture of sucralose. In this high profile case, the Commission found all of the asserted patents not infringed, and one of the patents invalid, after a hotly contested trial.

Gary has also represented numerous clients on a pro bono basis. For example, in a case for a Washington DC public school bus aide fired from her job as a result of an erroneous drug test, Gary was successful in obtaining a ruling that his client’s constitutional rights had been violated and an order reinstating her with back pay. The court’s decision in that case was cited for several years as one of the leading decisions in the US discussing the constitutionality of random drug testing.

A graduate of Harvard Law School, Gary previously served as law clerk to the Honorable Walter E. Black Jr., US District Court for the District of Maryland and a senior trial attorney with the ITC’s Office of Unfair Import Investigations.

• Toner Cartridges and Components Thereof - In 2018, Gary led the Mayer Brown team to a groundbreaking victory for Ninestar Corporation, located in Zhuhai, China, in a high profile case against Canon before the ITC. The ITC affirmed an administrative law judge’s summary determination of no infringement of all seven asserted patents related to laser printer cartridges. This victory was affirmed by the Federal Circuit in May 2020.
• High-Potency Sweeteners, Processes for Making Same, and Products Containing Same - In 2017, Gary led the Mayer Brown team in obtaining a favorable final decision from the ITC terminating the investigation in favor of China-based clients Anhui Jinhe Industrial Co., Ltd. and Suzhou Hope Technology Co., Ltd. We pursued early and aggressive discovery to challenge the basis for complainant’s infringement allegations, its purported invention and its own earlier sales as prior art. After two months, the complainant voluntarily withdrew its complaint, resulting in termination of the investigation and a complete victory for our clients.
• Backpack Chairs - Gary represented GCI Outdoor as respondent in a case alleging infringement of a patent on backpack chairs. After several months of litigation exposed serious flaws in its case, the complainant withdrew its complaint in 2017 and the investigation was terminated, a complete victory for GCI.

Immediately before the case was to go to trial, the Commission issued a notice that reversed the ALJ's initial determination and found that there was no violation of the consent order as previously alleged. Gary obtained interim review of the ALJ's order by flagging the issue for the Commission through a letter pre-institution. After Commission review and appeal, the Federal Circuit upheld our position that the electronic transmissions at issue were not “importations” and therefore outside of the ITC’s jurisdiction, representing a complete victory for our clients.
• Toy Figurines and Toy Sets Containing Same - Gary was lead counsel for Mega Brands as respondent in a case brought by Lego alleging infringement of design patents and copyrights on Lego’s popular toy figurines. The case settled favorably in 2015, with no admission of liability, after initial discovery exposed significant flaws in Lego’s case.

Gary’s team also helped the client in successfully designing around the remaining patents. Ultimately, after an appeal to the Federal Circuit and remand to the Administrative Law Judge, Gary’s client in China prevailed on all seven patents.
• Kinesiotherapy Devices and Components Thereof – Gary represented as co-counsel the complainant in a case involving couples devices. Following trial, the ALJ found that the patent was valid and infringed, but that there was no domestic industry. After filing a petition for review and further briefing, the Commission reversed the finding of no domestic industry, found a violation of the statute, and issued a general exclusion order excluding all infringing devices from being imported into the US, regardless of source. The decision on domestic industry was reversed on appeal to the Federal Circuit in 2015 but the findings on infringement and validity were affirmed.

• Certain Products Having Laminated Packaging – In 2013, Gary represented the lead respondent in a case involving laminated packaging. The ITC, for the first time, instituted a new procedure requiring the ALJ to decide the issue of domestic industry within 100 days, subject to immediate Commission review. The ITC later indicated that this would be the first case in a new pilot program to streamline ITC procedures. The ALJ ruled in favor of respondents, finding no domestic industry, and the ALJ's decision was affirmed by the Commission, resulting in termination of the investigation with a finding of no violation.

After three months of vigorous defense on behalf of Sopo, Gary’s team exposed major flaws in the complainant’s infringement allegations and serious questions about the validity of its patent. In June 2008, Celanese voluntarily withdrew its complaint before the ITC, resulting in a complete victory for Sopo.
• Sucralose, Sweeteners Containing Sucralose, and Related Intermediate Compounds Thereof - In 2008, Gary led a team in obtaining a complete victory at the ITC for Niutang Chemical, located in Changzhou and Guangdong Food Industry Institute. The case involved the top selling artificial sweetener in the world, sucralose, sold in the US as Splenda, and the complainant was a huge British competitor, Tate & Lyle, which produced Splenda. After extensive discovery and a hard-fought two week trial at the ITC, the administrative law judge ruled in favor of the two Chinese respondents, finding that there was no infringement of any of the four asserted patents, and that one of the patents was also invalid and not being used by the complainant.
