Sukontip Jitmongkolthong is a partner in the Tilleke & Gibbins intellectual property group. An expert in trademark, copyright, patent, and trade name legislation, Sukontip is routinely selected by international corporations for her proficient enforcement of valuable IP rights, with a focus on apparel, automotive, electronic, and fashion products, among other industries.

Her work includes pre-litigation assistance in cancellations and appeals against Board of Trademarks decisions, reviewing and/or drafting nondisclosure agreements and warning letters, mediation and negotiation, and coordinating with investigators, the Royal Thai Police, the Department of Special Investigations, and Customs in raid actions and other enforcement measures. Sukontip also frequently trains government authorities on product identification and is steadfast in making sure they continue to monitor Thailand’s borders, ports, and marketplaces for counterfeit goods bearing our clients’ marks.

Sukontip is an active member of the International Trademark Association (INTA), and sits on the Famous and Well Known Trademarks Subcommittee. She obtained her most recent professional training in Cross Border Technology Transactions from the Lex Mundi Institute in Monterey, California, and has also completed training in arbitration and patent law. She has also completed the Barrister-at-Law requirements of the Institute of Legal Education, Thai Bar Association.

  • Discovered that a company was using our client’s company name and trademark  without authorization. We sent a cooperation letter to the infringing company asking it to cease using our company’s name. Within one week of issuing the letter, the company agreed to change its name.

  • Protected the intellectual property rights of a famous drug company in regard to an osteoporosis drug product passed off by another pharmaceutical company. The Supreme Court ordered the cancellation of the infringing party’s mark.

  • Proved infringement and secured out-of-court settlements against several internationally connected companies that were infringing our client’s patents. Our proof was derived from our investigation of the Thai market, acquisition of the infringing products, and extensive infringement analyses. The settlements included monetary damages, public acknowledgement of infringement in local newspapers, and binding commitments to stop importing the infringing products into Thailand.

  • Represented a multinational pharmaceutical company in opposing the trademark registration of a mark for a generic nasal spray based on the mark’s similarity to a registered trademark. The Registrar rejected the trademark application.

  • Represented the top U.S. direct sales company in Thailand against a Thai company that filed a criminal case and a civil case seeking damages for alleged wrongful acts and loss of reputation.

  • Represented a leading Japanese electronics company in a patent infringement case against a Thai distributor which concluded in an amicable settlement through mediation in less than one year. The settlement included the seizure and disposal of existing counterfeit inventory, an agreement to stop the sale and marketing of counterfeit products, and a marketing awareness campaign educating the public on the differences between authentic and counterfeit products.

  • Acted on behalf of a Swedish bearing manufacturer in cooperation with the Department of Special Investigation to conduct a raid action against a local company that was distributing counterfeit bearings to unsuspecting consumers. The raid, which took place near Bangkok, resulted in the seizure of 16,530 counterfeit products, which included more than 300 fake bearings worth over THB 10 million.

  • Prepared and sent warning letters to three companies requesting that they stop using our client’s trademark on their products. All three companies complied with our demands and stopped the infringement.

  • Assisted a Thai food processing conglomerate to conduct its annual anti-counterfeiting campaign in Laos, which covers seven provinces including Vientiane, Champasak, Ta Kaek, Savannakhet, Salawan, Udomxai, and Luangprabang. The campaign targets shops selling counterfeit monosodium glutamate, and thus far, thousands of counterfeit products have been seized.

  • Provided assistance to a Thai agricultural machinery company to initiate an administrative action in Laos against retail shops selling counterfeit lubricant products in Vientiane and Savannakhet. The administrative action created consumer awareness of counterfeit products. In addition, hundreds of counterfeit lubricant products were seized, and the results of this administrative action were published in local newspapers in Laos.
