Experience

The project lasted for three years and successfully handled hundreds of adverse parties through different strategies and approaches, compelling them to cease the infringement.
  • Advised and assisted a U.S technology company in a complex campaign against many corporate users infringing on the client’s software copyrights, compelling them to purchase licensed products from the client. The project helped the client recover hundreds of thousands of dollars from the infringing parties.
  • Assisted and represented a British apparel manufacturer in a civil lawsuit before the Ho Chi Minh City Court against a local manufacturer who continued producing items that infringed the client’s trademarks despite being subject to a previous administrative sanction. The judgment ruled in favor of the client, compelling the defendant to stop the violation immediately.
  • Advised and assisted a New Zealand agricultural company in a case where multiple local sellers were trading in a Chinese product infringing the client’s plant variety rights and conducting acts of unfair competition with the client’s product.
  • Advised and assisted a Chinese entertainment corporation in an enforcement program against food and entertainment service providers who applied the client’s trademarks and trade name in their business without authorization.

Intellectual property experts from Tilleke & Gibbins were engaged by ARISE+ IPR, a regional support program funded by the European Union and implemented by the European Intellectual Property Office, to craft a series of IP enforcement guides for Southeast Asian countries, aimed at raising local awareness of the importance of IP protection. The five-year, EUR 5.5 million ARISE+ IPR program supports regional integration through IP cooperation and aims to upgrade national IP systems for creation, protection, utilization, administration, and enforcement to be in line with international best practices and standards and the strategic objectives of the ASEAN Intellectual Property Rights Action Plan 2016-2025. The guides were developed by Tilleke & Gibbins’ lawyers in cooperation with the IP offices of each participating country, and cover issues related to trademarks, industrial designs, and geographical indications. Each guide was produced in a compact leaflet form in English as well as the local language, and is considered an official publication of the respective national IP office. The guides can be accessed from the ARISE+ IPR site (under “Leaflets, brochures and booklets”), or by clicking on the links below: Cambodia: English | Khmer Indonesia: English | Bahasa Indonesia Thailand: English | Thai Vietnam: English | Vietnamese

As Vietnam continues to fight the latest wave of the Covid-19 pandemic with strict social distancing measures, the Intellectual Property Office of Vietnam (IP Office) has issued Notice No. 7581/TB-SHTT dated August 2, 2021 (Notice 7581), extending certain deadlines for IP applicants. The contents of Notice 7581 are similar to those found in Notice 5277 issued in March 2020 during the first wave of the pandemic. Specifically, Notice 7581 reads as follows: All procedures related to procedures to establish industrial property rights (priority claims, supplementation of documents, responses to the IP Office’s decisions/notifications, renewal and extension of the validity of protection titles, payment of fees and charges, and filing of appeal petitions) falling due during the period from June 30, 2021, to the end of August 31, 2021, will automatically be extended to the end of September 30, 2021. For other cases, if an applicant is still affected by the Covid-19 epidemic with regard to the implementation of its rights and obligations in the procedures for establishing rights to industrial property objects at the IP Office, such applicant may request [the IP Office] to apply the clauses on objective obstacles and force majeure as set out in Points 9.4 and 9.5 of Circular No. 01/2007/TT-BKHCN, as amended and supplemented by Circular No. 16/2016/TT-BKHCN. Observations on the Content of Notice 7581 As with last year’s Notice 5277, it is worth noting that the wording of Notice 7581 covers only the procedures to “establish industrial property rights,” rather than all aspects of industrial property rights. Further, it could be understood that it provides a closed list of industrial property procedures that can enjoy this grace period, and that the deadline extensions would apply only to the specific items listed. Thus, it is uncertain if the deadline extension to September 30, 2021,
