Work Highlights

Advised a multinational pharmaceutical company for the launch of a breakthrough in Brazil. Viviane and her team developed strategies to guarantee that the competitor’s patent portfolio would not prove troublesome to the launch of the product.

Represented a company which develops Internet of Things (IoT) solutions to secure its patents and reverse a BRPTO’s decision nullifying the patent in a Post-Grant Review (PGR). Viviane and her team successfully attained a preliminary injunction to uphold the patent’s validity throughout the proceedings, and later successfully won the case on the merits, the patent, thus, being fully restored.

Representing a major agribusiness and food company in a lawsuit filed by a competitor seeking to analyze samples of our client’s trade-secret-protected products. An ex parte Court order was granted to seize the samples of the client’s products, but Viviane and her team successfully halted the examination of the samples until a method is established to determine the alleged infringement without disclosing our client’s confidential information. This matter remains ongoing.

Represented the world’s major producers of tires and associated services in an unfair competition case against a competitor. This competitor violated our client’s intellectual property rights, including trademarks, industrial designs, and patents. Over 10,000 infringing goods were seized. The defendant fought for over a year to recover the seized goods. However, their efforts were unsuccessful until a court-appointed expert conducted an on-site technical inspection. This inspection was strategically requested by our team and granted by the judge to preserve the evidence of infringement. The expert’s opinion was favorable to our client, and the case is currently progressing towards a settlement agreement.
