Represented an important European pharmaceutical producer of several drugs for dermatological diseases. The Brazilian FDA Agency (ANVISA) denied the prior consent of one of the firm’s client’s patent application based on the understanding that said invention did not comply with patentability requirements. In order to challenge ANVISA’s decision the firm filed before the Federal Courts of Brasília a writ arguing that the Brazilian Patent and Trademark Office is the sole authority entitled to assess patentability requirements. The firm was very successful in obtaining an ex parte injunction that ordered ANVISA to annul its previous decision and to render a new one in 30 days, this time limited to public health issues.

Represented a multinational beverage corporation owner of one of the world’s strongest and most recognised trademark and trade dress in an infringement lawsuit involving the imitation of the client’s label and the possible confusion and/or undue association of the products, against a solid manufacturer of soft drinks headquartered in the city of Manaus (Amazonia). The firm’s office was able to achieve a successful result, having been granted an ex parte injunction to, among other things, prevent the defendant from using the trade dress under dispute.

Represented a huge Brazilian jewellery store chain, in an infringement lawsuit filed by the heirs of Paul Landowski, a French-Polish artist, against the firm’s client, seeking damages for the alleged unauthorised sale of pendants reproducing the Christ, the Redeemer one of Rio de Janeiro’s landmarks, and claiming that Landowski was the author, and sole owner of the copyright of such work. With evidence, gathered by the firm, that the Christ, the Redeemer was a work made for hire, and idealised by the Archdiocese of Rio de Janeiro as a celebration of the 100 years of Brazilian Independence in 1922, the Court decided in the client’s favour, stating that the sole owner of the copyright over Christ, the Redeemer is the Archdiocese of Rio de Janeiro.

Represented one of the global leaders in products and solutions for improving foundry performance and the quality of castings, in an administrative proceeding before the Brazilian Patent and Trademark Office. The client’s royalty-bearing trademark license agreement with its subsidiary providing for the payment of 1% of royalties on the sales of products covered by licensed trademarks was rejected by the BPTO, under the allegation that it was not possible to authorise royalty payments in this situation, when the licensed trademarks were being used by the subsidiary prior to 31st December 1991. In the firm’s appeal to the BPTO’s attorney general, the firm called his attention to the accurate interpretation of article 50 and its sole paragraph of Law 8383/91, according to which the remittance and deductibility of trademark royalties between a mother company and its subsidiary become licit and possible, provided the trademark royalties are duly established through a trademark license agreement executed as from 1st January 1992. The attorney general accepted the firm’s appeal and reverted the previous decision.
