Since its founding in 1916 in Santiago, Estudio Villaseca's IP practice has succeeded in building a reputation as one of the leaders in this practice area. The firm's IP group, comprising 16 professionals and patent/trade mark agents, is particularly known for its patent work regarding plant varieties. Peers also refer to the firm's "strong litigation group". The firm does both patent and trade mark work for F Hoffmann-LaRoche, Colgate-Palmolive, Bulgari and GE.
During 2012, the firm conducted a successful enforcement campaign, initiating border measures and criminal actions on behalf of Sanrio, Apple, Longines/Tissot and Bulgari. The firm's actions resulted in the seizure and destruction of thousands of counterfeit products over a five-month period.
In another notable case, Estudio Villaseca filed a cancellation action in August 2012 on behalf of its client, local pharmaceutical company Salcobrand. The action seeks to cancel the registration of the generic drug Resveratrol, on the grounds that a generic name cannot be owned by a specific person or entity but must remain in the public domain. The decision is pending.
