J Isern Patentes y Marcas holds its position across the board. The firm's strongest areas are arguably trade mark, copyright and domain names; however it has been growing its patent expertise and in 2010 hired a new head of biochemistry, Alely Gessa. Last year also saw the firm recruit transfer technology attorney Manuel Gerrera.
The firm has been busy of late tapping into work emanating from trade in counterfeit products and customs seizures. Through 2010 the firm was active on a variety of contentious cases. Lawyer Ignacio Valdelomar represented headphone manufacturer KOSS in an anti-counterfeiting dispute and successfully advised Philips on DVD infringement case. The firm advises a number of organisations with social aims including Médicos sin Frontera.
