Lindahl has undoubtedly become one of Sweden's leading IP firms since its merger in 2009 with IP boutique RydinCarlsten. According to one competitor, "the staff there have a good standard of work and are rated very highly in Sweden as a whole". Clients say the firm is "experienced and has a great knowledge regarding IP", and is "very service oriented".
The firm handled one of the biggest cases of the year, which saw partner and head of IP Håkan Borgenhäll represent Merck & Co in the Gentili District Court of Stockholm over the revocation of a patent and infringement related to one of Merck's former bestselling pharmaceuticals Fosamax. Another big case saw partner Ulf Dahlgren advise Casco Adhesive on a successful patent infringement claim against Norwegian company Dynea. In 2011 Borgenhäll and Katarina Strömholm were also advising Swedish Match North Europe on the shape of its circular 'snuss' box as a 3D trade mark.
On the trade mark and design side in 2010, Henrik Wistam advised BMW on Community trade mark infringements and Svensk Mjölk on regulations regarding definitions and designations for foodstuffs. Lindahl also manages H&M's global trade mark portfolio as well as co-ordinating its global IP litigation, and handled trade mark portfolios for Viking Line and Transatlantic, two leading shipping companies. In copyright the firm acts for collecting societies, copyright organisations and authors as well as a TV channel. "Jonas Westerberg makes a very good impression," comments one client.
In 2010 the firm hired four staff at associate level.
