IAM Patent 1000 – The world’s Leading Patent Professionals

IAM Patent 1000 – The World’s Leading Patent Professionals – is a guide that identifies the top patent professionals in key jurisdictions around the globe. Individuals qualify for a listing in the IAM Patent 1000 when they receive sufficient positive feedback from peers and clients with knowledge of their practice and the market within which they operate. IAM also also identifies the leading firms in the market – similarly listing them, where appropriate, in prosecution, transactions and litigation tables. In instances where certain individuals or firms attracts significantly greater positive feedback from clients and peers, they have been listed as “highly recommended”, to distinguish them from their “recommended” peers.

“Standing tall since 1975, Ström & Gulliksson runs a globally connected prosecution outfit that has become synonymous with quality. It collaborates extensively with the corporations it assists and manages an immense number of portfolios containing thousands of patent families. Its business model has caught the eye of a diverse clientele, including Ericsson, IKEA, Rolls-Royce and Spotify, to name a few. Leading lights Rikard RoosBjörn Andersson and Christian Arkelius garner warm plaudits from the market. “Service-minded and in tune with patrons’ needs, Roos is keen on providing support from ideation through to creation and his clever technical arguments are crucial to a successful outcome in litigation.” His shrewd counsel was sought out in invalidation proceedings on behalf of Sandoz. In the field of electronics, “Andersson is a fantastic and energetic attorney with a business mindset which culminates in superb, spot-on advice”. “Arkelius is remarkably resourceful and detail orientated in his approach to prosecution. In close alliance with each business, he establishes mutual venture goals and procures valuable IP assets that are enforceable on an international scale.” The firm recently welcomed the arrival of Peter Ekwall, a perceptive strategist who now heads up its Gothenburg operations.”

“From its headquarters in Malmo, Ström & Gulliksson plays a vital role in the prosecution and enforcement strategies of its diverse client base. “A proficient outfit experiencing considerable growth”, it is a prime choice for instructions across the contentious/non-contentious divide and a favourite among pharmaceutical powerhouses for its technical support in litigation. For these players, dedicated, proactive and creative attorney Rikard Roos “quickly identifies and understands the relevant issues of any case; he plays an instrumental and inventive role in any high-stakes litigation team”. Electronics and computer technology savant Björn Andersson boasts an unrivalled breadth of talent; “vastly experienced in proceedings before the EPO”, the able prosecutor is valued for his non-contentious strategy and has also contributed his expertise to six separate IP litigations over the last 12 months. “With a good eye for detail and incredible technical knowledge, Björn adds value through his pragmatic and accessible style.” Telecoms, media and technology expert “Christian Arkelius stands out from the crowd. Detailed and hands-on, he is the best kind of patent attorney and gets to grips with every aspect of an innovation. Top of the list when it comes to knowledge of European and Asian patent processes, he is also able to write US-style applications – a rare gift for attorneys outside of the United States”.”

His communication is always very clear, fast and productive. This, together with his broad technical knowledge and deep experience, makes him a very valuable partner.” Stockholm office chief Christian Arkelius “is efficient and meticulous. He is proactive, cost efficient, delivers on time and is street smart in an ever-evolving business environment”.

“Ström & Gulliksson has been sailing on calm seas since a 2011 management buy-out went down. The firm is adept at securing patent protection, but is also an astute player of the litigation game – uniting with sister set-up Advokatbyrån Gulliksson, it is a force to be reckoned with in the patent infringement stakes. Under the stewardship of Rikard Roos, the set has forged ahead. An accomplished sportsman, Roos knows what it takes to compete and win, and puts this knowledge to good use for clients. He is a master of the art of prosecution and a dab hand at EPO opposition and appeal proceedings. Also prominent is Björn Andersson, a perspicacious counsellor whose opinions on infringement matters carry great weight. While Roos concentrates on medical devices, pharmaceuticals and chemical engineering, Andersson focuses on everything high tech.”

IAM Strategy 300 – The world’s Leading IP Strategists

IAM Strategy 300 – The World’s Leading IP Strategists identifies the individuals who are leading the way in the development and implementation of strategies that maximise the value of IP portfolios. These Top IP strategists are primarily identified through confidential nominations. However, the IAM research process also involves face-to-face and telephone interviews, as well as email exchanges, with senior members of the global IP community. No one can qualify for a listing in the IAM Strategy 300 unless he or she is nominated by at least three people from outside his or her own organisation.
