‘Arntzen Grette’s IP team has been a breath of fresh air for us. As a fast-moving AI/edtech company, we don’t have time for legal memos that sit on a shelf—we need clear calls that help us ship with confidence. This team gets it. They translate tricky questions about data, AI outputs, trademarks, copyright, database rights, and open-source use into practical steps we can act on the same day. Compared with other firms we’ve used, they are faster to the point, more commercially minded, and consistently calibrated on risk: they lay out the options, explain the trade-offs, and let us choose the path that fits our roadmap.’
‘We value how senior lawyers stay engaged while associates keep momentum, and how smoothly they loop in privacy and tech specialists so nothing falls between the cracks. On the “how,” they’ve been refreshingly modern- clear scoping, tidy redlines, shared workspaces, and simple playbooks (like brand-clearance and OSS checklists) that our team can run with between matters. When enforcement is needed, they start pragmatic and escalate only when it truly protects value. In short, this is a business-first IP practice that safeguards our core assets without slowing us down—and that combination is rare.’
‘Tommy Dahlen is our main point of contact and the person who consistently turns complexity into momentum: he listens, frames decisions as clear options with trade-offs, and then helps us execute—whether that’s shaping IP clauses in a strategic partnership, aligning open-source use with our roadmap, or calibrating risk so we can ship on time. He’s calm under pressure, commercially sharp in negotiations, and unfailingly pragmatic; more than once, he has recut a sprawling redline into a crisp, win-win structure that both protects our core assets and keeps the deal moving.’

‘ I am very satisfied with how DLA Piper Norway has quickly understood the questions and complexities, and helped us to navigate issues. Our view is that the most complex issues are handled both by law, but also need an understanding of the consequences for our business. DLA understands both aspects.’
‘DLA Piper Norway AS has assisted with agreements (with all major Norwegian publishing houses), competition law matters towards the Norwegian competition authority (NCA), and the sale of a Norwegian daughter company (Infomedia Norge AS). DLA Piper has acted as lead counsel in all matters and across the Nordics. Matter sizes have been substantial.’
‘Professional, knowledgeable in all matters, easy to discuss and cooperate with. Strategic and creative in their solutions. In comparison with other law firms, they stand out.’
