Legal 500 Editorial commentary
Testimonials
Collated independently by Legal 500 research team.
- '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.'
- 'The qualities we value most are their responsiveness, clarity, and steady judgment; they help us protect value without slowing us down, and that combination has earned our trust.'
- '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.'
