What customers say

Based on genuine customer reviews

Trademark registration and intellectual property management dominate the feedback for this Sydney practice, with practitioner Olaf Kretzschmar named repeatedly as the central figure. More than one customer describes his guidance through the application process as clear and thorough, noting that he explains each stage in straightforward terms and keeps clients informed while applications are pending. Something that features in review after review is the speed with which queries and procedural issues are resolved, including early approval of a trademark certificate and the handling of revisions and associated paperwork.

Reviewers repeatedly mention his availability from the first phone call and the value of an initial consultation, with one client contrasting previous self-managed filings against the expert support received. Beyond trademark work, feedback covers contractual agreements negotiated for a volunteer board role, involving cross-border considerations, and ongoing management of existing trademark portfolios, including renewals and deadlines. The practice is described as professional, knowledgeable and proactive in communication, with clients expressing confidence that their intellectual property matters are being managed attentively and that they can concentrate on running their businesses while the administrative complexities are handled.

Olaf and his team at One IP are the best in their specialism. Olaf provides expert advice on Trade Mark law. He deals in specifics, details, and the correct classifications, to ensure a Trade Mark is precisely correct. From the initial enquiry and application process through to filing, and ultimately Registration, Olaf maintains constant communication. I could not recommend Olaf and One IP more highly.

We've had the pleasure of working with Olaf for our trademark management, and the experience has been nothing short of exceptional. He is highly knowledgeable, professional, and incredibly thorough in his approach. We particularly appreciate Olaf's proactive communication, he ensures we're always on top of deadlines, renewals. It's been a great reassurance knowing our trademarks are in such capable hands.
