Formal Software IP Opinion Needed

I need a concise, written legal opinion that maps out every layer of intellectual property bound up in our proprietary software platform. Because we currently have no protections in place, I am looking for an Intellectual Property Lawyer who can start from a clean slate and give me a clear, actionable roadmap. My priority is to understand exactly what we own—the architecture and functionality, the underlying data structures and other proprietary elements, and the overall methodology that ties it all together. From there I want to see how each component can be ring-fenced through copyright, trade-mark strategy, patent possibilities (where truly novel), confidentiality measures and trade-secret protocols. The opinion must also dissect ownership questions that may arise from our work with an external development partner, highlight any third-party rights or licence conflicts that could hamper future commercialisation, and flag broader IP risks before they become issues. Deliverables • A formal legal opinion (PDF and editable format) covering: 1. Identification of protectable IP within the software 2. Recommended protection mechanisms for each element 3. Analysis of current and future ownership, including external developer contributions 4. Assessment of third-party or open-source risks and licensing impacts 5. Forward-looking recommendations to maintain and expand protection as the business scales Please ground your advice in the relevant jurisdiction(s) and cite any statutes or case law that materially supports your conclusions. A brief outline of your experience drafting software-focused IP opinions would be appreciated, along with an estimated timeline to deliver the report.
