For a search, we agree the claims or technical question, dates, jurisdictions and the evidence you need. You receive a search log, source passages and a comparison chart.
We agree the work, deliverables, fees and outside costs before starting. Choose a focused project or continued help around your needs.
Start with a clear need. A retainer supports continued implementation; its scope, review schedule and terms are agreed individually.
We agree on the question, the technical field, the relevant dates and countries, and when to conclude the search. I put these limits in writing before starting.
I search by subject and by words in the documents, and check related patents. I record the searches and selection decisions so another researcher can review the work.
You receive the references and a table comparing the relevant passages with the patent claims. I include the source for each passage and explain what the search did not find.
I’m Zachary Wolfe, a physicist and patent analyst. I have spent years reading and classifying patents in the electrical and physics arts, and I do the searching myself.
You keep control of your accounts and data. We agree on payment and any ongoing support before work starts.
No. This is search and analysis work built on public patent data: references, claim charts, classification and landscapes. It is not legal advice and not an opinion on whether a patent is valid, invalid or infringed.
