Begin with a question
Signal is our collection of public articles and media. It connects familiar technology with a closer reading of patents and evidence. You can read and share it without an account.
Inspect a Baseline
A Baseline is a published analysis with a fixed version. Read the exact claim wording, select a Unit, and follow the associated passages to the source. The evidence and its limitations stay together.
Previews are public. A verified personal or work email gives access to all published full Baselines when registration is open. There is no payment flow in this Beta.
Keep judgment with the reader
The site supports patent research, litigation preparation, and due diligence. It does not provide a legal opinion or decide infringement, validity, or a dispute. Check the source and the scope of each analysis before relying on it.
A project in progress
QualiLens is an independent project by Felicia Yang. It is at an early stage, and feedback on the reading experience is welcome.
