Important Legal Qualification

Statement of scope

This analysis identifies publicly disclosed technical similarities and differences for strategic patent-positioning purposes. It does not constitute an allegation or conclusion of infringement. Claim construction, prosecution history, issued claims and implementation-specific facts require review by qualified U.S. patent counsel.

Scores

How the numbers must be read

Every score displayed on this site is labelled: Preliminary Patent-Position Investigation Score – not a legal conclusion. The five scores are never combined into a probability of infringement.

Evidence categories

Five separations are mandatory

What is publicly disclosed
What is inferred
What has not been identified publicly
What the Kahler patent adds
What requires internal legal / technical verification

Claim analysis

All limitations matter

Patent infringement analysis generally requires every limitation of a relevant claim to be established, directly or under applicable legal doctrine. Nothing on this site should be read as suggesting that satisfying several limitations establishes satisfaction of all limitations.
