Patent Bear

Patent Bear answers questions about specific US and European patents, publications and applications, and finds patents and prior art by technology, owner, inventor or classification. It reads the claims and full text with column-and-line citations, the prosecution history and examiner office actions, assignments and chain of title, citations and families, FDA Orange Book listings, term and expiration, and the litigation and PTAB record: US court decisions and the Board's institution, final written, rehearing and Director review decisions in IPR, PGR and CBM trials. Use it whenever a patent number, a patentee, a patent-law issue or a named patent case comes up. Save authorized work to the connected Patent Bear Library.
