Typical Questions Addressed
- Does a prior-art reference (patent, publication, product, or standard draft) disclose each limitation of the challenged claims?
- Would a person of ordinary skill have been motivated to combine the asserted references with a reasonable expectation of success?
- What was the state of the art in Wi-Fi, cellular, Bluetooth, or RFID at the priority date?
- How should disputed claim terms be construed in view of the specification and the knowledge of a POSITA?
- Is an IEEE 802.11 draft, 3GPP TDoc, or Bluetooth specification a printed publication, and what does it teach?
