As of today, all claims of US9736618 remain untested by AIA trial proceedings. This means there are no canceled claims, no sustained claims, and no estoppel implications from prior PTAB decisions for any potential petitioner. The entire patent, with all its claims, is still open for challenge on any available statutory grounds, such as novelty (§ 102) or obviousness (§ 103). The absence of PTAB activity could indicate that the patent has not been extensively asserted or that previous assertions did not lead to such challenges.
Recommended next steps
If you are a defendant facing an assertion of US9736618, the absence of PTAB activity means that all claims are currently presumed valid.
