In re Chatani: order of steps in a method claim

The CAFC addressed claim construction issues in In re Chatani, which claims were directed to a method for managing participants in an online session of a multi-user application.

For giving claims their "broadest reasonable interpretation," the CAFC cited In re Hyatt, 211 F.3d 1367, 1372 (CAFC 2000). In re Morris, 127 F.3d 1048 was also cited.

Although Chatani argued the claim steps had to be performed in the order recited, the CAFC found the claim language on its face did not require sequential performance.
