`22 ....” Id., 10:34-37.
`
`Burroughs discloses a “dose dial sleeve” in the form of dial mechanism 34.
`
`EX1013, 7:31-32, FIG. 2; EX1011, ¶¶162-65. The dial mechanism is positioned
`
`within housing 22, and includes, on its outer surface, threads 110, 112. EX1013,
`
`7:65-67, 8:33-36, FIGS. 1-2, 6-9; EX1011, ¶166. Threads 110, 112 are configured
`
`to releasably engage a helical spiral groove 158 provided on an inner surface of the
`
`housing 22. EX1013, 8:62-9:1, FIGS. 1, 3, 5-9; EX1011, ¶167.
`
`Threads 110, 112 are rib-like structures that fit into and move within helical
`
`spiral groove 158 of the housing parts 24, 26 to allow the dial mechanism to rotate
`
`and move axially away from the needle-end of the housing during the dose-setting
`
`phase. EX1013, FIGS. 6-9; EX1011, ¶164. As Mr. Leinsing explains, in order to
`
`properly engage with the helical spiral groove 158 for rotation, the threads 110,
`
`112 also must be positioned helically relative to one another, forming a
`
`discontinuous helical rib corresponding to the housing’s helical groove. EX1011,
`
`¶165; cf. EX1002, 3:42-44 (describing threads may include part threads). FIGS. 1
`
`and 7 best show the helical positioning of the threads 110, 112. EX1011, ¶165.
`
`Thus, Burroughs discloses that the dial mechanism 34 includes a “helical rib,” in
`
`the form of threads 110, 112, along its outer surface that engages with a threading
`
`on the housing 22. EX1011, ¶166.
