Before DYK, REYNA, and HUGHES, Circuit Judges. HUGHES, Circuit Judge. This is a patent case involving garage door and gate operator systems. The Chamberlain Group, Inc. appeals the final written decision of the Patent Trial and Appeal Board in an inter partes review of claims 18–25 of U.S. Pa- tent No. 7,196,611, which found all challenged claims an- ticipated. See One World Techs., Inc. v. Chamberlain Group, Inc., No. IPR2017-00214 (P.T.A.B. May 15, 2018). Because the Board’s anticipation findings are supported by substantial evidence, we affirm. I A Chamberlain owns the ’611 patent entitled “Barrier Movement Operator Human Interface Method and Appa- ratus.” The ’611 patent is directed to improved methods of human interaction with “barrier movement operators,” such as garage door operator systems. ’611 patent, col. 1 ll. 6–14. The system includes “a motor for moving a barrier between open and closed positions” and a controller that selectively supplies power to the motor. Id. col. 1 ll. 9–12. The controller “includes a programmed microprocessor, [which] responds to user input signals” from a wall control unit and a radio transmitter. Id. col. 1 ll. 64–66. The con- troller also connects “to a plurality of input/output devices” such as a rotary switch and indicator LEDs that “advise a user of the status of particular controller functions.” Id. col. 2 ll. 41–42, 52–53. Claims 18–25 of the ’611 patent are directed to an “in- teractive learn mode” that “guide[s] a user through instal- lation and learn mode actions.” Id. col. 4 ll. 13–14. During THE CHAMBERLAIN GROUP, INC. v. ONE WORLD 3 TECHNOLOGIES, INC.

the learn mode, the controller “determines the user activi- ties or steps needed during the learn process” and guides the user through those steps by flashing the indicator LEDs. Id. col 4 ll. 17–19. The ’611 specification describes the example of using the learn mode to set the garage door operator’s “max run timer.” Id. col. 4 l. 45. The max run timer is the amount of time for the door to move between its open and closed lim- its, plus five to ten seconds. The system uses the timer to determine whether the door has been moving for too long without reaching its final open or closed position. The ’611 patent teaches the following steps for setting the max run timer during the learn mode. First, the user presses a button on the controller to enter learn mode. Next, the controller identifies the proper beginning status for the door and the steps the user must complete to set the timer. Finally, the controller guides the user through the identified steps by flashing the appropriate indicator LED for each step. For example, if the step requires the user to open the door, the controller will flash the open limit LED. Once the user completes all the steps, the controller counts the time for the door to travel from its closed limit to its open limit, adds five to ten seconds, and records that value as the max run timer. Independent claim 18, reproduced below, is illustrative of the challenged claims: 18. A method of assisting in the installation and maintenance of a barrier movement operator in- cluding a controller, comprising: activating a learn mode activity of the con- troller of the barrier movement operator which learning mode requires pre-deter- mined activities by a user; 4 THE CHAMBERLAIN GROUP, INC. v. ONE WORLD TECHNOLOGIES, INC.

first identifying by the controller the pre- sent status of the barrier movement opera- tor; second identifying by the controller, the ac- tivities to be completed by a user of the bar- rier movement operator; and responsive to the first and second identify- ing steps transmitting guidance signals to an annunciating unit for guidance of the user. ’611 patent, col. 6 ll. 25–38. B One World Technologies, Inc. petitioned for IPR of claims 18–25 of the ’611 patent. One World’s petition as- serted that claims 18–25 are anticipated under 35 U.S.C. § 102(b) by U.S. Patent No. 4,638,433 (Schindler), and that claims 23 and 24 are obvious under 35 U.S.C. § 103(a) over the combination of Schindler and an owner’s manual for an industrial duty door operator (LiftMaster). 1 The Board in- stituted review on all challenged claims on both asserted grounds. Schindler is a U.S. Patent directed to a garage door op- erator system. It teaches a mode that allows the user to program the upper and lower limits for the garage door’s movement. In this mode, Schindler’s controller flashes an indicator LED to communicate which limit is being pro- grammed to the user. Depending on which LED flashes, the user must press and hold the corresponding switch— “door open” for the upper limit or “door close” for the lower limit—until the door reaches its limit position. To set the

second limit, the user must press a control switch button. The controller then flashes the appropriate indicator LED for the remaining limit, instructing the user to press and hold the corresponding switch until the door reaches its limit position. Finally, the controller stores the door’s max- imum upper and minimum lower positions as the upper and lower limits. One World’s petition argued that Schindler’s program mode teaches every limitation of claims 18–25 of the ’611 patent. It argued that claim 18’s second identifying step, that the controller identify “activities to be completed by a user,” ’611 patent, col. 6 ll. 33–34, should be construed to mean “the controller establishing which of the pre-deter- mined activities a user must complete,” J.A. 86. The peti- tion relied on Schindler’s disclosure that the controller determines which limit is being programmed during the program mode to teach that limitation. In its patent owner response, Chamberlain argued that the second identifying step should be construed to require identifying multiple activities. According to Chamberlain, “Schindler clearly establishes that its controller identifies a single activity; it either sets the ‘up’ limit, or it sets the ‘down’ limit.” J.A. 1200 (emphasis omitted). One World’s reply asserted that “Schindler unambigu- ously teaches that multiple limit-setting activities are com- pleted by a user during the program/ learn mode.” J.A. 1467–68. It claimed that “when Schindler’s controller makes a decision as to whether a user should start setting an up limit or a down limit, it necessarily identifies multi- ple activities.” J.A. 1471–72.
