Appeal No. 2006-2255 Application No. 10/183,994 cursor control mechanism also includes global controller 22 comprising a screen navigation ring 40 having a plurality of direction buttons 42. Id. at ll. 56-64. In the rejection of claims 1-32 under 35 U.S.C. § 103 as being unpatentable over Schein and APA, the examiner finds that Schein fails to disclose a tracking assembly for detecting movement of the housing relative to a support surface. However, such tracking assemblies were known in the prior art (e.g., APA). According to the rejection, it would have been obvious to include the tracking assembly in the Schein apparatus in view of APA and a teaching at column 7 of Schein. In another embodiment, computer system 62 [Fig. 3] may be combined with television system 60 to form a PCTV. In this embodiment, the computer will usually include a processor that may be used solely to run the program guide and associated software, or the processor may be configured to run other applications, such as word processing, graphics, or the like. The computer will usually be incorporated into the television set so that the television display can be used as both a television screen and a computer monitor. Usually, the PCTV will include a number of input devices, such as a keyboard, a mouse and a remote control device, similar to the one described above. However, these input devices may be combined into a single device that inputs commands with keys, a trackball, pointing device, scrolling mechanism, voice activation or a combination thereof. Schein col. 7, ll. 12-26 (emphasis added). Appellants, for their part, argue that the proposed combination would not have been obvious because the addition of a prior art tracking assembly to the Schein device would constitute redundancy. According to appellants, Schein already provides a complete system for controlling movement of a cursor. (Brief at 6.) -4-Page: Previous 1 2 3 4 5 6 7 8 NextLast modified: November 3, 2007
