Office Action

§102 §103
Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Response to Arguments Applicant’s arguments with respect to claims 1-8 and 11-18 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention. Claims 1-2, 4, 6-7, 11-13, 15 and 17 and are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Zott et al., US 2009/0228919. Regarding claims 1 and 12, Zott discloses a screen projection method, applied to a screen projection device, comprising: Receiving, by the screen projection device, a screen projection request from a screen projection display device requesting to project a media file of the screen projection device onto the screen projection display device, wherein the screen projection request comprises an access address of a player page (paragraph 28 and 93-99); Generating, by the screen projection device, the player page for projecting the media file based on the access address, wherein a player is built in the player page, and wherein the media file in a preset format is stored by the screen projection device (paragraph 66); and Transmitting, through the player page to the screen projection display device, the media file in the preset format via a hypertext transfer protocol (figure 3, paragraph 34). Regarding claims 2 and 15, Zott discloses the method according to claim 1, before the transmitting the media file in the preset format via the hypertext transfer protocol, further comprising: reading or recording the media file (figure 4); and encapsulating the media file into the preset format, wherein the preset format comprises a Flash Video (FLV) format or a Transport Stream (TS) format (paragraph 34). Regarding claims 4 and 17, Zott discloses a screen projection method, applied to a screen projection display device, comprising: sending a screen projection request for requesting to project a media file of a screen projection device onto the screen projection display device, wherein the screen projection request comprises an access address of a player page (paragraph 28 and 93-99); loading the player page according to the access address, wherein a player is built in the player page, and a play address associated with the player is an address of the media file in a preset format stored by the screen projection device (paragraph 66); pulling the media file in the preset format from the play address in the screen projection device through the player page (paragraph 34); and playing the media file in the preset format (paragraph 34). Regarding claims 6 and 11, Zott discloses a screen projection device, comprising: a processing apparatus, and a memory storing a program that upon execution by the processing apparatus (figure 3) causes the processing apparatus to implement operations comprising: receiving, by the screen projection device, a screen projection request, from a screen projection display device requesting to project a media file of the screen projection device onto the screen projection display device, wherein the screen projection request comprises an access address of a player page (paragraph 28 and 93-99); generating, by the screen projection device, the player page for projecting the media file based on the access address, wherein a player is built in the player page, and wherein the media file in a preset format is stored by the screen projection device (paragraph 66); and transmitting, through the player page to the screen projection display device, the media file in the preset format via a hypertext transfer protocol (paragraph 34). Regarding claims 7 and 13, Zott discloses the device according to claim 6, the operations further comprising: reading or recording the media file (figure 4); and encapsulating the media file into the preset format, wherein the preset format comprises a Flash Video (FLV) format or a Transport Stream (TS) format (paragraph 34). Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claims 3, 5, 8, 14, 16 and 18 are rejected under 35 U.S.C. 103 as being unpatentable over the Zott in view of Yim et al., US 2014/0074924. Regarding claims 8 and 14, Zott discloses the device according to claim 6. Zott is silent about broadcasting the address of the media file in the preset format to at least one screen projection display device based on a Digital Living Network Alliance (DLNA) protocol or a Multicast Domain Name System (MDNS) protocol before receiving the screen projection request. In an analogous art, Yim discloses broadcasting the address of the media file in the preset format to at least one screen projection display device based on a Digital Living Network Alliance (DLNA) protocol or a Multicast Domain Name System (MDNS) protocol before receiving the screen projection request (paragraph 53 and 74). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Zott’s device with the teachings of Yim. The motivation would have been to have the address ready when needed for the benefit of providing quality of service. Claims 3, 5, 16 and 18 are rejected on the same grounds as claim 8. Conclusion THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
