IP Holdings, LLC is the Patent Owner and the real party in interest (App. Br. 1). 2 Issued February 7, 1995, to Gilbert M. Dinkins. Appeal 2011-008301 Reexamination Control No. 90/010,383 United States Patent 5,388,101 2 STATEMENT OF THE CASE3 This proceeding arose from a request for ex parte reexamination filed by Robert Greene Sterne and Jonathan Tuminaro on behalf of an unknown third party requester on January 9, 2009 of United States Patent 5,388,101 (the '101 Patent), based on U.S. Patent Application 07/966,414, filed October 26, 1992. The '101 Patent was asserted in cases styled EON Corp. IP Holdings, LLC v. Sensus USA Inc. et al., CA No. 6:09-cv-00116 (E.D. Tex. 2009)(hereinafter “Sensus case”); and EON Corp. IP Holdings, LLC v. Verizon Clinton Center Drive Corp. et al., Civil Action No. 6:08-cv-00385 (E.D. Tex. 2008)(hereinafter “Verizon case”) (App. Br. 22), where the former case is apparently ongoing and the latter case is settled. The '101 Patent was also asserted in, at least, cases styled Verizon Clinton Center Drive Corp. v. EON Corp., CA No. 1:09-cv-0823 (D. Del. 2009); and Verizon Clinton Center Drive Corp. v. EON Corp., CA No. 1:10-cv-0179 (D. Del. 2010), where the Office was not notified of those proceedings. Appellant is reminded on their ongoing duty to keep the Office abreast of related proceedings. We heard oral arguments from a representative of Appellant on August 3, 2011, a transcript4 of which is part of the record. 3 Our decision will make reference to the Appellant’s Appeal Brief (“App. Br.,” filed September 7, 2010), Supplemental Appeal Brief (“Supp. Br.,” filed September 13, 2010), and Reply Brief (“Reply Br.,” filed February 14, 2010), and the Examiner’s Answer (“Ans.,” mailed December 14, 2011). Appeal 2011-008301 Reexamination Control No. 90/010,383 United States Patent 5,388,101 3 CLAIMED INVENTION Appellant’s invention relates to an interactive two-way data service network for conveying synchronously timed digital messages point to point throughout a network (col. 1, ll. 8-10). Independent claims 19 and 20 are the only claims rejected in the instant reexamination: 19. An interactive video data system comprising: subscribers with portable subscriber units and facilities for communicating from the subscriber units when moved through different geographic zones, and a set of subscriber units limited to digital processing facilities comprising digital transducers and means for transmitting digital data derived by said transducers. 20. An interactive video data system comprising: subscribers with portable subscriber units and facilities for communicating from the subscriber units when moved through different geographic zones, a base station of defined geographic area for serving a set of said subscriber units, said area is subdivided into a plurality of zones, and receive only stations located in said zones for reception of transmissions from subscriber units located in the respective zones, and facilities in said base station and subscriber units for handing off communications between zones when communicated signals deteriorate below a given threshold. 4 Record of Oral Hearing (hereinafter Oral Hr’g Tr.) Appeal 2011-008301 Reexamination Control No. 90/010,383 United States Patent 5,388,101 4 REJECTION Based on the rejection maintained in the Answer5, the prior art references relied upon by the Examiner in rejecting the claims are: Cunningham 4,144,496 Mar. 13, 1979 Martinez 4,928,177 May 22, 1990 The Examiner rejected the claims on the following basis, which was maintained in the Answer: Claims 19 and 20 under 35 U.S.C. § 103(a) as being unpatentable over Martinez and Cunningham (Ans. 5). Appellant relies upon the following evidence in rebuttal to the Examiner’s rejections: Declaration of Dr. Jay Kesan, dated October 7, 2009, (App. Br., Evidence Appx., Exhibit 2).

Order, dated May 17, 2010 from the Verizon case (Supp. Br., Evidence Appx., Exhibit 5). Memorandum Opinion & Order, dated August 11, 2010 from the Sensus case (Supp. Br., Evidence Appx., Exhibit 6). 5 In the Final Office Action, the Examiner also rejected the claims in additional rejections, which were subsequently withdrawn in the Answer (Ans. 3-4). Appeal 2011-008301 Reexamination Control No. 90/010,383 United States Patent 5,388,101 5 ISSUE Appellant raises numerous arguments as to whether Martinez and Cunningham render the instant claims obvious (App. Br. 9-15; Reply Br. 2- 12), some of which we discuss below. We have considered in this decision only those arguments that Appellant actually raised in the Briefs. Arguments which Appellant could have made but chose not to make in the Briefs are deemed to be waived. See 37 C.F.R. § 41.37(c)(1)(vii). The issue arising from the respective positions of Appellant and the Examiner is: Did the Examiner err in finding that claims 19 and 20 were rendered obvious over Martinez and Cunningham under 35 U.S.C. § 103? FINDINGS OF FACT 1. The '101 Patent discloses an interactive two-way data service network for conveying synchronously timed digital messages point to point throughout the network (col. 1, ll. 8-10). 2. The Specification of the '101 Patent provides that a set of local remote stationary receivers (20A-20N) are positioned each into locations within cell areas (22A-22X), to serve mobile units (4, 4', 4'', 4'''), with each local remote stationary receiver connected to the base station repeater (3) to provide interactive video a reduced transmission power levels (col. 5, l. 54 – col. 6, l. 4; Fig. 2). 3. The Specification of the '101 Patent provides that the software control data processor (54) performs a set-up algorithm to establish Appeal 2011-008301 Reexamination Control No. 90/010,383 United States Patent 5,388,101 6 communications between the mobile units (4, 4', 4'', 4'''), the local base station repeater (3), and the local remote stationary receivers (20A-20N) (col. 8, ll. 16-62; col. 9, ll. 14-25; Figs. 2, 6B, 9A). 4. In the '101 Patent, the setup procedure is important for hand-off of the portable unit from one site to another as fringe areas are encountered (col. 8, ll. 63-67). The signal strength measurement serves as a criterion for hand-off, with the cell directing the subscriber into a set-up routine when signals fall below a threshold (col. 9, ll. 7-10). 5. Martinez is directed to two-way data broadcast networks utilizing a conventional broadcast signal and a narrow band return link communication (Abs.). The network is also applicable to mobile terminals (54), where those terminals communicate in range of a radio net central receiver (28) (col. 3, 53-58, col. 6, ll. 59-64; Fig. 1). 6. Cunningham is directed to a mobile communication system which allows for communication with multiple mobile stations (160) in sectionalized geographical service areas, or sectors (A1-A3, B1- B3) (Abs.; Fig. 2). When a mobile station passes from one sector to another, and suffers a loss of communication, and the communication must be reestablished in the new sector (col. 24, ll. 44-48). After it has been determined that the mobile unit is moving into a particular sector, a channel is assigned to the Appeal 2011-008301 Reexamination Control No. 90/010,383 United States Patent 5,388,101 7 established call in that sector, on the same or different channel (col. 26, ll. 14-20, 31-34). PRINCIPLES OF LAW “To render a later invention unpatentable for obviousness, the prior art must enable a person of ordinary skill in the field to make and use the later invention.” In re Kumar, 418 F.3d 1361, 1369 (Fed. Cir. 2005) (citing Beckman Inst., Inc., v. LKB Produkter AB, 892 F.2d 1547, 1551 (Fed. Cir. 1989) and In re Payne, 606 F.2d 303, 314-15 (CCPA 1979)). “Section 103 forbids issuance of a patent when ‘the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains.’” KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). ANALYSIS While the Examiner acknowledges the Supplemental Appeal Brief (Ans. 2), the Examiner does not appear to address the content therein, nor some of the specific arguments in the Appeal Brief. Appellant has argued that the “facilities for” limitations in claims 19 and 20 should be interpreted as means-plus-function limitations (Supp. Br. 8). Appellant also cited the claim construction of those limitations by the District Court, which found that “the use of ‘facilities’ here is inadequate to connote structure capable of Appeal 2011-008301 Reexamination Control No. 90/010,383 United States Patent 5,388,101 8 performing the claim function” (Supp. Br. 6), and argues that we should treat those limitations as means-plus-function limitations (App. Br. 13-14; Reply Br. 11-12). We agree. “[C]laim elements without express step-plus-function language may nevertheless fall within 112 6 if they merely claim the underlying function without recitation of acts for performing that function.” Seal-Flex, Inc. v. Athletic Track and Court Constr., 172 F.3d 836, 850 (Fed. Cir. 1999) (Radar, J., concurring). We find that the claims limitations reciting “facilities for” in claims 19 and 20 recite functions without reciting acts or structure for performing those functions. We acknowledge that M.P.E.P. § 2181 relieves the Examiner of the duty of pronouncing that § 112, sixth paragraph, has not been invoked; however, we find it incumbent on the Examiner to respond to the arguments recited in the Briefs. To the extent that the Examiner responds to arguments in the Appeal Brief, the Examiner finds Appellant’s interpretation of the “facilities for” limitation to be unduly narrow, and that interpreting those limitations to involve set-up and response associated with a broadcast and acknowledge mechanism “is not required to reasonably interpret the claims” (Ans. 8). However, as we find those limitations to be means-plus-function limitations, that is exactly what we must do, as discussed below. With respect to “facilities for communicating from the subscriber units when moved through different geographic zones,” from claim 19, we find that the corresponding structure is the mobile units, including software which provides a set-up algorithm as disclosed in Fig. 6B (FF 3-4). With Appeal 2011-008301 Reexamination Control No. 90/010,383 United States Patent 5,388,101 9 respect to “facilities in said base station and subscriber units for handing off communications between zones when communicated signals deteriorate below a given threshold,” from claim 20, we find that the corresponding structures are the local base station repeater and the mobile units, including software which allows for hand-off based on the criterion of signal strength and which provides a set-up algorithm as disclosed in Fig. 6B (FF 3-4). Appellant has also admitted that the “facilities for” limitations in claims 19 and 20 require a “setup and response sequence associated with a broadcast and acknowledge mechanism,” and that the combination of Martinez and Cunningham would have to teach or suggest such a limitation to render the claims obvious (Oral Hr’g Tr. 5-6). We do not find that the combination, as asserted in the rejection, does so. As Appellant argues, Martinez does not disclose mobile subscriber units which communicate in different zones or which provide for communication when passing between zones (App. Br. 12, FF 5). Cunningham provides for zones and mobile units passing between zones (FF 6), but does not disclose a set-up and response from the mobile units when a changeover occurs. Instead, Cunningham provides that when a sector change occurs, the call is reestablished without subscriber intervention, and a central control unit tunes the moved mobile unit to the same or different channel within the new sector (id.). As such, we agree with Appellant that “[b]oth Martinez and Cunningham fail to suggest any type of set-up and response sequence or associated broadcast and acknowledge mechanism” Appeal 2011-008301 Reexamination Control No. 90/010,383 United States Patent 5,388,101 10 (App. Br. 13), and cannot teach or suggest all of the elements of claims 19 and 20. CONCLUSION We conclude that the Examiner erred in finding that claims 19 and 20 were rendered obvious over Martinez and Cunningham under 35 U.S.C. § 103. DECISION We reverse the Examiner’s decision to reject claims 19 and20. REVERSED ack cc: FOR PATENT OWNER: DAFFER MCDANIEL LLP P.O.
