Appeal 2020-004992 Application 15/276,832 2 STATEMENT OF THE CASE The claimed systems and methods relate to “providing an alert to a driver of a vehicle, when the closest vehicle-in-front decelerates and the distance to the closest vehicle-in-front decreases.” Spec. ¶ 14. Appeal Br. 2. CLAIMED SUBJECT MATTER Independent claim 1, reproduced below with supplementary labels added in brackets, is illustrative. 1. A method for providing an alert to a driver of a host vehicle, the method comprising: (a) receiving, from a vehicle-to-vehicle communication, [(i)] deceleration information of a vehicle-in-front of the host vehicle, [(ii)] wherein the vehicle-in-front is located in a same lane of a road as the host vehicle and [(iii)] the deceleration information includes a brake message indicating that the vehicle- in-front is performing a braking function; (b) detecting a decrease in distance to a closest vehicle-in- front of the host vehicle by a vehicle sensor system in the host vehicle, wherein the closest vehicle-in-front is located in the same lane of the road as the host vehicle; and (c) issuing an alert to the driver of the host vehicle only in response to both (a) and (b) occurring simultaneously.

We review the appealed rejections for error based upon the issues identified by Appellant, and in light of the contentions and evidence produced thereon. Ex parte Frye, 94 USPQ2d 1072, 1075 (BPAI 2010) (precedential). The Examiner and Appellant focus their findings and contentions on claim 1 (see Appeal Br. 7–15; Ans. 3–11); so we do as well. Arguments not made are forfeited.4 Unless otherwise indicated, we adopt the Examiner’s findings in the Final Office Action, Advisory Action, and the Answer as our own and add any additional findings of fact for emphasis. We address the rejections below. ANALYSIS The Examiner finds Iwasaki’s disclosure of a vehicular peripheral surveillance device that includes lane and obstacle recognition sensors teaches or suggests many of the claim limitations, including those recited by claim 1’s claim elements (a)(i), (a)(ii), and (b). Final Act. 2–4 (citing 4 See In re Google Tech. Holdings LLC, 980 F.3d 858, 863 (Fed. Cir. 2020) (“We interpret the Patent Office to be arguing that Google’s failure to raise its lexicography arguments, inadvertent or not, compels a finding of forfeiture.”); 37 C.F.R. § 41.37(c)(1)(iv) (2019) (“Except as provided for in §§ 41.41, 41.47 and 41.52, any arguments or authorities not included in the appeal brief will be refused consideration by the Board for purposes of the present appeal.”). Appeal 2020-004992 Application 15/276,832 5 Iwasaki ¶¶ 21, 22, 45–61, 63–64, 66–67, 72, 78–79, 83, 85, 87–89; Figs. 1, 2, 4, 11, 13). Recognizing that Iwasaki “do[es] not explicitly teach [] the deceleration information includes a brake message indicating that the vehicle-in-front is performing a braking function,” (claim element (a)(iii)) the Examiner applies Tengler’s disclosure of a forward vehicle braking warning system for teaching or suggesting the noted deficiency. Id. at 4–6 (citing Tengler ¶¶ 11, 27–36, 54–57; Figs. 2, 5–12). The Examiner finds the combination of lwassaki and Tengler teaches [a] warning component to alert the driver [of an] imminent danger [ahead] either alone or in concert with [an]other warning signal . . . but they do not explicitly teach . . . (c) issuing an alert to the driver of the host vehicle only in response to both (a) and (b) occurring simultaneously. Final Act. 6 (citations omitted). To remedy the deficiency of the combination to teach claim element (c), the Examiner applies Avery’s disclosure of a driver interface unit that provides vehicle condition information including alerts and warnings based on various combinations of conditions. Id. at 7. In particular, the Examiner directs attention to Avery’s table 1 describing a warning indicator activated upon detection of a target that is (1) in the same lane as the host vehicle, (2) slowing down, and (3) within a predetermined threshold distance of the host vehicle. Id. Further, the Examiner finds that a person of ordinary skill in the relevant art would have had reason to combine the teachings of Iwasaki with those of Tengler and Avery to achieve the limitations of claim 1. Id. at 6, 7. Appellant contends the Examiner errs in rejecting claim 1, arguing as follows: 1. None of the applied references teach or suggest claim element (c) requiring an alert be issued only in response to both conditions (a) Appeal 2020-004992 Application 15/276,832 6 (receipt of a braking message from a vehicle-in-front) and (b) (a decreasing distance from a closest vehicle-in-front) (Appeal Br. 7– 12); 2. Iwasaki’s disclosure of detecting a deceleration of a closest vehicle-in-front of a host vehicle fails to teach decreasing a distance between the two vehicles (id. at 10–11); and 3. “[T]he Examiner’s proffered motivation fails to articulate any reason why one of ordinary skill would combine those references in the fashion recited in the Applicant’s claimed invention” (id. at 12–13). We address Appellant’s contentions of error as follows. 1. Issuing an Alert Only in Response to Both (a) and (b) (Claim element c) Appellant contends, rather than issuing an alert only when detecting both braking and a decreasing distance from a vehicle ahead, the asserted combination of prior art teachings would issue an alert when either condition occurs. Appellant argues as follows: In any such combination, according to the teaching of Tengler, the resulting system would issue an alert to a host vehicle driver whenever (i.e., every time) condition (a) occurred -- even in the absence of condition (b) occurring. Similarly, in any such combination, according to the teaching of Avery, the resulting system would issue an alert to a host vehicle driver whenever (i.e., every time) condition (b) occurred -- even in the absence of condition (a) occurring. Therefore, in any such combination, the Appeal 2020-004992 Application 15/276,832 7 resulting system would not issue an alert to a host vehicle driver only when both conditions (a) and (b) occur simultaneously. Id. at 9. In response, the Examiner explains Avery’s Fig. 2 depicts visual indicators alerting a driver to a plurality of potentially hazardous situations as detailed in table 1. Ans. 6. Appellant’s contention is unpersuasive of reversible Examiner error. Avery discloses issuing alerts based on various combinations of simultaneously occurring conditions. See, e.g., Avery, table 1. For example, Avery discloses a collision warning having a condition priority of 9 issued under the following conditions: “[(1) a v]ehicle speed greater than 10 mph, [(2)] target in same lane, [(3)] following interval 1–2 seconds, [(4)] target distance less than desired following distance, [and (5)] target velocity less than 101 % of host vehicle speed.” Avery, Table 1. Thus, Avery discloses issuing a particular alert only when multiple conditions are satisfied, i.e. simultaneously occur.5 Although the alert conditions found by the Examiner to be taught by Iwasaki (decreasing following distance) and Tengler (braking by a vehicle in the lane ahead) could be combined so that either 5 Although claim 1 is directed to providing an alert to a driver only in response to the simultaneous occurrence of both of two conditions, i.e., braking of and a closing distance with one or more vehicle in the lane ahead, claim 1 does not exclude a host vehicle from providing additional alerts including, for example, alerts in response to either braking or a closing distance. Similarly, claim 1 issues a particular alert “only in response to both (a) and (b) occurring simultaneously,” but the claim—read in view of the Specification—encompasses other alerts that may be sent for one of (a) and (b). See, e.g., Spec. ¶ 22 (“It is further conceivable that the higher degree of enforcement may be addition of an alert. Thus, a tactile alert or an audible alert may be added to the visual alert if the detected decrease in distance to a closest vehicle-in-front exceeds a threshold value.”). Appeal 2020-004992 Application 15/276,832 8 would result in issuing an alert, Avery teaches issuing alerts based on the occurrence of multiple, simultaneous conditions. We agree with the Examiner, therefore, that Avery teaches or suggests issuing an alert only in response to both Iwasaki and Tengler’s alert conditions occurring simultaneously, in the manner claimed. See Final Act. 6, 7. Furthermore, [w]hen there is a design need or market pressure to solve a problem and there are a finite number of identified, predictable solutions, a person of ordinary skill has good reason to pursue the known options within his or her technical grasp. If this leads to the anticipated success, it is likely the product not of innovation but of ordinary skill and common sense. KSR Int’l Co. v. Teleflex, Inc., 550 U.S. 398, 421 (2007). We note there are only a limited number of ways to combine pairs of logical conditions including the AND, OR, XOR, and NOT Boolean operators.6 Thus for this additional reason, we agree with the Examiner in finding the combined teachings of Iwasaki, Tengler, and Avery teach or suggest the limitation of claim 1’s element (c) requiring issuing an alert only in response to both (a) AND (b) occurring simultaneously. 2. Detecting a Decrease in Distance to a Closest Vehicle-In-Front of the Host Vehicle (Claim element b) Appellant further contends that Iwasaki’s disclosure of detecting a deceleration of a vehicle-in-front is not equivalent and fails to teach 6 See definition: “Boolean operator n. An operator designed to work with Boolean values. The four most common Boolean operators in programming use are AND (logical conjunction), OR (logical inclusion), XOR (exclusive OR), and NOT (logical negation).” MICROSOFT COMPUTER DICTIONARY 69 (5th ed. 2002). Appeal 2020-004992 Application 15/276,832 9 detecting a decrease in distance between vehicles as recited by claim 1’s element b. Appeal Br. 10. Appellant argues there are situations wherein a vehicle-in-front can decelerate without decreasing the distance between it and a following host vehicle such as when the host vehicle decelerates more rapidly or initiates deceleration earlier than the vehicle-in-front. Id. The Examiner responds, directing attention to, inter alia, Iwasaki’s disclosure of a decrease in a safety area AS between host vehicle 100 and vehicle 201 that is in front of host vehicle 100 upon a deceleration of forward vehicle 201. Ans. 5 (citing Iwasaki ¶¶ 53, 57; Fig. 2). The Examiner further finds Tengler’s disclosure of providing a warning when a forward vehicle is braking also teaches or suggests a decreasing distance between vehicles. We are not persuaded by Appellant’s argument that the prior art fails to teach detecting a decrease in vehicle spacing as recited by claim element (b). See, e.g., App. Br. 11. We agree with the Examiner that the limitation is taught or at least suggested by Iwasaki’s disclosure of a decrease in a safety area AS between host vehicle 100 and preceding vehicle 201 positioned in front of host vehicle 100 upon a deceleration of forward vehicle 201. See Ans. 5 (citing Iwasaki ¶¶ 53, 57; Fig. 2). We further agree with the Examiner that Tengler’s disclosure of providing a warning when a forward vehicle is braking also teaches or suggests a decreasing distance between vehicles. Id. (citing Tengler Figs. 2, 5).7 Thus, the Examiner has 7 We further note in passing and without reliance in arriving at our decision that Conrad’s disclosure of providing a warning as the distance between a vehicle and a detected object decreases (Conrad ¶ 36, claim 9) further teaches or suggests the disputed limitation of claim 1’s element b. Furthermore, Avery’s collision warning system that provides alerts when Appeal 2020-004992 Application 15/276,832 10 provided sufficient support for the finding that the recited “detecting a decrease in distance to a closest vehicle-in-front of the host vehicle” (claim 1’s element b) is taught or suggested by both Iwasaki and Tengler. See In re Preda, 401 F.2d 825, 826 (CCPA 1968) (“[I]n considering the disclosure of a reference, it is proper to take into account not only specific teachings of the reference but also the inferences which one skilled in the art would reasonably be expected to draw therefrom” (citation omitted).). In this light, Appellant’s argument (see Appeal Br. 10; Reply Br. 2)— that the Examiner has erred because Iwasaki fails to teach detecting a decreasing distance between vehicles because a decreased spacing is not inherent in Iwasaki’s deceleration of a vehicle-in-front—is unpersuasive. Appellant’s inherency-based arguments are more germane to anticipation — not obviousness as is the case here. See Trintec Indus., Inc. v. Top-US.A. Corp., 295 F.3d 1292, 1296 (Fed. Cir. 2002) (“[O]bviousness is not inherent anticipation.”). It is well settled that the test for obviousness is what the cited references’ collective teachings would have suggested to ordinarily skilled artisans. See In re Young, 927 F.2d 588, 591 (Fed. Cir. 1991). To that end, we considered not only the explicit teachings of the cited references in our decision, but also the inferences that ordinarily skilled artisans would reasonably be expected to draw from those teachings, e.g., a spacing between vehicles is often reduced when a vehicle-in-front starts braking or otherwise decelerates. See Preda, 401 F.2d at 826. inter-vehicle spacing is less than some distance or travel time further teaches or suggests detecting a decrease in distance. Avery passim. Avery’s condition priority 9 is explicitly for a vehicle condition of “2 second interval, decreasing.” Avery Table 1. Appeal 2020-004992 Application 15/276,832 11 3. Propriety of Combing the Teachings of the References Appellant contends neither Iwasaki, Tengler, nor Avery provide any teaching, suggestion, or motivation to modify the references as suggested by the Examiner. Appeal Br. 13. Appellant further argues, as follows: To the extent that the Examiner relies on official or judicial notice of facts or on common knowledge in the art to support the Examiner’s suggested modification, the Applicant does not acquiesce to and the Examiner has not cited any reference or other documentary evidence to support or corroborate any such official or judicial notice or common knowledge contention. Id. According to Appellant, any reason for combing the prior art teachings “could only have been gleaned from Applicant’s claimed invention” and, as such, constitutes impermissible hindsight reconstruction. Id. (citing Leo Pharmaceutical Products, Ltd v. Rea, 726 F.3d 1346, 1355 (Fed. Cir. 2013)). Appellant’s contention is unpersuasive of reversible Examiner error. Contrary to Appellant’s argument, “the motivation to combine need not be found in prior art references, but equally can be found ‘in the knowledge generally available to one of ordinary skill in the art.’” Nat’l Steel Car, Ltd. v. Canadian Pacific Ry., Ltd., 357 F.3d 1319, 1337 (Fed. Cir. 2004) (quoting In re Jones, 958 F.2d 347, 351 (Fed. Cir. 1992). “Evidence of a motivation to combine prior art references ‘may flow from the prior art references themselves, the knowledge of one of ordinary skill in the art, or, in some cases, from the nature of the problem to be solved.’” Medichem, S.A. v. Rolabo, S.L., 437 F.3d 1157, 1164 (Fed. Cir. 2006) (quoting Brown & Williamson Tobacco Corp. v. Philip Morris Inc., 229 F.3d 1120, 1125 (Fed. Cir. 2000)). The Examiner’s explanation of the reasons a person of ordinary skill in the art would have had to combine the prior art teachings is sufficient Appeal 2020-004992 Application 15/276,832 12 when an allowance is made for “the inferences and creative steps that a person of ordinary skill in the art would employ.” KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 418 (2007); see also PerfectWeb Techs., Inc. v. InfoUSA, Inc., 587 F.3d 1324, 1329 (Fed. Cir. 2009) (an analysis of obviousness “may include recourse to logic, judgment, and common sense available to the person of ordinary skill that do not necessarily require explication in any reference or expert opinion”). However, the analysis does not require evidence of an explicit teaching of motivation to combine, only a rationale. Ball Aerosol v. Ltd. Brands, 555 F.3d 984, 993 (Fed. Cir. 2009) (requirement for an explicit analysis does not require record evidence of an explicit teaching of a motivation to combine in the prior art); see also MPEP § 2143(I). The Examiner finds the reason to modify Iwasaki’s deceleration information to include Tengler’s brake message “is to provide a warning system to alert a driver [to] the risk of the surrounding environment.” Final Act. 6. The Examiner further finds it would have been obvious to modify the combined teaching of Iwasaki and Tengler to include Avery’s teaching of issuing an alert only in response to both (a) a braking message and (b) a decrease in vehicle spacing (i.e., distance) so as “to provide a warning indicator for various condition to alert a driver [to] maintain a safe distance with the preceding vehicle.” Id. at 7. Appellant fails to address these findings. Thus, we find the Examiner has provided the requisite “articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.” See In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006). For the reasons discussed supra, Appellant’s arguments are unpersuasive of error in the Examiner’s rejection of claim 1 under 35 U.S.C. Appeal 2020-004992 Application 15/276,832 13 103. See Appeal Br. 7–13. Appellant’s arguments in connection with independent claim 18 (id. at 14–15) are substantively repetitive of those discussed in connection with claim 1 and are unpersuasive for the same reasons. Independent claim 8 and dependent claims 2–7, 9, 12–17, and 19– 22 are not argued separately with particularity. Accordingly, we sustain the Examiner’s rejections of claims 1–9 and 12–22 under 35 U.S.C. 103(a). CONCLUSION We affirm the Examiner’s rejection of claims 1, 2, 4, 5, 7–9, 14, and 17 under 35 U.S.C. § 103(a) as obvious over the combined teachings of Iwasaki, Tengler, and Avery. We affirm the Examiner’s rejection of claim 3 under 35 U.S.C. § 103(a) as obvious over the combined teachings of Iwasaki, Tengler, Avery, and Conrad. We affirm the Examiner’s rejection of claim 6 under 35 U.S.C. § 103(a) as obvious over the combined teachings of Iwasaki, Tengler, Avery, and Burzio. We affirm the Examiner’s rejection of claims 12, 13, 15, and 16 under 35 U.S.C. § 103(a) as obvious over the combined teachings of Iwasaki, Tengler, Avery, and Rashid. We affirm the Examiner’s rejection of claims 18, 19, and 22 under 35 U.S.C. § 103(a) as obvious over the combined teachings of Iwasaki, Yurimoto, Avery, and Tengler. We affirm the Examiner’s rejection of claims 20 and 21 under 35 U.S.C. § 103(a) as obvious over the combined teachings of Iwasaki, Yurimoto, Avery, Tengler, and Rashid.
