`
`INTRODUCTION
`A. Background
`Toyota Motor Corp. (“Petitioner”) filed a corrected Petition to
`institute an inter partes review of claims 17 and 21 (“the challenged
`claims”) of U.S. Patent No. 6,012,007 (Ex. 1001, “the ’007 patent”).
`Paper 7 (“Pet.”). In our Decision on Institution, we instituted trial to review
`the patentability of claims 17 and 21 based on anticipation by Schousek1.
`Paper 16 (“Decision to Institute” or “Dec.”).
`Subsequent to institution, Signal IP, Inc. (“Patent Owner”) filed a
`Patent Owner Response. Paper 19 (“PO Resp.”). Petitioner filed a Reply to
`the Patent Owner Response. Paper 21 (“Pet. Reply”). Petitioner provides
`testimony from Scott Andrews. Ex. 1007 (“the Andrews Declaration”).
`An oral hearing was held on February 16, 2017, and a transcript of the
`hearing is included in the record. Paper 25 (“Tr.”).
`We have jurisdiction under 35 U.S.C. § 6. This Final Written
`Decision is issued pursuant to 35 U.S.C. § 318(a) and 37 C.F.R. § 42.73.
`For the reasons that follow, we determine that Petitioner has failed to show,
`by a preponderance of the evidence, that claims 17 and 21 of the ’007 patent
`are unpatentable.
`B. Related Proceedings
`Petitioner and Patent Owner indicate that the ’007 patent is the subject
`of a number of co-pending federal district court cases, including: Signal IP,
`Inc. v. Toyota Motor North America, Inc., No. 2:15-cv-05162 (C.D. Cal.)
`(“the related litigation”). Pet. 1–2; Paper 3, 2–3.

`
`IPR2016-00292
`Patent 6,012,007
`
`
`The ’007 patent is also the subject of IPR2016-00366, and was the
`subject of IPR2015-01004, which was terminated prior to issuance of a final
`written decision (IPR2015-01004, Paper 29). We issued a final written
`decision in IPR2016-00366 concurrently with this decision.
`C. The ’007 Patent
`The ’007 patent is directed to “an airbag system having seat pressure
`
`detectors [mounted] in the seat” and its method of operation. Ex. 1001,
`1:10–12. The ’007 patent explains that one “object of the invention [is] to
`discriminate in a [supplemental inflatable restraint] system between large
`and small seat occupants for a determination of whether an airbag
`deployment should be permitted” and “[a]nother object in such a system is
`to maintain reliable operation in spite of dynamic variations in sensed
`pressures.” Id. at 1:52–57.
`
`The ’007 patent describes “seat sensing system 14 [as] inhibit[ing] air
`bag deployment when a seat is empty or occupied by a small child, while
`allowing deployment when the occupant is large.” Id. at 2:55–58. An
`example is provided where the system is tuned to always inhibit airbag
`deployment for occupants weighing less than 66 pounds, and always allow
`deployment for occupants exceeding 105 pounds. Id. at 2:58–61. The seat
`occupant sensing system includes a microprocessor and sensors mounted in
`a seat monitored by the microprocessor to determine whether to inhibit
`airbag deployment. Id. at 2:61–3:7.
`
`The sensors are periodically sampled and decision measures are
`computed. Id. at 3:39–43. Decision measure computations include, for
`example, “calculating total force and its threshold, sensor load ratings and
`measure, long term average of sensor readings and its threshold.” Id. at
`
`3
`
`
`
`IPR2016-00292
`Patent 6,012,007
`
`3:49–52. A “main decision algorithm” is illustrated in Figure 9 of the ’007
`patent, reproduced below.
`
`
`Figure 9 is a flow chart illustrating the determination of an airbag
`deployment decision. The ’007 patent explains that “this algorithm will
`result in an allow or an inhibit decision, but this decision is preliminary,
`subject to subsequent filtering to obtain a final consent to deployment.” Id.
`at 4:59–61. As shown in Figure 9, a decision to allow airbag deployment
`occurs when an “Adult Lock Flag” has been set at step 94 or when the total
`force is above a threshold (“Total Force High”) at step 98. Step 98 provides
`
`4
`
`
`
`IPR2016-00292
`Patent 6,012,007
`
`an “allow” decision for airbag deployment when the total force is above a
`threshold, with no further evaluation required. Id. at 5:1–2.
`Although the decisions noted above are “preliminary,” these decisions
`are described as “preliminary” because a “final judgment of whether to
`consent to deployment is made in the decision filter.” Id. at 5:8–9. The
`decision filter counts allow and inhibit decisions to determine whether final
`consent for deployment is granted. Id. at 5:8–24. None of these decisions
`are decisions to deploy the airbag. Rather, they are decisions to determine
`whether deployment is allowed, should the circumstances for deployment
`arise (e.g., a collision).
`D. Illustrative Claim
`As noted above, Petitioner challenges claims 17 and 21. Claim 17 is
`independent, with claim 21 depending therefrom. Claims 17 and 21 are
`reproduced below:
`17. In a vehicle restraint system having a controller for
`deploying air bags, means for inhibiting and allowing
`deployment according to whether a seat is occupied by a person
`of at least a minimum weight comprising:
`seat sensors responding to the weight of an occupant to
`produce sensor outputs;
`a microprocessor coupled to the sensor outputs and
`programmed to inhibit and allow deployment according
`to sensor response and particularly programmed to
`determine measures represented by individual sensor
`outputs and calculate from the sensor outputs a
`relative weight parameter,
`establish a first threshold of the relative weight
`parameter,
`allow deployment when the relative weight parameter is
`above the first threshold,
`
`5
`
`
`
`IPR2016-00292
`Patent 6,012,007
`
`
`establish a lock threshold above the first threshold,
`set a lock flag when the relative weight parameter is
`above the lock threshold and deployment has been
`allowed for a given time,
`establish an unlock threshold at a level indicative of an
`empty seat,
`clear the flag when the relative weight parameter is
`below the unlock threshold for a time, and
`allow deployment while the lock flag is set.
`
`Ex. 1001, 7:51–8:8.
`
`21. Means for inhibiting and allowing deployment as
`defined in claim 17 wherein the relative weight parameter is the
`total force detected by all the sensors.
`
`Id. at 8:30–32.
`
`II. ANALYSIS
`A. Claim Construction
`There is no dispute that the ’007 patent is expired. See, e.g., Pet. 7.
`“[T]he Board’s review of the claims of an expired patent is similar to that of
`a district court’s review.” In re Rambus, Inc., 694 F.3d 42, 46 (Fed. Cir.
`2012). Specifically, because the expired claims of the patent are not subject
`to amendment, we apply the principle set forth in Phillips v. AWH Corp.,
`415 F.3d 1303, 1312 (Fed. Cir. 2005) (en banc) (quoting Vitronics Corp. v.
`Conceptronic, Inc., 90 F.3d 1576, 1582 (Fed. Cir. 1996)), that “words of a
`claim ‘are generally given their ordinary and customary meaning,’” as
`understood by a person of ordinary skill in the art in question at the time of
`the invention. “In determining the meaning of the disputed claim limitation,
`we look principally to the intrinsic evidence of record, examining the claim
`
`6
`
`
`
`IPR2016-00292
`Patent 6,012,007
`
`language itself, the written description, and the prosecution history, if in
`evidence.” DePuy Spine, Inc. v. Medtronic Sofamor Danek, Inc., 469 F.3d
`1005, 1014 (Fed. Cir. 2006) (citing Phillips, 415 F.3d at 1312–17).
`In our Decision to Institute, we noted that a district court issued a
`claim construction order, in a case involving the ’007 patent, that determined
`the “relative weight parameter” recited in claim 17 was indefinite. Dec. 6
`(citing Ex. 1006, 60–63). Based on the particular circumstances of this case,
`however, the grounds of unpatentability asserted by Petitioner to the
`challenged claims may be applied, despite the issue of indefiniteness,
`because dependent claim 21 makes clear that the “relative weight parameter”
`at least includes the “total force.” Pet. 9; see Vivid Techs., Inc. v. Am. Sci. &
`Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999) (“[O]nly those terms need be
`construed that are in controversy, and only to the extent necessary to resolve
`the controversy.”). Accordingly, in each of its challenges, Petitioner
`contends that Schousek’s total weight (i.e. force) parameter corresponds to
`the recited “relative weight parameter.” Pet. 20, 25–26, 40. We are apprised
`of no reason to change our determination that the “relative weight
`parameter” recited in claim 17 includes a parameter representing a total
`weight of an occupant.
`The dispositive issue now before us is whether the “allow deployment
`when the relative weight parameter is above the first threshold” limitation
`recited in claim 17 requires that a decision to “allow deployment” is always
`made “when the relative weight parameter is above the first threshold,” or if
`the claim language only requires that a decision to “allow deployment” is
`made in some circumstances, but not always, “when the relative weight
`parameter is above the first threshold.”
`
`7
`
`
`
`IPR2016-00292
`Patent 6,012,007
`
`
`Patent Owner contends that the claim requires that the decision to
`“allow deployment” is always made “when the relative weight parameter is
`above the first threshold.” PO Resp. 15 (“According to the claim, when the
`relative weight parameter is above the first threshold, deployment is
`allowed. No other requirements need be met.”). Petitioner disagrees. See
`Pet. 22 (“there is nothing about claims 17 and 21 that would exclude
`conditioning an airbag ‘allow’ or enablement decision on factors in addition
`to the total measured weight on the seat”); Pet. Reply 6–8. For the reasons
`set forth below, we determine that the claim requires the decision to “allow
`deployment” is always made “when the relative weight parameter is above
`the first threshold.”
`Looking to the written description, we note that the ’007 patent only
`describes an “allow deployment” decision always being made when the total
`force (“the relative weight parameter”) is above a “high” threshold (“the first
`threshold”) with no further requirements. See Ex. 1001, 5:1–2, Fig. 9.
`Indeed, there is no dispute that the Specification of the ’007 patent fails to
`describe any scenario where the determination of the total force being above
`the threshold (the “high” threshold) does not always result in the “allow
`deployment” decision. We appreciate that the ’007 patent explains that the
`“allow deployment” decision in Figure 9 is only a “preliminary” decision
`subject to further filtering. Ex. 1001, 4:58–61. Nevertheless, that decision is
`an “allow deployment” decision independent of any further determinations.
`The subsequent filtering is counting “allow deployment” decisions and
`“inhibit deployment” decisions, and does not impose further requirements on
`making those decisions. Id. at 5:8–24.
`
`

`
`
`
`IPR2016-00292
`Patent 6,012,007
`
`
`In addition to the “allow deployment when the relative weight
`parameter is above the first threshold” limitation, claim 17 further requires,
`inter alia: (1) “a lock threshold above the first threshold,” (2) “set[ting] a
`lock flag when the relative weight parameter is above the lock threshold and
`deployment has been allowed for a given time,” and (3) “allow[ing]
`deployment while the lock flag is set.” Under Petitioner’s proposed reading
`of the claim noted above (see Pet. 22), “allow[ing] deployment while the
`lock flag is set” necessarily means “allow[ing] deployment when the relative
`weight parameter is above the first threshold” because the claim specifically
`requires that the “lock threshold [is] above the first threshold.” Accordingly,
`reading the claim to only require a decision to “allow deployment” in some
`circumstances, but not always, “when the relative weight parameter is above
`the first threshold,” has no effect on what falls within the scope of the claim
`because that limitation would always be met when the further requirement to
`“allow deployment while the lock is set” is met. We determine, therefore,
`that Petitioner’s proposed reading of the claim language at issue would
`render the “allow deployment when the relative weight parameter is above
`the first threshold” limitation superfluous, which counsels against that
`reading. See Bicon, Inc. v. Straumann Co., 441 F.3d 945, 950 (Fed. Cir.
`2006) (discussing the claim construction principle that meaning should be
`given to all of a claim’s terms).
`Taking the circumstances discussed above into consideration, we
`determine that the phrase “allow deployment when the relative weight
`parameter is above the first threshold” requires that an “allow deployment”
`decision is always made “when the relative weight parameter is above the
`
`9
`
`
`
`IPR2016-00292
`Patent 6,012,007
`
`first threshold.” That reading of the claim gives meaning to all limitations
`recited in the claim and is in line with the Specification of the ’007 patent.
`B. Anticipation by Schousek
`Petitioner contends that claims 17 and 21 are anticipated by Schousek.
`Pet. 4–5, 12–30.
`Schousek is directed to an airbag restraint system, and describes
`sensors located beneath a seat cover used to determine a total weight
`parameter in its airbag restraint system. Ex. 1002, Abstract, 4:51–60.
`Schousek describes a “minimum threshold” corresponding to a minimum
`weight of an occupied infant seat and a “maximum . . . threshold”
`corresponding to a maximum weight of an occupied infant seat. Id. at 2:31–
`34. Schousek explains that “[i]f the total weight parameter is greater than
`the maximum infant seat weight . . . a decision is made to allow
`deployment,” and “if the total weight parameter is less than the minimum
`weight threshold for an occupied infant seat . . . a decision is made to inhibit
`deployment.” Id. at 5:32–39. Schousek further explains that if the total
`weight parameter is between the minimum and maximum weight thresholds,
`airbag deployment is still allowed if the center of weight distribution is not
`forward of a reference line. Id. at 5:42–50.
`Figure 5A of Schousek, reproduced below, illustrates the subsequent
`conditions required for an allow deployment decision when the total weight
`parameter is between the minimum and maximum weight thresholds.
`
`10
`
`
`
`IPR2016-00292
`Patent 6,012,007
`
`
`
`Figure 5A of Schousek is a flow chart illustrating the determination of an
`airbag deployment decision. As seen at step 72, when the total weight
`parameter is between the minimum and maximum weight thresholds a
`subsequent determination is required at step 82, sometimes resulting in an
`allow deployment decision (step 86) and other times a decision not to allow
`deployment (step 84). Ex. 1002, 5:32–50.
`Although, as noted above, Schousek explains that “[i]f the total
`weight parameter is greater than the maximum infant seat weight . . . a
`decision is made to allow deployment,” Petitioner does not cite Schousek’s
`
`11
`
`
`
`IPR2016-00292
`Patent 6,012,007
`
`“maximum” threshold as corresponding to the “first threshold” in claim 17.
`See Pet. 22–23, 27 (citing Schousek’s “maximum” threshold as
`corresponding to the “lock threshold” in claim 17). Rather, Petitioner cites
`Schousek’s “minimum” threshold as corresponding to the “first threshold” in
`claim 17. Id. at 21–22, 26. As explained above, we determine that claim 17
`requires that an “allow deployment” decision is always made “when the
`relative weight parameter is above the first threshold.” It is clear that an
`allow deployment decision is not always made in Schousek when the total
`weight parameter (the relative weight parameter) is above the minimum
`weight threshold (the first threshold), and Petitioner does not contend
`otherwise. See id. at 21–23, 26–27.
`
`Accordingly, Petitioner has failed to establish by a preponderance of
`evidence that claims 17 and 21 are anticipated by Schousek.
`
`III. CONCLUSION
`For the foregoing reasons, we determine that Petitioner has failed to
`establish unpatentability of claims 17 and 21 of the ’007 patent.
`
`IV. ORDER
`For the reasons given, it is
`ORDERED that Petitioner has failed to establish unpatentability of
`claims 17 and 21 of U.S. Patent No. 6,012,007; and
`FURTHER ORDERED that parties to the proceeding seeking judicial
`review of this Final Written Decision must comply with the notice and
`service requirements of 37 C.F.R. § 90.2.
