`IV.
`
`THE '375 PATENT AND ITS PROSECUTION
`A.
`The '375 Patent
`
`The '3 7 5 patent is entitled "Method of Inhibiting or Allowing Airbag Deployment"
`
`and was issued on March 24, 1998 from U.S. Application Serial No. 08/566,029 ("the '029
`
`application"), filed December 1, 1995.
`
`The alleged invention of the '375 patent is directed to a method for using seat sensors
`
`to determine seat occupancy for control of airbag deployment. Col. 1, lines 7 to 9. For
`
`example, according to the '375 patent, a child in an infant seat may occupy a passenger seat
`
`in a vehicle, and in such instances it may be desirable to inhibit airbag deployment. Col. 1,
`
`lines 13 to 30.
`
`In purporting to determine whether an adult or a child occupies the passenger seat in a
`
`vehicle, and if a child in an infant seat occupies the seat, whether it is facing the front or the
`
`rear of the vehicle, the '375 patent, referring to Figure 2, describes that a dozen pressure
`
`sensors, placed at positions on the passenger seat, are coupled with a microprocessor that
`
`interprets the data and determines whether to deploy or inhibit deployment of an airbag. Col.
`
`2, line 63 to col. 3, line 10. Figure 2, which illustrates sensors both in the center of the seat
`
`bottom as well as near the edges of the seat, is reproduced below.

`
`Specifically, the '375 patent describes that if the total force measured by the weight
`
`sensors in the passenger seat is above a certain upper threshold, deployment is allowed, while
`
`if the total force is below a certain lower threshold, deployment is inhibited. Col. 5, lines 12
`
`to 15. If the total force is between the upper and lower thresholds, the local force
`
`measurements of force sensor groups are compared to high and low thresholds. If any local
`
`sensor group (e.g., from the front, rear, left, or right of the seat) has a force above that
`
`prescribed high threshold, deployment is allowed. Col. 5, lines 15 to 19.
`
`B.
`
`Prosecution of the '375 Patent
`
`The below discussion ofthe prosecution ofthe '375 patent is limited to claims 1 and
`
`7, i.e., the claims for which reexamination is requested.
`
`As described above, the '029 application was filed December 1, 1995. As filed, the
`
`'029 application included 22 claims, including independent claim 1 and dependent claim 7,
`which depends from claim 1. Claim 1,1 as filed, is reproduced below:
`
`1. A method of airbag control in a vehicle having an array of
`force sensors on the passenger seat coupled to a controller for
`determining permission for airbag deployment based on sensed
`force and force distribution comprising the steps of:
`
`measuring the force detected by each sensor;
`
`calculating the total force of the sensor array;
`
`Claim 1 of the '029 application issued as claim 1 of the '375 patent, i.e., the only independent claim for
`which reexamination is requested herein.
`
`3
`
`10
`
`
`
`allowing deployment if the total force is above a first threshold
`and inhibiting deployment if the total force is below a second
`threshold;
`
`defining seat areas each having a group of sensors;
`
`determining a local pressure area when the total force IS
`concentrated in a seat area;
`
`for each group calculating the group force as the sum of sensor
`forces;
`
`for a group in a local pressure area, allowing deployment if the
`group force is greater than a threshold for that group;
`
`determining a fuzzy value for the array; and
`
`allowing deployment if the fuzzy value exceeds a threshold.
`
`On March 27, 1997, an Office Action was mailed in which claims 1 and 17 were
`
`rejected as obvious in view of the combination of U.S. Patent No. S,474,327 ("Schousek")
`
`and U.S. Patent No. S,570,301 ("Barrus").
`
`With respect to the obviousness rejection of claims 1 and 7, the Examiner stated:
`
`Schousek discloses a method of airbag control in a vehicle
`having an array of force sensors on the passenger seat coupled
`to controller for determining permission for airbag deployment
`based on sensed force and force distribution comprising the
`steps of measuring
`the
`force detected by each sensor
`calculating the total force of the sensor array, allowing
`deployment if the total force is above a first threshold and
`inhibiting deployment if the total force is below a second
`threshold, defining seat areas each having a group of sensors
`(see figure SA and the related text). Schousek also discloses
`that the method includes the steps of determining a local
`pressure area when the total force is concentrated in a seat area
`and calculating the group force as the sum of sensor forces, and
`allowing deployment if the group force is greater than a
`threshold for that group (see figure SA, steps 70, 82, 64, 86 and
`the related text).
`
`Office Action, pages 3 to 4.
`
`While the Examiner concluded that Schousek does not include "a step of determining
`
`a fuzzy value for the array and allowing deployment if the fuzzy value exceeds a threshold,"
`
`the Examiner referred to Barrus, stating:
`
`4
`
`11
`
`
`
`Barrus suggests a system for unencumbered measurement and
`reporting of body structure which using a trained neural
`network (fuzzy logic) for estimating positional attitude by
`comparing the outputs of the array sensors (see figures 5 and 6)
`to pre-determined outputs of the sensors corresponding to a
`plurality of pre-determined postures (see figures 7 A to 9,
`column 3, lines 29-36, and column 6, lines 50-66).
`
`Office Action, page 4.
`In an Amendment filed on June 9, 1997, the Applicant amended claim 1 as follows: 2
`
`1. A method of airbag control in a vehicle having an array of
`force sensors on the passenger seat coupled to a controller for
`determining
`[permission
`for] whether
`to allow air bag
`deployment based on sensed force and force distribution
`comprising the steps of:
`
`measuring the force detected by each sensor;
`
`calculating the total force of the sensor array;
`
`allowing deployment if the total force is above a [first] total
`threshold force [and inhibiting deployment if the total force is
`below a second threshold];
`
`defining a plurality of seat areas [each having a group of
`sensors], at least one sensor located in each seat area;
`
`determining the existence of a local pressure area when the
`calculated total force is concentrated in [a] one of said seat
`[area] areas;
`
`[for each group] calculating [the group] a local force as the sum
`of [sensor] forces sensed by each sensor located in the seat area
`in which the total force is concentrated; and
`
`[for a group in a local pressure area,] allowing deployment if
`the [group] local force is greater than a predefined seat area
`threshold force [for that group,]
`
`[determining a fuzzy value for the array; and]
`
`[allowing deployment if the fuzzy value exceeds a threshold].

`
`
`
`In characterizing the amendments made to claim 1 the Applicant stated:
`
`Claim 1 has been amended to recite a method of airbag control
`in which deployment is allowed based on total force above a
`threshold or a local concentrated force above a threshold.
`
`Amendment, page 10.
`
`Further, in responding to the obviousness rejection, the Applicant acknowledged
`
`similarities between Schousek but argued that Schousek does not disclose determining a local
`
`pressure area or calculating a local force:
`
`Schousek is similar to Applicant's disclosed control method in
`that (1) it is directed to a method of determining whether to
`allow deployment of airbags based upon the sensed force on a
`passenger seat, (2) deployment is allowed if a total of the
`sensed forces exceeds a threshold, and (3) the total force is used
`to discriminate between adults and children. However, that is
`where the similarity ends. The additional aspects of Schousek -
`such as the discrimination between front and rear facing infant
`seats (or out of position occupant) based on a calculated center
`of weight relative to a reference line - are irrelevant to, or teach
`away from, Applicant's claimed invention. Thus, Schousek
`clearly does not, as stated by examiner, disclose the method of
`determining a local pressure area when the total force is
`concentrated in a seat area and calculating a local force as the
`sum of forces sensed by sensors located in that seat area, the
`portions of Schousek referenced by the examiner teach only
`that center of weight calculations should be used to distinguish
`between front and rear facing infant seats.
`
`Amendment, page 11.
`
`In further arguing that the combination of Schousek and Barrus did not render the
`
`pending claims obvious, the Applicant stated:
`
`Applicant's invention is particularly directed to an airbag
`deployment method in which various techniques are used to
`determine if an occupant is suitably positioned on a passenger
`seat. These
`techniques do not utilize center of weight
`calculations as taught by Schousek, nor do they utilize neural
`networks as
`taught by Barrus. Although Applicant has
`disclosed the use of pattern recognition to identify the presence
`of an infant seat, pattern recognition is not used to identify the
`position of an occupant, as taught by Barrus.
`
`Amendment, page 12.
`
`Further, with respect to claim 1, the Applicant argued:
`
`Applicant's Claim 1 defines a method wherein the controller
`determines the existence of a local pressure area when the total
`6
`
`13
`
`
`
`force is concentrated in one of the predefined seat areas, and in
`such event, sums the forces of the sensors located in that seat
`area for comparison with a seat area threshold force to
`determine if deployment should be allowed. There is no
`teaching of this sort in either Schousek or Barrus. According to
`Schousek, the controller computes the center of weight from all
`of the sensors, and compares it with a reference line, according
`to Barrus, the controller would look for a recognizable
`occupant force pattern from all of the sensors. Since neither
`Schousek nor Barrus contain a teaching that suggests the
`claimed invention, no combination of Schousek and Barrus can
`be said to obviate the claimed invention.
`
`Amendment, pages 13 to 14.
`
`The Examiner issued a Notice of Allowance on September 9, 1997, which included
`
`the following statement by the Examiner of reasons for allowance:
`
`After carefully reviewing the application in light of the
`a.
`prior art of record, the amended claims and additional search of
`all the possible areas relevant to the present applications, a set
`of related prior art references has been found, but those prior art
`references are not deemed strong to make the application
`unpatentable. Thus, it is found that the application is now in
`condition for allowance.
`
`the prior art disclose several claimed
`Although
`b.
`limitations, none of the references teaches a method of airbag
`control in a vehicle having an array of force sensors on the
`passenger seat coupled to a controller for determining whether
`to allow airbag deployment based on the sensed force and the
`force distribution which includes the steps of defining a
`plurality of seat area in which each area includes at least one
`sensor, determining the existence of a local pressure area when
`the calculated total force of the sensor array is concentrated in
`one of the seat areas, calculating a local force as the sum of
`forces sensed by each sensor located in the seat area in which
`the total force is concentrated, and allowing deployment if the
`local force is greater than a predefined seat area threshold force
`(claim 1).
`
`d.
`In the Schousek reference (5,474,327), the total weight
`and weight distribution are calculated and are used to
`distinguish the presence of an adult, an infant seat facing
`forward, or an infant sear facing rearward, and the inhibition
`deployment of the airbag is based on the presence of an adult,
`presence and position of an infant seat. However, Schousek
`does not disclose the steps of determining the local force as the
`sum of forces sensed by each sensor located in the seat area,
`
`7
`
`14
`
`
`
`and allowing deployment if the local force is greater than a
`predefined
`seat area. Moreover,
`the Barrus
`reference
`(5,570,301) neither teaches the use of pattern recognition to
`identify the presence of an infant seat, nor the comparison of
`the sum of the fuzzy local force and the fuzzy total force
`contribution values with a predefined fuzzy threshold.
