Anticipation:
ISSUE
Does the preponderance of evidence on this record support
Examiner’s finding that Grupp teaches Appellants’ claimed invention?
FACTUAL FINDINGS (FF)
FF 1. Appellants disclose
[A] method of predicting the operating state of a bone cement
composition[, which] includes sampling the electrical
impedance of the bone cement composition and determining if
the magnitude of the electrical impedance has decreased to a
minimum impedance value. If so, a countdown timer is
executed. The length of the countdown timer may be
configured to predict end-of-work time and/or setting time of

the bone cement composition. Setting time may also be
predicted by executing a countdown timer upon the occurrence
of an inflection point in the impedance magnitude data. Setting
time may also be predicted by use of a countdown timer which
is executed when the phase of impedance of the bone cement
composition increases to a maximum phase of impedance
value.

(Spec. 2: 15 - 3: 2)
FF 2. Grupp teaches a method for determining the consistency of
bone cement, “to determine and indicate when the cement is suitable
to use, is nearing non-usability and is non[-]usable” (Ans. 5; Grupp 6-
9 and 2: 4-5).
FF 3. Grupp’s figure 6 is reproduced below for clarity:

“Fig. 6 shows the curve of dynamic viscosity of Osteopal over the
measurement time, whereby the characteristic processing points are
indicated” (Grupp 11: 16-18).
FF 4. Grupp teaches that
[T]he signal sequence … is such that when the bone cement
reaches its processing consistency the first signal 40[, green
light signal … which indicates that the bone cement can be
utilized,] is issued, and then after a specific time period,
Appeal 2011-011770
Application 11/323,871

depending on the measured dielectric properties of the bone
cement, the third signal 44[, a yellow or orange light signal,
which indicates to the operator that the bone cement has
reached a consistency such that the end of the processing period
is impending,] comes on, while the first signal 40 goes out, and
finally the warning signal 42[, a red light signal, which
indicates that the bone cement can no longer be used by the
operator,] comes on, and the other signals are out.

(Grupp 14: 1-3; 7-9; and 13-24 (emphasis added); Ans. 5-13.)
FF 5. Examiner finds that Grupp’s method “inherently has a timer/clock in
order to determine whether a predetermined amount of time has passed”
(Ans. 11).
ANALYSIS
Appellants’ claimed invention requires that “a predetermined amount
of time” must elapse before a control signal is generated (see, e.g.,
independent claims 1 and 21; see also FF 1). In contrast, Grupp’s signals
are based on the measured dielectric properties of the bone cement (FF 4; Cf.
FF 1). Examiner is correct in recognizing that some amount of time passes
between each of Grupp’s signaling events (see generally Ans. 20-22; FF 3-
4). However, in contrast to Appellants’ claimed invention, the signaling
events in Grupp’s method are not controlled by time itself, but are instead
controlled by the measured dielectric properties of the bone cement (FF 4;
App. Br. 6-11; id. at 9 (“The amount of time that has elapsed is more or less
irrelevant to Grupp’s process - only the measured dielectric properties of the
bone cement control the duration of use of the bone cement”); Reply Br. 4-8;
Cf. FF 1). Examiner failed to establish an evidentiary basis on this record to
establish that Grupp’s method “inherently has a timer/clock in order to

determine whether a predetermined amount of time has passed” (FF 5
(emphasis added)).
CONCLUSION OF LAW
The preponderance of evidence on this record fails to support
Examiner’s finding that Grupp teaches Appellants’ claimed invention.
Therefore, the anticipation rejection on this record is reversed.

Obviousness:
Does the preponderance of evidence on this record support a
conclusion of obviousness?
FACTUAL FINDINGS (FF)
FF 6. Examiner relies on Grupp as discussed above (FF 2-5; Ans. 14).
FF 7. Grupp fails to suggest an audible signal (see generally Ans. 14).
FF 8. Examiner relies on Bourlion to suggest “a method of monitoring
impedance wherein … [the] indicator is … audible, visual, or tactile” (id.).
FF 9. Examiner finds that Grupp suggests an apparatus for performing
Grupp’s method, wherein “the apparatus compris[es]: a bone cement
container …, an electrical impedance analyzer measurement chamber … and
capacitive element …, a processor electrically coupled to the electrical
impedance analyzer …” (id. at 15).
FF 10. Examiner finds that Grupp fails to suggest “a memory device
electrically coupled to … [a] processor, wherein the memory device has
stored therein a plurality of instructions which …[are] executed by the
processor” (id. 16).
FF 11. Examiner relies on Goetz to suggest “an impedance monitor
comprising a processor and a memory device electrically coupled to the

Application 11/323,871

6
processor, wherein the memory device has stored therein a plurality of
instructions … [that are] executed by the processor” (id.).
FF 12. Examiner finds that the combination of Grupp and Goetz fails to
suggest an audible signal and relies on Bourlion to make up for this
deficiency.
ANALYSIS
The rejection over the combination of Grupp and Bourlion:
Claims 3 and 23 depend from independent claims 1 and 21
respectively. Based on the combination of Grupp and Bourlion, Examiner
concludes that, at the time of Appellants’ claimed invention, it would have
been prima facie obvious “to modify the method taught by Grupp to include
[an] audible indication as taught by Bourlion by substituting one indicating
means [(e.g., sound)] for another [(e.g., light)]” (Ans. 14). Examiner fails,
however, to establish that Bourlion makes up for the deficiency in Grupp
discussed above (see App. Br. 12-13; Reply Br. 8-9).

The rejection over the combination of Grupp and Goetz:
Based on the combination of Grupp and Goetz, Examiner concludes
that, at the time of Appellants’ claimed invention, it would have been prima
facie obvious “to modify the apparatus taught by Grupp to include a
processor having memory as taught by Goetz in order to provide a flexible
analyzing means which can be easily updated by updating the
operating/analyzing instructions” (Ans. 16). Examiner fails, however, to
establish that Goetz makes up for the deficiency in Grupp discussed above
(see App. Br. 14-16; Reply Br. 9-10).

7
The rejection over the combination of Grupp, Goetz, and Bourlion:
Examiner finds that the combination of Grupp and Goetz fails to
suggest an audible signal and relies on Bourlion to make up for this
deficiency (Ans. 19). Therefore, Examiner concludes that, at the time of
Appellants’ claimed invention, it would have been prima facie obvious “to
modify the apparatus taught by Grupp to include [an] audible indication as
taught by Bourlion by substituting one indicating means for another” (id. at
20). Examiner fails, however, to establish that the combination of Goetz and
Bourlion makes up for the deficiency in Grupp discussed above (see App.
Br. 16-17; Reply Br. 10-11).
CONCLUSION OF LAW
The preponderance of evidence on this record fails to support a
conclusion of obviousness. Therefore, the obviousness rejections on this
record are reversed.
