Application 15/436,129
CLAIMED SUBJECT MATTER
The claims are directed to lost circulation material (LCM) that
"includes a plurality of date tree waste fibers produced from date tree
waste." Spec. ,r 7. Claim 1, reproduced below, is illustrative of the claimed
subject matter:
1. A method to control lost circulation in a lost circulation
zone in a wellbore, comprising:
introducing an altered drilling fluid into the wellbore such
that the altered drilling fluid contacts the lost circulation zone
and reduces a rate oflost circulation into the lost circulation zone,
where the altered drilling fluid comprises a drilling fluid and a
lost circulation material (LCM), wherein the LCM comprises a
plurality of date tree waste fibers produced from date tree waste,
wherein the date tree waste comprises waste from date palm
processmg.

OPINION
Rejections 2-7
"If a ground of rejection stated by the examiner is not addressed in the

Board." MPEP § 1205.02 (8th ed., July 2010); see also MPEP § 1205.02

not present arguments or evidence showing error in those rejections. See Br.
3-12 (presenting arguments solely for the obviousness rejection based on
Burts and Stamp).
Rejection 1
We review the appealed rejection for error based upon the issues
identified by Appellant and in light of the arguments and evidence produced
thereon. Cf Ex parte Frye, 94 USPQ2d 1072, 1075 (BPAI 2010)
(precedential) (cited with approval in In re Jung, 637 F.3d 1356, 1365 (Fed.
Cir. 2011) ("it has long been the Board's practice to require an applicant to
identify the alleged error in the examiner's rejections")). After having
considered the evidence presented in this Appeal and each of Appellant's
contentions, we are not persuaded that Appellant identify reversible error,
and we affirm the Examiner's § 103 rejections for the reasons expressed in
the Final Office Action and the Answer. We add the following primarily for
emphasis.
Claim 1
Appellant argues that the Examiner reversibly erred in rejecting claim
1 5 because Stamp is non-analogous art. Br. 5. Appellant argues that
whereas the claims at issue "are directed to a lost circulation material [LCM]
for addressing the problem of controlling lost circulation in a well bore
during drilling with a drilling fluid and are in the field of oil and gas
5 Appellant does not present separate arguments for the rejection of claims 2,
4, 5, and 7-10. See, e.g., Br. 3-10. These claims, therefore, stand or fall
with claim 1. See id. 9; see also 37 C.F.R. § 4I.37(c)(l)(iv) (2013).

drilling," Stamp "is directed to the treatment of palm waste by shredding
palm fibrous waste and combining the shredded palm fibrous waste with a
dried plant mill effluent and peat to produce a soil medium." Br. 6, 7.
"Two criteria have evolved for determining whether prior art is
analogous: (1) whether the art is from the same field of endeavor, regardless
of the problem addressed, and (2) if the reference is not within the field of
the inventor's endeavor, whether the reference still is reasonably pertinent to
the particular problem with which the inventor is involved." In re Clay, 966
F.2d 656, 658-59, 23 USPQ2d 1058, 1060 (Fed. Cir. 1992). InKSR Int'!
Co. v. Teleflex Inc., 550 U.S. 398, 419-20 (2007), the Supreme Court stated
that:
In determining whether the subject matter of a ... claim
is obvious, neither the particular motivation nor the avowed
purpose of the patentee controls. What matters is the objective
reach of the claim. If the claim extends to what is obvious, it is
... [unpatentable] under§ 103. One of the ways in which a
patent's subject matter can be proved obvious is by noting that
there existed at the time of the invention a known problem for
which there was an obvious solution encompassed by the
patent's claims.
"The Supreme Court's decision in KSR . .. directs us to construe the scope
of analogous art broadly," stating that 'familiar items may have obvious uses
beyond their primary purposes, and a person of ordinary skill often will be
able to fit the teachings of multiple patents together like pieces of a puzzle."'
Wyers v. Master Lock Co., 616 F.3d 1231, 1238 (Fed. Cir. 2010) (quoting
KSR, 550 U.S. at 420).
In this case, Burts "relates to lost circulation additives comprising
polymer and fibers or comminuted plant materials, [and] to lost circulation

treatment fluids made therefrom[.]" Burts 1: 12-16. Burts provides a
lengthy "nonexhaustive list of such loss circulation" including "nut and seed
shells or hulls (peanut almond, walnut, peach, brazil, coconut, peanut,
sunflower, flax, cocoa bean, cottonseed, rice, linseed)" as well as "wood
fiber," "bark chips" and the like. Burts 2:23--47, 4:16-28, 7:12-33 (cited in
Ans. 4); see also Final Act. 5-6. On the other hand, Stamp discloses a
process for the treatment of palm waste, including fibrous date palm waste,
according to the desired end use. Stamp ,r,r 1, 14, 15, 22. Based on these
undisputed teachings of Burts and Stamp, we are unpersuaded that the
Examiner reversibly erred in finding that a skilled artisan would have
combined Burts with Stamp, which undisputedly teaches that "palm fibrous
waste" (Stamp ,r 10) is known, for the reasons presented by the Examiner.
Final Act. 3---6; see In re Clay, 966 F.2d at 658 (holding that whether a prior
art reference is "analogous" is a question of fact).
Appellant next argues that Burts does not teach or suggest that "the
LCM comprises a plurality of date tree waste fibers" as recited in claim 1
because "Burts only discloses comminuted particles of coconut hulls" and
not from date palm processing. Br. 7, 8. The record before us, however,
shows that Stamp undisputedly teaches that "palm fibrous waste" is known.
See Stamp ,r 1 O; compare Final Act. 7, with Br. 7-8. We note that while
claim 1 is a process claim without requiring any particular structure,
composition or physical property of the recited "date tree waste fibers,"
Appellant does not argue if the prior art fibrous materials differ in structure,
composition, physical properties, or other parameters. We are therefore not
persuaded that reversibly error has been identified in the Examiner's
findings here.

Appeal2019-001108
Application 15/436,129
We are likewise unpersuaded by Appellant's argument that the
"equivalency" to the recited "date tree waste fibers" must be recognized in
the prior art. Br. 8. The record in this case shows that it is known to include
various fibrous materials in a lost circulation fluid (Burts 2: 2:23--47, 4: 16-
28, 7:12-33) and palm fiber waste is a known fibrous material (Stamp ,r 10).
Appellant has not sufficiently explained why the process recited in claim 1 is
"more than the predictable use of prior art elements according to their
established functions." KSR, 550 U.S. at 417. As a result, we sustain the
Examiner's rejection of claim 1.
Claim 3
Claim 3 depends from claim 1 and additionally recites "wherein the
LCM consists of the plurality of date tree waste fibers produced from date
tree waste."
Appellant argues that whereas claim 3 requires the LCM to include
solely the recited "date tree waste fibers produced from date tree waste,"
Burts require the LCM to include other components such as "a water soluble
crosslinkable polymer and a crosslinking agent." Br. 10. Appellant,
however, does not address the Examiner's finding that Burts "treats the
fibers as a reinforcing material regardless of additional ingredients that go
into the fluid" whether the fiber material is used alone or in combination
with others. Compare Br. 10, with Final Act. 8 (citing Burts Abs., 4:11-28);
compare Ans. 10, with Reply Br. 2-8. Because these findings are
reasonable and the Appellant has not challenged them, we accept them as
facts. See In re Kunzmann, 326 F.2d 424,425 n.3 (CCPA 1964). We
accordingly sustain the Examiner's rejection of claim 3.

Appeal2019-001108
Application 15/436,129
Claim 6
Claim 6 depends from claim 1 and additionally recites "wherein the
plurality of date tree waste fibers comprise a concentration of at least 30
pounds-per-barrel (ppb) in the altered drilling fluid."
Appellant argues that the Examiner reversibly erred here because
Burts "teaches relative amounts of the various components in the alleged
LCM composition" but not "any amount of plant material in an altered
drilling fluid." Br. 11. Appellant, however, does not address the Examiner's
finding that a skilled artisan would have arrived at claim 6 based on Burts'
teaching through routine experimentation. Compare Br. 11, with Final Act.
9; compare Ans. 13-14, with Reply Br. 2-8. Because this finding is
reasonable and the Appellant has not challenged it, we accept it as fact. See
In re Kunzmann, 326 F.2d at 425 n.3. We accordingly sustain the
Examiner's rejection of claim 6.
DECISION
The Examiner's decision is affirmed.
No time period for taking any subsequent action in connection with
this appeal may be extended under 37 C.F.R. § 1.136(a). See 37 C.F.R.
§ 1.136(a)(l )(iv).
