CLAIMED SUBJECT MATTER
The claims are directed to a seismic streamer for underwater towing.
Claim 16, reproduced below, is illustrative of the claimed subject matter:
16. A seismic streamer for underwater towing at a towing
speed in ice-free or wholly or partially icy water, the streamer
comprising:
birds spaced along the seismic streamer, the streamer
including the birds and any other equipment connected to the
seismic streamer has negative buoyancy, the birds have
adjustable wings that can be set so that the birds during
movement in the water apply an upward or downward force on
the seismic streamer; and
buoyant bodies spaced along the seismic streamer
configured for water to flow around the buoyant bodies during
towing underwater, the buoyant bodies are connected to the
seismic streamer by spacer elements, wherein the seismic
streamer including the birds, the buoyant bodies with associated
spacer elements and the any other equipment together have
positive buoyancy so that when the streamer is stationary the
seismic streamer rises towards the surface until the buoyant
bodies reach the surface and the seismic streamer remains
underwater by a length of the spacer elements to avoid damage
to the seismic streamer from floating ice and avoid hydrostatic
damage to the seismic streamer from sinking, and when the
seismic streamer is moving through the water the birds submerge
the buoyant bodies underwater.

OPINION
Claims 16, 18, 20, 24, and 31
Appellant argues claims 16, 18, 20, 24, and 31 as a group. Appeal Br.
7–16. We select claim 16 as representative. Claims 18, 20, 24, and 31 stand
or fall with claim 16. See 37 C.F.R. § 41.37(c)(1)(iv).
The Examiner finds that Gagliardi teaches each limitation recited in
claim 16, other than “birds spaced along the seismic streamer.” Final Act.
5–6 (citing, e.g., Fig. 9A). The Examiner finds that “Olivier teaches birds
spaced along the seismic streamer” and reasons that “[i]t would have been

obvious . . . to modify the system of Gagliardi with the birds of Olivier since
such a modification would have improved the depth control.” Id. at 6 (citing
Olivier 1:31–34).
Appellant asserts that “G[a]gliardi does not specifically show any
drawings depicting floats attached to streamers by a spacer element.”
Appeal Br. 15 (internal quotations omitted). As the Examiner clearly
explains, however, Gagliardi teaches streamers coupled to flotation devices
200A–D. Ans. 7 (citing Gagliardi 9:6–11). The cited portion of Gagliardi
explains that “floatation devices 200A-D can support other types of sources,
such as . . . streamers.” Gagliardi 9:6–11. Appellant does not dispute any
other finding relied on by the Examiner in the rejection of claim 16.
In response to the Examiner’s proposed modification, Appellant
contends that “the bird of Olivier is ice resistant and constructed to contact
ice” and “the ice resistant bird of Olivier would be mounted where the depth
control devices 218 are mounted in Gagliardi,” which “results in a structure
in which the ice resistant bird of Olivier can contact the ice as it was
constructed for.” Appeal Br. 9; see also Reply Br. 5–9.
As the Examiner explains, however, the proposed modification
includes the “birds spaced along the seismic streamer,” as recited in claim
16, not replacing Gagliardi’s buoys with Olivier’s birds. See, e.g., Ans. 5–8.
Appellant does not dispute that birds are well known. See Reply Br. 11
(“birds are well known”). Although Appellant contends that Olivier’s birds
are ice resistant, there is no dispute that Olivier teaches birds disposed along
a seismic streamer. Indeed, the portion of Olivier cited by the Examiner
explains that “depth control devices, commonly referred to as ‘cable leveling

Application 15/311,208

5
birds’ because they bear some visual resemblance to water fowl, are attached
to the cable at intervals along its length.” Olivier 1:31–34.
Appellant additionally contends that “G[a]gliardi cannot possibly
show the appropriate positive and negative buoyancy as argued by the
Examiner” because “G[a]gliardi does not even disclose the claimed birds.”
Appeal Br. 15. This is not persuasive of error because we do not read the
Examiner’s rejection as making a finding that Gagliardi teaches the
“streamer including the birds . . . ha[ving] a negative buoyancy” and having
a “positive buoyancy” with the addition of the seismic streamers.3 Rather, in
the proposed modification, which includes “birds” taught by Olivier,
Gagliardi’s system would be adjusted to account for the addition of the
birds. See Ans. 9–10.
Throughout the Appeal Brief, Appellant contends that various other
figures in Gagliardi (e.g., Figs. 9C, 9D, 11A) do not support the Examiner’s
rejection. See Appeal Br. 8–16. As the Examiner explains, “Appellant’s
arguments with regards to the depth controlling devices of the embodiments
or Figures 9C, 9D, and 11A [d]o not address the Examiner’s rejection which
cites the embodiment shown in Figure 9A.” Ans. 10–11.

3 Claim 16 recites that “the streamer including the birds and
any other equipment connected to the seismic streamer has negative
buoyancy” (emphasis added) and subsequently recites that “the seismic
streamer including the birds, the buoyant bodies with associated spacer
elements and the any other equipment together have positive buoyancy”
(emphasis added). Appellant and the Examiner appear to consider the “any
other equipment” in the initial instance defining the “negative buoyancy” as
not including the “buoyant bodies,” which is consistent with the discussion
in the Specification.

Appellant also alleges that “Olivier teaches away from the claimed
invention and also away from the theoretical structure created by the
Examiner” because “Oliv[i]er teaches to configure the Oliv[i]er birds to be
ice resistant so that the birds can contact the ice.” Appeal Br. 16. This does
not teach a way from using birds in their conventional manner, which
Olivier expressly teaches, as explained above. See Olivier 1:31–34 (“‘cable
leveling birds’ . . . are attached to the cable at intervals along its length”).
For the reasons explained above, Appellant does not identify error in
the rejection of claim 16. Claims 18, 20, 24, and 31 fall with claim 16.
Claims 26 and 27
The Examiner’s findings regarding claims 26 and 27 are similar to
those with respect to claim 16, relying on Gagliardi teaching the features
recited, other than those related to the “birds.” Final Act. 7–9. Appellant
responds that “that the Examiner’s argument [regarding the birds] is
nonsensical” because the “birds” are referenced in the Examiner’s discussion
of findings related to Gagliardi. Appeal Br. 18.
In the Answer, the Examiner “admit[s] that the rejection was sloppily
written,” and clarifies that “[t]he birds of Olivier are taught as being capable
of exerting a downwards force when towed” and “[t]he wings of the bird
only cause force to be exerted on the cable when the vessel is moving,
therefore when the vessel ceases movement, the downwards force would
also cease.” Ans. 12–13 (citing Olivier 3:39–45). That is, the Examiner
makes clear that the rejection relies on modifying the teachings of Gagliardi
based on those from Olivier for the features associated with the “birds.” In
response, Appellant reiterates unpersuasive arguments presented with
respect to claim 16. See Reply Br. 17–19.

Accordingly, we are not apprised of error in the Examiner’s decision
to reject claims 26 and 27.
Claim 17
Claim 17 depends from claim 16, and Appellant does not provide
separate argument for claim 17. See Appeal Br. 18–19 (“Silvey does not
provide the deficiencies of Gagliardi and Olivier.”).
Claims 19, 23, and 28
Claim 19 depends from claim 16, and further recites that “the spacer
elements are formed by rigid or semi-rigid elements.” The Examiner finds
that “Toennessen teaches the spacer elements are formed by rigid or semi-
rigid elements (Fig 11: 20a),” and reasons that “[i]t would have been
obvious . . . to modify the system of Gagliardi with the rigid spacer elements
of Toennessen since such a modification would have provided stability and
better control over positioning of the elements.” Final Act. 11.
Appellant acknowledges that “To[e]nnessen discloses that ‘Extensions
20a, 20b may be fixed or may have some degree of rotation; although their
main function is to support the buoyancy and weight elements, they may
contribute Some lateral force, for example if they have a hydrofoil shape,’”
but disputes the Examiner’s findings, contending that “element 20a cited by
the examiner is not even a spacer element.” Appeal Br. 19 (quoting
Toennessen ¶ 39). Although Appellant alleges that extension 20a is not a
spacer, Appellant fails to identify any structure missing from Toennessen.
Ans. 13–14.

Claim 23 depends from claim 16 and claim 28 depends form claim 27.
Appellant does not provide separate argument for those claims. See Appeal
Br. 20.
Claim 25
Claim 25 depends from claim 16, and further recites that “the buoyant
bodies have a tail for stabilizing the movement of the buoyant bodies when
towed underwater.” The Examiner finds that “Hovland teaches the buoyant
bodies have a tail for stabilizing the movement of the buoyant bodies when
towed underwater,” and reasons that “[i]t would have been obvious . . . to
modify the system of Gagliardi with the tail of Hovland since such a
modification would have stabilized the system.” Final Act. 12 (citing
Hovland 4:14–15). Appellant responds by quoting column 4, lines 13–17 of
Hovland and concluding that “Hovland does not disclose the claimed
buoyant bodies having a tail.” Appeal Br. 20.
As Appellant acknowledges, Hovland teaches “a surface reference
buoy 101 with a tail fin 104 for stabilizing movement in the water.”
Hovland 4:13–14 (emphasis added). Without further explanation as to why
this does not teach the tail recited in claim 25, we are not apprised of error in
the Examiner’s finding.
CONCLUSION
The Examiner’s rejections are affirmed.
