Claims 1, 2, 6, 7, 10, 11, 16, 17, 21, and 22 are unpatentable; claims 3–5 are not shown unpatentable, and challenges to claims 18–20 are dismissed.

“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 shown, by a preponderance of the evidence, that claims 1, 2, 6, 7, 10, 11, 16, 17, 21, and 22 are unpatentable, but has failed to do so for claims 3–5 and 12–15. We dismiss the Petition with respect to the challenges asserted against claims 18–20.” slip op. at 2

“more than merely “selecting” times. Petitioner offers no explanation how Dr. Ikelle’s testimony that “indexed” should be construed broadly to mean “selected,” Ex. 2002, 184:8–11, would be consistent with the rest of the limitation that requires enabling separate identification of events originating from different sources. Patent Owner’s proposed construction, however, is unduly narrow to the extent it requires recording. As explained in the passage cited by Patent Owner, recording the signal and indexing are two separate aspects of the process involved in the ’981 patent. Ex. 1001, 5:62–67 (“A recording is made of the signal . . . that is indexed to a known time reference with respect to time of firing of the first source) (emphases added). The ’981 patent demonstrates that the term “indexed” is used in the “indexed” limitation according to one of its ordinary meanings that one thing is arranged in reference to another. Id.; see also id. at 6:66–7:1 (“[A] time of firing of each source with respect to a time index” is shown in Figure 4.), 8:33–40 (“[W]hen time is indexed with respect to the firing time of source A,” source B events are not coherent between firing sequences.).” slip op. at 9
- Novelty / Anticipation (§102) › Anticipation standard (single reference, every element)UnpatentableNot shown unpatentableMixed
“Although a prior art reference may anticipate when the claim limitations not expressly found in that reference are inherent in it, inherency requires that “the prior art necessarily functions in accordance with, or includes, the claimed limitations, it anticipates.” In re Cruciferous Sprout Litig., 301 F.3d 1343, 1349 (Fed. Cir. 2002). Here, Petitioner’s arguments and evidence fail to persuade us that de Kok disclosure of suppressing random noise inherently includes determining trace to trace coherence. Merely demonstrating a step may be done is not sufficient to show that step is inherently anticipated. Accordingly, based on the arguments and evidence submitted, we find Petitioner has failed to demonstrate, by a preponderance of the evidence, that de Kok anticipates claims 12 and 17. Similarly, because claims 13–15 ultimately depend from claim 12, we find Petitioner has failed to demonstrate, by a preponderance of the evidence, that de Kok anticipates claims 13–15.” slip op. at 19
- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner
“The relevant passages cited by both parties demonstrate that Beasley distinguishes between alternating and concurrent firings. See, e.g., Ex. 1004, 7:52–63. Although Herkenhoff states that the concurrent disclosure in Beasley means “exactly concurrently,” Patent Owner has not pointed to any clear disclosure in Beasley itself indicating “concurrently” should be understood as excluding any amount of time delay. Petitioner, however, has pointed to multiple references where Beasley explains that sources may be fired “simultaneously or nearly simultaneously.” Pet. Reply 15 (citing Ex. 1004, 8:46–47); Pet. 47 (quoting Ex. 1004, 1:19–25 (“The present invention, in certain aspects, is directed to seismic survey systems and methods in which two or more seismic sources are fired simultaneously, or significantly close together temporally . . . .”)); see also Ex. 1004, 1:47–51, 8:44–47, 9:5–10, 12:26–29. Moreover, claim 1 of the ’655 patent, which Patent Owner asserts claims the “first embodiment” of the ’981 patent, recites a method including the step of “substantially simultaneously launching a first acoustic wavefield,” from the leading source, “the first wavefield being characterized by a first unique code and launching a second acoustic wavefield” from the trailing source, “the second acoustic wavefield being characterized by a second unique code.” Ex. 2009, 6:46–53. Accordingly, Beasley does not exclude time delay encoding from its disclosed “concurrent” activation embodiments.” slip op. at 27
