`BREIVIK II IS NOT PRIOR ART – TILSETH DECLARATION
`
`It cannot be disputed that the Dr. Tilseth’s testimony on conception and reduction to practice is corroborated:
`
`• Krill meal was made on board the Atlantic Navigator and stored for 13 months. Ex. 2001 ¶¶ 7-8 (citing Exs.
`2003, 2004, 1001 and 1005).1
`
`• After the storage period, the krill meal was extracted with ethanol. Ex. 2001, ¶¶9-14 (citing Exs. 2005-2014). 1
`
`• The resulting krill oil contained phospholipids including phosphatidylcholine and astaxanthin. Ex. 2001, ¶14
`(citing Exs. 2013, 1001 and 1005). 1
`
`• This method of extraction was developed at least as early as September 14, 2006. Ex. 2001, ¶15. 1
`
`• This evidence demonstrates conception and reduction to practice of at least as much of the invention as the
`reference happens to show.2
`
`• Alternatively, the evidence is sufficient to antedate if the differences are obvious.3

`BREIVIK II IS NOT PRIOR ART – RULE OF REASON
`
`•
`
`“Sufficiency of corroboration is determined by using a ‘rule of reason’ analysis, under which all pertinent
`evidence is examined when determining the credibility of an inventor’s testimony.” Medichem, S.A. v.
`Rolabo, S.L., 437 F.3d 1157, 1170 (2006).1
`
`• The “rule of reason” was developed to ease the requirement of corroboration. Coleman v. Dines, 754
`F.2d 353, 360 (Fed. Cir. 1985). 1
`
`•
`
`•
`
`“Despite the importance of the independence requirement, however, [t]he law does not impose an
`impossible standard of ‘independence’ on corroborative evidence by requiring that every point of a
`reduction to practice be corroborated by evidence having a source totally independent of the
`inventor....” Medichem, 437 F.3d at 1171. 1
`
`“Credibility concerns undergird the corroboration requirement, the purpose of which is to prevent
`fraud.” Id. Thus, the corroboration requirement provides “a safeguard against courts being deceived by
`inventors who may be tempted to mischaracterize the events of the past through their testimony.” Id. 1

`
`BREIVIK II IS NOT PRIOR ART – PETITIONER FAILS TO
`APPLY THE RULE OF REASON
`• Petitioner has failed to present any analysis under the “rule of reason.”1
`
`• Instead, Petitioner presents an analysis that focuses on alleged failure to corroborate each claim element
`as written, arguing: “Dr. Tilseth’s post-hoc interpretation of two sections from this 15-year old document
`cannot be used to backfill the gaps in what is not found within the four corners of Sections 6.1-6.2.” 2
`
`• This “four corners” analysis is inconsistent with the “rule of reason.” It is the antithesis of the rule of
`reason to require evidence on every aspect of conception and reduction to practice. E.I. du Pont De
`Nemours & Co., 921 F.3d 1060, 1077 (Fed. Cir. 2019).3
`
`• As a result, Petitioner has failed to present any evidence that undermines the credibility of Dr. Tilseth’s
`testimony.

`BREIVIK II IS NOT PRIOR ART – CREDIBILITY OF DR. TILSETH
`
`• “Credibility concerns undergird the corroboration requirement, the purpose of which is to prevent fraud.”
`Medichem, 437 F.3d at 1171. Thus, the corroboration requirement provides “a safeguard against courts
`being deceived by inventors who may be tempted to mischaracterize the events of the past through their
`testimony.” Id.1
`
`• Has Petitioner done anything to undermine Dr. Tilseth’s credibility? NO!
`
`• First, Petitioner did not depose Dr. Tilseth.2
`
`• Second, Petitioner’s only argument is that that Sections 6.1 and 6.2 of Ex. 2003 does not specifically
`mention that the krill meal was made a standard process involving a cooking stage that denatured krill
`lipases and phospholipases.3
`
`• This argument ignores corroborating evidence presented by Dr. Tilseth and admissions by it’s expert, Dr.
`Tallon.4

`
`• Petitioner focused solely on Sections 6.1 and 6.2 of Ex. 2003 and failed to consider other evidence cited by
`Dr. Tilseth.1
`
`• Dr. Tilseth also testified that the krill meal described in Table 13 of Ex. 2003 is the same meal described in
`Example 1, Table 1 of Ex. 1005 (the priority document). Ex. 2001, ¶8. The data provided in Table 13 of Ex.
`2003 (p. 0023) is repeated in Table 1 of Ex. 1005 (p. 0023).2
`
`• As described in Ex. 1005, the krill meal was made by standard methods (Example 1 at 0023). 3

`
`
`
`BREIVIK II IS NOT PRIOR ART – CREDIBILITY OF DR. TILSETH
`
`• When viewed as a whole, as required by the “rule of reason,” the corroborating evidence supports Dr.
`Tilseth’s testimony that the krill meal was made by a standard process involving cooking, pressing and
`decanting which denatured lipases and phospholipase. Ex. 2001, ¶8.1
`
`• Dr. Tallon acknowledged that the standard process involves cooking sufficient to denature lipases and
`phospholipases.2
`
`• Dr. Tallon, referencing Budziński (Ex. 1008), acknowledged that the “traditional method of krill-meal
`production is by cooking and pressing or centrifuging and drying . . . and the resulting denatured krill meal
`is stable . . . .” Ex. 1006 ¶168.2
`
`• Dr. Tallon confirmed this conclusion in his Reply Declaration: “The cooking that occurs during preparation
`of the krill meal was a well-known process in the prior art for preventing this enzymatic degradation
`allowing for stable storage of a krill meal.” Ex. 1086 ¶46.2
`
`• There is no reasonable basis to believe that Dr. Tilseth somehow manufactured his testimony in a post-hoc
`fashion as alleged by Petitioner.3

`
`• Petitioner further alleges that Dr. Tilseth has “self-corroborated” Sections 6.1 and 6.2 of Ex. 2003 and that
`Dr. Tilseth’s notes cannot corroborate his reduction to practice story.1
`
`• Metadata has been provided for each of Exs. 2003, 2005, 2008, 2010, and 2013 which provides time

`• Breivik II does not teach extraction from a stored material, and instead teaches extraction from fresh krill.1
`
`• As admitted by Petitioner “Breivik II describes a process in which fresh krill is heated to 80oC, washed with
`ethanol and then subjected to supercritical fluid extraction with CO2 and 10% ethanol to obtain an extract
`“rich in phospholipids” and astaxanthin.” ‘169 Petition at 46, ‘046 Petition at 45.2
`
`• Examples 6 and 7 both describe use of fresh krill that is heated for either five minutes or a few minutes
`immediately before extraction. Ex. 1037 (Breivik II) at 0009.3

`
`• The question becomes whether there is any motivation to substitute a stored krill meal for the fresh krill utilized

`
`• This motivation does not come from any of the other cited references, none of which teach or suggest extraction
`from a denatured krill product or krill meal that has been stored.2
`
`•
`
`In the absence of any motivation in the references themselves, Petitioner relies on the unsupported testimony of
`Dr. Tallon, arguing: “Among the reasons for extracting krill oil on land as opposed to at sea, include the expense
`of installing and operating extraction processes on a ship, and the hazards associated with using flammable polar
`solvents at sea. Because of the practicality and desirability of preforming land-based solvent extraction, a POSITA
`would have understood that denatured krill needed to be stored prior to extraction because of, inter alia, the
`temporal and geographic restrictions on krill harvesting, the distance between the krill fishing grounds and
`commercial solvent extraction facilities, and the need to intermittently schedule oil extraction to satisfy
`customer demand for freshly extracted krill oil.” ‘169/’046 Petitions at 59-60.3

`
`• Dr. Tallon’s deposition testimony undermines the unsupported rationale in his Declaration.1
`
`• When deposed, Dr. Tallon admitted that the flammability of ethanol “did not preclude it from being used
`on a ship” and that “flammable solvents can be managed.” Ex. 2019 at 0049, l. 18 – 25.2
`
`• When deposed, Dr. Tallon further admitted that factories in ships looked just like land-based factories and
`that “conceptually, many of the processes that we have been involved with could equally be installed on a
`ship as they could on land.”3
`
`• There is no basis to conclude that extraction would preferably be done on land on stored material due to
`safety concerns when: a) Breivik II teaches that extraction of fresh krill is preferable and that its processes
`can be performed on the fishing vessel; and b) Dr. Tallon admitted that solvents can be managed on-board
`a ship.4
`
`• Finally, no supporting evidence is provided to support Dr. Tallon’s speculation on economic advantages of
`extracting on land. Ex. 1006 at ¶173.5

`
`CONCLUSION
`
`• Breivik II is not prior art. Dr. Tilseth’s corroborated testimony establishes conception and reduction to
`practice prior to the November 16, 2006 critical date of Breivik II.
`
`• Since all of the Grounds in both IPR’s rely on Breivik II, removal of Breivik II as a prior art reference defeats
`every asserted Ground.
`
`• Even if Breivik II is admitted as prior art, the combined references do not teach the claim element of
`extraction from a denatured krill product or krill meal that has been stored from 1 to 24 or 1 to 36 months.
`
`• Grounds 1 and 2 of IPR2020-01532 should be denied.
