O’M ALLEY , Circuit Judge

. Appellant Robert D. Kross (“Kross”) appeals the Patent Trial and Appeal Board ’s (“Board ’s ”) determination that claims 31

– 50 of Kross’s patent application, No. 13/275,400 Case: 20-1056 Document: 31 Page: 1 Filed: 08/11/2020IN RE : KROSS 2

(“the ’400 Application”), would have been obvious under 35 U.S.C. § 103(a). For the reasons explained below , we affirm the Board’s decision

. B ACKGROUND The ’400 Application relate s generally to non

- gelatin viscoelastic printing plates and the use of such plates in monotype printing . A monotype print is typically made by pressing a piece of paper against an inked surface. A stated object ive of the purported invention is to provide a reusable, durable , and r eadily

- cleanable gel printing plate that artists may be able to use “without a need for a press or other type of pressure tool.” J.A. 19

. Kross contends thatthe purported invention overcomes the problems of “cracking, splitting and just plain ‘falling a part
, ’” which are inherent in printing plate s made of gelatin. Appellant’s Br. 8. It is undisputed that claim 31, reproduced below, is representative. A printing method using a non

a combination thereof, and a plasticizing oil, said viscoelastic gel composition excludes gelatin and has a smooth surface formed as a sheet and shaped for use as said non

- gelatin, viscoelastic gel printing plate;
laying over said non

- gelatin, viscoelastic g el printing plate a surface onto which said layer of paint for creating a print is to be transferred; and, transferring at least a portion of said layer of paint from said non

- gelatin, viscoelastic gel printing plate to said surface via pressure for produc ing said print, said method for producing said print using said

non

- gelatin printing plate being capable of being performed either with a pressure tool, without said pressure tool and solely with the pressure being applied by a hand of a person, or with b oth said pressure tool and the pressure being applied by the hand of a person.

J.A. 34

– 35

. Claim 39, the other independent claim on appeal, further recites limitations requiring the production of a second print

. J.A. 4, 36

– 37. The examiner rejected claims 31

– 50 as obvious over at least one of five combinations of prior art references. Kross appealed to the Board, which affirmed the examiner’s rejections. In its decision affirming the examiner’s rejections, t he Board noted that this was th e third time it was reviewing “similar claims” based on the ’400 Application. J.A. 2. It rejected Kross’s argument that the purported invention represents a new use for a known material and meets a long

- felt and unmet need of solving the cracking proble ms that were a hallmark of gelatin plates. J.A. 6. The Board concluded that a person of skill in the art “ would have expected . . . that the properties of the viscoelastic gel compositions ” described in the prior art “ would likely address the Case: 20-1056 Document: 31 Page: 3 Filed: 08/11/2020IN RE : KROSS 4

[ same ] prob lems. ” J.A. 6

– 7. The Board found that the examiner’s rejections were consistent with prior findings of fact and conclusions of obviousness addressing Kross’s

now

- cancelled, similar claims for the ’400 Application

. J.A. 6. 1 For example, the Board had p reviously found that the prior art recognized the splitting and cracking problem with gelatin, and th at th is would have prompted a person of skill in the art “to consider materials having similar properties, but less prone to splitting

, ” such as the viscoelastic materials claimed by Kross. J.A. 271. Accordingly, the Board credited the examiner’s findings , noting that aperson of skill in the art would have a “reasonable expectation of successfully solving a known problem using known

pro perties of a known material.” J.A. 7 (citing In re Vaeck

, 947 F.2d 488, 493 (Fed. Cir. 1991). The Board also rejected Kross’s arguments directed to objective indicia of non

- obviousness. J.A. 7

– 9. On appeal, Kross challenges the Board’s conclusions with respect to one prior art reference combination : Singular Impressions, 2 Taylor, 3 and Chen. 4 Singular Impressions discloses monotype printing using a glass or metal printing plate , but not a gel printing plate. J.A. 587. It teaches that “ [ i ] n its purest and simplest form, a monotype

1 The Board noted that Kross’s previously rejectedclaims differed from his current claims only in their inclusion of a washing step and requirements of reusing the plates and application of pressure by hand. J.A. 4.

is made by drawing with printer’s ink or oil paint on a smooth surface such as glass or a metal plate.” Id. It also teaches that the image can be transferred to paper using hand pr essure. Id. By contrast, Taylor discloses how toprepare gelatin printing plates for use in monotype printing. J.A. 588. Chen, on the other hand, discloses non

- gelatin, gel polymers , primarily for use in medical devices. J. A

. 599. The parties agree t hat Chen does not disclose the use of these materials in the context of printing. The parties also agree that a fourth prior art reference, Germain

, 5 discloses the problems with using gelatin printing plates. J.A. 177

– 182; J.A. 306

– 312. Kross timely filed a notice of appeal. We have jurisdiction pursuant to 28 U.S.C. § 1295(a)(4).

(Fed. Cir. 2013) (citing KSR Int’l Co. v. Telefle x Inc. , 550 U.S. 398, 406 (2007 ))

. On appeal, Kross challenges the Board’s obviousness determination for a host of reasons. Kross’s main argument is that, contrary to the Board’s finding, there was no motivation to combine the prior art references. App ellant’s Br. 19

– 24. Kross further argues that the Board ’s obviousness determination is erroneous because it employs an impermissible “obvious to try” reasoning

. Id. at 24

– 29. Kross also appears to argue that the Board failed to give proper weight to his evidence of objective indicia of non

- obviousness

— specifically, that the purported invention solves a long felt but unmet need. Id. at 19

– 21; Appellant’s Reply Br. 9

– 11. We are not convinced

. As the Board explained, a person of ordinary skill in the art would have be en motivated to address the known cracking and splitting problems with gelatin printing plates using the materials identified in Chen. J.A. 5

– 6 (citing J.A. 271). 6 T he Board cited the examiner’s findings that a person of skill in the art would have recognized the problems associated with Taylor’s gelatin printing plates and then turned to Chen in looking for an alternative polymer to use in its gel printing plates. J.A. 6 (citing J.A. 491

– 98) ; J.A. 556

. Chen, with its focus on viscoelastic gels that are crack

- and tear

- resistant

, provides that alternative. See J.A. 590

. It discloses “a viscoelastic gel meeting the claimed limitations

. . . which has high dimensional stability, crack and tear resistance and long service life and capable of repeated handling.” J.A. 271. 7 Substantial

6 Kross does not dispute that both Taylor and Germain identified the drawbacks of w orking with gelatin printing plates. Appellant’s Br. 28.

7 Although this discussion refers to Kross’s now

- cancelled claims, we agree with the Board that these findings Case: 20-1056 Document: 31 Page: 6 Filed: 08/11/2020IN RE : KROSS 7

evidence thus supports the Board’s finding of a motivation to combine Chen’s viscoelastic materials with Taylor’s gel printing plates to address the known problems with gelatin printing plates. Contrary to Kross’s arguments, t he fact that Chen does not teach the use of viscoelastic compositions in any type of printing does not undermine the Board’s finding of a motivation to combine. See Appellant’s Br. 13

– 14; Appe llant’s Reply Br. 1

– 2. We agree with the Board that Chen’s silence “as to a particular application is of little or no momentgiven the teachings of the properties and the resulting general uses of the viscoelastic gel

- like materials, which would have sugg ested those materials as, more likely than not, a successful solution to the problems of gelatin cracking and splitting.” J.A. 271.
We likewise reject Kross’s argument that the Board impermissibly employed an “ obvious to try ” rationale

. Kross’s arguments in this regard focus on the Board’s statement that the “reasonable expectation of successfully solving aknown problem using known properties of a known material i[s] generally prima facie obvious.” J.A. 6

– 7. We do
not read into this statement the error that Kross complains of. This is not a case, as Kross contends, where “the priorart gave no indication of critical parameters and no direction as to which of many possibilities is likely to be successful.” Appellant’s Br. 2 4

– 25 ( quoting In re Co paxone Con sol. Cases , 906 F.3d 1013, 1025 (Fed. Cir. 2018) ). As Kross himself contends, Taylor and Germain identified the parameters that would have been of concern to a skilled artisan (cracking, splitting)

. Chen t eaches that non

- gelatin, gel polymers would be beneficial in fixing these critical parameters (high dimensional stability, crack and tear resistance)

. That is a far cry from impermissibly requiring

apply to the identical limitations in the claims at issue in this appeal. Case: 20-1056 Document: 31 Page: 7 Filed: 08/11/2020IN RE : KROSS 8

that a skilled artisan , without any guidance from the prior
art
, “ vary all parameters” until one succeeds. Kubin , 561 F.3d at 1359. Accordingly, we affirm the Board’s conclusion of obviousness.
C ONCLUSION We have considered Kross’s remaining arguments and find them unpersuasive. For the foregoing reasons, we affir m the decision of the Board.
