Before T ARANTO , C HEN , and S TOLL , Circuit Judges

. C HEN , Circuit Judge

. Daedalus Blue LLC (Daedalus) appeals a Patent Trial and Appeal Board (Board) decision that determined claims 15

– 25 of U.S. Patent No. 8,671,132 (’132 patent) are unpatentable under 35 U.S.C. § 103 over combinations of Gelb, 1 Tivoli, 2 and Callaghan. 3 We have jurisdiction under 28 U.S.C. § 1295(a)(4)(A ).

Daedalus raises three arguments on appeal : (1) the Board erred by not construing the claim term “plurality of clients” as “clients in a networked environment” ; (2) Gelb is not analogous art because it is not in the same field of endeavor as the ’132 patent ; and (3) Gelb is not analogous art because it is not reasonably pertinent to the problems identified in the ’132 patent. Because substantial evidence supports the Board’s finding that Gelb is analogous art, we affirm

. Claim 15 is representative for purposes of this appeal and recites:

15. A method f or handling files within a policy

based data management system, the method comprising:

, J.A. 1500

. Case: 23-1313 Document: 36 Page: 2 Filed: 03/13/2024DAEDALUS BLUE LLC v. VIDAL 3

providing a policy set comprising at least one service class rule;
receiving one or more attributes of a file from one of a plurality of clients , the clients comprising at least two different computing platforms;
applying the service class rule to the file to assign a service class to the file; and
conducting operations on the file in a manner according to the service class.
’132 patent at claim 15 (emphasis added).

We b egin with Daedalus’s not

- reasonabl y- pertinen t argument

. T he Board agreed with Daedalus that one problem identified in the ’132 patent is “ ‘ not permit[ting] a user to automatically select between multiple storage options’ and not addressing ‘ [files] with varying storage or performance requirements or equipment with varying capacities and performance levels.’” J.A. 22 (first alteration in original) ( first quoting ’132 patent col. 1 l. 47 – col. 2 l. 3 ; and then quoting J.A. 573 ). Relying in part on Gelb’s specification , t he Board reasonably found that Gelb address es the same problem : “namely that prior art storage access methods did not permit programmers to write code that would allow users to automatically select the appropriate storage devices based on ‘high or logical level’ concepts, such as ‘data sets, data bases and the like.’” J.A. 22 (quoting J.A. 645); see also J.A. 1504 col. 1 ll. 33

– 37, 60

– 65, col. 2 ll. 19

– 21; J.A. 1512 col. 18 ll. 23 –27

. Substantial evidence therefore supports the Board’s finding that Gelb would be reasonably pertinent to at least one problem identified in the ’132 patent.

Because the Board’s reasonable

- pertinence finding is supported by substantial evidence, we need not address Daedalus’s other argume nts. E ven if Daedalus ’s claim

- construction argument were correct
, that construction would not undermine th e Board’s factual finding s for reasonable Case: 23-1313 Document: 36 Page: 3 Filed: 03/13/2024DAEDALUS BLUE LLC v. VIDAL 4

pertinence

, as th e identified problem is agnostic to whether the clients are in a networked environment. A s to Daedalus’s field -of- endeavor argument, the Board’s reasonable

pertinence finding was sufficient for Gelb to be analogous
art. See Donner Tech., LLC v. Pro Stage Gear, LLC , 979F.3d 1353, 1359 (Fed. Cir. 2020) (explaining that a reference is analogous art if it is either in the same “field of endeavor” or “reasonably pertinent to the particular problem with which the inventor is involved” (quoting In re Bigio

, 381 F.3d 1320, 1325 (Fed. Cir. 2004)) ).

We have considered Daedalus’s remaining arguments and find them unpersuasive. For the foregoing reasons, we affirm.
