 2                            NICHIA CORPORATION v. DSS, INC.

 Before MOORE, Chief Judge, STOLL and CUNNINGHAM, Cir-
                      cuit Judges.
 MOORE, Chief Judge.
      Nichia Corporation appeals a Patent Trial and Appeal
 Board final written decision holding claims 1–4, 8, and 11
 of the U.S. Patent No. 6,879,040 are not unpatentable. We
 affirm.
                        BACKGROUND
     The ’040 patent, which is owned by DSS, Inc., relates
 to improvements in surface mount technology, wherein de-
 vices are mounted directly on a surface without being
 plugged into it. ’040 patent at 1:10–12. The patent ad-
 dresses the need for surface mounted opto-electronics, such
 as light emitting diodes (LEDs), to have a small footprint,
 while maintaining low thermal resistance. Id. at 2:48–53.
 The ’040 patent solves this problem by disclosing surface
 mountable electronic devices with electrical connections in
 recesses to allow solder to connect the device to the surface.
 Id. at 1:4–7. The disclosed surface mountable device in-
 cludes at least two electrically conductive members in the
 underside that bend upwards at an angle to form a recess.
 Id. at 3:40–59.
     Claim 1 is the sole independent claim at issue and re-
 cites:
     1. A surface mountable electronic device, compris-
     ing:
     a packaged body having a mounting surface, the
     mounting surface having a plurality of recesses at
     side edges of the body and
     a plurality of electrical contacts, each of which ex-
     tends from an interior portion of the mounting sur-
     face and terminates in one of said recesses, and
     each of which conforms to one of said recesses,
     wherein said recesses and electrical contacts are

     sized to provide offsets between said mounting sur-
     face and said electrical contacts.
 Id. at claim 1 (emphases added).
     Nichia filed a petition for inter partes review challeng-
 ing claims 1–4, 8, and 11 of the ’040 patent. In its petition,
 Nichia proposed constructions for several terms, including
 “mounting surface” to mean “planar surface at which the
 device is mounted, which surface is essentially co-planar
 with the planar bottom surface of the body, and which sur-
 face does not follow the contours of its recesses.” J.A. 115.
 The Board instituted the petition and requested the parties
 address “the proper construction of the claim terms ‘mount-
 ing surface’ and ‘recesses.’” J.A. 674. DSS did not provide
 a construction for “mounting surface.” J.A. 1182 n.1. The
 Board issued a final written decision holding Nichia had
 not met its burden to show the challenged claims were un-
 patentable. Nichia Corp. v. Document Security Systems,
 Inc., IPR2020-00908, 2021 WL 6335708 (P.T.A.B. Nov. 16,
 2021) (Decision). In reaching its conclusion, the Board con-
 strued “mounting surface” as including the recesses in the
 mounting surface itself such that a single planar surface
 cannot satisfy the limitation. Id. at *4. The Board also
 concluded the embodiment shown in Figure 4A does not fall
 within the scope of claim 1. Id. Nichia appeals. We have
 jurisdiction under 28 U.S.C. § 1295(a)(4)(A).
                         DISCUSSION
     We review the Board’s claim construction de novo and
 review any necessary subsidiary factual findings based on
 extrinsic evidence for substantial evidence. HTC Corp. v.
 Cellular Commc’ns Equip., LLC, 877 F.3d 1361, 1367 (Fed.
 Cir. 2017). Claim terms are generally given their plain and
 ordinary meaning, i.e., the meaning the terms would have
 to a person of ordinary skill in the art when read in the
 context of the claim, specification, and prosecution history.
 Phillips v. AWH Corp., 415 F.3d 1303, 1312–13 (Fed. Cir.
 2005) (en banc).

 4                            NICHIA CORPORATION v. DSS, INC.

      The Board construed “mounting surface” to mean a
 mounting surface with recesses in the surface itself and
 concluded the claim term does not encompass a single pla-
 nar surface. Decision, at *4. Nichia appealed arguing that
 the Board’s partial construction creates a logical impossi-
 bility such that the claims cannot be compared to the prior
 art. We do not agree. The claim language and written de-
 scription support the Board’s construction requiring a
 mounting surface having recesses. Claim 1 expressly re-
 quires “the mounting surface having a plurality of recesses
 at the side edges of the body.” ’040 patent at claim 1 (em-
 phasis added). Additionally, the ’040 patent repeatedly de-
 scribes the invention as having a mounting surface with
 recessed portions in it. For example, the patent describes
 a surface mountable electronic device with “a body with a
 first, mounting surface,” wherein the “first surface is re-
 cessed with recessed portions in it.” Id. at 3:60–67; see also
 id. at 2:54–57, 5:1–15, 5:48–65, 8:24–33.
     The written description, specifically Figure 4A, also
 supports the Board’s conclusion that the claimed mounting
 surface does not encompass a single planar surface. Figure
 4A illustrates an embodiment of the invention:

 As shown in Figure 4A, the surface mountable opto-elec-
 tronic device 400 includes an optically transparent body
 402, two electrical contacts, 404, 406, and a LED 408. Id.
 at 4:60–63. The two electrical contacts are mounted in the
Case: 22-1704     Document: 47      Page: 5     Filed: 11/02/2023

 underside 410, which is the mounting surface of the device.
 Id. at 5:1–4. Each electrical contact includes a first portion
 containing a diagonally upward extending portion 412, 414
 and a horizontal portion 416, 418. Id. at 5:7–11. Recesses
 420, 421 are formed between the first portions of the elec-
 trical contacts and a flat surface on which the device is
 mounted. Id. at 5:11–15.
     As the Board explained, the embodiment in Figure 4A
 describes both a mounting surface and a separate flat sur-
 face on which the device is mounted. Decision, at *4 (citing
 ’040 patent at 5:3–14). The electrical contacts are mounted
 in the underside of the device—i.e., the mounting surface—
 and follow a zigzag configuration that creates recesses be-
 tween the contacts and “a flat surface on which the device
 is mounted.” ’040 patent at 5:3–14; see also Decision, at *4–
 5. Because Figure 4A includes both a non-planar mounting
 surface and a separate planar surface on which the device
 is mounted, the claimed mounting surface cannot be a sin-
 gle planar surface. Decision, at *4–6; see also J.A. 1287–89
 (explaining why Figure 4A cannot support Nichia’s conten-
 tion that mounting surface should be construed as a plane).
 Therefore, the Board’s construction follows the ordinary
 meaning of “mounting surface” in light of the intrinsic evi-
 dence as would have been understood by a skilled artisan.
      Nichia argues the Board’s construction is incomplete as
 it fails to resolve an apparent logical impossibility in claim
 1 requiring the electrical contacts to both conform to the
 recesses in the mounting surface and be offset from the
 mounting surface. Appellant’s Br. at 56–63. According to
 Nichia, the Board erroneously relied on this requirement
 to find the prior art lacks an element of the claim. Id. at
 62–63. We do not agree.
     First, the Board is required to construe “only those
 terms . . . that are in controversy, and only to the extent nec-
 essary to resolve the controversy.” Vivid Techs., Inc. v. Am.
 Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)
Case: 22-1704    Document: 47      Page: 6    Filed: 11/02/2023

 6                            NICHIA CORPORATION v. DSS, INC.

 (emphasis added). This is exactly what the Board did.
 Nichia’s petition asserted five different grounds of un-
 patentability. Decision, at *2. For each ground, Nichia re-
 lied on a prior art reference’s disclosure of a single planar
 surface as teaching the claimed mounting surface. See J.A.
 137–41 (Kim), J.A. 157–60 (Adachi), J.A. 170–73 (Naga-
 yama), J.A. 181–84 (Okazaki). Nichia also relied on Figure
 4A of the ’040 patent to demonstrate the prior art refer-
 ences teach the claimed mounting surface. Decision, at *6–
 9. To resolve this matter, the Board only needed to deter-
 mine whether the claimed mounting surface encompassed
 a single planar surface. See Decision, at *6–9; see also J.A.
 1287 (Board explaining it need not “determine . . . the pre-
 cise relationship between the recited ‘mounting surface’
 and the contacts”). As discussed above, the Board properly
 concluded it does not.
     Second, we have held the Board can render prior art
 patentability determinations even if claims are indefinite.
 Samsung Elecs. Am. Inc. v. Priusa Eng’g Corp., 948 F.3d
 1342, 1355 (Fed. Cir. 2020) (explaining indefiniteness does
 not “necessarily preclude the Board from addressing pa-
 tentability” on other grounds). In Intel Corp. v. Qualcomm
 Inc., we explained “indefiniteness of a limitation . . . pre-
 cludes a patentability determination only when the indefi-
 niteness renders it logically impossible for the Board to
 reach such a decision.” 21 F.4th 801, 813 (Fed. Cir. 2021)
 (emphasis added). We further explained that “it is not al-
 ways impossible to adjudicate a prior-art challenge” be-
 cause of alleged indefiniteness of one limitation. Id. Here,
 the Board properly rendered a patentability determination
 because it did not conclude such determination was logi-
 cally impossible based on any alleged indefiniteness.
     The Board proceeded exactly as our case law pre-
 scribes—deciding only the issues necessary to resolve the
 dispute before it. See Nidec Motor Corp. v. Zhongshan
 Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir.
 2017) (affirming the Board’s decision not to construe the
Case: 22-1704    Document: 47      Page: 7   Filed: 11/02/2023

 NICHIA CORPORATION v. DSS, INC.                           7

 preamble because it was not material to the dispute). The
 Board was not required to reach Nichia’s arguments about
 any alleged indefiniteness because its construction was
 sufficient to apply the asserted prior art in this dispute.
 The Board was also correct in rendering its patentability
 determination because it was not impossible to do so. We
 affirm the Board’s construction of “mounting surface” and
 its final written decision on patentability.
                        CONCLUSION
     For the reasons given, we affirm the Board’s conclusion
 that Nichia did not meet its burden to show claims 1–4, 8,
 and 11 are unpatentable.
