Opinion

REYNA, Circuit Judge.

Steven Chudik appeals from the Patent Trial and Appeal Board’s (“Board”) determination that claims 1,15,18, and 33-40 of U.S. Patent Application 11/525,631 (“’631 application”) are anticipated by two prior art references. Because substantial evidence does not support the Board’s determination, we reverse.

Background

1. The ’631 Application

The ’631 application, entitled “Glenoid Implant for Minimally Invasive Shoulder Replacement Surgery,” describes an invention related to “rotator cuff sparing procedures and associated devices for shoulder replacement surgery.” J.A. 24, ¶ 2. The ’631 application improves on the prior art by offering “simple and less invasive perpendicular access to the humeral and glenoid joint surfaces,” which “spares the rotator cuff tendons and allows for a quicker and more functional recovery.” J.A. 29-30, ¶¶ 12-13. As relevant here, the surgery described in the ’631 application involves two main steps.. First, the surgeon removes “a minimal amount of bone from the peripheral surface of the glenoid” — a process called reaming. See J.A. 51, ¶ 124. Second, the surgeon places an implant in the- reamed cavity. See J.A. 57, ¶ 142. The glenoid, reamer, and implant are pictured below:

*1368 [[Image here]]

J.A. 79, 91, 94. The scapula is the shoulder bone connecting the humeras (upper arm bone) to the clavicle (the collar bone). Figure 7a shows that the glenoid cavity 22 faces outward on the scapula. Figure 21 depicts a side view of the reamer, and Figure 22 shows how the reaming surface 114 faces toward the glenoid cavity. J.A. 30, ¶ 17; J.A. 37, ¶ 80.

Once the glenoid cavity has been reamed, the implant’s protruding surface 119 “sits within the concavity of the reamed glenoid surface.” J.A. 57, ¶ 142. Figures 23a and 27a show the protruding surface 119, which “protrudes into the gle-noid 22 to a specified depth.” Id. The ’631 application describes the reaming surface 114 in similar terms to the protruding surface 119. Com/pare J.A. 51, ¶ 124, with J.A. 57, ¶ 142. Like the reaming surface 114, the protruding surface 119 faces toward the glenoid cavity. See Fig. 22.

Representative independent claims 1 and 40 are at issue in this appeal. 1 They recite:

1. A glenoid implant comprising:
a shell having a protruding surface on a first side arranged to engage the surface of a cavity formed in a gle-noid extending between peripheral glenoid surfaces, and
a flat surface on the first side adjacent the protruding surface arranged to engage the peripheral glenoid surfaces adjacent the cavity, and
a wear-resistant articulating surface on a second side opposite the flat surface and the protruding surface.

*1369 40. A glenoid implant comprising:

a protruding surface on a first side arranged to engage the surface of a cavity formed in a glenoid extending between peripheral glenoid surfaces, and a substantially planar wear-resistant articulating surface on a second side opposite the protruding surface.

J.A. 3 (disputed term emphasized).

2. Prior Art

Rambert

FR 2 579 454 (Oct. 3, 1986) (“Rambert”) discloses a glenoid implant with a shell element. J.A. 188.

[[Image here]]

Rambert Figure 2 shows element 27b in contact with anchoring element 27a, which in turn contacts the glenoid cavity. J.A. 198.

Bouttens

WO 01/47442 A1 (July 5, 2001) (“Bout-tens”) discloses a shoulder prosthesis assembly for implantation in the glenoid. J.A. 199.

*1370 [[Image here]]

Bouttens Figure 1 shows the protruding surface 11 facing away from the glenoid cavity and toward the humerus. J.A. 210. It also shows screws on the opposite side of the protruding surface attaching the implant to the glenoid region. See id.

3. Examination Proceedings

Mr. Chudik filed the ’631 application on September 25, 2006. On June 5, 2012, the Examiner issued a Final Action rejecting claims 1, 15, 18, and 33-40. The Examiner made four rejections:

• Claim 40 rejected under 35 U.S.C. § 112, first paragraph 2 ;
• Claims 1, 15, and 33-39 rejected under 35 U.S.C. § 102(b) as anticipated by Rambert;
• Claim 40 rejected under 35 U.S.C. § 102(b) as anticipated by Bouttens;
• Claim 18 rejected under 35 U.S.C. § 103(a) as obvious over Rambert and Church.

Mr. Chudik filed a Notice of Appeal of the Examiner’s rejections on September 1, 2012.

*1371 4. Board Proceedings

The parties briefed Mr. Chudik’s appeal in 2012 and 2013. The Board issued its Decision on Appeal on February 10, 2016. It did not sustain the Examiner’s determination that claim 40 failed to comply with § 112, first paragraph. But it did sustain the Examiner’s determinations that:

• Claims 1,15, and 33-39 were anticipated by Rambert;
• Claim 40 was anticipated by Bouttens;
• Claim 18 would have been obvious over Rambert and Church.

In support of its findings, the Board stated that “independent claim 1 is an apparatus claim and does not require the recited surfaces to ‘engage’ the specified glenoid regions; rather, independent claim 1 requires only that the recited surfaces be ‘arranged’ for such engagement.” J.A. 6. Therefore, according to the Board, “the fact that Rambert’s protruding and flat surfaces are not described or depicted as actually engaging the specified glenoid regions is not dispositive, as they can still be arranged to do so.” Id. The Board thus sustained the Examiner’s rejection of claims 1, 15, and 33-39 based on Rambert.
