Appeal from the United States Patent and Trademark Office, Patent Trial and Appeal Board in No. 95/001,754. ______________________

Decided: March 11, 2022 ______________________

ROBERT GREENSPOON, Dunlap Bennett & Ludwig PLLC, Chicago, IL, for appellant Eugene H. Luoma. ______________________

Before MOORE, Chief Judge, CHEN and HUGHES, Circuit Judges. PER CURIAM. Eugene H. Luoma appeals from an inter partes reex- amination decision of the Patent Trial and Appeal Board that affirmed an examiner’s rejection of claims 1, 2, 4–8, 10, and 11 of U.S. Patent No. 6,775,873. GT Water Prods., Inc. v. Luoma, No. 2015-003755, 2015 WL 4552062 (P.T.A.B. July 27, 2015) (Board Decision). The Board found Case: 19-2315 Document: 50 Page: 2 Filed: 03/11/2022

2 IN RE: LUOMA

that Hymes 1 anticipated claims 1, 2, 4, 6–8, and 11 and held that claims 5 and 10 would have been obvious over that same reference. For the following reasons, we affirm. I The ’873 patent relates to “an apparatus for removing hair from a drain[.]” ’873 patent at 1:8–9. Claim 1 is rep- resentative for purposes of this appeal: 1. Apparatus for removing hair from a drain, com- prising: (a) an elongate, flexible strip; (b) the elongate, flexible strip having a plu- rality of barbed portions, the barbed por- tions being adapted to grip hair in the drain, wherein the barbed portions are ori- ented at an acute angle to the axis of the elongate strip, wherein the vertex of the angle points away from the handle; and (c) a handle, wherein the handle is a dis- tinct structural element from the elongate, flexible strip. (emphasis added to handle limitation). A passage in the written description describes an embodiment of the claimed handle: A handle 22 is attached to the flexible strip 12 at the proximal end 14. Preferably, the handle 22 is integrally molded with the strip 12. The handle may have an aperture 24 therethrough to allow the handle to be gripped by a person’s fingers, as best seen in FIGS. 3 and 4.

IN RE: LUOMA 3

Operation of the device is shown in FIGS. 3, 4, and 5. Turning to FIG. 3, a person grips the device 10 by its handle 22, preferably by inserting a finger through the aperture 24. The device 10 is then in- serted into the drain D, with the distal end 16 lead- ing, as shown by the arrow in FIG. 3. Id. at 2:12–21. That description references figure 3, which provides a helpful visual:

II Luoma first argues the Board adopted an unreasonably broad construction of the handle limitation. He distin- guishes a handle—something “designed or made specifi- cally to be held, grasped, or operated by a hand”—from something that is handleable. See, e.g., Appellant’s Br. 9. And he faults the Board for not limiting the claimed handle according to this distinction. We do not agree. The broadest reasonable interpretation of the handle limitation does not require any particular structure or de- sign purpose. See In re Rambus, Inc., 753 F.3d 1253, 1255 (Fed. Cir. 2014) (In inter partes reexamination proceedings, claims are given their “broadest reasonable interpretation consistent with the specification.”).

4 IN RE: LUOMA

language or written description requires the handle have some structural feature specifically designed for holding— like a finger depression, an aperture, or a knob. Contra Appellant’s Br. 10 (arguing Hymes lacks such structure). The written description has no redefinition of the word handle, nor does it contain a disavowal of claim scope. The handle is simply the portion of the apparatus that a user grips. See ’873 patent at 2:12–21. Certainly, the handle must be structurally distinct from the elongate, flexible strip. Id. at claim 1. But that does not limit the claimed handle to a particular design. Accordingly, we agree with the Board’s construction. See Board Decision at *7 (con- struing “a handle” to mean the portion held by the user that is distinct from the elongate, flexible strip). Applying this construction, substantial evidence sup- ports the Board’s finding that Hymes teaches the claimed handle. See Vicor Corp. v. SynQor, Inc., 869 F.3d 1309, 1320 (Fed. Cir. 2017) (reviewing findings in an inter partes reexamination for substantial evidence). Hymes’ sewer opener “consists of a number of concentric coils [B] com- posed of a continuous strip of spring-steel properly tem- pered so as to readily conform to the change required in practical use.” Hymes ll. 17–21. Those concentric coils B “may by drawn out longitudinally,” id. ll. 30–31, and “can be manipulated in a small space by being uncoiled as it is inserted in the passage to be opened,” id. ll. 60–62 (empha- sis added). Also, those coils are described as distinct from another structural element of the sewer opener, the work- ing end. That working end has a spear point C and several barbs D: Case: 19-2315 Document: 50 Page: 5 Filed: 03/11/2022

IN RE: LUOMA 5

Id. Fig. 1; see also id. ll. 36–45. Based on this disclosure, the Board found Hymes taught a structure held by the user and distinct from the elongate, flexible strip (i.e., the work- ing end). See Board Decision at *7. And we cannot say that finding is unsupported by substantial evidence. III Luoma also argues that substantial evidence does not support the Board’s finding that Hymes’ working end is an “elongate, flexible strip.” He claims that end is “short, straight, unbent, [and] inflexible.” Appellant’s Br. 3. But there is no indication in this record that Luoma presented that argument below. See Board Decision at 5 (summariz- ing Luoma’s arguments). So it is not clear whether Luoma has preserved this argument. See, e.g., Cal. Ridge Wind Energy LLC v. United States, 959 F.3d 1345, 1351 (Fed. Cir. 2020) (“We may deem an argument forfeited when a party raises it for the first time on appeal.”). Even so, we do not agree with Luoma on the merits. Substantial evidence supports the Board’s finding that the working end in Hymes is elongate and flexible. Hymes repeatedly describes embodiments of its sewer opener as “composed of a strip of tempered spring-steel” or “composed of a continuous strip of spring[ ]steel.” E.g., Hymes ll. 18– 19, 27–28 (emphases added). This suggests the sewer opener has the same spring-like properties throughout, in- cluding at the working end. Hymes further describes how the opener’s continuous, spring-steel form allows it to “be[] uncoiled as it is inserted in the passage to be opened, and when withdrawn the resilience is so great as to automati- cally return to the coiled position.” Id. ll. 58–64. This also supports a finding that the working end is flexible. And Case: 19-2315 Document: 50 Page: 6 Filed: 03/11/2022

6 IN RE: LUOMA

the working end of Hymes is depicted in the figures as elon- gate:

Id. Fig. 3. In light of this evidence, we cannot say the Board’s findings were unsupported. IV Based on the foregoing, we hold the Board correctly construed the claimed handle. And under that construc- tion, substantial evidence supports the Board’s finding that Hymes teaches that handle. Likewise, substantial evi- dence supports the Board’s finding that Hymes teaches an elongate, flexible strip. Accordingly, we affirm. AFFIRMED COSTS No costs.
