DECISION ON APPEAL This is an appeal under 35 U.S.C. § 134(a) involving claims to a handheld law maintenance tool, which have been rejected as anticipated and/or obvious. We have jurisdiction under 35 U.S.C. § 6(b). We affirm in part. 1 We use the word “Appellant” to refer to “applicant” as defined in 37 C.F.R. § 1.42. Appellant identifies the real party in interest as MTD Products Inc. (Appeal Br. 2.) We note that neither the Appeal Brief nor the Reply Brief is paginated. The page numbers we refer to of these documents are based on assigning the first page of the document as page 1, and the remaining pages as if numbered consecutively. Appeal 2020-000956 Application 15/010,662 2 STATEMENT OF THE CASE Appellant’s Specification notes that handheld lawn maintenance tools that have a single power head that can be used with multiple different attachments “have become increasingly popular among homeowners.” (Spec. ¶ 3.) Appellant’s invention is directed to such a handheld lawn maintenance tool. (Id. ¶ 2.) Claims 1–3, 6, and 10–24 are on appeal. Claims 1 and 12 are illustrative and read as follows: 1. A handheld lawn maintenance tool comprising a power head having a power source connected to a rear end of a housing, said housing including a first handle oriented along a longitudinal axis of said power head, a second handle extending from said housing adjacent to a forward end of said housing, a control mechanism positioned adjacent to said first handle, a power generator located within said housing and operatively connected to said power source, and a first attachment mechanism includes a recess for receiving a releasably attachable working attachment or an adapter, wherein said power generator is positioned between said first handle and said second handle, said power generator generates an output source of power. (Appeal Br. 20 (Claims Appendix) (paragraphing added).) Appeal 2020-000956 Application 15/010,662 3 12. A handheld lawn maintenance tool comprising: a power head having a power source releasably attached thereto, said power head including a power generator electrically connected to said power source for generating output power, a first attachment mechanism operatively connected to said power generator, a trigger operatively connected to said power generator for selectively controlling said output power from said power generator, a first handle and a second handle, wherein said power generator is positioned between said first and second handles, and said second handle being rotatable in a fore/aft manner; an adapter releasably attached to said first attachment mechanism of said power head, said adapter receiving said output power from said power generator; and a working attachment releasably attached to said adapter, wherein said adapter transfers said output source of power from said power generator to said working attachment. (Appeal Br. 21 (some paragraphing added).) The prior art relied upon by the Examiner is: Name Reference Date Motosko US 6,955,227 B1 Oct. 18, 2005 Lidstone US 3,129,771 Apr. 21, 1964 Yamada et al. US 2013/0075122 A1 Mar. 28, 2013 Ryobi, 40V-X EXPAND-IT STRING TRIMMER Appeal 2020-000956 Application 15/010,662 4 The following grounds of rejection by the Examiner are before us on review: Claims 1–3, 6, 11–15, 18, 19, 21, and 23 under 35 U.S.C. § 102(a) as anticipated by Motosko.2 Claims 1–3, 6, 10–17, 19, 21, 23, and 24 under 35 U.S.C. § 102(a) as anticipated by Ryobi.3 Claims 10, 16, 17, and 24 under 35 U.S.C. § 103(a) as unpatentable over Motosko and Lidstone Claims 18, 20, and 22 under 35 U.S.C. § 103 (a) as unpatentable over Ryobi and Yamada. DISCUSSION I Anticipation 1. Motosko a. Claim 1 The Examiner relies on Figure 1 of Motosko to conclude that the invention of claim 1 is anticipated. Figure 1 is reproduced below. 2 The Examiner’s rejection includes claim 5. However, claim 5 was cancelled and is not on appeal. 3 The Examiner’s rejection includes claim 5. However, claim 5 was cancelled and is not on appeal. Appeal 2020-000956 Application 15/010,662 5 Figure 1 depicted above shows an embodiment of a hand held power gardening tool. The Examiner identifies element 35 as the power head with a power generator inside, and element 38 as the power source connected to a rear end of a housing. (Final Action 4.) The Examiner identifies a first handle as the element adjacent the trigger/control mechanism 48. (Id.) The second handle extending from the housing is identified by the Examiner as element 42. (Id.) Element 30 is identified by the Examiner as meeting the first attachment mechanism that includes a recess for receiving a releasably attachable working attachment. (Id.) We agree with the Examiner’s findings and conclusion of anticipation. We first provide our construction of certain terms: “rear end of a housing,” “forward end of said housing,” and “longitudinal axis of said power head.” Appeal 2020-000956 Application 15/010,662 6 “[D]uring examination proceedings, claims are given their broadest reasonable interpretation consistent with the specification.” In re Hyatt, 211 F.3d 1367, 1372 (Fed. Cir. 2000). We first look to the Specification “to see if it provides a definition for claim terms, but otherwise apply a broad interpretation.” In re ICON Health and Fitness, Inc., 496 F.3d 1374, 1379 (Fed. Cir. 2007). “[W]hile it is true that claims are to be interpreted in light of the specification . . . , it does not follow that limitations from the specification may be read into the claims . . . . [T]he claims define the invention.” Sjolund v. Musland, 847 F.2d 1573, 1581–82 (Fed. Cir. 1988). Appellant’s Specification does not provide any explicit definitions. Nor do we find any particular guidance in the Specification suggestive of an intent to define these terms in a particular manner. Bell Atlantic Network Servs., Inc. v. Covad Communications Grp, Inc., 262 F.3d 1258, 1268 (Fed. Cir. 2001) (“[A] claim term may be clearly redefined without an explicit statement of redefinition.”). A power head is referred to in figures of the prior art and embodiments of the invention as a particular part identified by a drawing reference number that can be held in some manner and receives a component to provide power. (See, e.g., Spec. ¶¶ 5, 8, 26, 27.) A housing is referred to in figures of embodiments of the invention as a structure that other elements reside within or are attached to. (See, e.g., Spec. ¶¶ 27, 31.) Each of the noted terms “rear end of,” “forward end of,” and “longitudinal axis of” rest upon an arbitrary frame of reference. A rear end is associated with being the back end of an object, but that only has relevance with respect to what is designated the front or forward end of an object. The forward/front end of an object can be the part that is seen first Appeal 2020-000956 Application 15/010,662 7 when the object is presented for use or view. A front or forward end can also be a top end, and the rear end can also be a bottom. In this case, the object at issue with respect to the term front and rear end is a housing for the power head of a hand held tool. The forward end of such an object could be the portion to which a working attachment is provided or it could simply be the top of the housing. A rear end would be a position that is opposite either the working attachment end or opposite the top of the housing. A longitudinal axis is a coordinate axis along a lengthwise or horizontal direction with respect to any particular object. With respect to the object at issue here, a longitudinal axis refers to a lengthwise direction of the power head. In light of the foregoing constructions, we note that the power source 38 in Figure 1 of Motosko can reasonably be found to be connected to a rear end of a housing because it is located opposite a top side of a housing—i.e., a structure to which other elements are attached or other elements reside within. The second handle 42 is adjacent to a forward end of the housing, e.g., the top side of the housing. Furthermore, the first handle located to the left of the power source in Figure 1 is oriented along a longitudinal axis of the power head, which power head is shaped like the number seven, and so has both horizontal and vertical segment lengths. We also agree with the Examiner that the power generator is positioned between the first handle and the second handle. That is, the power generator is in the space separating the first handle and the region of the intersection of the second handle with the housing. Appeal 2020-000956 Application 15/010,662 8 Appellant’s primary disagreement with the Examiner’s rejection rests on the construction of the term “rear end.” (Appeal Br. 9–10; Reply Br. 4– 5.) According to Appellant, two passages of the Specification (¶¶ 27–28) “clearly indicate that the ‘rear end’ of the power head is the rear distal end of the power head.” (Appeal Br. 9.) We do not find Appellant’s argument persuasive as to the construction of the phrase “rear end of a housing.” It is true that the Specification indicates, with respect to Figure 3, reproduced below, that the “power source 48 is located at the rear of the power head 42” and the “[t]he first handle 50 is positioned adjacent to the rear of the power head 42.” Figure 3 above shows “an embodiment” of the claimed “power head.” (Spec. ¶ 15.) The power source 48 is located rearward of the first handle 50 and the first attachment mechanism 60. We note that rear is determined with respect to a reference object of the power source. One could just as easily define the power source as being at the bottom end of the power head. Moreover, as Figure 3 is simply “an embodiment” of the power head of the invention (Spec. ¶¶ 27–28), it does not serve to define the phrase “rear end of a housing” or the only possible shape of a power head. Thus, we also disagree with Appellant that our construction above is “beyond the broadest reasonable construction in view of the Specification as it would be understood by one having ordinary skill in the art” (Reply Br. 3). Appeal 2020-000956 Application 15/010,662 9 Appellant’s further argument rests on a conclusion that there is only a single orientation of an object by which one can establish a rear end, which precludes a bottom of an object from also being a rear end. (Appeal Br. 10– 11.) In particular, according to the Appellant “[o]ne skilled in the art would properly understand the orientation of the housing of Motosko as shown in the following annotated drawing:” . (Id.) The above drawing is an annotated depiction of a partial view of Figure 1 of Motosko. Appellant does not identify any persuasive evidence supporting its assertion that this is the only possible interpretation of the rear end of Motosko. Icon Health & Fitness, Inc. v. Strava, Inc., 849 F.3d 1034, 1043 (Fed. Cir. 2017) (“Attorney argument is not evidence.”). Although it might be one interpretation, for the reasons discussed above, we disagree with Appellant that the position labeled as bottom in the annotated figure cannot also be considered a rear end of the power head of Motosko, where the front end would be the “top” of the power head in the depiction above. Thus, we do not find Appellant’s argument that “Motosko fails to teach a power source connected to a rear end of a housing” (Appeal Br. 8) persuasive. In light of the foregoing, we affirm the Examiner’s rejection of claim 1 as being anticipated by Motosko. Appeal 2020-000956 Application 15/010,662 10 Claims 2, 3, 6, 11, 21, and 23, which depend from claim 1, have not been argued separately and therefore fall with claim 1. 37 C.F.R. § 41.37(c)(1)(iv). b. Claim 12 Like claim 1, claim 12 requires the power head to have a power source and first and second handles. However, claim 12 does not have the same positional requirements as claim 1 with regard to the power source and the first handle. On the other hand, claim 12 requires that the second handle is “rotatable in a fore/aft manner.” The Examiner finds that this limitation is met because second handle 42 of Figure 1 can be rotated with respect to attachment mechanism 40 and can rotate parts 25, 27, and 28. (Final Action 6.) According to the Examiner, it is well known by those of ordinary skill in the art of hand drills, and by those who have used hand drills, that a stabilizer handle such as 42 of Motosko rotates relative to the working attachment of the drill when the drill is being powered and that such a stabilizer handle is used to rotate and move the working attachment through a fixed connection when the working attachment becomes stuck or needs to be otherwise moved. (Ans. 20.) We do not agree with the Examiner’s findings and conclusion of anticipation as to claim 12. In particular, claim 12 requires that the second handle itself is rotatable in a fore/aft manner. There is nothing in Motosko to indicate that the stabilizing handle 42 is rotatable, and the Examiner’s position in the Answer that the handle rotates “relative to the working attachment” or that the handle is used to rotate the attachment does not establish rotatability of the handle itself in a fore/aft manner. Appeal 2020-000956 Application 15/010,662 11 For this reason we do not affirm the Examiner’s rejection of claims 12–15, 18, and 19 as being anticipated by Motosko. 2. Ryobi The Examiner finds that Ryobi discloses the invention recited in independent claims 1, 12, and 24 based on the following annotated picture from the depicted handheld lawn maintenance tool of Ryobi. The annotated figure above depicts the power handle portion of the Ryobi lawn trimmer. a. Claim 1 Claim 1 requires that the “second handle extend[] from said housing adjacent to a forward end of said housing.” The Examiner notes that “Housing” is taken to mean “something that cover[s], protects, or supports.” (See Webster’s II Dictionary, Third Edition, p. 348.) (Ans. 21.) The Examiner determines further that a housing is not required by the Specification to be a unitary structure, nor is that required by the claim. (Id.) Appellant argues that the shaft to which the second handle of Ryobi is attached is not part of the housing, but rather “is an intermediate component Appeal 2020-000956 Application 15/010,662 12 positioned between the housing and the second handle of Ryobi.” (Appeal Br. 13.) Appellant notes “[t]he housing of the power head in Ryobi appears to be plastic and the shaft appears to be metal” (id. at 14) and that “the shaft is a separate component than the housing” (id. at 15) that is “removably connectable to the housing” (id. at 13). The dispute turns on the construction of the term “housing.” We touched on that term briefly above. We agree with the Examiner that a housing is not required, by the claim language or the Specification, or the prior art, to be a unitary structure, and that functionally, a housing can provide cover, protection and/or support. However, in providing support, a housing still provides a frame around that which is to be supported. See, e.g., “Housing,” Miriam-Webster’s Collegiate Dictionary 11th edition, (2009) (“3. . . c: a support (as a frame) for mechanical parts”). The shaft to which the Ryobi second handle is connected and on which it rests, does not provide a frame for the second handle which it supports, though it certainly provides support. Thus, we agree with Appellant that the shaft from which the Ryobi second handle extends would not be considered by one of ordinary skill in the art to be part of a housing. Consequently, we do not affirm the Examiner’s rejection that claim 1 or claims 2, 3, 6, 10, 11, 21, and 23, which depend therefrom, are anticipated by Ryobi. b. Claims 12 and 24 Unlike claim 1, claim 12 does not require a housing, but requires the “power head” to have “a first handle and a second handle.” Similarly claim 24 requires the “power head” to have “a first handle . . . a second handle.” According to the Examiner, the upper part of the Ryobi tool that Appeal 2020-000956 Application 15/010,662 13 includes a power generator is the power head, and that the shaft and second handle are “capable of being considered parts of the power head.” (Ans. 22.) Appellant argues that the shaft to which the handle of Ryobi is attached is not part of the power head. (Appeal Br. 15 (“[T]he handle of Ryobi is a separate component, which is attached to a shaft that is releasably connectable to the power head.”); Reply Br. 10 (“Ryobi actually does not teach that the second handle and shaft are capable of being part of the power head . . . .” (emphasis omitted)).) This dispute turns on the construction of the term “power head” and in this case, we determine that the Examiner has the better position. We touched on the term power head briefly above in addressing the rejection over Motosko. As we noted, there is not an explicit definition for this term. Nor does Appellant argue that this is a term of art with a well-known definition. Rather, Appellant contends that “the Specification of the present application clearly teaches that the shaft (of the adapter) is separate and distinct from the housing.” (Reply Br. 10.) Whether or not the shaft of the adapter depicted in the Specification is separate and distinct “from the housing” is not relevant to the construction of the term “power head.” “[C]laim construction must begin with the words of the claims themselves.” Amgen Inc. v. Hoechst Marion Roussel, Inc., 457 F.3d 1293, 1301 (Fed. Cir. 2006). Appellant’s claims 12 and 24, relevant to the dispute here, require the power head to have two handles and an attachment mechanism. Figure 3 of Appellant’s Specification, provides “an embodiment of a power head” of the claimed invention. (Spec. ¶ 15.) The figure, which is reproduced above in our discussion of the anticipation rejection over Motosko, shows a power head identified as the entire Appeal 2020-000956 Application 15/010,662 14 structure 42, that includes, inter alia, a power source 48, a first attachment mechanism 60, a first handle 50, and a second handle 54. (Spec. ¶ 27.) However, Figure 3 does not confine the claims to only that configuration of a power head; it is simply one example. See Innova/Pure Water, Inc. v. Safari Water Filtration Sys., Inc., 381 F.3d 1111, 1117 (Fed. Cir. 2004) (“particular embodiments appearing in the written description will not be used to limit claim language that has broader effect” where there is no “clear intention to limit the claim scope using ‘words or expressions of manifest exclusion or restriction’”). Thus, the fact that the first attachment mechanism is not a “shaft” and the second handle is not shown attached to a shaft (Appeal Br. 15; Reply Br. 10) is not controlling as to what one of ordinary skill in the art would understand to be within the scope of the claimed power head. We do not find anything in the Specification that demonstrates an intention to exclude second handles attached to the attachment mechanism from being within the scope of the claimed power head. Moreover, we do not find anything in the Specification that demonstrates an intention to exclude elements from a power head when they are releasably attached. Indeed, the Specification states that a power head “includes a power source” and that the power source “is removably attachable to the housing,” Where the “housing” is a part of the power head 42. (Spec. ¶ 27 and Fig. 3.) Thus, we conclude that whether a handle is permanently attached to the power head is not determinative of whether the handle can be considered part of the power head. Stated in the affirmative, we conclude that a removably attachable handle can still be considered to be part of a power head just as a power source that is Appeal 2020-000956 Application 15/010,662 15 removably attachable is considered by Appellant’s Specification to be a part of a power head. We do not find Appellant’s argument that “nowhere in the Ryobi reference is there an explanation or description that the second handle is part of the power head” (Reply Br. 10) to be persuasive that Ryobi does not anticipate claim 12. The second handle of Ryobi is attachable to a shaft that is described in Ryobi as being “the bottom shaft of the RYOBI 40 X String Trimmer power head.” (Ryobi at 1 (emphasis added).) Thus, we conclude that the shaft is part of the power head and, in light of our claim construction above, the removably attachable handle is properly considered to be part of the Ryobi power head when it is attached. Consequently, we affirm the Examiner’s rejection that claims 12 and 24 are anticipated by Ryobi. Claims 13–17, and 19, which depend from claim 12 have not been argued separately and therefore fall with claim 12. 37 C.F.R. § 41.37(c)(1)(iv). II Obviousness 1. Motosko and Lidstone a. Claim 10 Appellant argues only that Lidstone does not cure the deficiency of Motosko regarding a power source connected to the rear end of the housing. (Appeal Br. 16–17.) However, because we find that Motosko describes a power source connected to the rear end of a housing, we affirm the Examiner’s rejection that claim 10 is rendered obvious from the teachings of Motosko and Lidstone. Appeal 2020-000956 Application 15/010,662 16 b. Claims 16, 17, and 24 Claim 24, like claim 12 requires that the second handle is “rotatable in a fore/aft manner.” Lidstone is not relied upon by the Examiner for such a teaching. (See, e.g., Final Action 13.) We reverse the Examiner’s rejection of claims 16, 17, and 24 as being rendered obvious from the teachings of Motosko and Lidstone because, as discussed above, Motosko does not teach a second handle that is “rotatable in a fore/aft manner” as required by claims 12 and 24 2. Ryobi and Yamada a. Claim 22 Claim 22 depends from claim 1 and thus includes the requirement that the second handle extends from the housing. As we explained above, we do not agree with the Examiner that Ryobi teaches a handle extending from a housing. The Examiner does not rely on Yamada for such a teaching. (See, e.g., Final Action 17.) Thus, we reverse the Examiner’s rejection of claim 22 as being obvious from Ryobi and Yamada. b. Claims 18 and 20 Appellant argues only that Yamada does not cure the deficiency regarding Ryobi of a power head having a second handle. (Appeal Br. 18.) However, because we find that Ryobi describes a power head having a second handle, we affirm the Examiner’s rejection of claims 18 and 20 as being obvious from the teachings of Ryobi and Yamada Appeal 2020-000956 Application 15/010,662 17 DECISION SUMMARY In summary: Claims Rejected 35 U.S.C. § Reference(s)/Basis Affirmed Reversed 1–3, 6, 11– 15, 18, 19, 21, 23 102 Motosko 1–3, 6, 11, 21, 23 12–15, 18, 19 1–3, 6, 10– 17, 19, 21, 23, 24 102 Ryobi 12–17, 19, 24 1–3, 6, 10, 11, 21, 23 10, 16, 17, 24 103 Motosko, Lidstone 10 16, 17, 24 18, 20, 22 103 Ryobi, Yamada 18, 20 22 Overall Outcome 1–3, 6, 10– 21, 23, 24 22 TIME PERIOD FOR RESPONSE No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a).
