Appeal No. 2006-0180 Παγε 3 Application No. 10/369,343 OPINION In reaching our decision in this appeal, we have given careful consideration to the appellant's specification and claims, to the applied prior art references, and to the respective positions articulated by the appellant and the examiner. As a consequence of our review, we make the determinations which follow. Claim Interpretation A central issue in dispute in this appeal is whether the operating room having an operating table is positively recited in independent claims 1 and 2. The preamble of each of these claims recites apparatus "for use in an operating room with a structural ceiling and having an operating table located therein" (emphasis added). If we stopped reading the claim at this point, we might infer that the operating room is not positively recited as part of the invention but, rather, is the intended environment of use for the claimed apparatus. Claims 1 and 2 go on, however, to recite "a set of primary rails connected to the operating room [or to the ceiling of the operating room]." The preamble of a claim does not limit the scope of the claim when it merely states a purpose or intended use of the invention; however, terms appearing in a preamble may be deemed limitations of a claim when they give meaning to the claim and properly define the invention. See In re Paulsen, 30 F.3d 1475, 1479, 31 USPQ2d 1671, 1673 (Fed. Cir. 1994).
