Appeal No. 98-1316 Application No. 08/420,896 434 U.S. 1238 (1978). With respect to the description requirement, the court in Vas-Cath, Inc. v. Mahurkar at 935 F.2d 1563-64, 19 USPQ2d 1117 stated: 35 U.S.C. § 112, first paragraph, requires a "written description of the invention" which is separate and distinct from the enablement requirement. The purpose of the "written description" requirement is broader than to merely explain how to "make and use"; the applicant must also convey with reasonable clarity to those skilled in the art that, as of the filing date sought, he or she was in possession of the invention. The invention is, for purposes of the "written description" inquiry, whatever is now claimed. . . . drawings alone may be sufficient to provide the "written description of the invention" required by § 112, first paragraph. With these authorities in mind, we have carefully reviewed the original disclosure and fail to find descriptive support for the recitation in independent claims 21 and 22 that the fluid catheter has "a second end directly connected to a dialysate reservoir container [i.e, element 28]." Contrary to such an arrangement, the specification expressly states that the: Fluid line 34 terminates at a catheter (not shown) that is in fluid communication with the peritoneal cavity of the patient 26.
