Appeal No. 2006-1065 Application No. 10/296,231 We consider first the examiner’s rejection under § 112, first paragraph, description requirement. We agree with the examiner that the original specification fails to provide descriptive support for the claim recitation “the particulate hydrophobic polymers contain no active substance entrapped therein, distributed throughout, absorbed or adsorbed.” As appreciated by appellants, whether the claim recitation has original descriptive support in the specification is a question of fact. In the present case, we are in agreement with the examiner that the facts do not support appellants’ contention that they had possession, at the time of filing the present application, of the concept that the claimed polymers contain no active substance entrapped therein, distributed throughout, absorbed or adsorbed. In re Anderson, 471 F.2d 1237, 1244, 176 USPQ 331, 336 (CCPA 1973). Our review of the original specification finds no indication that appellants reasonably conveyed to one of ordinary skill in the art that they possessed the inventive concept that the disclosed polymers have no association with active substances. Appellants rely upon the citation of U.S. Patent No. 5,476,660 at page 1 of the present specification, lines 35-42 for evidence that they consider their polymers to be different from the carrier particles of the cited patent. However, the specification reference to U.S. Patent No. 5,476,660 simply describes the prior art use of polymeric retention agents having active substances embedded therein, but the specification provides absolutely no disclosure that the present invention involves a departure from using the polymeric particles as carrier particles. Indeed, it is just as, if not more so, reasonable to conclude that the polymeric particles of the present invention are intended to be employed as such carrier particles. 3Page: Previous 1 2 3 4 5 6 NextLast modified: November 3, 2007
