Appeal No. 2003-0580 Application No. 09/139,081 Second, Wilson does not establish, such as by providing evidence from carpet users, that the claimed invention solves any need. Wilson merely submits articles by trade journal publishers who are in a position to receive advertising revenue from companies whose products they discuss and who, therefore, cannot reasonably be considered impartial. Not surprisingly, the articles praise the products made by BASF (the appellants’ assignee) and every other company mentioned in the articles. Moreover, the articles clearly do not establish that the appellants have solved the need for stain resistant, ozone fade resistant carpet fibers such that no further improvement in carpet fiber stain resistance and ozone fastness is needed. Third, Wilson does not establish that the stain resistance and ozone fastness which the articles attribute to the Savant™ fibers are due to the characteristics set forth in the appellants’ claims. For the above reasons we conclude that a prima facie case of obviousness of the appellants’ claimed invention has been established and has not been effectively rebutted by the appellants.5 5 A discussion of Chambers, Ida ‘973 and Ida ‘901 is not necessary to our decision. 8Page: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 3, 2007
