Description
This is an appeal from the dismissal of an action by appellants, Bolkcom and Knapp, for infringement of a combination patent protecting the invention of a novel plant for the manufacture of silicon carbide. The patent in suit is Patent Re. 27,018 (hereinafter Patent 018) dated January 5, 1971, a reissue of Patent No. 3,432,605 (hereinafter Patent 605), dated March 11, 1969. The district court held that claims 11-14, which were added by the reissue, were invalid because they were an unauthorized enlargement of the disclosures of the original patent. It also held that the claims that were carried over from the original Patent 605 to the reissue were valid, but were not infringed by the appellees plant because it employed an element not disclosed as part of the patented combination.
