Appeal No. 98-1591 Application 08/417,625 Lilly’s example 17 (exhibit 10, page 18, line 56), six tests produced both clavulanic acid and cephamycin C which, appellants indicate, is one of Lilly’s desired products (brief, page 9), whereas in six tests, neither clavulanic4 acid nor cephamycin C was made. In the remaining three5 tests, the data are inconclusive. That is, in experiment 6 R204 batches 50/4 and 50/8, the imidazole assay and bioassay showed no production of clavulanic acid or cephamycin C. The HPLC analysis, however, indicated that cephamycin C, but not clavulanic acid, was present. In experiment R204 batch 50/6, no clavulanic acid was detected by use of the imidazole assay, whereas clavulanic acid was detected by HPLC and cephamycin C was detected by use of both the bioassay and HPLC. It appears that the test results which indicated the presence of cephamycin C in batches 50/4 and 50/8, and the test results 4Experiment R201, batches 50/6, 50/7 and 50/8; experiment R204, batches 50/3, 50/5 and 50/7. In experiment R204, batches 50/5 and 50/7, the imidazole and bioassay both showed no clavulanic acid, whereas the HPLC test indicated the presence of both clavulanic acid and cephamycin C. 5Experiments R202 and R203. 6Experiment R204, batches 50/4, 50/6 and 50/8. -7-7Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 NextLast modified: November 3, 2007
