Appeal No. 95-0996 Application 07/943,025 173, 178 (CCPA 1967), cert. denied, 389 U.S. 1057 (1968)(“Where the legal conclusion of obviousness is not supported by facts it cannot stand.”). B. The Rejection Pursuant to 37 CFR § 1.196(b) The requirements of the process of claim 1 have been discussed above. Tachikawa II discloses a process for copolymerizing ethylene with an alpha-olefin in the presence of a Ziegler-Natta catalyst system (abstract and page 1, lines 7-10). This reference teaches that these catalyst systems have a high catalytic activity which produces copolymer particles with poor properties (page 1, lines 25-30). Tachikawa II obviates this problem by temporarily inhibiting catalyst activity as a result of contacting the catalyst with an activity inhibitor (page 1, lines 30-35, and page 2, lines 5-9). The catalyst system of the reference is formed by reacting a component containing titanium, halogen, and an organometallic compound such as magnesium, with an aluminum compound and an electron donor (page 2, line 10-page 7, line 13). The activity inhibitor of the reference includes carbon monoxide and carbon dioxide (page 7, lines 14-16).3 All examples in the reference use carbon monoxide as the activity3 inhibitor except Example 5, which uses allene as the inhibitor.
