Appeal No. 2007-0111
Reexamination 90/006,297
1 103. The ‘840 application states (pages 4-5):
2 It has been found, also, that even when ethylene is
3 polymerized with the aid of the special promoters
4 obtained by reaction of heavy metal and metal alkyl
5 compounds, in the ratios proposed for promoting
6 ethylene polymerization, the presence of any substantial
7 amount of the higher olefins inhibits polymerization of
8 the ethylene, while the higher olefins, if they react at all,
9 do so only at very low reaction rates and, in any case,
10 without yielding polymers of the type with which this
11 invention is concerned.

13 104. Original claim 1 of the ‘840 application uses the term “predominates”
14 to quantify the amount of unsaturated hydrocarbons having the
15 structure CH2=CHR, not ethylene.
16 105. The appealed claims do not limit the amount of ethylene in a manner
17 commensurate with the description in the original claims of the ‘840
18 application.
19 106. The description at page 4, lines 1-8 of the ‘097 application states:
20 Although, as stated, the polymerization aids
21 obtained by reacting the heavy metal compound and
22 metal alkyl compound in a solvent inert to the polymer to
23 be formed, such as a saturated aliphatic hydrocarbon,
24 were found useful in the production of high polymers of
25 ethylene, it was not apparent that those agents would be
26 useful in the polymerization of the unsaturated
27 hydrocarbons containing the vinyl group.
