Appeal No. 96-1238
Application 08/082,177
is a scraped surface heat exchanger. However, we do not
agree with the examiner that the mere disclosure that beta
phase tend hardstock components and beta prime phase tending
hardstocks can be used in combination provides sufficient
motivation to form a beta stable crystalline phase which
comprises 10% to 20% of the composition and consists
essentially of about 25% to about 80% of a beta phase tending
hardstock having an iodine value of less than 10 with a beta
prime phase tending hardstock also having a specific iodine
value of less than 10. We note that the two references do not
provide any specific proportions such as that required by
applicant. Moreover, we do not find any motivation to require
that both of the hardstock blend components have a specific
iodine value of less than 10. We note that the beta prime
phase tending hardstock is disclosed by Reid et al. to have an
I.V. from 0-40. However, neither Reid et al. or Gunstone
suggest the beta phase tending hardstock having an iodine
value of less than 10. We do not find that an artisan would
have motivation to select the lower range of the beta prime
phase tending hardstock having an iodine value less than about
10 in combination with the beta phase tending hardstock having
