the ECC capabilities are disabled, enabling the ECC
capabilities subsequent to writing the test pattern, and then
reading data stored in memory using the memory controller,
subsequent to the enabling. The examiner admits that Arroyo
does not disable the ECC capabilities and does not then enable
the ECC capabilities subsequent to writing a test pattern, as
claimed.
The writing of a test pattern must take place subsequent
to disabling the ECC capabilities, according to the dictates
of the instant claimed invention. We find nothing in Arroyo
remotely related to such a claimed feature, and the examiner
has pointed to nothing. The examiner attempts to explain
this, at page 4 of the answer, by referring to a write and
