Grogg wins reversal

Appellant wins in Ex parte Grogg:

We agree with Appellant that Ishikawa does not disclose a power
transfer unit that engages and disengages an auxiliary drive system from a
primary drive system. To “engage” in this context means to “interlock with”
or “mesh.” Merriam-Webster’s Collegiate Dictionary (11th ed. 2005).
Clutch system 13A engages and disengages electric motor 2129 from the
rear-wheel drive system, but the electric motor powers only the rear wheels;
a separate engine 2101 powers the front wheels. Ishikawa, col. 1, ll. 13-17;
col. 3, ll. 16-25, 32-48; col. 8, ll. 27-29; fig. 1. Thus, whatever engagement
and disengagement is performed by clutch system 13A is done entirely
within the rear-wheel drive system rather than between that system and the
front-wheel drive system, as claims 1 and 2 require.
