The definition of a perpetual machine is something that keeps on working without any energy input.
See: http://en.wikipedia.org/wiki/Perpetual_motion_machine
According the physical laws, the total mass and energy of the universe is constant. What we see, are the following types of physical processes in the universe:
1.The conversion of mass into energy and sometimes the opposite. For example, mass is converted into energy inside the stars.
2.Not all parts of the universe has the same amount of energy or mass. This inhomogeneity results in the flow of mass and/or energy from one place to another.
3.Some complex systems , like life which converts the chemical energy into other kind of energy like mechanical etc.
In all these above processes, the total mass and the energy of the system of all particles (material or energy) in the universe, remains constant. This is one of the fundamental laws of nature, never have been proved wrong.
So, we can not call the universe a perpetual machine.
The ultimate fate of the universe is a pretty uninteresting state of particles of matter and energy with maximum entropy. As the universe is still expanding, everything will move away from each other and the clusters of matter will be diffused into uninteracting bunches of particles, roaming around the space, for ever.

THERE IS NO SUCH THING AS A PERPETUAL MOTION MACHINE. That said, no, the universe is NOT a perpetual motion machine. Depending on the mass of the entire universe, it might either expand forever, and end in a cold death, whereby everything basically freezes over to something really close to 0 kelvin. Or it will expand, and then stabalize, and then contract again and end in the big crunch.

The universe is NOT a perpetual motion machine. Even in nature, in space, SOME energy is always lost - no supernova or star forming region can be 100% efficient. Eventually, enough will be lost that they universe can no longer support star formation. It's the first AND second laws of thermodynamics.

The universe is not immune from the laws of thermodynamics, and the amount of available energy constantly decreases. We probably have a mere hundred trillion years before star formation ceases. Eventually, even matter itself will decay.

It is destined to come to an end,some time in the future it will go out of existence.
