The EPO is concluding that the patent is not novel because of the
publication cited. The patent owner has an opprotunity to rebut that
finding and may be able to appeal if the EPO doesn't accept the
rebuttal. Whether the patent owner will prevail depends on the contents
of the reference cited and whther the patent owner can differntiate
their enzyme from the prior art. One would have to compare the
reference to the patent application to make that judgement.
The process has just started. At this point one cannot predict whether
the patent owner or EPO will prevail. Even if the patent owner loses,
the first round, they may have a right to appeal, and they may have
other patents covering aspects of PCR that would preclude users from
practicing the technology without a license.
