Merita - does this mean that these cattleya plants developed the dark patches while inside the house?
If it is a cold-temperature-related issue, then getting the situation under control should involve shifting the plants to a growing area where the temperature stays within safe limits all of the time. And then allow the orchid to recover. The patches will remain, but hopefully those region dry up - and then will stay very dark for a while, and then maybe change (in the future) to a dry tan/brown colour.
