Yes, that's intended to be the great advantage of using Theora.

Though Theora is covered by some patents, there is a permanent,
royalty free license in effect for all uses of Theora - so you don't
ever need to worry about those ones.

Of course, as with anything (software, hardware, or other), there
could be unknown patents lurking - but in the case of Theora, there
aren't any that are known about that could be a problem.

Theora (unlike H.264, and many others) is intended to be usable
freely, for any purpose - enjoy it!
