"a man who understands the road less traveled"
She just seems to mean that she doesn't want an ordinary guy that has an ordinary career (like a banker or insurance salesman) in which that's what defines him in that he doesn't do much anything else noteworthy besides work an ordinary job, relax, eat and sleep.
She wants a man that does stuff that ordinary people don't do. For example, participate in triathlons (like she does), go skydiving, and/or build a unique business that hasn't been done hundreds of times before (like a restaurant).
With that said, there is a cliche that people don't know what they really want, especially when it comes to what they really want in a partner.
So I think she wants a man like what I stated, although because she used the term
understands the road less traveled
takes the road less traveled
she may be fine with an ordinary guy, but just wants him to understand other paths that people may want/choose to take.
Or maybe she has already tried searching for a man that is out of the ordinary, but since she hasn't found him yet, she is willing to settle for a man that at least understands the concept of doing things the non-ordinary way even if he chooses to do ordinary things all the time.
"a man who understands the value of a patent"
She is a patent attorney, so this seems like a pun at the very least. Patents are definitely important if you have an invention and want to reap the money and credit for it. Without getting a patent, someone else could steal your invention and claim it as their own. So patents can definitely be very valuable.
