Initiating should not matter. By that account, 50/50 partnerships should not exist in the majority of cases. After all, lets be honest, in almost all cases, only one founder can come up with the original seed of the idea. For the record, I don't believe in 50/50 as a standard at all. I believe that fair share should be divided accordingly. Having said that... Filing a patent (which is a lengthy process meaning he doesn't even have it approved yet) does not equate to having more equity. From what I'm hearing, it really should be 50/50 unless he has something more valuable he is bringing to the table i.e. experience scaling and exiting a company profitably before, lots of connections that actually leads to something and not just knowing a lot of folks (which people can attain just by going to a ton of events and meetups; some do), etc... Without knowing the full details, as you have said, and going just by the above, 50/50 should be fair in the scenario above.
